The phone would reboot after a period of time in NORMAL mode. I think an app installed is triggering the event, after the reboot any changes you made would revert the phone settings files to it's last state (kind of similar to Windows TEMP profile) wherein it is not remembering or saving any changes made to it.
I have tried anything I can find in the internet including flashing variou PIT and TAR files but none worked. So I tried grabbing a logcat and just let it run until the phone does the reboot.
Currently the phone can boot to SAFE mode and will not boot not until I try to uninstall ANY application that was downloaded by the previous owner. Worth mentioning also that even after factory reset and performing wipe via stock recovery is of no help at all. I can get to download mode and recovery mode with no problem it's just with the reboots and reloading of it's last state is the problem.
I am suspecting that this thing maybe suffering from a bad NAND set to R/O but I can't conclude yet until I can have the logcat be read by someone who knows how to. I am not a developer knows not much about codes so any help will be appreciated.
I have read about this issue in this thread http://forum.xda-developers.com/show....php?t=2562596 and found no solution yet so I am trying my luck if there is anyone that can help. TIA.
