Here’s how to get started with customizing your LG Optimus One by rooting it and installing ClockworkMod recovery to it. If you don’t know what purpose this will serve or just want to know more about rooting and custom recoveries in detail, see our top 10 reasons to root your Android device as well as what is ClockworkMod recovery and how to use it.


Disclaimer: Please follow this guide at your own risk. AddictiveTips will not be liable if your device gets damaged or bricked during the process.

Requirements:

Procedure:

  1. Download Z4Root from the above mentioned link and transfer it to your SD card.
  2. Open any application manager with the ability to install apps from APK files (e.g. Astro File Manager) and use it to install the Z4Root app from the APK.
  3. Launch the Z4Root app and tap ‘Permanent Root’. The screen should go white for around 30 seconds, after which the phone will reboot.
  4. Your device should be rooted now. Go to the App drawer and click on the z4root icon again to confirm. The application should now say ‘Re-root’ or ‘Un-root’.
  5. Now that your phone is rooted, download the ClockworkMod Recovery image from above and extract its contents to the root of your SD card (not in any sub-folder).
  6. Enable USB Debugging on your phone from Settings > Applications > Development and connect it to your computer via USB.
  7. Launch a Command Prompt / Terminal window on your computer and enter the following commands:

    adb shell
    mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
    cat /sdcard/flash_image > /system/bin/flash_image
    chmod 755 /system/bin/flash_image
    mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
    flash_image recovery /sdcard/recovery.img
    reboot recovery

The recovery flash is now complete, your device will reboot into ClockworkMod Recovery after the last command is entered and will allow you to perform any of the advanced recovery operations ClockworkMod provides.

    A few days ago I downloaded ClockworkMod Custom Recovery on my rooted LG Optimus one. As soon as I clicked “backup” the phone was bricked. I’ve read about people having had the same problem. What’s with that?

      same thing happened to me. I My phone got stuck in fastboot. And this method is not working either. Instead of opening in recovery, the phone performs a factory reset. So annoying.

    after typing “shell adb”, you must type “su” to get to root prompt #. This wont work from $. If you get an error after “su”, and you are using “superuser” for root, use that superuser app to allow adb.

    just a note, Z4Root will not work if you have 2.2.2 on your optimus one, which is how they ship these days.  fortunately gingerbreak does work.  took awhile to figure this all out… here’s a post about it with a link to the version of gingerbreak that works (or at least worked for me):
