Excellent guide. This helped so much for me to replace my failed flight control board. I dropped one of the small screws and could not find it! I bought a DJI Phantom 4 fastener pack that has alot of these specialty screws. I only needed one screw, but now have lots of backups for future. An improvement to the instructions would be reassembly steps. It could help with some of the wire routing that I figured out the routing, but callouts would help. As a contribution to a possible update, I figured out a simple, reliable technique to push the dampener boots through the flight control board corners. Essentially use needle-nose pliers to squeeze the wide part of the dampener and push one end of the squished profile through the board hole. Use your other hand to pinch or roll the rest of the dampener through the hole. If allowed here is a link to a video showing how I did this: https://youtu.be/QHvy0n_iorE
