I ordered a Xiaomi Mi Router 4A 100M and got a Mi Router 4AC 100M (NOT gigabit) .

After several days of bricking, reflashing, down grading the firmware, installing virtual box and ubuntu and following @hoddy tutorials, I finally got to telnet into it and installed this version ( @zorro I think):
OpenWrt 19.07.2 r10947-65030d81f3 / LuCI openwrt-19.07 branch git-20.057.55219-13dd17f

Now it seems to work fine --I can use the luci interface to make changes see stats etc.

I could not find an answer in the 1000 message long forum post on the 4A/gigabit. And I spent a lot of time trying. And learning a vast amount.

I see there is a version 21.02.02 available for the Mi Router 4A (not 4AC) on the openwrt downloads page:
https://downloads.openwrt.org/releases/21.02.2/targets/ramips/mt76x8/openwrt-21.02.2-ramips-mt76x8-xiaomi_mi-router-4a-100m-squashfs-sysupgrade.bin

will that work on my Mi R4AC 100M? I am assuming so because it has the same "mt76x8"

If it will work, should I update via Luci or should I still use openwrtInvasion and Telnet/Curl to install the update?

Thanks

fyi, the photo of the rear of the R4A in the wiki page actually quotes ' Mi Router 4A ', model: R4 AC

Based on these and @Boromini over in developers, I held my breathe and upgraded to the latest xiaomi mi4a 21.02.2 sysupgrade.bin. And voila - it worked.

Thanks
