Chosen Solution
Just finished replacing an iPhone 11 screen. The condition of the phone was fair, front screen was shattered through the screen protector, back screen shattered, phone body bent (it was most likely run over by a car), and the display itself was barely visible, but it responded to touch and voice. I was able to successfully replace the OEM Apple screen with a third party display. After reconnecting the display cables and the battery, I powered on the phone using the side button and it started up as normal with the Apple logo centered on a black screen.
When the phone finally started up and landed on the lock screen, the display said “iPhone is disabled” and quickly faded to black within seconds. The phone then became unresponsive to touch, voice, and none of the side buttons worked to power it back on. I tried to power it on normally, a hard reset, plugging it into the computer and wall adapter, but still no response. (UPDATE: After putting back all screws and securely fitting the screen back onto the iPhone, the phone is responding to touch “Input passcode to use Siri”. I am still unable to see anything)
The only way I am able to get the phone to power back on is if I disconnect the battery cable, reconnect it, and then power the phone back on either by pressing the side button or plugging it into a power source, but even then it only lasts 2 seconds like it did before. I need to be able to back up this phone to move the data onto another, but I need to find a way for the phone to stay on. Has anyone had this problem when repairing an iPhone 11 with an aftermarket screen? How can I get the display to stay on?
An iPhone 11 will display these symptoms if it has a faulty or disconnected ambient light sensor. Try another top flex assembly.
