the dji system assistant told me to update the firmware in my dt7 controller the update failed now controller doesn't work please help me

Hi Bob, we're sorry to read the troubles. Please try to connect the DT7 to DJI Assistant and update again to see whether it works. If still not, I'm afraid that you may consider sending the unit in for diagnosis: https://www.dji.com/support Sorry about this.

I need the older firmware for the dt7 mine doesn't have the trainer connector or the battery meter I think that is the problem
thanks again
