just to update, I loaded the speed class HD 1000000 v.3.1.6 file directly onto the firmware 1.07 by opening it, and going into the decoder information, now the verification code also appears.
i, I wanted to register the qviart dual on the metamango site but in addition to the serial number of the decoder you have to enter the verification code of four numbers which the decoder does not display, can anyone help me? Thank youh
