Flashing DD-WRT
By kings


 * 1) remove power from the DIR-412, then find something to poke the reset hole.
 * 2) keep pressing the reset inside that hole and give power to the router, keep pressing until the power light turn yellow and start flashing.
 * 3) connect a lan cable between your pc and router, you need to manually set your pc to 192.168.0.2
 * 4) access 192.168.0.1, and you will see an "emergency firmware flashing" page
 * 5) select the dlink-dir300-factory-webflash.bin and click something like "upgrade"
 * 6) wait till it finish and you will be able to access the new dd-wrt at 192.168.1.1, also remember to change your pc to 192.168.1.x

but I cannot get the "WAN" port to work as WAN right now, it sort of stuck to lan... WAN interface never get an ip address. I did not try any USB HSPA modem though.

enjoy!
