Hello! My iPhone 7 is stuck in a boot loop. I have tried just about everything. I started by trying to replace the FPC connector for the charging port. After changing that the phone was still stuck in the boot loop. Then I tried to replace all the parts with genuine Apple parts including the Front Camera flex, the battery, and the charging port flex. I know it is not the Audio ic because the phone doesn’t stay on the apple logo for more than 10 seconds. Any ideas? Any help would be amazing!! Thank you so much!
Try booting your phone with just the LCD connector and battery attached. If it is still boot looping you may have to put it in DFU mode and do a restore through iTunes. If iTunes brings up an error let us know what it is.
