Troubleshooting issues with iOS 11 and 3rd party hardwareI've been having trouble getting my iPhone 7 Plus working with iOS 11. The following hardware items have been replaced...
Answer to "After update to iOS 11 Touchscreen unresponsive"So far, the only solution I have been able to find is to downgrade to iOS 10.3.3. You have to act quickly as Apple will not be signing the 10.3.3 download much longer. If you have a Mac or PC running the latest version of iTunes, you can force it to install iOS 10 on your iPhone. You can find the iOS 10 download here... http://osxdaily.com/2017/07/19/ios-10-3-3-download-update-ipsw/ I was able to get my iPhone 7plus working again by downgrading. What a waste of a Saturday morning :( Now I've gotta go to the Apple Store and beg them to take my money for a OEM screen. ~Chris
