Downgrading would require you to put the K2 into firmware upgrade mode (Flashing white LED.


To perform this, you would need to press and hold down the two buttons on top of the unit WHILE connecting the USB cable to your PC until the flashing white LEDs begins. Only then will the software detect the K2 and allow it to perform the downgrade/upgrade.

Thank you this did in fact work. All tutorials made by KEYMANDER said to do it before plugging in not while. Thank you
