I was upgrading to the latest version of Google Mobile Maps when my N95 rebooted itself. After starting up again, I would get the Nokia logo then nothing but a white screen. Removing the batter and SIM card didn’t help fix the issue either.
So after some Googling I found out how to reset your N95 back to the factory defaults while in a broken state. Turn on your N95 while holding the ‘3’, ‘*’, and ‘answer’ keys and it will go through the reset process and you’ll get back to the setup screen.
Hope this tip helps someone else searching for the solution.
