I followed instructions here to root it, which worked, and installed Titanium backup to wipe some bloatware and do the backups. I did not flash a rom or do anything else. It was working fine for several months until this morning. It had turned itself off while charging overnight. At first when I switched it back on it flashed "Samsung Galaxy Fame (model number etc)" a couple of times then died. I took out and replaced the battery and sim; and removed the external SD card, and tried again - it flashed "Samsung" once and is now completely dead.
Where should I go from here? Novice-friendly / idiot-proof advice please.
I have the Titanium files on my dropbox, do I need to do anything with them to stop them being wiped or overwritten or..??
Thanks very much.
