To clear the configuration on a boonky non-IOS router such as the 775m, do the following.
- Download the following files
- 760erase.hex
- c760-in.b-TPH.43.1.bin (requires CCO login)
- 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.
