Hi,
The new firmware is now available as part of the updated QTool installation package. It can be found in the "bin files" directory. https://www.nxp.com/webapp/sps/download/license.jsp?colCode=Connectivity-QTool-Setup
To update the dongle firmware, short TP5 to ground (you can use the USB shield) and press the reset button. You should see a "CRP DISABLD" drive enumerate. Delete the firmware.bin file in that drive, and then drag-and-drop the new firmware.bin file into that drive.
