Hi,
I've just bought ASUS RT-AX1800U tried to install OpenWRT 23.05.0. It's failing with Segmentation fault. syslog reports:

Firmware is 3.0.0.4.386 69061. Also tried after default factory settings restored, same result.
Any idea how to fix it?
TIA

Thanks for your quick repsonse. Unfortunately, your right, it doesn't work either.
Post more than the actual error?
The whole flash sequence, if possible.
TFTP flashing is obviously another option, but requires an USB TTL.

There is nothing else than Segmentation fault.

I don't have an USB-TTL adapter, hopefully there is any other chance.

I've downgraded to latest available version 3.0.0.4.386.67508 from here. Same bad result.
znevna was lucky with version 382. So, can anybody provide me this version or an URL to that version?

Not the best idea to use other source than asus.com, but it's for flushing openwrt only. Should I give it try?

Ok, failed as well. Tried with 22.03.3 like znevna but the same bad result.

flash initramfs via the asus restoration tool and after booting into initramfs flash the sysupgrade image using the normal upgrade procedure.

This can only be done when the router is in rescue mode, but it's not working as described here. What is the trick?

See here https://github.com/openwrt/openwrt/pull/11806#issuecomment-1437030658
You only need steps 2-7.
If you didn't manage to fix it yet that is.

Thanks for that hint. However, step 5 wasn't working at all. So I've returned that device back.

weird, the LED wasn't flashing?

There was no difference between booting while pressing the reset butten and without.
