While I was installaing a .sis file, the progress bar stopped and my p800 didn't respond to any input.
A pressed the power button for 10 seconds and restarted it. At the beginning everything seemed ok, but soon I realised the phone didn't answer to input once again (anyway menus were correctly displayed).
I restarted the phone again. At first the screen became blank, no sound or startup animation displayed.About one minute later suddenly that animation was played, and after other 2 minutes appared the menu asking for operating mode (flight mode, phone on).
Don't matter which mode I choose, anyway the screen becomes again blank for a couple of minutes and the flashing "crash screen" whit the yellow alert triangle is displayed.
What can I do?Is there a way to do a master reset whitout the phone working?
