===Pick a firmware===

* vehicle/openwrt/kamikaze_8.09/openwrt-brcm47xx-squashfs.trx

===Install using TFTP===

To install OpenWrt using TFTP or the ASUS firmware restoration tool you have to put the router in diag mode. To put the router in the diag mode, do this:

* Unplug the router's power cord.
* Confirm your PC is configured to request an address via DHCP.
* Connect the router's LAN1 port directly to your PC.
* Push the black RESTORE button using a pen or such, and keep the button pushed down.
* Plug the power on while keeping the RESTORE button pushed for few seconds.
* When you see a slowly blinking power light, you are in diag mode.
* Now the router should accept an image via TFTP or via the ASUS firmware restoration tool. 

In diag mode, the router takes address 192.168.1.1. It responds to ping, so you can confirm that it is in diag mode and ready for the tftp by using "ping 192.168.1.1".

* Execute the TFTP commands below:
      tftp 192.168.1.1
      tftp> binary
      tftp> trace
      tftp> put openwrt-brcm-2.4-squashfs.trx

* After the TFTP upload is complete, wait at least six minutes. The firmware is first loaded into the RAM, and then flashed. This process takes a little time, and to ensure that the router is not bricked you should wait six minutes.
* The router will reboot itself automatically after the upgrade is complete. Rebooting may take a while. It might be the case that the router does not reboot by itself; if this happens it should be safe to wait for the period mentioned and then to do a manual reboot (pull the power-cord).
* You are done! You should be able to telnet to your router (IP address: 192.168.1.1) and start configuring. 

NOTES:

* Netkit's tftp doesn't work quite often; use atftp.
* After TFTP upload is complete, DON'T reboot (replug) too early! It might brick your router.
* The ASUS WL-500g Premium does not revert to the 192.168.1.1 address when starting the CFE bootloader, but uses the LAN IP address set in NVRAM. Try this address if you have difficulties.
