Hey guys, I'm hoping you can help me. My mom tried to update her iPad 4 (wifi + gsm, but without a carrier sim card) a few days ago and it didn't work for some reason. It got stuck on the iTunes symbol screen. At first I though it was something minor, like maybe it ran out of battery in the middle of the update. So I helped her download iTunes on her computer (windows) and she tried updating/restoring it but it didn't work. She brought the iPad to me and I've been trying for the past 2 days to make it work (on my mbp). It goes to about 70% of the restoring process but I always get the "unknown error 1" message and it doesn't work. I tried DFU mode, tried downloading the ipsw to my computer, went through the several pages on google trying to find a solution, but I don't know what else to try. Some people online said it was a baseband error, other said -1 is a baseband error but error 1 is usually something jailbreaking/bad downgrading related. My mom's ipad wasn't jailbroken and she was trying to update it, so I don't know. I wanted to set an appointment with the genius bar, but there're only two Apple Stores here in Brazil. The closest to me never has any appointments available and I know just going there and trying to talk to someone won't be any good because they won't see you without an appointment. Does anyone know anything else I can try?
