Mine is an AT&T locked i747 phone which I unlocked in India, but haven't rooted.
I had the same problem as above; I charged it all night as usual, but in the morning it was frozen on the logo splash screen. Tried restarting a few times, but it would again freeze on the same screen. So I removed the battery and let it rest a bit, but the same thing continued. Eventually during the course of the day, it stopped booting and now nothing happens when I restart it, it just wont boot.
When I insert another S3 battery, the flash "flashes" for a second and disappears, but the phone still doesnt turn on. Any idea what could be wrong? Battery is probably not the problem, since a working battery from another phone is not helping.
Any help will be much appreciated
