i was given an old iPhone 4. Need to do a system restore. Can't do it from the phone as I/we don't know the restrictions pass code. Can't do it from the pc as it says I need to turn off find my phone from iCloud. My friend has no idea what the password is to turn that off. The phone has been sitting in a drawer for a couple of years hence the forgotten passwords / codes. I've tried the backupbot process and it says that the backup is password protected so can't even back door the restrictions pass code. Any suggestions?
