What Is ClockworkMod Recovery And How To Use It On Android [Complete Guide]

ClockworkMod, abbreviated as CWM, is a popular custom recovery for Android phones and tablets developed by Koushik Dutta (Koush) – a well-known name in the Android dev community. ClockworkMod recovery allows you to perform several advanced recovery, restoration, installation and maintenance operations on your Android device that aren’t possible with the stock recovery, and is one of the most common ways used to gain root access, back up device data, install custom ROMs, kernels, themes & mods, and more. However, for anyone new to Android customization and hacking, some of its options might prove to be a tad confusing. In what follows, we will cover all that this recovery is capable of doing, and how to do it.

Here is what we shall be covering in this guide:

  1. About Android recovery
  2. Introduction to ClockworkMod
  3. Installing ClockworkMod
  4. Booting into ClockworkMod
  5. Feature tour
  6. Using ClockworkMod for ROM, kernel, apps, theme or mod installation.

Now let’s take a look at each of these topics in detail.

About Android Recovery

All Android devices ship with a recovery console that is basically a partition on the device’s internal memory and can be booted into. The stock recovery of almost all Android devices provides a few basic yet handy options that allow you to factory reset your device, clear its cache partition, and recover its operating system using an official ROM in zip format, but that’s all you can do with it. That’s where a custom recovery comes handy.

A custom Android recovery basically replaces the stock recovery with one that lets you do all you can do with the stock recovery, plus a plethora of more options to give you a lot more control on your device. With a custom recovery, you can install official and unofficial ROMs as well as other updates including hacks, themes, kernels etc. using zip files, wipe not just user data but pretty much every standard partition on your device, mount the storage card for USB mass storage access without leaving recovery, partition your SD card, wipe dalvik cache and battery stats, fix permissions, perform, manage and restore backups, and so on.

Introduction to ClockworkMod

ClockworkMod recovery is one of the most widely used custom Android recoveries that is available for most mainstream Android devices. It is our custom recovery of choice here at AddictiveTips and almost every custom ROM that we install on our devices is done using this recovery.

ClockworkMod recovery has been developed by Koushik Dutta (also known as Koush) – the same guy who brought us the Android ROM Manager. He can be found at his blog hacking away at Android devices, and at Twitter.

Installing ClockworkMod

For most devices, ClockworkMod has a dead simple installation process. This method does require you to fully root your device in order to be installed but once rooted, installing it is as simple as installing ROM Manager from Market, launching it and using its first option i.e. the one that says ‘Flash ClockworkMod recovery’.

However, in certain scenarios, the ROM Manager method wouldn’t work, or would simply not be the preferred method for your situation. In such cases, there are several other methods available to install ClockworkMod. We have covered the ROM Manager method as well as all these alternative methods in our guide on how to install a custom recovery to your Android device.

Multiple devices:

Booting into ClockworkMod

Once you have ClockworkMod recovery installed on your Android device, booting into it is quite simple. All you have to do is launch ROM Manager and tap ‘Reboot into Recovery’.

Also, if you have ADB installed on your computer, you can simply enable USB debugging mode on your device from Settings > Applications > Development, connect it to your computer via USB, launch a Command Prompt / Terminal window on your computer and enter this command:


adb reboot recovery

The above methods will not work in certain cases though, for instance if you can’t boot into Android in the first place due to some issue, or if you are using a device like the HTC HD2 that doesn’t natively support an Android recovery. Many solutions are available in these cases.

  • Using hardware button combination on most Android devices:
    On most Android devices including ones by HTC, you can enter recovery by powering your device off and then powering it back on while keeping either the ‘Volume Down’ or the ‘Volume-Up’ button pressed, depending on the device. This will enter the bootloader from where you can select the ‘RECOVERY’ option by navigating to it with the Volume key and entering it with the ‘Power’ key.
    On most Samsung devices specifically Samsung Galaxy S series devices, you must keep both the ‘Volume-Up’ and ‘Home’ keys pressed while powering on the device, to directly enter recovery.
  • Using MAGLDR on HTC HD2:
    Entering ClockworkMod recovery on the HTC HD2 can’t be done via ROM Manager or any hardware button combination but that doesn’t mean it is difficult in any way. All you have to do is power the device off, power it on by keeping the Power key pressed till you see the MAGLDR bootloader’s menu and finally selecting the ‘AD Recovery’ option.

Feature Tour

Now that you have ClockworkMod recovery up and running on your phone or tablet, let’s take a look at all the options it offers you to manage your Android device. We are using a Nexus S running ClockworkMod Touch recovery 6.0.2.5 but the details should apply to other devices and versions of the recovery as well.

This is what you see when you reboot your device into ClockworkMod recovery:

ClockworkMod Main

If you are using ClockworkMod Touch recovery, you can simply tap on these options to navigate between different sections and perform all the actions. On the non-touch versions of the recovery though, you can navigate between items using the Volume-Up and Volume-Down button, and use the ‘Power’ button to enter/launch the highlighted option on most Android devices. On devices equipped with a trackball or an optical track pad such as the G1, G2, Nexus One, HTC Desire etc., the trackball or track pad can be used for navigation and clicking it activates the selected option. Let’s review each of these options and their sub-menu options in detail now.

  1. reboot system now
    This one is self-explanatory.
  2. install zip from sdcard
    This option brings up the following sub-menu:
    ClockworkMod Installing Zip

    1. choose zip from sdcard
      Lets you install any zip file from any location on your SD card. The file can be for a ROM, a kernel, an application, a theme or any mod as long as it is in recovery-flashable zip format. This is the most widely used option for installing a ROM that you have downloaded and copied to your SD card. Entering this option will bring up a screen that will allow you to browse your SD card for the zip file and select it for installation.
      ClockworkMod Choose Zip
    2. apply /sdcard/update.zip
      This option can be used for installation of any official or unofficial update, ROM, kernel etc. that is in a zip format installable from recovery, as long as the file is named update.zip and it has been placed on the root of your SD card (i.e. not in any sub-folder).
    3. toggle signature verification
      This turns the signature verification on and off. When signature verification is on, you will not be able to install any custom ROMs that haven’t been digitally signed to allow installation on the device (most custom ROMs aren’t signed). Switching it off skips the signature verification check and proceeds with the installation.
  3. install zip from sideload
    This option puts the phone into the new ADB sideload mode, allowing you to install zip files from your computer using the ADB sideload command introduced in Android 4.1 Jelly Bean.
  4. wipe data/factory reset
    This option wipes all user data on the device as well as cache. Doing this will leave your phone in the state it was in when you bought it or when any custom ROM was first installed. It will also wipe any sd-ext partition that you might have setup (more on this later). Selecting pretty much any operation in ClockworMod (including this one) will bring up a confirmation prompt that can save you from a lot of potential trouble in case you accidentally select the wrong operation.
    CWM Confirm
  5. wipe cache partition
    Wipes the cache partition of the device to clear all the data accumulated there over use. This is often used before installing a new ROM, app, kernel or any similar mod via recovery.
  6. backup and restore Undoubtedly one of the most important features provided by a custom recovery, the backup and restore feature – also known as Nandroid backup – allows you to take a snapshot of your phone’s entire internal memory including all partitions, and save it on the SD card. Here is how it looks:
    CWM Backup & Restore

    1. backup
      Takes a full backup of your device, as explained above.
    2. restore
      Lets you restore a previously taken backup. Entering this option presents you with a list of existing backups from the SD card that you can choose from for restoration.
      CWM Restore
    3. delete
      Lets you delete a previously taken backup to free up space on your SD card.
    4. advanced restore
      This option is similar to the Restore option but once a backup has been selected to be restored, this option allows you to choose the parts of it to restore. You can choose to restore the boot, system, data, cache and sd-ext partitions, as shown here:
      CWM Advanced Restore
    5. free unused backup data
      Lets you reclaim space on your SD card by freeing up any redundant backup data that isn’t required.
    6. choose default backup format
      Allows you to choose between ‘tar’ and ‘dup’ for the backup format. Leave this one as it is, unless you are sure you want to change it.
      CWM Backup Format
  7. mounts and storage
    Allows you to perform maintenance tasks on all the internal and external partitions of your android device
    CWM Mounts & Storage

    1. mount/unmount /system, /data, /cache, /sdcard or /sd-ext
      These options let you toggle between mounting or unmounting these respective partitions. Most users don’t need to change these options.
    2. format boot, system, data, cache, sdcard or sd-ext
      These let you directly format any of these partitions. Take extreme care with this option as formatting any of these partitions will result in losing all data on them, especially the boot and system partitions. Formatting the system partition will remove your ROM and leave your phone without an operating system while wiping the boot partition may brick your phone unless you restore or flash another one before rebooting your device. To learn more about the contents of all these partitions, see our guide to Android partitions.
    3. mount USB storage
      Lets you enable USB mass storage mode for your SD card right from recovery so that you can connect it to your computer via USB and transfer any files to/from it without having to leave recovery.
  8. advanced
    This section contains a few options most users will not require, though these can come handy quite often, especially wiping Dalvik cache, which is required before most ROM installations. Here are the options from this section:
    CWM Advanced

    1. reboot recovery
      Lets you directly and very conveniently reboot from recovery right back into recovery. This is useful option for certain back-to-back installations that require the device to at least boot once between them.
    2. wipe dalvik cache
      Allows you to wipe the cache for the Dalvik virtual machine (the custom-built Java virtual machine for Android).This is required before most ROM installations and at other occasions too, for fixing some problems.
    3. wipe battery stats
      Wipes the saved battery usage statistics and effectively recalibrates the battery. Useful in various scenarios when Android isn’t showing correct battery levels. This option is not shown in the above screenshot, but is present in many versions of ClockworkMod recovery.
    4. report error
      In case of errors, this feature can be used to save a log of recent ClockworkMod recovery operations on the SD card that you can later report from Android using ROM Manager.
    5. key test
      Lets you press any of the hardware keys to see if they are properly functioning, and to see their key codes.
    6. show log
      Shows you a log of your recent recovery operations.
    7. fix permissions
      Fixes the file permissions for the internal memory partitions back to default. This is very useful as a fix for several errors and Force-Closes that start appearing after you or an application you installed and provided root access end up messing up the permissions of important files.
    8. partition sdcard
      This option gives you a no-frills way to partition your SD card properly for use with ROMs that support data2ext (a very handy hack for low internal memory devices that enables an /sd-ext partition on the SD card to be used as the internal user data storage i.e. as the /data partition). Once this option is selected, you will be given options to choose the sizes for the /sd-ext partition as well as an optional /swap partition on the SD card, and will then automatically format it for you, leaving the remaining space for normal SD card usage. This option will wipe all data from your SD card so use it with caution!

Using ClockworkMod for ROM, kernel, apps, theme or mod installation

While in the complete feature tour we have already shown you how to install a ROM, kernel, app, theme or any similar mod from a recovery-flashable zip file using the recovery options, those of you who jumped straight to this section expecting to get just this information quickly are at the right place!

This guide is primary focused on a full feature tour of ClockworkMod recovery but in our previously written guide on how to flash a ROM or app from a zip to an Android device file from recovery, we have already covered in detail how to use ClockworkMod for installing any ROM, kernel, app, theme or mod using a recovery-flashable zip file. While that guide is based on an older version of ClockworkMod recovery, everything in it still applies to the latest versions and should work flawlessly.

That’s all there is to ClockworkMod recovery so far. We hope you enjoy using it as much as we do!

  • tony

    Please please help. I have just received a druid 2 global, purchased off ebay, that has been rooted using clock work mod. This was not in the description. The phone seems slow, slower than my previous x10. Also force closes and has missed calls whilst in range. Is this due to root? Can it be fixed? I am a park ranger and have no experience with these things. Please please help, any advice that you can give would be much appreciated but please explain it as if I was a three year old. Thanks in advance. Tony

    • http://www.hqraja.com Haroon Q. Raja

      Hello Tony,

      Rooting will not cause your device to be slow and buggy, nor will ClockworkMod. Your phone most probably has a custom ROM installed (a ROM is basically the operating system and a custom ROM is one built by an independent developer) that is buggy.
      Do not fret as you can easily fix these problems because you already have ClockworkMod recovery installed. All you have to do is find a more stable ROM and install it on your phone from ClockworkMod recovery. One such ROM can be downloaded from http://www.mediafire.com/?322r819kh6wsf5h
      Simply download this ROM, place it on your SD card, reboot your phone into recovery and install it. You can find the detailed installation instructions at http://www.addictivetips.com/mobile/how-to-flash-a-rom-or-app-from-zip-file-to-android-device-from-recovery/

      • BC

        I rooted my phone using the the ClockworkMod process and it’s running significantly slow. It’s not because of a custom ROM because I haven’t flashed one yet as there are no stable ones for my phone so far. It’s particularly obvious when locking/unlocking the screen. Already restored it to factory settings but I’m observing the same thing.

        What could have happened? Thanks :)

    A superb guide, as clear as a bell, and as extensive as a TAX audit. This is in my humble opinion a must read for anyone who owns an ANDROID and wants to update the OS with a custom ROM.

    I have one question? How did you get screen shots whilst in recovery?

    Kind regards, Anil.

    • http://www.hqraja.com Haroon Q. Raja

      I’m glad you found this guide helpful. Regarding taking screen shots while in recovery, the only way is to use a tool called ddms, that comes with the Android SDK. We have a guide on that too, which you can check here: http://www.addictivetips.com/mobile/how-to-take-screenshots-of-android-device/

      Guess you mean the app and not the recovery.

      In that case, yes you do need to re-install the app after flashing a new ROM.

    Can be expained what format boot, system, data, cache, sdcard or sd-ext does exactly? Wit hthis I mean, when choosing either one, what will stay and what will I be loosing? With explaining this above, the guide would be completed. (I ask this because many tutorials of custom roms explain me to do this without telling me if I loose apps, widgets, MSGs, etc, or not at all. I’ll hope you’ll explain!

    • http://www.hqraja.com Haroon Q. Raja

      That my friend, is a superb idea! Instead of further lengthening this guide by adding that information here, I am writing a new guide that will explain all about Android partitions, in detail. Once published, I’ll provide a link here in the section that you mentioned. =)

    • http://www.hqraja.com Haroon Q. Raja

      Oh and for a really quick answer to your question…all your apps, widgets and messages etc. are stored in the /data partition and wiping it will mean losing them. Note that if your ROM uses an /sd-ext partition on your SD card for data storage (using Apps2SD+ or data2ext), then /data is basically mapped to /sd-ext and wiping /sd-ext will result in losing all the above mentioned information in that case.

  • mensachicken

    This comment may be completely inappropriate but I won’t know unless I ask. I’m two-days-new to Android so please go easy.

    - Got an HTC Desire Z as a gift (unlocked, and apparently with the Clockwork Mod on it).

    - Am unable to get any data to DL *unless* I’m in a WiFi zone (and yes, the use Mobile for data checkbox is checked).

    - So I thought I’d check if there were firmware updates available. There was; DL it; got a wacky ! inside a triangle when I installed and rebooted to the Clockwork screen. Googled to this page.

    - Now, I told it to run the update with Clockwork and it said no such file.

    - So then I rooted around and found that there is a file in the Downloads directory. I assume this is the file that just DL… however, am a little terrified to run it because:

    a) don’t know anything about Android and what will happen if it’s not the file.
    b) the phone is unlocked and I want it to stay that way and not sure if running the update will affect this (the file name has the name of the official carrier in it, Bell).

    So, should I run it? Is there a way to confirm it’s the file that just DL? (it’s the only file in the Downloads folder). Will the unlock remain without issue?

    And… any idea why I’m not getting any data? I’ve confirmed with my carrier that I have a data plan and it should work (SIM works fine in my iPhone and gets data without a problem).

    Thank you, and sorry if this isn’t the right place to ask this.

    • http://www.hqraja.com Haroon Q. Raja

      If you checked for a firmware update and installed it successfully, it must have removed ClockworkMod recovery from your phone and replaced it with the stock recovery. Though to get data on your phone, that shouldn’t be a problem. Most probably, your phone doesn’t have the required APN settings for your carrier.
      Go to Settings > Wireless & Networks > Mobile networks > Access Point Names
      You will have to add your carrier’s access point information over there. You can get the information from the carrier or from CyanogenMod’s global list of APNs at http://code.google.com/p/cyanogenmod/wiki/APNlist
      As for the file you found in the Downloads directory, you needn’t install it again if you already did the firmware update successfully. As a rule of thumb, never install any file from recovery that you aren’t absolutely sure about.
      Lastly, if you want ClockworkMod recovery back, you can easily install it with the ROM Manager method mentioned in this guide.
      Hope it helps…welcome to the wonderful (albeit a bit complicated) world of Android!

      • Arman Khan

        First of all thanks for being there to answer our questions and help us with getting more out andriod.

        Now to the my query, i bought a htc desire HD online which is rooted and running COREDROID V5.4 custom rom. there is titanium backup, rom manager and some other app that i did not find in my previous stock Desire hd also installed on my device.
        Now i am trying to upgrade to a newer Coredroid Rom V6.5 to be precise, which has some of htc sense 3.1 features in it. their website says that i should backup my phone because this newer ROM with erase and reflash my phone and then partitions the drive with ext4. My main concern is my data. can you please advise me how to backup data from the phone. the ideal thing would be to backup then install the new ROM the restore all the data on the phone to the pre install state. so i dont lose any thing at all but i am not sure if thats possible with android yet.

        Now i am new to this whole rooting and customizing android scene but i am usually good with computers and tech.

        I thank you in advance for your help.

        Arman

        • http://www.hqraja.com Haroon Q. Raja

          It is possible to do that with Android, and here is how you should go about it:
          1. Using Titanium Backup, make a backup of all your installed apps and their data. You may skip system apps and their data.
          2. Connect your phone to your computer, mount the SD card and transfer all the content from the SD card that you want to save, to your computer, especially including the folder containing apps and data backed up by TitaniumBackup.
          3. Sync your contacts, calendar entries etc. with your Google account. Most users have it set automatically by default anyway.
          4. In case you want to backup your call logs and SMS messages, use free app SMS Backup+ from the Market for the purpose.
          5. Now download the ROM, reboot into recovery, wipe all data, cache and Dalvik cache, and feel free to flash the new ROM without the risk of losing your data and apps.
          6. Once the ROM has been installed, sync back your contacts & calendar entries using your Google account, restore your user apps and their data using Titanium Backup (which you may need to install again from the Market first) and finally, restore your call logs and SMS messages using SMS Backup+.
          Following this path, you should lose nothing at all…except for some app-specific data of a few apps (that isn’t uniquely your data) perhaps, which the apps will be able to download again whenever required.

    OK, so I got my new SanDisk 16GB Class 4 at last, from Amazon…..

    Now, I know from lots of sources that there are myriad problems with SD cards, and there are variations relating to the actual phone, the card, etc.

    So, I have decided to Format this card right from the off, as I have seen this elsewhere as a necessary preliminary step.

    Now, I only got the liddle teensy weeny card, with no caddy?? or SD cover.

    I have only got SD slot on Laptop.

    There is a format function in CWR, and I am hoping that I will be able to format the new card there, without ever actually booting into the Android system.

    I use the App2SD froyo, which has the apps in /mnt/sdcard/.android_secure folder.

    I have a complete back-up of all on the existing SD, which is FAT32, including the apps folder shown above.

    Am I being over-cautious?? in wanting to format the new SD card??

    I don’t know if it is currently formatted.

    ***(SanDisk say all SDHC cards will be delivered formatted FAT32)

    If not formatted, will there be a problem accessing it for format in CWR??

    TIA for any and all answers, gotta go…..check in later.

    I will have a full back-up of my existing card on PC, ready to restore to the new card.

    Cheers, Danny

    Haroon,

    You forgot to mention the USB JIG for the samsung galaxy s (and S2) etc. if you can’t put
    your phone in to download mode with all the above mentioned methods.

    Just plug your USG JIG in the phone (when it is switched off) en your phone goes to
    download mode.. then you can go to recovery with vol up!

    Thank you for this manual anyway!

    Hi Harron…..and all

    I went ahead anyway, so here is what I did, hope it helps:

    This is for a ZTE Blade, with Custom ROM Swedish Spring 5, GEN2 by TPT!!!

    I went ahead anyway, having read as much as I could about various dodgy SD’s etc……I actually also registered my SanDisk card with them here:

    http://kb.sandisk.com/app/account/prodreg/alist

    so I have a warranty until 2016…….!!!

    won’t get that from Hong Kong!!!

    I backed up all data on the original SD

    Powered off phone, removed Battery…2B sure 2B sure

    Replaced original SD with new 16GB card..

    Booted into recovery…..

    Choose: mounts and storage

    Options there are:

    Mount: /data…. /sdcard…. /sd-ext….

    Format: /boot…. /cache…. /data…. /sdcard…. /system…. /sd-ext….

    Mount USB Storage

    So, without any hesitation, I chose the Format /sdcard option.

    Took about 3 secs.

    Then I took Mount USB Storage option, (First connected to Laptop via USB).

    Allowed connection on Laptop, checked the Drive (G: in my case).

    Windoze 7 Confirmed….. empty SD card, formatted in FAT32, no errors on drive:

    checkfor errors by right-click on Drive/Properties/Tools/error checking/check now (disable auto-fix[ first time, just in case).

    Went to Blade Back-up folder on Laptop, copied all files onto SD card, (Removable Disk (G): in my case…..).

    Disconnected USB after copy procedure completed successfully…dismounted by clicking on USB connected notification on PC Taskbar.

    On Phone, still in CWR, go back to main menu, choose Reboot.

    When phone powered up, all OK, no probs with apps, so far…..

    Except, this SD card seems slower, even when using SD Speed Increase at cache-size 2048, or 1024….

    Also, CSipSimple used to run OK from SD before, now I had to move it back to Phone, but this is recommended by the Devs anyway….

    I am not sure what Class the original 2GB card was, no indication on card, but the new one is Class 4.

    I have gingerbread installed on my nook color (it is awesome!). However, I am a noob and want to try flashing (I think that is the correct term) another ROM on the nook color? The ROM I would like to flash is the original nook software and keeping the gingerbread too? Is this an option or am I way off base?

    Thanks for the help!

    • http://www.hqraja.com Haroon Q. Raja

      If you flash the original Nook Color firmware (or any ROM for that matter) to your phone, you will lose the currently installed OS i.e. Gingerbread in your case, so you can’t keep both that way. However, unlike most Android devices, Nook Color supports booting an operating system from the SD card as well, so you can choose to install Gingerbread on a separate SD card and use it whenever required. Some Googling on it should easily get you going.

    Hi,
    I installed Clockwork Recovery Mod, but I think I may have chosen the wrong image to flash. Is there an easy way to remove this image and re-flash it?

      You needn’t remove it…just flash the correct image directly by using one of the methods linked in the installation section of this guide.

  • Ron D.

    Just to make sure I understand (and I really appreciate the help) I have another SD card with the barnes and noble OS on it and I have the gingerbread OS on the nook now. I can back up the gingerbread stuff on my current SD, then install the B&N OS on the nook. Every time I change SD cards the OS will change or will I have to go into CWR to install the OS each time? I think I may be a little bit confused but I am willing to learn!

    • http://www.hqraja.com Haroon Q. Raja

      If the SD card has a bootable installation of any compatible OS, the Nook Color will boot that OS, ignoring the one installed on the internal memory. You should therefore not require to install it from CWR each time. That’s why you should keep a separate SD card for daily use with the OS that’s installed on the internal memory, and use another SD card for booting into another version of the OS whenever required. Hope it helps.

  • Allison

    When I reboot into recovery, it takes me to the first clockworkMod recovery screen, but when i select anything it takes me to a page with nothing on it but the clockworkMod symbol, i have a previously rooted optimus V. The os on it atm is VM670-20110516 and I need to go to VM670-20110601 but cannot because i cannot select any option.

    • http://www.hqraja.com Haroon Q. Raja

      I haven’t used that device but in my experience, on some phones (especially those with trackballs or trackpads), using the power button does not work for selecting options in ClockworkMod recovery, and you have to use the trackball/trackpad button. Using the power button merely hides all the options and shows you just the ClockworkMod logo. You should therefore try using other hardware buttons to see if they work for selection. Hope it helps.

    I installed CMW and used it to load the tether update from teamblackhat. The update was not successful (stuck on NV update 1 of 4…), so I have to do a battery pull. After reboot, phone is fine. However, if I reboot the phone AFTER recharging, I’m always thrown in the the CMW reboot screen and I have to select “reboot”. This happens after every recharging I do. Does CMW think that a previous update was not successful and that is why it keeps coming up and how do I stop this strange behavior?

    Thanks for any advice!

    Hello Haroon,

    Thanks for the guide. I’m having trouble with my old Desire.

    Following another guide somewhere on the web (in french, which is my mother language), I rooted my phone (this point seeming ok to be), then used Unrevoked 3 ( http://unrevoked.com/#desire ) to put the latest ClockworkMod for this HW (namely the 2.5.0.7) (I didn’t know at the point that ROM Manager existed).

    When I boot on Recovery mode, I get ClockworkMod, fine… but it keeps giving me these error messages :

    E:Can’t find MISC:
    E:Can’t mount CACHE:recovery/command
    E:Can’t find MISC:
    E:Can’t mount CACHE:recovery/log
    E:Can’t find MISC:

    Not knowing much about this tool, and having found no warning whatsoever in the guide about such a possible outcome, I simply shrugged and went my way with the next steps, which were wipe data/factory reset, plus wipe cache partition.

    Then I went with the procedure to install Ginger Villain… as you can imagine, it went ultra fast, ended with a nice “Installation complete” message (or something very much alike anyway).

    I was already asking myself a lot of questions – I’ve never flashed the ROM of a phone, but I’ve got a degree in computing science so, in a way, I’m not totally a newbie (if only a bit impatient and careless ^^) and seeing such a quick installation made me wonder… I rebooted anyway and … not to my surprise…

    - the custom ROM was not installed

    but much to my surprise…

    - my personal data were not deleted (in other words, no factory reset)
    - all the apps that were on the internal card were still there and fully functional
    - all the apps that were on the SD card were still there, but seemed to the system not to be installed anymore… installing them again from the marketplace solved the problem, i.e. all the parameters were still there “somewhere” (so … I guess the wipe worked less than well ^^ )

    Now, I’m not sure what to do next, and what the problem really is. I guessed from the “E:Can’t mount CACHE:recovery/command” error message that something went wrong with the installation of the ClockworkMod. After a while googling, I came upon this post and discovered ROM Manager, so I went on with the installation, flashed again the Recovery… and it doesn’t solve a thing… and then I took a look at your excellent other article about the partitions and went with a terminal to look a bit at the phone’s internal card… much to my dismay, it seems something is quite not correct or not standard looking :

    http://www.varkhan.com/varkhan/docs/PUB/screenshot_5.png

    As you can see on the shot, I don’t have (or at least don’t see with an “ls -a”) those partitions :

    boot
    recovery
    misc

    perhaps they’re not supposed to show up, but it’s already bugging me. Of course, my phone boots and gets into recovery mode, so the partitions are there somewhere. But as Clockwork gives those error messages… perhaps… in other words, I’m completely at a loss even to know where to go now to find a solution to this problem.

    However, the phone is still working 100% well with the stock 2.2 ROM so it’s not exactly unbearable. It’s just frustrating to have rooted the phone, therefore losing the warranty, to no avail…

    Haroon, you seem particularly tech savvy so maybe you have an idea ? Or anyone else of course…

    TIA
    G.

    What is up with this ClockMod Recovery program?
    I installed it a few days ago on my Dell Streak 7 and today I decided to reset to factory so I ran the “wipe data/factory reset” and now the tablet only boots into ClockMod Recovery menu…
    I am not a happy camper about this… I tried the hard reset button but nothing seems to work.
    Unless I can find a way to boot into the system this ClockMod Recovery basically ruined my tablet.
    Once I can get it to boot then I certainly will get ClockMod off my tablet. As far as I am concerned it is a piece of crap. My tablet will not sync with my computer, I can’t shell to a terminal so I have no way to get the the HD or the system.

Please me in getting 3G signal in india.

    here are the details of my phone

    Android version 2.3.4

      That is the space occupied on your SD card by the backups you took from ClockworkMod or ROM Manager. You can find them in a folder called ‘backup’ inside the clockworkmod folder on your SD card. You may remove the backups you no longer wish to keep.

    hi, was trying to update ClockworkMod-Galaxy5-v0.5.tar to my samsung gt-i5510 using I5510_Odin_Multi_Downloader_v4.34 & CALLISTO_v1.0.ops. though the update appears to have completed with odin displaying “pass” in blue background, i have obviously done something grossly wrong.
    however my device does not boot up anymore. it just endlessly flashes the “samsung” splash for 3 seconds every 5 seconds. if i connect it to the usb of my laptop then the “samsung” splash disappears and the backlight starts flashing every 5 seconds.
    i have tried booting into download mode:
    a. without the battery keeping volumedown+home+power pressed and then inserting the battery
    b. connecting to the laptop usb without the battery &inserting the battery with  volumedown+home+power pressed.
    nothing seems to work, please help me restore my device please, thanx. would like to add the running firmware on my device was ‘i5510DDJK4′btw, my device was rooted using universal androot from the google market.

    OK, I got a doosie. Bottom line is when I reboot into recovery, I get the exclamation point inside a triangle, with little android guy, and have to hold down power button long time and _then_ boot into clockwork mod. That’s not right, is it? Here is the detail: Got my SGS2, Sprint, rooted, using ZedoMax’s method (Odin, flash his ROM, voila: rooted). But then had trouble flashing Clockwork Mod. Recovery 3e requires signature verification for flashing external files, so it’s barfing, throws error can’t read file signature, hard stop. SO, had the brilliant (?) idea to try replacing the ROM with his new one: SPH D710_Zedomax_EpicTouchKernel-v2.tar. Did that, and now when I boot into recovery it gives me exclamation point inside triangle. Then when hold down power button for several seconds it actually _then_ goes into Clockwork Mod (orange menu). Research let me to  a version that seemed to hold promise it would not hang: acs-eb30-clockwork-epic-touch-4g-sep-20-4-00-pm.tar.Flashed it, and then got  latest build from Zedomax: SPH-D710_Zedomax_EpicTouchKernel-v3.tar. flashed that. But still, recovery doesn’t go straight to orange menu, which is not right, right? I know, I’m a noob, but I can’t even begin to explain how much time this has taken. Thx to anyone who can help.

    Is there any workaround to this?

    • http://hqraja.com Haroon Q. Raja

      CWM doesn’t automatically creat an ext partition on the SD card. You have to manually create it using CWM’s partitioning features or the program of your choice. CWM just shows it in mounts-and-storage regardless of whether the partition is there or not, but works with it (backing it up and restoring it etc.) only if it is actually there.

    after i select any option in the clockworkmod recovery screen it goes to a screen with the clockwork icon and it just stays on that screen, how long should it stay on that screen?

    • http://hqraja.com Haroon Q. Raja

      I’m afraid you must be using the wrong button to select the option. If all options disappear and you only see the clockwork logo in the background, that means the button you are using isn’t the selection button. On most phones, the power button is used for selecting the option, though it may be a different one in a few. If you have an older phone with a trackball (like Nexus One) or optical trackball (like HTC Desire), press it to select. Hope that helps.

    hi guys does Alcatel One Touch 918N compatible with clockworkmod recovery? Or some link for compatible devices thanks..

  • smetje

    I have a big problem. I am in ClockworkMod Recovery, but nothing is working. No mather what option I choose, i just get a picture of the black head and the orange arrow. What can I do? Even after removing battery and restarting, i have the same. Help me.

      I’m afraid you must be using the wrong button to select the option. If all options disappear and you only see the clockwork logo in the background, that means the button you are using isn’t the selection button. On most phones, the power button is used for selecting the option, though it may be a different one in a few. If you have an older phone with a trackball (like Nexus One) or optical trackball (like HTC Desire), press it to select. Hope that helps.

    Which items in mounts & storage should be Mounted by default?
    Thanks!

    • http://hqraja.com Haroon Q. Raja

      Whichever are mounted by default when you get there after booting into recovery. Everything gets unmounted and remounted upon reboot so you don’t need to worry about how you leave things mounted/unmounted there. Those changes are for that boot only)

      • solomonsright

        Thank You for your answer, it is greatly appreciated! They say that; “A Good Deed never goes unpunished” ;-) so I have a follow up question…. When I run a nandroid backup, at the end there is a message saying that “the external sd (or memory, I can’t remember) could not be found.. skipping”? yet the nandroid backup IS stored on the external sd card?
        Is this correct?
        BTW, my phone is a sgh – i727R which had to use the T- Mobile “image” when I rooted my phone back in December, as CWM does not have any for my phone.

        Thank You again!

  • Ruben Cossyleon

    Hey, i really need some help… All im trying to do is go from a custom recovery that a previos owner of my phone has to the stock, because i need to be able to swap my old phone number to this phone! please help!

    Alright, it seems you usually respond to comments, so…

    I’m having an issue with my phone, for some reason I cannot boot into the recovery thing in the “Bios” or whatever it’s called haha…

    I know I have booted up CWM before because, I’ve made a backup with it before when I flashed my phone and unlocked it. I’ll tell you what I’ve done, and hopefully, maybe you can guide me through whatever it is I’m doing wrong.

    First thing I tried was, ROM Manager (because I forgot I had ever already installed it…) I installed it through this app. Then, of course, I touched the “Reboot into Recovery”. My phone restarted. Like, completely back to my home screen…

    Then I remembered “Oh wait, I know I’ve installed this before and ran it before, I’ll go turn my phone off, hold the -volume button down while I power up and choose the recovery thing in there!” Sooo, that’s what I did. My phone restarted, completley, again, and I’m having a really hard time getting into recovery.

    If you could help, that would be greatly appreciated, thanks so much in advanced!

    I have a Droid 2 Global that is currently stuck on the M screen. I backed up using ClockworkMod, but now I am unable to get into ClockworkMod recovery. I am, however, able to get into the stock Android recovery using the hardware keys. Unfortunately, this doesn’t allow me to use the ClockworkMod backup. Any suggestions?

  • Hadi Bou

    A nice intro for a begginer, thank you

  • Noah

    So if I update CM 9.0.0 to 9.1.0, all I have to do is apply is click Install ROM from SD Card? And obviously take a backup, do I have to flash or anything? I done it once, but I forget how to now..

  • e154037@gmail.com

  • karl diestro

I bricked my phone, huhu, my phone is cherry mobile nova simmilar to commtiva z71.Please help.

  • B Hiram

    Is there formal documentation from the developers somewhere that explains this applications features? The website is kinda sparse. They don’t seem to have ROMs for the Galaxy Y either. Does installing CWM remove the stock recovery image? If I install CMW can I still go back to the factory image. Is CMW uninstallable?

  • PizzaMan92

  • Bridget

    A cell phone store clerk wiped my sister-in-law’s G2 phone clean and we set it up with my SD and SIM cards. But, now it won’t shut down. If I try to turn it off, it goes back to the ClockWorkMod Recovery pane. How do I make it turn off? Thanks so much!

  • Shobhit Saxena

    I have experience on rooting (installed CM 7.2 on Wildfire) and after reading this post I will say – your post is near perfect.

  • Tommy
