Hello fellas, got a problem on my set today after using it over 1 month without any previous problems. Just posting it here as a record, I guess. Here goes....
I am using an AP set with KH3 firmware (flashed about 2 days ago). For the record, I always flash the latest firmware as soon as it's out on samfirmware so I've done flashing a fair number of times.
Was out with a friend today, as usual I always check my phone to see if I have any missed call/sms. Around 8pm today, took out my phone, it was unbelievably hot and I mean HOT for no apparent reason. I managed to observe that I got a missed call from home (at this time the phone was already mysteriously in a bootloop). It kept rebooting itself, but it's not a normal bootloop (As I experience before on my galaxy ace, bootloop means it'll just get stuck on the loading screen and will keep rebooting itself). The 'bootloop' I experienced today is such that the phone manages to get into the Enter PIN code screen (The notification area was displaying the usual 'Scanning Media... blablabla, hence I manage to see the missed call notification). The touchscreen was non responsive here and it just reboots itself.
So, what I did was to remove the battery cos the phone was really HOT and I read before on xda developer that some fella's phone actually melted on the area just below the camera (with picture proof). Waited for a while and reinserted the battery. The phone was still rebooting into the Enter PIN code screen and getting stuck there with touchscreen still being non responsive. Removed and reinserted the battery about 4-5 times, still same problem.
Luckily I am rooted with CWM recovery. Tried to enter recovery mode and BINGO, managed to restore my CWM backup file I did yesterday midnight. The phone is fine now. Just lost some data with my Traffic Counter (Cell, Call and SMS data restored to yesterday midnight's point)
I certainly dunno what the heck happened and it was quite an unpleasant experience...... Just sharing, not sure if it's KH3 problem as I never had any problem before since I started using SGS 2.
Frightening experience ; I am on Modaco GR5 XXKH3 , 2 days already - very stable, everything is OK
