I installed a game on my Samsung galaxy s2 using an .apk file.
I was playing a while, and after a couple of minutes my phone rebooted and got bootlooped.
Now there is no boot-loop anymore, but it stucks on Samsung logo.

  • I can get into Recovery mode/Download mode.

  • My phone has a "PhilZ Touch 5" recovery.

How can I revive my phone?

The usual way of fixing bootloops is doing a Factory Reset (via Recovery mode). Of course, you will lose your data.

But seeing that you have a custom recovery, do you also have a custom ROM installed? If yes, try (dirty) flashing the custom ROM via custom recovery. Don't forget to wipe cache and Dalvik cache.

  • Can't I just uninstall the problematic app somehow? – Omer Eldan Jun 20 '14 at 13:49
  • @OmerEldan Are you on a custom ROM? – geffchang Jun 20 '14 at 13:50
  • Yes, but I don't remember the exact ROM name and version. @geffchang – Omer Eldan Jun 20 '14 at 13:52
  • @OmerEldan To uninstall, you can probably delete it from the /data/app folder via recovery. You can try, but I'm not sure if it'll work. Can you check? – geffchang Jun 20 '14 at 14:06
  • @OmerEldan The newly installed app and its data is not necessarily what got corrupted. If you need the phone to be usable a.s.a.p., in recovery do a nandroid backup and wipe data/factory reset. You can worry about getting your data out of nandroid's .tar backups later. – Chahk Jun 20 '14 at 14:56
  • @Chahk Unfortunatly I cannot get into recovry mode now. What should I do? – Omer Eldan Jun 20 '14 at 15:16
  • @OmerEldan Can you get into Download mode? If so, you'll need to flash Samsung's stock image via Odin. – Chahk Jun 20 '14 at 15:19
  • @Chahk Yea, I can. Will I lose my data if I'll flash a stock ROM ? – Omer Eldan Jun 20 '14 at 15:21

    @OmerEldan Yes, Odin wipes all user data. Unfortunately without a functioning recovery image there is no way to backup the data. You may want to try flashing only the custom recovery first to see if that will allow you to boot into recovery. Galaxy S2 section of XDA-developers forums should have the recoveries in Odin format. Be sure to download for your exact phone model, as there were quite a few variants under the "Galaxy S II" branding. – Chahk Jun 20 '14 at 15:26

    @OmerEldan Make sure the USB drivers are good. 99% of all Odin failures are because of bad drivers. Uninstall all current Galaxy S2 drivers (including Kies if you have it) then download and install the latest ones, and try flashing again. – Chahk Jun 20 '14 at 19:12
