I have had iPhones since they were 1st introduced so no one can blame this huge problem on my being a clueless newbie. Out of the blue one day when I went to make a settings change I was asked for this code. I have every security question, password, emergency email address that I have ever used stored so that I can refer to my list in the event of a lapse in my memory. I KNOW there are only a handful of codes that I would have used so I didn't ever set it. I did a complete restore from backup and was so mad when I completed the restore only to have the darn thing ask me, for the 8th time, for this unknown restrictions pass code that I NEVER set up. Decided to just bite the bullet and do a complete restore back to factory defaults which took WAY over 24 hours!! I never thought about the fact that my workhorse old iPhone 4 would have to go through 2 years of updates in order for me to use the apps on my phone. I have a LOT of apps!!! I about went postal when my freshly restored phone asked me again for the code. I went to the store where I bought the phone to see if they could help me and the sales person took a look at my old phone and said it was about time for a new one anyway. I was told it was likely just an incompatibility thing since they were really only writing updates as far back as the 4s and a brand new phone would solve the problem ---- WRONG!!!!!!! It still asks. Someone help.... I have had 8 failed attempts. SURELY Apple support can figure out how to reset this thing. I know all the answers to my security questions, I have the emergency backup email in place, I use 2 step verification...... for goodness sake SOMEONE find a solution --- please help me!!!
