ASUS RT-AX1800S V2 Installation Help

Hello,

I am seeking any assistance or information with installing OpenWRT on the ASUS RT-AX1800S (V2).

I follow the steps listed here: https://openwrt.org/toh/asus/rt-ax54

I have tried different variations of the install via tips found on these forums and others all ending in the same failure.

The failure is a Segmentation fault error using the mtd-write command. For example:

I am also attaching a few screenshots for further information.

Is this a V2 hardware issue? I've seen few posts that lead me to believe this is the case, but there isn't much information given on this possibility.

Thank you in advance for any information anyone can provide and let me know if I need to provide more info here.


Whats in uname -a?

It is different device.

Thank you very much for the help.

This was it exactly.

After downloading both the files mentioned in the linked post, I have OpenWRT up and running on 2 devices now. Thanks again!
