Hello i have a panasonic x800 with Symbian Series 60 operating system. I was doing a rstore backup from pc to mobile and i dont know what happened and mobile phone now is giving me system error and caanot use it. Is it possible that i re-install again the operating system.

Nokia have an update feature which helps in this sort of situation. Not sure if Panasonic do the same thing.

Does it boot up? Try doing a format if you can.

Hi no even if just connect charge and switch on automatically without the sim card error show "system error"

i think you should try to contact Panasonic Help Desk.
