Hi

My gimbal do not startup after a ZEN IMU Fw update.

How to fix it ?

When i power the P2V+ the gimbal do not make any movement and reproduze a contine sound like a buzzing..

I can connect the camera on APP, take photos, but GIMBAL do not work

In this case,  the surest way is to contact the dealer or local DJI Service Center and let them deal with it.
They will try their best!
