Notes

- Display cover got diffuse after cleaning:
    -> Non-original part
    -> Cleaned old glue
    -> Attached new replica part
- LCD has deep scratch in the top half
    -> Maybe fixable by replacing polarization filter
- LCD has two adjacent rows near the middle that are much brighter than the others:
    -> TODO: Not tried to fix yet
- Link port cover was missing:
    -> Attached replica part
