3. Detach the Ribbon Flex Cable(s)

Depending on if you have an option board fitted there will be either one or two ribbon flex cables. You can detach them by very carefully sliding a flat-blade screwdriver under their retaining latch. They should pop up instantly and release the ribbon flex cable. I they do not, do not force them, rethink and reassess.
