forgot passcode old iphone 6plus
My child is going to use my old iphone 6plus. Apparently there is a 4 digit restriction passcode that I've forgotten which means I can't find the app store to upload a calculator app she want for school. This phone can only go to ios 12.4.8. I'd like to just erase the whole phone, but I can't do anything except use the apps that were there before. I can't make any changes. I'm willing to erase the phone and start over. It doesn't give me the option to reset the password. Is there anyway to do this from another device? Help!
