A quick search (including the link to the wireless wiki) shows that the chip is connected via the SDIO bus. Since the dmesg output doesn’t show anything mt76* relevant, this suggests that the communication over the bus is not functional (i.e. the chip isn’t even detected on the SDIO bus). (I had a similar problem with the WiFi/BT chip on my Ugoos AM6 plus, you can search the forums for info relating that.) That’s the help I can offer.
