anyone know what that is?
error code: -1
supposed to be a hardware error, but my iPhone sometimes gets this issue when trying to downgrade using the shift+click or option+click way. my iPhone works fine.
Assume you got it from trying to restore your phone.
To fix it,
1. Re download the ipsw (it solved my -1 problem last time)
2. You might wanna call apple, it could be hardware.
