Hi Guys. So I have an iPhone 6, and I had an iPhone 4 before that. I had set a restrictions passcode on my iPhone 4 and then forgot it. I restored the same back up on my 6 as well. So the restrictions passcode has been followed onto this one as well. I have a lot of important stuff on my iPhone and dont wanna lose data. How do I find out my passcode. I looked up this thing called iphonebackupextractor, but am not sure about it. Really need to get my restrictions passcode back, cause I don't have facetime on my 6, and it might be "turned off" in my "restrictions". Please Help! My phone is currently on the 8.4.1 IOS.
