A friend of mine just brought me his SGS to look at it, it's in a constant start up loop, gets to the "s" then back to playing the music "s" for a few secs then start up music again
Its a stock Uk o2 he's not really into messing with his phone and as far as I know it was on ginger bread updated recently with Kies, thats as good as it gets for info
First thing I did was, into recovery mode, clear cache and reset to factory, this made no difference
Got into download mode
I had a copy of JVO that I knew worked when I had a SGS so flashed it with Odin and it was the same, tried it with re partition ticked and JVO bootloader and still the same.
Got darkys 10.2 and flashed that instead, it got to darkys start up but froze
I also flashed the dbdata.rfs still the same
When I do a reboot using recovery mode I get an error "cannot mount /data"
