Restore mode

If you want to upload firmware to router by tftp, you will have to turn your device to this mode. The procedure is following:

  1. Turn off the device.
  2. Press and hold the reset button.
  3. Plug the device (still hold the button).
  4. Wait until the Diagnostic LED (second from the left) starts flashing quickly. (This will happen almost immediately.)
  5. Now release the reset button. Your router is in Restore mode.

TFTP installation notes

Set your ethernet interface into static mode (IP address, netmask, default gateway, put your router into Restore mode and upload the firmware by TFTP using the following commands (replace XXXXXX with wpe72):

$ tftp
tftp> binary
tftp> trace
tftp> put openwrt-ar71xx-wpe72.bin

Diagnostic LED will now stop blinking for a while; if the flashing procedure is successfully done, it will start blinking slowly. Now reboot your router manually (turn off - turn on) and OpenWrt will boot.
