OpenWrt stable 19.07.2 firmware for Xiaomi Mi Router 4A Gigabit version

I followed instructions shared in [1] and successfully let the device operate. I deployed snapshot build at beginning, but sadly I ran into a bug[2]. Obviously, stable version is the better choice. I put the mir3g-v2 description file back to the stable branch[3] and built with luci web interface. The built firmware could be downloaded here[4].

Update: There’s an open-source tool [5] to get the root shell from the device without hijacking the chips. Please leave a comment if you need video guideline.
