My Galaxy S battery died last night and I put my spare in and powered it up. The 'enter PIN' screen came up but I didn't enter it as I was in bed, tired, and feel asleep. In the morning the screen was blank. I re-booted it and the coloured swirl screen comes up, the music plays and it goes to the screen with a big S in the middle. It never gets past this screen. It hasn't totally locked as the colour of the 'S' is changing. After a minute or so the screen goes blank and the 2 LEDs behind the menu and back buttons are the only indication that it's on. Any ideas other than 'Factory reset' as there are photos etc on the internal SD which I haven't backed up :-S
My only idea at the moment is to possibly factory reset it then run a Windows file recovery on the internal memory to retrieve the files.
