How To Un Brick Android Phones [Boot Loop Fix]

Although it’s really cool to root your Android phones, flash custom ROMs and do system-level tweaks, but at times we also end up with a brick. Bricking of an Android device means that your phone is unable to boot or keep on rebooting. In case you are unable to start your phone at all, then it’s probably time that you should abandon it all together or try to claim guarantee etc. But if your phone is either on a boot loop fiasco or you are able  to boot into recovery, then you can do stuff to make your phone function normally.

Devices usually turn bricks when either you flash the wrong radio or some corrupted firmware file. It is important to check sum data to verify Firmware file’s integrity.


Here is the step by step guide for unbricking your Android device if it is boots but goes in to a boot loop:

  • The first step is to boot your phone into recovery.
  • Now go to WIPE while in recovery mode and clear Delvik Cache.
  • Now restart you phone and see if it stays alright or goes back into a boot loop.
  • If the phone again restarts after landing on launch screen, then power off you phone.
  • Restart your phone into recovery again and delete all data/cache. Flash a new ROM if it is already on your SD card.
  • Once this is done, reboot your phone and hopefully you will be able to get rid of the boot loop problem.

In case your phone is booting into recovery rather than normally then again repeat the steps mentioned above. In this kind of brick, you will need to re-flash a new ROM. The above method is applicable on temporary bricks only. In case your phone doesn’t boot at all after rooting or flashing custom ROM or boot image, then there is nothing you can do about it. Please check your carrier or mobile phone vendor for a replacement.

    If the phone doesn’t get into recovery mode, then you can use it only as a brick. Buy a new one and next time, remember to completely wipe it before you try to load new ROM. Or just don’t load a new ROM. It’s the safest bet.

    plz help
    i m a noob
    have i bricked my phone? idont know..plz help
    my device is micomax a57(ninja 3)
    this is i have done step by step..

    1> successfuly rooted my device..it comes with superuser and power saver

    2> without restarting..i have installed rom manager and titanium backup..
    (have’nt backuped anything yet)

    3> opened rom manager and flashed clockworkmod recovery..
    it was asked to choose a device from the list and my device (micromax a57) was not listed so i had choosed micromax A70 which was listed…it completed successfully.

    4> than i choosed to “reboot into recovery” option in rom manager..

    5> and the mobile shuts off and after a while “superfone|ninja3″ is displayed on the screen (which is the normal procedure of booting) but at this time it stuck there as if it gets hang….
    6> i remove the battery ..re install it and switch on the power button but nothing happens…
    7> i remove the battery again and then reinstall it again and this time on switching on the power button the phone starts and every thing is fine..

    8> i am so freaked out that i decided to “reset in factory” and after doing that the same point 5> happens again
    and i have tryed to go into recovery mode by pressing volume up and power key but the same point 5> happes again

    9> than repeated point 6> and 7> and everything was fine again..

    10 > agian i thought i have flashed wrong or uncompatible clockworkmodrecovery version..so i agin tapped the “flash clockwokmod recovery “option in rom manager and flashed with some another device (not remembered )
    it flashed successfully but no problem solved..the phone is still behaving as before (all the points 4> to 9> )

    11> remember that i havent backed up any thing yet

    12 >finally i open titanium backup and to clear some ram i uninstalled some apps (that is backed up with titanium backup)

    and now i cannot see my wallpaper and what i can do with my phone is the following

    i> can lock and unlock with power button (sliding it to unlock)
    (at this screen i can see time , installed sim card name, and emergency call option at below)
    ii> i can see notification bar and can slide it

    iii> can connect to pc
    iv> long pressing home touch button …gives me two options
    a> manage running applications (i can access this application)
    b> clear rescent applications.
    v > can recieve calls but cant make calls (havent tryed the emergency call option)
    [i cannot see icons and desktop , its black]
