Scuf unfortunately use a unique security screw as far as I am aware I had to use a combination of careful wedging and a little brute force with the U shape driver bits it takes some work but it is possible to get out. the head of the screw itself is a star shape so most probably a wrench type driver bit if any hope this helps
hi @bkdan what I have found is you need to ensure that the lens is attached to the camera correctly. This error message will appear if the lens is not attached correctly to the camera or if you are not using a CPU lens Alternatively, if the lens has an aperture ring, it may not be set to f22 (or the highest aperture number on the aperture ring - normally marked in orange). Select the aperture number marked in orange on the lens and lock it using the aperture locking switch to prevent this occurring again. Set to F22, or the highest aperture number normally marked in orange. Note the locking switch. If the above did not resolve the problem and you still experience the error display FEE, in this case, you may need to return your equipment for service. Before doing so please also check the following. Check that the EE servo coupling highlighted on the lens has not been broken. Check that the F-min switch highlighted on the camera body has not been broken.
it sounds like it may have been dropped during transit if not even with the ram flopping about inside during transit could have done damage to the motherboard or other components I would look at testing the chips and other components in there to make sure they are all connected I would also get on to the person who sent it and even the company who delivered it they maybe able to tell you what happened during transit to give you an idea of if it was a transit drop or a seller fault hope this helps
