Hi,
How should I define what to put in board.d? I see some board are using eth0 and some are using wan. Thanks
You can get away with so called "breadboard wires" without soldering.
I use that and it works like a charm
But I still have to create the openwrt files 
(dts and so on)
In order to connect without opening the case the user would need longer pins like this guy did for the ax53u: OpenWrt support for Asus RT-AX53U - #43 by nemoforum
Hello, I was able to boot in openwrt via an initramfs. What test should I do to know if everything works? Normally AX52 doesnât support 160MHz but the openwrt UI was showing the 160MHz setting but when trying to use this setting it doesnât work.

NOT TESTED !!!
Is there anybody who has the right to rebase the PR as it was requested? all the review comments are accepted. it would be a waste of time to clone the PR.
It didn't work for me.
- Brand new RT-AX52, accepted licesnes, created admin account
- navigated to it http://www.asusrouter.com/Advanced_FirmwareUpgrade_Content.asp
- uploaded TRX image
- Actual result: Firmware update unsuccessful
Any ideas or should I just return router?
AX52pro not supported
Hi everyone! I'm trying to install OpenWRT for my Asus RT-AX52
- Firmware version: 3.0.0.4.388_34015
I've been following this guide (https://openwrt.org/toh/asus/rt-ax52#asus_rt-ax52) using the Vendor UI Method. I was able to do it until "Upload the .trx file to router". Although I can't access the Luci interface to flash the asus_rt-ax52-squashfs-sysupgrade.bin. It will say that the site can't be reached and I could only access the Asus Wifi UI (192.168.50.1).
Some observation whenever I flash the .trx file the firmware version of the Firmware Version doesn't change in the Asus Interface.
I tried downgrading the firmware by getting it on the Asus site but it also doesn't change the firmware version.
Use the GDrive TRX image from four posts up, as 1st step, then flash the vanilla sysupgrade.
Forgot to mention I also tried that .trx file but firmware version is still the same and can't access Luci.
Unless @remittor knows what the issue might be, you'll have to use serial to flash it.
Check if there's a recovery tool from Asus available, it should let you downgrade, since it's bypassing those checks.
There is ASUS Firmware Restoration Tool support in the Asus website.
I also suspect the same thing, since I can't downgrade the firmware using the Asus Web UI even using the old official versions from Asus. Then after some digging I found that some Asus Routers use "ASUS Firmware Restoration Tool" (https://openwrt.org/toh/asus/rt-ac51u) to flash the OpenWRT firmware.
Although I wanted to ask here first since it wasn't part of the official documentation and this is my 2nd time installing OpenWRT. Do you think I should first downgrade the firmware of my router using the Asus Firmware restoration tool then attempt to the steps in the guide or can I flash the .trx file (from the Google drive) using the Asus tool?
I'd try to downgrade the firmware to the oldest one you can find, then try the openwrt initramfs, if it doesn't work, the one from GDrive, as a last step, you could try flashing openwrt directly using the recovery tool.
Alright! I'll do it a little bit later then update here. Thank you so much for the responses Frollic!
I figured to write a mini guide on how to do it for people in the future and hopefully to update the guide here.
