Sony ericsson k850i wont swich on switched on phone. keypad lights up. nothing else. one hour later, digits are still lit, and still nothing else. second k850i to do this. why sony, why? only keypad light and ring around camera glows. nothing appears on screen.

Go to the sony ericsson service center and get it a software update

Use A2 uploader then flash with FS and MAIN and CDA... then its done... if you cant then send your fone to me....

The only problem with doing a software update is that the phone is technically not on so the computer won't recognize it, thus you can't do a software update....unless someone has figured out how and if the have please tell me how
