Connect your device to your computer with a USB cable. If you computer complains about needing to format the new drive, cancel the format command.
Double click the reset button on your device, this will put it into boot loader mode.
A new drive will then appear on your computer. Open this drive and you should see three files: CURRENT.UF2, INDEX.HTM, and INFO_UF2.TXT
Copy the appropriate firmware-xxxxx-1.2.x.uf2 file from the firmware zip file onto the new drive.
Once the file has finished copying over, the device will reboot, loading the new firmware as it does.
