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.

    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..

  9. OOOOOOMMMMMMMGGGGGGGGG thank u so much my phone had a boot loop for froyo ROM cyanogen & ROM and the motafoca ROM but its fixed after the last step, thanks again

  10. My phone is not starting.or even when I try to ccharge it the battery sign doesn’ appear.mi was usin my phone completely normally with vanilla rom.I booted it several times and it was starting normally.but I once powered it of and the next thing I knew it wasent even starting

  11. 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.

  12. does anybody care to reply over here??
    my phone cant get to recovery mode… can anyone help?? please… coz this is my first android…!!

  13. mine doesnt even start… its stuck in the cyanogenmod boot after i installed it without wiping mem… so all i can do about my dell xcd35 is use it as brick is it??
