I tried to upgrade the IOS on my 2801 from 12.4(24)T1 to 12.4(24)T3 to get around a particular bug we were hitting. I FTP'd the IOS over and rebooted... I didn't verify the image before rebooting and I guess the image didnt fully transfer. The router now boots in ROMMON.
I'm fairly familiar with ROMMON and did the necessary configuration to get tftpdnld set up. The router was able to connect to my TFTP server and start to transfer the file, but after a while, it would just start to timeout. Both the TFTP server and the Router were saying that the remote side stopped responding. TFTP server and router are on the same VLAN.
My next idea was to set the speed on the console port higher than 9600 and then xmodem the image over. I've done that before and it's fairly straight forward. I followed the directions here to increase the speed of the console port to 115200bps : http://www.cisco.com/en/US/products/hw/routers/ps259/products_tech_note09186a008015bfac.shtml
I reset the router and established a new session via Hyperterminal. All I'm seeing now is Jibberish (that's an official term ). I've played with the settings in Hypterterminal and tried every port speed from 9600 up to 115200, still just junk. I've also played with the Parity, stop bits, and flow control. No luck. I tried the same with Putty as well and power cycled the router a few times just for good measure.
Any ideas how I can unbrick my router?
