MCG Pro not recognized in bootloader

[dukethejuke]

Received my new MCG Pro, downloaded all files as Youtube video showed. Of course bootloader only showed my old gunfighter WW2. How to get to recognize. Thank you for your time. Duke.

If you have a Black Box MKII you could try flashing the MKII Unified firmware. When swapping grips you won't need to the reflash anymore, just reset to default, click Yes when the config popup shows up and recalibrate.
