Asus TUF AX4200 support

You don't without dumping it, if you never updated it and depending on when you bought it, you might be okay.

I was on the latest Asus firmware back in October and didn't have the latest uboot at the time.

With that said the fix was merged a few weeks ago so the latest snapshot builds should have the fix.

I did an automatic update on mine recently so it's probably on the latest November software, but it does have an option to revert back to the previous version. I will revert back and install 24.10.0 and if it bootloops I'll use a build from https://github.com/openwrt-xiaomi/builder/releases.

hello everyone, i cannot configure sqm for my asus connected in pppoe mode. I am attaching my settings because after a day of trying I give up, either there is a bug or I'm doing something wrong anyway it doesn't seem to be working. Thanks for anyone who wants to help me. My openwrt -> Powered by LuCI openwrt-23.05 branch (git-25.053.28810-8216ff5) / OpenWrt 23.05.5 (r24106-10cc5fcd00)







You should not need to build yourself, the fixes have been merged in snapshot.

Guys, please help me. I probably did something wrong. I connected the LAN cable from the main router (which is provided by my provider) to this ASUS router in the WAN port, and connected the LAN cable from the ASUS router to my computer.

In the stock firmware, I installed the openwrt-24_tuf-ax4200-initramfs.bin file from the remittor's google drive via the web interface.

Next, I logged into the LuCI web interface via 192.168.1.1 and downloaded the openwrt-24.10.0-mediatek-filogic-asus_tuf-ax4200-squashfs-sysupgrade.bin file. I waited for 20 minutes, and then I reloaded the page in the web interface and now I can't log in to it. There is no cable connection and I don't understand what to do. Please help me.

P.S. My OS is Windows 11

Guess you may have encountered this issue:

Please note that OpenWrt 24.10.0 works only on devices with U-Boot 2022.04-rc1.

If you have a recent U-Boot >= 2022.10 installing OpenWrt 24.10.0 will brick your device.

If unsure DO NOT INSTALL OpenWrt 24.10.0 and wait for OpenWrt 24.10.1.
https://openwrt.org/toh/asus/tuf-ax4200#supported_versions

you should be able to restore stock firmware with the instruction in first post:

after that, if you want to use openwrt, you must wait for 24.10.1 or use snapshot.

You're probably right, I read this message too late because I was flashing according to the instructions from the video, and the author put version 23.05 in it... Thank you!

I have an AX4200 on the way, I'll have to check U-boot version, but I am looking forward to trying the .trx install instead of accessing the serial port.
I picked this as I'm looking to diversify my networking ecosystem LTS support, and have had good experiences with ASUS routers in the past. The AX6000 has the same guts but it's additional Wi-Fi chains requires a larger physical footprint and neither has 6ghz so this was the winner.

Hi,

I see Remittors GDrive have a new trx image dated March 31, 2025. Does anyone know if this has the fix for the u-boot issue?

Thanks

That's a good question, nothing is clear. I've asked on the AX59U thread as well: OpenWrt support for Asus RT-AX59U - #85 by KrypteX

I did risk it and test the AX6000 version on my AX6000 with the latest Asus firmware and it worked perfectly no boot loops. I was then able to upgrade to 24.10.0 with no issues.

Thanks Remittor!!!

@qhplar remittor just updated the trx files about half an hour ago on his Google Drive. Not sure which one did you use: from March 31 or from today April 4?

@KrypteX I used the March 31 trx file and had no issues. I wonder what the difference is with today's updated file?

Only @remittor can answer that.

  1. update facinstall (preinstalled pkg into initramfs image)
  2. auto enable WiFi on boot initramfs

@remittor Which version of the TRX is preferred for first install (factory-to-openwrt)?
openwrt-23_rt-ax59u-initramfs.trx from Aug 6 2024
openwrt-24_rt-ax59u-initramfs.trx from Apr 4 2025

It seems to me that 23.x never had the bootloop issue with newer U-Boot versions i.e. 2022.10, it was only 24.10.0 and snapshots up to Feb 15 or so that had the issue.

I was thinking to first flash the 23 TRX, then sysupgrade to latest snapshot... Or is 24 TRX and then latest snapshot a better idea? I'd appreciate more input on this, if possible. I'm not sure I understand very well what happened with the partitions when the bootloop occured on newer U-Boot versions. Thanks!

You rigth choose:

  1. latest offiacial snapshot
  2. my builds of OpenWrt 24.10.0

What about the trx versions? That was my primary question...

Any version. But v24 included fixed facinstall.

What build are your TRX files based on? Is it this repo https://github.com/openwrt-xiaomi/openwrt or the official openwrt main branch (snapshot)?

Your repo hasn't been synced with the official openwrt since Feb 4, which is before @daniel's u-boot fixes from Feb 15

So I assume your repo doesn't include these fixes?
