I have an iPad Air 2 jailbroken on 8.1.2 which was working great up until this morning when all of a sudden it stopped recognizing my 4 digit passcode. I'm still dumbfounded that something like this could happen. I have the same passcode on both my iPhone 6 and my iPad and the code is working normally on the iPhone. Needless to say I don't want to lose my jailbreak so I'm trying to avoid a restore but I don't know how else to fix this. I've tried Semi-Restore but it asks for the passcode in order to work so that's out. I've also heard about a passcode breaking utility called Elcomsoft iOS Forensic tool but it's almost $1,500. I don't know what else to try. I'd appreciate any help.
