Get a debian-based linux environment (can be your linux setup, can be a VM, can be an LXC container. I use an debian buster LXC container as my host is arch)
Install required packages
Switch to a non-root account
Clone repo with git
Run ./scripts/feeds update -a and ./scripts/feeds install -a.
Configure it with make menuconfig, this is how 4AGbE looks, pick the packages you want, I recommend setting them to *, not M. M generates them as ipks that you separately need to install (this is what I did to build kmod-ipt-ipset for frosp above). When you're done, hit Save, save as .config.
Start compilation with make.
After a couple hours, the bin file will be in /bin/targets/ramips/mt7621/.
As far as I can see yes, but please keep in mind what I said about having to reset (aka uncheck "keep settings" on luci flash screen) and reconfigure here:
thanks @ave i flashed your image but i don't have access to internet with your build here is serial cosole log:

=====================================
edit: also have same problem with latest snapshot (Wed Apr 15 16:57:41 2020)
Also, @Zorro, did you upgrade from a version before this commit while keeping your settings? If so, you're likely having the same issue I mentioned here, I personally fixed that by resetting and reconfiguring my device (both from inside luci), but there might be a less nuclear path you might be able to take.
172.28.10.* you cant login to luci.
I can't repro this, I personally use 10.69.0.0/24 without issues.
I can´t DM you here, but I´d need that rom, nothing works on R3Gv2, and I can confirm that it´s not working because of the rom since I saw the error through serial:
above image is tested by me on 4a gigabit edition and it worked !!
instruction
before running any configuration scripts==>you need to access the router,to do this,run 0.start_main.bat and enter the password of your router wait for the script to execute. the answer should be like this :
start uploading config file ...
run telnet+ ftpd...
Done
press any key to continue...
the result of the script will be running telnet and ftp servers on the router until it reboots.
2)0.start_read_uboot.bat and 0.start_open_uboot.bat:
shows you the status of the bootdelay and uart_en variables.
0.start_open_uboot.bat==>it changes bootdelay=5 and uart_en=1
this allow you to use the bootloader and using the console in the stock firmware.
and help you to restore the router without a programmer if the OS did not boot
1.start_create_backup.bat - just creates a full backup of the current firmware. As a result of the work, the backup.bin file should appear in the data directory..
4)2.start_write_uboot_R4AGE.bat - THE MOST DANGEROUS SCRIPT to run it is necessary only for the owners of R3Gv2 . Owners of R4GE do not need to do this, you have it exactly the same, and the Chinese have firmware for recovery only for R4AGE. Unlike other flashing scripts, this one does not restart the router automatically.
Replacing the bootloader allows you to restore the router even if there was a jamb in the main firmware, as happened when switching to the 5.4 kernel from openwrt.
The process takes about 7 minutes. the router does not automatically restart, a sign of the end will be change of the yellow LED to blue.
4.start_add_english.bat - the script turns the Chinese UI into English.(Tested on mi4a gigabit on firmware 2.28.62 and it worked)
5.start_write_OS1.bat - a script for changing the main firmware (the bootloader and special zones are not overwritten). The script takes the sysupgrade.bin file in the data directory and flashes it into the router. After the flash, the router will reboot.
@Zorro posted that files and info from 4pda that I found. You can try to use links he provided.
Also, those .bin files does not contain header so if you trying to use builtin recovery they will not work (but that is only my opinion).
I have added the header form r4ag to that dump and modded model to r3gv2. The 28.8 file dump look almost the same as r4ag official miwifi_r4a_firmware_72d65_2.28.62.bin (just short on header and some differences at the end of file). Try to upload this by recovery: http://radek.piastlan.net/openwrt/r3gv2_firmware_72d65_2.28.62.bin
You did anything special to flash the R4AC with firmware 2.18.58. I flashed the Gigabit Edition R4A without issues but the R4AC never seem to come trough. Tried already different openwrt firmwares but none of them seems to work fine. Can't ssh into it, can't get an ip. Had to unbrick it several times already.
I tried with that one and with @Zorro's mir3g v2 firmware version (2.28.8) as well but none of them works...
Thanks for the help anyway, I'll try to contact Xiaomi for an official rom.
to make such firmware you need to have a signature file, and only xiaomi has it. Of course, you can write a script that replaces the public key inside the router, or remove the key check from the flash.
