I can't updating my mk3 s88. Please help me and give me a resolution
Please try this trouble-shooter : Kontrol S-Series MK3: Troubleshooting Firmware Update Issues
Otherwise the especially for the S88 MK3 then it is suggested that you use an USB-C PSU capable of PD on the power port while also using a quality cable capable of power transfer (my personal suggestion is 20W to compensate for any eventual PSU quality issues). Or try a self powered USB-C hub with PD (power delivery) and quality cables that support both power and data transfer.
Or alternatively try an USB-C to A port adapter and then also attach an USB-C PSU capable of PD on the power port while also using a quality cable capable of power transfer (my personal suggestion is 20W to compensate for any eventual PSU quality issues)
Otherwise then please contact N.I. Hardware Support , Please refer to the page : How to get in touch with our Customer Care
@rzepetto Were you able to make it work? You didn't reply and I didn't find any support request from you.
