Hi I tried to upgrade my WRT to the dd firmware. It turned into a brick. I can use the pin 16 trick and get it to ping. I then use the tftp to download the official linksys 4.20.7 firmware. It says the firmware upgrade was a success. The red light slowly starts flashing faster until it stays on all the time. The router is now a brick again until I ground pin 16 again. Any ideas?
