This is being called “Loop Disease”, and it is related to the Audio ic or the Baseband PMU. The solder joints beneath these IC’s are in a weak spot and will actually crack and/or separate from the board. Once this disconnects, the device cannot receive the data it needs upon boot up to actually boot fully. We have been repairing this issues like crazy at my shop here in the St. Louis area.
