After battery replacement with iFixIt battery, phone will not turn on.
About 10 months ago, I ordered a replacement battery from iFixit. It stayed in my drawer for a while and now the time has come to swap it in. I did this once before, and I had no problem. However, this time around, after I put everything back together, the phone screen is not working.
The phone vibrates when it is first plugged in, and my computer recognizes the iPhone. However, the screen is not turned on at all, including the back light. I opened it up again and double checked that every single connecter was connected and plugged in. What could be the problem?
Is this a good question?
