Today I found myself in one of those annoying yet typical situations! I was off out into the city centre, with arrangements to meet someone who I would call on arrival. I reached for my fully charged phone (Nokia N96) and all the butons, menus and icons had disappeared. None of the keys responded at all (other than the camera key which was little use to me in this situation). On my return home, taking out the battery and plugging it in to the power supply didn’t help at all. All the reset methods (soft/hard) require you to have access to the phone keypad and menu’s (a luxury I didn’t have). However I managed to find an alternative key sequence method to completely reset and re-install the symbian OS.
