Phone: Samsung Galaxy S3 (GT-I9300)

Per work policy to add an exchange account I had to encrypt my phone. After doing so, I needed to root it to create a swap partition as it was constantly running out of RAM. I did what I had done in the past which was to flash CF-Auto-Root with Odin3. After the process finished, the phone restarted and I was shown the usual screen for entering the PIN/Password, so I did and it accepted it showing the unlocked Android icon, but instead of booting to the OS, it froze on a black screen. I have tried flashing the stock firmware, which has had no effect. I have managed to flash the ClockworkMod Recovery, but since everything's encrypted I could not get access to any data.

Does anyone have any ideas?

Thanks in advance,

I ended up flashing the Stock ROM (using sammobile.com) back again and using the Stock Recovery to do a factory reset as the Team Win Recovery format didn't do anything. That did the trick, but of course all data is gone too. Oh well.

have you tried to wipe your data/cache + dalvik? For my experience, sometimes the black-screen is due to a bad-flashing procedure (not your fault) when something goes wrong. If you did not tried yet, try and let me know!

  • I've tried wiping the cache + dalvik, no change. I'd rather avoid wiping the data and lose it till I see that I have no other choice. I've also wiped the /system and then reflashed it with the Stock ROM, no change. Also, checking the ClockWorkMod Recovery log I see that when attempting to wipe the dalvik-cache, it couldn't find the folders: '/data/dalvik-cache', '/cache/dalvik-cache' and '/sd-ext/dalvik-cache'. Is there a way I could backup everything (perhaps via ADB), wipe the /data and then later attempt to restore?

  • OK, I now wiped /data, /cache and /dalvik-cache using Team Win Recovery, and there's been no change at all. I still get the screen to type in my password and when I do, I get the black screen again.
