Replace iPhone 7 Plus LCD screen on iOS 11?
So I just had a cracked iPhone 7 Plus (the ultra-rare red-back one, which COULD make a difference, I suppose) that was on iOS 11 come in for screen repair. They had tried to get it fixed once but the repair facility said it got stuck on the apple logo and wouldn't boot up. I had just gotten a few different 7 plus screens from different suppliers so I figured I'd give it a shot. With each one, it did the same thing: Apple logo -> flicker -> Apple logo -> my desktop speakers get static-y like a phone is about to turn on -> NOTHING -- it just stays on the Apple logo (the longest I let it sit was about 3 minutes I believe.) With each I had the home button connected to the screen but nothing else.
Now, here's the kicker--I also tried it with a cracked, but functional (to be fair, I do not know if iTouch is still functioning on this screen), original iPhone 7 Plus LCD screen and it still did the same thing. So it's not a matter of aftermarket screens, it appears to an issue with replacing any iPhone 7 screens on ios 11. I know I have successfully replaced screens for an iPhone SE on iOS 11 and it worked. I think I've done a few others but I'm not sure which models.
Has anybody successfully replaced an iPhone 7 or 7 Plus screen when the phone was on iOS 11?
