One morning I awoke to find that my phone was off after having a full battery and being turned on the night before. I tried turning it on and the only thing that happened is that the screen lights up and the blue Nokia Logo flashes on the screen; the phone then turns off and back on repeating the logo about 4 times before finally turning off for good. Plugging in a charger will cause the phone to do this minus the lit up screen. I've tried a completely new battery as well with no improvment. Any suggestions?

You have WSOD aka White Screen of Death.

Have you tried removing your MMC and Sim Card and powering up yet?

Unfortunately I have.

Either needs flashing, or if you can get it to boot at all, quickly type *#7370# into it

Did you install any new application or game recently? Press and hold the pencil key and then switch on the phone. It may work.
