Please do reread everything above, especially about backing up.
1. Download the firmware listed above and rename it as described above.
2. Set a static ip: http://www.howtogeek.com/howto/19249/ho … windows-7/ 10.10.10.254
3. You need to setup a TFTP server to get the Openwrt firmware file onto the router: http://tftpd32.jounin.net/ Be sure to disable windows firewall.

Then hook up your computer directly to the router by ethernet cable and follow the directions above. Make sure that you have the firmware file in the directory of the tftp server, and that you have the correct interface chosen.
Finally, follow the flashing instructions carefully: Starting with power off, hold power button on router until the first white light comes on, then right away (have a paper clip in place already) release power button and hold the reset button for 25 seconds (use a clock, do not estimate). The router then looks for the file on a tftp server at 10.10.10.254 with the specific name "kernel" without the quotes and without file extension. You have setup that server and put the file in place. If everything works it will flash and reboot.
