What original Cudy webinterface tells me about the revision:
do you know the kernel version of this cudy build?

For the kernel version I have to look into tomorrow, when I have access to the device again.
Kernel in the Cudy customized firmware:
root@OpenWrt:~# uname -a
Linux OpenWrt 5.4.119 #0 SMP Thu Apr 7 14:23:37 2022 mips GNU/Linux
root@OpenWrt:~# opkg list | grep ^kernel
kernel - 5.4.119-1-1ef2f668119a44ee47519a13132bbbda
And no, even https://github.com/waja/openwrt-cudy-x6-firmware/releases/download/2022.11.28-2204/openwrt-ramips-mt7621-cudy_x6-squashfs-sysupgrade.bin with their DTS file from their developer directory does boot up on my two devices.
The interesting part: their provided DTS file for V1 and V2 differs a lot:

Looks like the V2 DTS looks similar to the openwrt 22.03 one... and indeed:

try to compile with cudy dts and this old mt7621.dtsi
Nope ... didn't worked out ... https://github.com/waja/openwrt-cudy-x6-firmware/commit/26f4c47111366b21621cfa45d73eea766a0fe17c resulted into https://github.com/waja/openwrt-cudy-x6-firmware/commit/26f4c47111366b21621cfa45d73eea766a0fe17c but same result ... reboot loop 
ok now it's a game let's fix that!
can you try:
flash@0 {
compatible = "jedec,spi-nor";
reg = <0>;
spi-max-frequency = <10000000>;
m25p,fast-read;
please try on 22.03.2
Good morning,
still unlucky. I tried https://github.com/waja/openwrt-cudy-x6-firmware/commit/656a454cf5b2f95bca8aab1f8a6175324bea92fd with resulting https://github.com/waja/openwrt-cudy-x6-firmware/releases/tag/2022.11.29-2312.
@waja You'll really need serial here to see any error messages printed at boot. Without, you're going blind.
Actually, I would try to avoid to make adjustments on the hardware, cause I'm still able to return them to the dealer. 
I'm asking me, if it's much better to try to get a V2 somewhere, as Cudy seems to provide a customized OpenWRT firmware which seems based on 22.03. But for this I would like to able to return the V1, if possible.
yes try that check only the u-boot partition if is the same.
Hi,
thanks to the help in https://github.com/openwrt/openwrt/issues/11333#issuecomment-1333530476 I learned, that
https://github.com/openwrt/openwrt/issues/11333#issuecomment-1333871978 is fixing the issue.
