Okay.

I just got my new DJI Zenmuse h3-3d and install it on my Phantom 2,
Plug in the battery, and power on the drone..

Everything was fine, the gimbal was coming to life..
then I plug the drone to the Assist Software PH 3.8, to change the tint control gain of the gimbal
after that I checked for update, and the software told me to update..
So I did an update for H3-3D IMU to version 1.0.0.12.
then 20-30 sec later get and error:

"Upgrade failure! Please power cycle and try again!"

So then I did turn off the drone and for trying again,
but this time the Gimbal was not recognize by the sofwate.

I did a reseach on youtube, and found how to reset it..
that did the trick, the software recognize the gimbal with no framwork version.
then I click Upgrade its loading... and again! same problem!!

it seems like I have a problem with the installation of the frameware..
I try to reset my drone frame work, but not success

Please help me I am desperate
I tried more than 20 times
