So here is my problem: I wanted to update my iPad to iOS 6 but it makes error. Then I knew it was from the jailbreak, so I tried to format it from settings, but first it just freezed, then I turn it off then on again then I tried again, same freeze BUT THIS TIME, when I restarted my iPad and slide to unlock, it turned to safe mode. I respringed a lot of times but, same error. So I use safe mode at the moment but I can't use almost all tweaks or just cant modify any. So I know the answer will come with a PC but, I don't have PC at the moment and I remember that this happens in 5.1 and I was having PC but somehow I don't remember I fixed it without PC so please help. Edit: Uninstalling tweaks and hacks makes no use.
