hello

My X800 wont boot up
Just show panasonic logo and shut down with beep sound
then restart automatically loop forever and everrrr

I tried call answer button, * button, and '3' button , but nothing happened

Is there any way to format X800??
please help me out...

If you could get the phone to boot up, then dialing **7370# would reformat the phone (or, at least it does an X700). The answer/*/3 method works only with Nokia's Series 60 2nd Edition phones.

If you remove the memory card and try to start the phone again, and it is not enough to get it to a state where you can reformat it, then I don't think you have any other alternative than finding your nearest Panasonic service/repair center.
