is there wan port outside switch? Check that with miitool too, 99% it is same phy
now plug cable in each port to find disconnected one - that has to be disabled in dts (rt-ax54 vs rt-ax53u)
then go to /sys/class/leds and write 0 and 255 to each to check they are mapped correctly.
somebody smarter may know what strange port status means, here they look working.
I've managed to build it with it's own dts, Lan and wifi is working normally, but not the "LED", it a rgb led on this model. I'll do some more testing before submitting it. If anyone want this preliminary image just send me a message.
This is the git diff i got working if anyone is interested:

@brada4 Thanks a lot for the guidance.

You have to check if disable-radar-background is needed.
It is the cool immediate switch to new dfs channel on radar event like in openwrt one
I'm trying to log to the stock console but with no success. I found a md5crypt hash on a passwd.bak file on the stock firmware dump,
admin:$1$$7Kp2mziTqAoI6OQuI0gZf1:0:0:root:/:/bin/sh
dropbear:x:500:500:dropbear:/var/tmp/dropbear:/bin/sh
nobody:*:0:0:nobody:/:/bin/sh
So, if I can crack $1$$7Kp2mziTqAoI6OQuI0gZf1 I will be able to gather better information on the device.
Leave the hope it has top gpu secretly bolted on aside 
Dump and binwalk their partitions.
I've sorted out the LEDs gpios. I'll leave the latest build I have running for some time to test it.
If @BGS_Admin want, I can share my build for testing.
