Crosspost - updating Xiaomi Router 4AC after successful 19.07 flash

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

After several days of bricking, reflashing, downgrading 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:

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?


Have you checked the device page? You can see
details about your hardware in /etc/openwrt_release (also on the overview page in the web interface btw).

Going by the installation instructions you did need to install an older release so I assume you followed these, more or less.
