Update: wondering if it's a heat inspired reset. I had the phone off all night and turned it on this morning and it's been on and used almost an hour with no resets yet. Hopeful but expecting it to reset when it heats back up. We shall see...
Whoa...by far the most stress Apple related repair I've attempted. Sadly I have to say attempted. RIght out of the gate, I felt I was being so very careful, gently applying pressure to lift the glass to expose the touch sensor cable when the glass just released suddenly and the clip flew & the cable detached. *gulp*. I figured all was already lost but might as well proceed as if it went smoothly. Everything else did, especially removing the adhesive. Not an iota of trouble there. I was excruciatingly careful with the screws to make sure they were not mixed up. The reassembly seemed to go smoothly but upon powering it back on I had the white lines and resetting after a couple minutes. I took it back down a couple of more times to get to a clean display that functioned as it should and apart from the resetting every few minutes with a blue screen, all other functionality is intact. It sounds like long screw damage but they were not mixed up at all. Puzzled and bummed. So close...so close. Tightened too much??
