To clear the configuration on a boonky non-IOS router such as the 775m, do the following.
- Find correct links for the links below. Cisco rearrange their site quite often, which is a pain in the arse.
- Download the following files
- Connect to router using console cable at 9600 8n1.
- Power cycle it and press ESC during POST.
- Upload the 760erase.hex file using an ASCII transfer (cranking the speed up to 115200 at this point is a good idea!)
- When it reboots, upload the second firmware.
