After update of my C6-01 from Symbian Anna to Symbian Belle,most of the softwares are not supported. Google Maps,Skype Crashes. Is there any otion for Belle rollback? are the developers taking these seriously?
Welcome to the forum! Unfortunately downgrading to Belle is not possible. Any unofficial methods to do this should not be discussed on this forum as it might void the warranty of the device, and possibly damage it. Please refer to the Guidelines.
For the applications please refer to Belle FAQ > Nokia Belle & Applications. Please try to delete and reinstall crashing applications from Nokia Store > My stuff.
