Just passing here to say thanks to @edeso and to confirm that his method worked for me (2GHz wifi and LAN only). Then upgrading to openwrt-22.03.3-ramips-mt76x8-xiaomi_mi-router-4a-100m-squashfs-sysupgrade.bin did the job :).
Note that it worked with a slightly different layout:

Nothing interesting in my reply. There is an new revision, and it requires 7663, 7615 etc. But there is no stuff at current snapshot (=.targetinfo, target/linux/ramips/image/mt76x8.mk, etc...) bring me error messages:
* opkg_install_cmd: Cannot install package kmod-mt7603.
* opkg_install_cmd: Cannot install package kmod-mt7615e.
* opkg_install_cmd: Cannot install package kmod-mt7663-firmware-ap.
As we can see, current 5.15.141-1 kernel has no this modules, but 5.15.140-1 did.
original post:openwrt-ramips-mt76x8-xiaomi_mi-router-4a-100m-squashfs-sysupgrade.bin got successfully booted OpenWRT. But it without 5GHz wireless interface. Looks like there is some other revision on international R4AC with R4A flash layout.

made successful build at snapshot with this patch (4pda ). dts was taken from BestMC's imagebuilder .
Link looks broken. Can someone post the patch for v2?

There is active PR for this patch. It will be included in upstream if someone could help with review.

I compiled the image about a week ago and my colleague @sergio-gimenez and i have been running it on 10 routers, all of them work perfectly. Thank you very much.
We had different layouts on different routers but the image still worked, here's another layout example:
root@OpenWrt:~# cat /proc/mtd
dev: size erasesize name
mtd0: 00020000 00010000 "bootloader"
mtd1: 00010000 00010000 "config"
mtd2: 00010000 00010000 "factory"
mtd3: 00010000 00010000 "crash"
mtd4: 00010000 00010000 "cfg_bak"
mtd5: 00100000 00010000 "overlay"
mtd6: 00ea0000 00010000 "firmware"
mtd7: 00232d49 00010000 "kernel"
mtd8: 00c6d2b7 00010000 "rootfs"
mtd9: 008e0000 00010000 "rootfs_data"
How can we help to validate the PR? I'm not really familiar with that.

actually, I have no idea how to cast users with review permission)special wiki page :
Fork the project to a public repo using GitHub web interface, clone the repo to your computer, create a branch for your changes, push these back to GitHub and submit a pull request.
So I have no an idea is there any other mechanisms to speedup this pull request)

I used this steps; You can clone repo with PR and checkout to billic:xiaomi-r4ac-100m-intl-v2 branch. Then you can follow main instruction and build own image)

It was forked from main repo on late 2023. There was 23.05.02 . 23.05.4 was released in july but my PR seensPull Request I made into main repo from my fork. But it stil on review after eight months and I have no ability to speedup accep code to main repo. Only 2 of 6 required reviewers made an action. Looks like OpenWRT developers has no ability to review all incoming code.

Sounds strange... I see definition of eeprom_factory_8000 at mt7628an_xiaomi_mi-router-4.dtsi file whick included at 3rd line.
Can you build firmware with ...100m-intl.dts file? What about mt7621_xiaomi_mi-router-4a-gigabit-v2.dts which has same MT7613?

I tried with 23.05.4. Since mt7621_xiaomi_mi-router-4a-gigabit-v2.dts is officially supported, there is no problem. but I can't compile intl-v2.dts
