UPDATE!! I missed the part where it said to create a folder called "elrs" to drop the files into. All good now!

Watching Ryan Quellet's video on setting up head tracking on my BOXPRO+ and for the life of me I cant figure out why I keep getting a FAILED message when trying to update the ESP32 backpack. I have tried multiple sub 32gb quality FAT32 formatted cards. I generated my ESP32 backpack update via ELRS configurator and have even tried previous versions AND the goggle firmware for giggles too. All immediately fail. I have no issues updating the general firmware. As much as I'd prefer to be wireless I'm about to give up and just use the trainer port and cable. Any ideas on what may be going on?

Thought this might help some folks like me. I love the Freestyle v2 kit but hate the mounting method of the Nano 90, especially in my Volador 3.5. I came up with this 14mm to 20mm adapter. Its a bit of a pain cause it requires m2 brass threaded inserts (specific item in the thingiverse link) but it holds angle much better using 2 screws rather than the one. The screws are spaced 6mm which seems to be a DJI standard. Just be sure to use appropriate length screws on everything and you should be ready to rip.
