TFPT would definitely be a time saver compared to any of the [xyz]modem protocols. I wonder if this would also work on any of the older model routers.... Thanks for the update Colin!

However there is another method in place now that is actually faster. You will need a tftp server to use to upload your IOS image. I typically use TFTP32 by Jounin.

Step 1) Connect your computer to the WAN port of the device that you need to recover. Manually set the IP on that connection.

Step 2) Open your tftp server and set its directory to wherever you have the IOS image stored on your computer.

Step 3) Configure the WAN port in ROMMON. The commands for this are as follows:
IP_ADDRESS=IP address of the Ethernet port
IP_SUBNET_MASK=subnet mask of the Ethernet port
DEFAULT_GATEWAY=the default gateway
TFTP_SERVER=the IP of the TFTP server (your local computer)
TFTP_FILE=the file name of the IOS file

Step 4) Start the download of the file using the “tftpdnld” command in ROMMON.

Step 5) Reset or power cycle the device.

*Note* Depending on your set up you may need to specific the file to be opened at boot. Do this by sending the “BOOT=IOSImageName” command where IOSImageName is your IOS file
