Sadly this is the first I have heard or seen of this driver. I did tell him to put his name on the driver which was supposed to be coming down the line but they’re also supposed to be red and I don’t think they have the fuse values set correctly yet. Any driver that has all the corrections I sent Simon has not even left the factory yet.
Like Jerommel said, the flashing issue is likely a grounded pin on the MCU. That is the case on the red drivers. Tom E did some troubleshooting for me and in the case of the red drivers pin #5 of the MCU was grounded and to flash the driver he took an exacto across the trace that was grounding it, then it flashed fine. I can’t see close enough from these pictures but in the case of the red drivers you have to cut where the yellow lines are shown below to break the connection and then it flashes fine.
