[size=14.6666669845581px]Hi all,

[size=14.6666669845581px]I have a problem with [size=14.6666669845581px]Zenmuse Z15 GH4.
[size=14.6666669845581px]

At startup of gimbal it keeps spinning and doesn't initialise. It always went round and round.. When I repower it continuous spinning at startup again and no initialization happening. All radio switches about gimbal working properly (Zenmuse is receiving the commands well on Zenmuse Assistant) and video out from cam is ok.
[size=14.6666669845581px]My setup is like: A2 + iOSD II + Zenmuse Z15 GH4
[size=14.6666669845581px]Anyone got any ideas?

Does any one had the same problem? any one has any idea how to fix it?

i can't see your pix

I did not post any pic. do not know why it shows like this

anyone any ideas? i stuck with the not working device...

How is it possible to downgrade the firware of Zenmuse GH4?

Can you explain your setup a little more, how is it getting the control signals? separate Rx if so have you checked your trims on the channels.
