I’m trying to delete all content and settings on my iPhone. During that process, I have to enter my Restrictions passcode. I have no idea what it is. I already tried 8 times.
Does anyone know how to get around this? This basically means that I’m unable to factory restore this iPhone and pass it on to someone else.
Does it not wipe everything after 10 attempts anyway?
hmmm i don’t know actually. Isn’t that just passcode-related? I believe there is a setting somewhere that sets the iPhone to automatically wipe after 10 failed passcode attempts, but I don’t think there is one for a failed Restrictions passcode, or maybe I’m wrong
Ah! Potentially, sorry.
Although any harm in trying?
