Had some problems with the SD card reader. Removed the SD and resolved the problem.
Can’t seem to get the back two screws in though. Any tips?
I recently had to replace the RAMBO board and I had a hard time getting the two screws closest to the edge of the frame. Not sure if this is similar to the problem you’re having, but I had success by putting double-sided tape on the end of my allen wrench so the screw wouldn’t fall off while getting it into place.
