After I installed a new battery from ifixit.com to fix the error 29 during a firmware update (which worked perfectly fine with the new battery), my phone just randomly turns off and without a charger I can rarely restart it. At first, even my time was set back to the first of January in 1969 every time this happend but when i set it to “set automatically” it seemed to have fixed this part of the problem. Just FYI i also had to update my baseband to the ipad version 06.15, because I was forced to restore with an original firmware and really need an unlock. I hope you can help me!
That might be a result of the iPad baseband. Using the iPad baseband has all kinds of nasty side-effects that aren’t mentioned on the dev team’s website. All I can think of would be to restore from DFU mode, and hope that works.
