Motors wont arm after new fmware please help

hi im new to this and just recently bought the mode 2 quanum nova and after hooking to mission planner I updated to the new v3.2.1 and now my quad won arm the motors any help would be great since hk couldn’t seem to get me in the right direction

Probably the usual issue in that after a FW update you may need to recalibrate the RC, ESCs, Compass etc… All check the message log from MP as that will have extra info on what is stopping the ARMING from completing.
