Others have reported that their iPhones have become stuck at the Apple logo following a recent repair, such as a screen replacement. If the four screws holding the plate over the screen connections are replaced or not correctly fastened, this is likely to happen. When a screw is put incorrectly (for example, when a long screw is pushed into a short screw hole or vice versa), the logic board of the iPhone can be damaged, resulting in a boot loop and/or blue screen. Unfortunately, a DFU restoration will not be able to resolve this issue. or can even make the problem worst. This however should not be the case on your end, considering what have is a new iPhone.
