Zenmuse z15-Gh3 out of control roll spinning after initialisation. Anyone had this issue? I have seen some youtube videos but none have solution. The spinning is so fast that it shakes the entire S900.

Cables checked, firmware re-installed , all firmware up to date. 1 out of 4 times it happens.

Any thoughts?

Can you tell me the GUI name and version to be used for upgrade? Also, what all upgradable components and version number are upgradable?

In my Zenmuse_Gh3 GUI, it shows Main Controller v2.0 and IMU 1.6

But, the website says different upgradable component and version.
@Zenmuse Z15-GH3 Firmware IMU v1.6 2014-04-24
@Zenmuse Z15-GH3 Firmware GCU v1.4 2014-08-11

I have another software called DJI gimbal assistant 1.1 - This gives me different view.
GCU - 2.0
IMU - 1.6
HD-AV - ...

Didn;t checked video, but i know now why the problem is occurring . If you see the Zenmuse-GH3 assistance software v1.0 is showing and downloading the firmware for GH4 .

DJI, can you fix the issue ASAP?

After updating Z15 (GH3) behaves abnormally during initialization. When initializing crashing into GH3, the viewfinder is captured on the back of the ribbon cable. Video transmission is not working (still flashing red LED). Gimbal has not adhered to stabilize the camera travels.

Already sent.. scroll through and you will find my email and probably 10s of emails . The GH3 assistant software got a bug and is downloading and updating GH4 GCU and IMU firmware on GH3 GCU.

If you have a Z15-GH3 and updated on the DJI website you should have notice that they removed the GH3 and replaced it with GH4. The problem is this. There are 2 different updates for the IMU. One is from April and one is from July (July on the GH4 site). Both IMU updates seem to be ok but if you updated the GCU to anything over V1.4 you will lose video. I have been able to reflash back down to V1.4 and now have video. Go here:  http://www.dji.com/product/zenmuse-z15-gh3/download  but beware the GCU still wants to go to V1.8 or 2.0 even though the website only lists 1.4. As far as DJI is concerned, I have sent 3 different support tickets reporting in detail about this issue. I keep getting the same response back to send my unit in for repair even though if you downgrade the unit (which ever unit they are talking about) works by downgrading

Thank you for contacting DJI.
The issues that you're describing require for you to send inyour unit for repair.

We never upgraded our firmware with GH4 assistant. At least who knows Z15 is for GH2 and NEX5/7 series, Z15-GH3 for GH3 which is listed once you click on Products and not look at the Products drop down fancy menu.

The bug is introduced with the new firmware notification to make GH3 gimbal compatible with A2 2.4 firmware. The assistant software for GH3 is installing GH4 v2.0 GCU firmware and possibly IMU too.... there is no alternative at this stage to fix until DJI fix or release GH3 GUI version 1.01 or 2.0.

IF you have initially downloaded GH4 software to upgrade GH3, it is  a user fault. Always check the release notes PDF to  check for which supported components the upgrade is for.

Agreed but there was a DJI recommendation (Support) to update the firmware to GH4 thus the reason they removed the GH3 from the list. It was suppose to be needed because of the LightBridge updates and the wiggle that the previous update caused. There are a few folks who did this recommended update and lost video or had other issues. You can uninstall the Gh4 assistant and reinstall the GH3 assistant but the GCU, even though it should only allow V1.4, ignores that and automatically updates to 1.8 or 2.0 which virtually puts people who followed the recommendation into never never land.

Guys, during initialisation, does the gimbal do a 360 degree rotation on tilt axis? Mine doesn't do due the converter for GH4.. but my retailer said that is a not a issue and this gimbal worked like that with GH4 for almost 1 year.
