I have replaced the rear camera and the power/flash flex and now I can’t reset up the phone (I backed it up to older phone) and it turns off every couple minutes on a loop. Did I do something wrong? Everything looked good and attached properly as far as I could tell. Thanks

Did you use an aftermarket port or did you buy a premium (OEM) port? If it’s anything like the charge port in these phones, you might need to go with an OEM or premium port. The X and above are picky when it comes to charge ports. If you use aftermarket they will boot loop.
