To restore back to stock..
After installing the guru reset and choosing to flash stock recovery my phone boots up to android 4.2.2. Afterwards I'm able to receive OTA updates and the first two minor updates are installed without any problems.. However when the 4.3 update with sense 5.5 is installed, my phone ends up in a boot loop.. I've tried this a couple of times and the same thing always happen
I've even tried restoring via nandroid backup instead, and then manually flashing the stock recovery, but the same thing happens again..
I read someone having the exact same issue here:
Anyone know what could be causing these problems? Has it got anything to do with hboot 1.57?
