Made a initramfs version, added LuCI (an old song) in it - then flash from http://192.168.1.1 should be straightforward.
Edit: problem with wikisend ... the part below is likely not working
The file is on "wikisend"

The doc is updated (wait 1~2 seconds after plugging USB or you may miss the tftp window [doc said 2-3])
- install a tftp server on your pc (debian: "apt-get install tftpd-hpa")
- copy the file in your tftp server directory (debian: /var/lib/tftpboot/ )
- rename it "firmware_WMR-300.ram" and ensure it's readable by everyone (chmod 644 file)
- connect the NIC of the PC to the router one, PC IPv4 is 192.168.11.168 / 24 (note the .11., not .1.) (then restart NIC, debian: ifdown ethX ; ifup ethX)
- plug USB to router, after 1~2 seconds press AOSS for ~5 seconds. Release and wait.
Nothing should "move" - LEDs are stuck, ON.
So, I'd advise you to set a verbose mode for your tftp server.
These are my options on Ubuntu (debian)
TFTP_OPTIONS="-4 -v --secure --create"
Note the "-v" for verbose.
So you can
to see when/if the router requests the file, like
Feb 12 00:01:02 dearestlinux in.tftpd: RRQ from 192.168.11.1 filename firmware_WMR-300.ram
and maybe errors...
Ok, so... disclaimer:
I just added LuCI (+LuCI failsafe) to the modules, and generated the ramfs version.
But I'm just a member, like you. In other words that's not an official OpenWRT version...
Anyway, if that seems to go well, change your PC NIC network to 192.168.1.168 / 24.
And after you could load the initramfs version into the router, do http://192.168.1.1 and dear LuCI will immediately offer you to upload a firmware. Take the official

Reboot after 5 minutes ... and do open the same URL -
