7110 problem

[SmOg]

I have a 7110 wghich has many problems... First when im switch it on the phone starting normaly, but after the startup logo, the display will gone, and asking to set the ring time... Its unable to set the time because the phone will freeze this part of the boot.... I checked the "little" battery witch is in the phone. It has ~2,4V. Is it the right voltage for it?

If the problem is not with the battery than what? I treid to flash a never version, but no succes...

Any tips?
