I just got a used smart controller on offer up. It is running a old version of Firmware. I have tried using smart assistant 2 for Mavic on a pc and a Mac it downloads transmits then fails at 15% every time. I do not have an sd card inserted. I have factory reset the device multiple times. I found some instructions online that told me to delete 4 files off the device and try again. If I use the built in firmware update option it also fails at 15%.
Any tips on things to try. If I send it in to dji what should I expect to be charged for a repair?
