I replaced my iPhone battery with parts bought of Ifixit and as soon as I plugged my battery in my phone was constantly stuck in a boot loop. I restored the phone completely from iTunes and the phone is still in a boot loop and now it has a load bar at the bottom. Once it loads the phone reboots again.
Update! Went to sell the phone and the owner of the shop figured out that for some reason the ft camera/speaker was causing the boot loop. It was original part from apple. Any reason why
It is possible that the battery is causing this issue but it’s not a typical problem. You could try to put the old battery back to see if that helps or not. However, I’m more concerned about possible collateral damage that may have happened during the repair. Take a look at this guide and retrace your steps to insure you did everything properly. Of particular concern is Step 16. You have to insure that the proper screws are place in the proper holes, otherwise you can damage the logic board. It’s also important not to over tighten them. You should also closely inspect the flexes and connectors to see if they are damaged.
I forgot which screws go where so what should i do
