WARNING: many screws on XF605 are secured using threadlocker.
Double check that you are always using a perfectly fitting screwdriver and alway apply sufficient axial force when (un-)screwing, otherwise the screw heads are very(!) easily damaged beyond repair.
As always: never use force for separating things. Not a single plastic clip has been encountered on XF605 so far...
If something doesn't come off very easily, you very very likely missed either at least one screw, connector with extremely thin wires on it or a very delicate flexible flat cable!
