ExpressLRS Firmware Update Tutorial for SPI Receivers 🎓

Note When you paste back in your old diff into the CLI, it may cause the filters and pid sliders to stop working. As some have pointed out in the video this is what happened on my Happymodel board. It didn't seem to happen on the BETAFPV board. It would be best to not paste back in the whole diff but just the non-filter and pid settings and readjust your filters and pids manually.
