Invalid Firmware Upload ASUS AX53U

Do I have to convert the .bin file to .trx format?

No idea, if you solved the problem already.

I created a few posts re AX53U already. Search for it.

Generally it didn't work for me, without registering the device at Asus and updating to the newest Asus firmware. Then it was pretty easy as described at the openwrt device page.

But now I cannot access the device after updating from 23.05.2 to 23.05.3. I create an own thread for this problem.

Edit; Found this in the meantime:

Flashing an original Asus RT-AX53U using scp?

Not necessary, it worked to connect the Asus WAN-port with an Ethernet-port of an Archer C7, which is wireless wds-client. I did not get it work to configure ssh with the original-FW without Internet. But the connection above did the job, including an Asus-FW-Update to 3.0.0.4.386 But then you have to know some things which is different to the wiki. After enabling ssh you have to reboot the rooter. I tried a lot ssh connections and was blocked at the end. You have to define a router account…
