Thank you very much for your help, the problem is resolved and my camera is back to factory default.
I do not have the service manual, so I wasn't aware about the above pages.
Forgot to mention that my camera is the G80 and is giving me the "error 0A" when press the WB 2 times in order to restore it to the factory default.
Anybody has any idea has to resolve it?
Thank you,
George
