That is a lot of steps to go through, be sure go through the steps again & confirm everything is setup correctly in that tutorial.
Be sure your pc and router are the only things hooked up together and your pc is plugged into port 1.
After reading up on the Archer router that you have, in recovery mode it will set itself up with IP 192.168.1.86 You need to setup your Linux machine to ip 192.168.1.2 Subnet mask 255.255.255.0 Gateway 192.168.1.1
Once your ip is setup you need to confirm that your tftp server service is running. With the commands depending on which one your system is using according to the tutorial.
# /etc/init.d/xinetd restart
# /etc/init.d/inetd restart
Your factory image.bin file needs to be in the..
Now these steps are not clear anywhere on the net so I am speculating a bit here....While the router powering up hold the reset button down with a paperclip till you see the routers power light flashing orange, continue to keep holding down till it flashes green. Go ahead and release the paperclip and the router should pull the image off the linux pc. Give it some time to upload and you may see it cycle once or twice.
You may try this method instead with a different TPFT Here However, before installing the new one you should remove the xinetd tftpd first.
sudo apt-get remove xinetd tftpd
sudo apt-get purge xinetd tftpd
If those methods fail to work you may have to try a different method with a Windows machine and a TPFT2 and telnet push the file to the router. Something like a recovery method Netgear routers use..Here
Hope that helps you out..
