Downgrade Ubiquiti AirOS

Because we are "jailbreaking" the Ubiquiti router, we have to downgrade to an older version of their proprietary firmware first. Using a tool called TFTP, we can do this quite simply.

1. Download the firmware file you wish to flash
2. Launch a command prompt/terminal, and enter the following, one line at a time:

tftp

tftp> connect <device_ip>
tftp> binary
tftp> rexmt 1
tftp> timeout 60
tftp> put <firmware_filename>
