When removing the cover, be careful: There are a few (two or three?) plastic hooks that break easily in the area around the ports and the SD slot. (It's no big deal if they do break, but you can avoid it.)
I also had trouble with the screw: The (supposed) PH00 from a cheap kit didn’t fit; I also didn’t have a PH000. – But I managed to (carefully and very slowly) remove them with a PH0 (yes, a larger one!), which just barely got a grip on them.
