Can someone guide me through the steps to unbrick my VOXL 1 flight deck using the Expansion V2 board. I could not find the V1 board so I just bought the V2 and now I cant find a tutorial to help me unbrick my VOXL.

I have tried pushing the FASTBOOT button while attaching the Power Cable however the board does not respond. I still can not ADB into the device or do the ```./install``` command in the latest Firmware folder. Any help would be highly appreciated.
Thank You

Does the tutorial still work with "VOXL / VOXL 2 USB Expansion Board with Fastboot v2"? I have a different board I was just wondering if the process is the same because in the video they switch to Fasboot mode with a switch the board I have does not have a switch but a button.

Yes, it is the same. The v1 had a switch in error, it should have been a button. If you see they have to switch back within a few seconds in the tutorial. Instead, just release the button after a few seconds

What do you do if it gets stuck on "[INFO] waiting for device..."?
