Make sure you have DHCP and the TFTP you configured has the FW for the phone before attempting this or most likely you'll end up with a brick

Step 1 Unplug the power cable from the phone and then plug it back in. The phone begins its power up cycle.
Step 2 While the phone is powering up, and before the Speaker button flashes on and off, press and hold #. Continue to hold # until each line button flashes on and off in sequence in amber.
Step 3 Release # and press 123456789*0#.

You can press a key twice in a row, but if you press the keys out of sequence, the factory reset will not take place. After you press these keys, the line buttons on the phone flash red and the phone goes through the factory reset process. Do not power down the phone until it completes the factory reset process and the main screen appears.

Thanks, this is great information. I tried this process and it did not work. DHCP and TFTP are working. I can connect another phone to this port and it works fine. The phone is sitting at the CISCO screen with Copyright 2002-2007.
