Phone disassembly¶

The bottom cover plate has 6 philips screws and is clipped together at the bottom. Use multiple guitar picks to get them free.
The plastic does not seem to be brittle (yet), some force is OK.

Backside of the main video / interfacing PCB is visible under the cover plate:

Lift the video / interfacing PCB out by pulling it straight up, it's connected via a rigid interface PCB (but not screwed down):

Unscrew the 7 philips screws attaching the plastic shield. Be careful with the speaker wires on the right, they are not detachable!
Lift the plastic shield out of the way to the right. When re-assembling, make sure the hook-mechanism and speaker are correctly in-place.
