Hey guys, I have just replaced proximity/front facing camera flex but not phone does not go further then apple logo. But if I disconnect proximity/front facing camera flex it boots just fine. I have tried home+power but the problem remains. Is it bad proximity/front facing camera flex?

Try a new from camera cable and see if that works. These are often defective and can be damaged easily. Was this the original one or a replacement?

Possibly is a bad prox but try to plug in the prox while the device is powered on as well.

dissconect the front cam and power on the phone if it boots in system try another front cam
