Frequently Asked Questions

Does this main flex fit the standard Huawei P40 or P40 Pro+?
No, this flex was designed specifically for the Huawei P40 Pro chassis, having dimensions and connector layouts different from the other models in the range.

Does replacing this cable solve charging port issues?
Only if the fault is a break in current transmission between the lower board and the motherboard; if the USB-C connector is physically damaged on the sub-board, the part to replace is the charging board.
