Okay so i have and ipad 3 jailbroken 6.1 on redsn0w unthetherd and i was on safari and out of no where it turns off.it wasnt low battery it was on 50% and i didnt install a package only and i will explain to you how it looks like when i boot it
it boots with the apple logo in full brightness and then it dims aittle and then it looks like it shut of for a while then its comes back up with a low brightness and just stays like that, nothing else happens.whats wierd is that this doesnt happen to other people.ive searched up on how to fix this.ive tried the one with holding the volume button dont work either.and whats also weird is that my ipad you can turn it off and itunes recognizes it.so i still think that i can boot it back up without restoring it. Ive also tried booting it with redsn0w by booting thetherd only but then in the middle of the process it says unexpected error, is there any other way to fix this
