Cherry picking alone wont work. There were a lot of changes with syntax during the past months. I've tried to manually inspect and merge changes while I get no compilation errors, I'm unable to boot the device so I had to resort to Win PXE to reflash stock ROM. Hopefully those who were able to compile upload their repo for us to compile too.

It turns out I think we have been geo-blocked! I had to use a Chinese proxy to download the stock firmware for the 4A 100M and I've re-uploaded it here:

Hello,
I have telnet access thanks to this video: https://www.youtube.com/watch?v=VxzEvdDWU_s
The problems is that I can not download the openwrt firmware from anonfile, someone could upload to an other repository?
Thanks for your help.

Hello,
I installed this firmware: https://github.com/acecilia/OpenWRTInvasion/tree/master/firmwares/OpenWrt
The problem is that it has no LuCI, and when I try to install I have this:
# opkg install luci
Installing luci (git-20.145.56006-f6f4005) to root...
Downloading http://downloads.openwrt.org/snapshots/packages/mipsel_24kc/luci/luci_git-20.145.56006-f6f4005_all.ipk
Collected errors:
* satisfy_dependencies_for: Cannot satisfy the following dependencies for luci:
* kernel (= 5.4.42-1-dbf4f203d2a50343b47363720878f043)
* opkg_install_cmd: Cannot install package luci.
Is there any other OpenWRT image with LuCI?
Best regards.

MIR4A arrived today 
- hence my first post as this device is not supported for such a long time yet and I don't want to brick it on first flash...
@Zorro/galotzas Can I just build my own image using imagebuilder from here: https://downloads.openwrt.org/releases/19.07.3/targets/ramips/mt7621/ to reproduce this image?
Did you make any adjustments?
THX 2 @Zorro !
- Sysupgrade from 19.07.2 to 19.07.3 is flawless. Main Settings remain as is. Theme is changed back to Bootstrap should you use another one but re-download it and thats it.
- IPerf3' #ing:
[ ID][Role] Interval Transfer Bitrate
[ 5][RX-S] 0.00-30.04 sec 1.16 GBytes 332 Mbits/sec receiver
[ 8][TX-S] 0.00-30.04 sec 153 MBytes 42.6 Mbits/sec sender
looks similar to here.

Hi i have the chinese version (not the global) of the mi 4A gigabit edition.
I have problems to flash the zip files, ive tried https://anonfile.com/D7Y5V21fo9/mir3g-v2_owrt_19.07.3_zip several times,
curl command (i have directly renamed it to "firmware.bin")is ok and its downloaded to /tmp directory, then i do: "mtd -e OS1 -r write firmware.bin OS1" but then it always end in a bricked box (orange led flashing for about 30min)
use this instead.
