Good morning from Jetpower..
even from here we give support..
you need to change the special assist firmware
download this : https://www.dropbox.com/s/ult1kzg4ex...ssist.sfw?dl=0

after this rename that file to firmware.sfw
put it on a sd card
insert in the ctu and power it on .
2 leds will toggle
for about 5 seconds and all should work ok.
