Added a wiki page for ASUS RT-AX52 (https://openwrt.org/toh/asus/rt-ax52) . It’s more of a draft to be honest. I made it just because I had some issues when trying to flash OpenWRT from the stock firmware, there was no wiki page for it and there was at least 1 topic on the forum regarding issues flashing OpenWRT from stock firmware.
If someone has time it can use the info from those links to add or correct the information there:
For sure the installation procedure needs fixing.
I had to use the .trx image provided in Asus RT-AX52 support - #25 by remittor to flash openwrt from stock firmware (it’s initramfs) (openwrt-24.10.2-mediatek-filogic-asus_rt-ax52-initramfs-kernel.bin even renamed to openwrt-24.10.2-mediatek-filogic-asus_rt-ax52-initramfs-kernel.trx didn’t worked, stock firmware was rejecting it), after that i used the normal sysupgrade image.
When I will have a bit more time (job, family, kid that doesn’t want to learn for school and he will have exams that will decide at what highschool he can go to…), I will make some changes.
To be honest I started it so I don’t forget that I want to do this.
L.E. #1: Hopefuly what is now on the wiki page is good enough as a base.
from what i can read you tried to use the wrong factory image. you need to upload “asus_rt-ax52-initramfs.trx” through the vendor ui, wait for the flashing to finish and the router to reboot and then sysupgrade as usual. the “openwrt-24.10.2-mediatek-filogic-asus_rt-ax52-initramfs-kernel.bin” is only used for tftpbooting a temporary image but that requires uart access.
i can definitely say that flashing like this works, as i’ve just done it yesterday with a brand new device.
EDIT: another pitfall i’ve stumbled upon was, that the vendor ui seems to have issues when the filename contains special characters like brackets. just rename the file and it will be happy.
EDIT2: ahhhhh, now i see what the issue is! for 24.10 there is no initramfs.trx being built. thats the issue. you can use the snapshot images for the installation though.
