So I had a perfectly rooted Galaxy Y w/ Android 2.3.6, but then I can't remember why, but I changed in some system files and my device is no longer rooted. I've tried everything but nothing resets all system files. Is there any way I can reset everything, like all system file?

  • Flash a system image via Odin. This will replace your whole system and leave your data intact. Search xda-developers for your phone. There are many guides on how to flash a stock ROM and rooting it. – GiantTree Apr 21 '15 at 18:58

This may wipe all user data!!!

So make a backup just in case!!!!

You need to flash your appropriate firmware package of your device, download it here:


Download Odin (google it) Open Odin (duh)

Reboot your phone to download mode.(google it if you don't know how to)

Connect your phone to the computer

Put the firmware package in PDA/AP

Klik start to begin and your phone will reboot with "new system files"

Hope my answer helped.
