Huawei Honor 7x Disassembly

First, loosen the two screws on the left and right of the USB port (P2 bit).

Carefully pry the smartphone cover upward bit by bit, starting from the USB side.

Caution: Especially if the display is damaged in the corner, two gaps are visible (red arrows). You should use the lower one, as otherwise you’ll pry out the display and won’t be able to proceed further.

After opening, the smartphone looks like the first image. Now, the ribbon cable for the fingerprint sensor needs to be disconnected to separate the two halves.

You can either disconnect it on the cover side (second image) by lifting the gray plastic piece with a small screwdriver, or remove it on the "circuit board side" if you’re already planning to replace the battery or display (next step).

To disconnect the cables, remove the Phillips screws and pry out the cover plates. At the points marked with an arrow, the plates are additionally clamped beyond the screws.
