Finally i did manage to figure out how to upgrade the FW. Locate JP1 on the board and shorten JP1. See attached picture.

Re: MMDVM hs dual not upgrade

I've got the same problem with the same dual hat modem. Failed to init the device. The fw update pins are in place. I've tried it on both pi zero w and 3B+ with the same result. :?
