Hi!
I've downloaded the Zenmuse Z15-GH4 (HD) Assistant Software v1.2. However, I can't update the GCU to more than v 1.4 (1.8 should be available?) and the IMU to more than 1.10.

There is also no version shown for the HD-AV, and of course it can't be update at all...

Can anyone help me out?

Are you running a Z15-GH4 gimbal or do you have a GH-3?

having the same problem with the Z15-GH4 (HD) !
gimbal is working fine but the HD-AV is not working at all after the update... on the 1.14 is was working sometimes...
so how i can downgrade or when is there coming a fix?!?

It sounds like a bad hd/av board, I would suggest to contact support.

hello, could you please screenshot the Upgrade and Info. pages of your assistant software to us for a good look?
