Apple Event: May 7th at 7 am PT
Yesterday I changed the screen and battery on an iPhone 7. When I finished and restarted the phone it would not boot up. It just cycles between a black screen and the apple logo. I have tried everything that I can think of to get it up and running but nothing has worked. This includes: force restart, update in recovery mode, restore in recovery mode, restore in DFU mode, leaving it on charge several hours. Does anybody have any suggestions?
Thanks,
iPhone 7, iOS 10.3.3
iPhone 7 is too young to need a battery change --what made you change the battery?
Apple logo -black screen sounds like either the battery is not connected well, or its a bad battery, software corruption, or the Tristar chip was the underlying fault all along.
I would eliminate variables--attempt to restore with native battery and no screen attached. See if it passes restore.
Give us some more details about what your thinking was here so we can help you.

It is a total mystery why you would attempt a self-repair on a phone that was still covered under the 1 year warranty. Even if it needed a screen, Apple will replace it for a reasonable price. Yes, more than you can replace it for yourself, but why take any chance at all with a phone that costs close to $1,000?
To answer your question, the reason I was changing the battery is because the one in the phone would not hold a charge and I was being paid to change it along with the shattered screen. The fact he did not have insurance on the phone and the closest Apple Store is a 3 1/2 hour drive probably had something to do with him bringing it to me. Granted I'm just an old dumb redneck from a little country town in south Alabama but I get quite a bit of buisness.
Just in case you are interested, the Boot Loop issue has been figured out. A friend of mine in NYC recently encountered the same problem after replacing a iPhone 7 screen and told me it is caused by a faulty front facing camera. Sure enough, after disconnecting the camera the phone booted up without any issues. I happened to have a spare camera on hand so everything worked out and I got paid.
Thanks for the feedback. It ended up being caused by a faulty front facing camera. I never would have figured that. Good news is had an extra camera on hand and the phone is now back with the farmer I was fixing it for and will be doing laps in a tractor by morning.
Glad you got it figured out--eliminating variables is always a good troubleshooting step. I would watch that phone though and make sure that your battery replacement solved his underlying concern--a 7 really is too young to need a new battery and the native battery is generally superior to aftermarket batteries. If he continues to have poor battery performance consider software drain or bad Tristar is he uses a non-MFI certified charger, especially in a car....or tractor!
Stuck in boot loop, help!
