Can I install only the gimbal firmware to Typhoon H480 ?

[allu]

I will find out that can I install only the gimbal firmware version to the Typhoon H480.
For example downgrading the gimbal version from 1.25 to 1.22 and then installing the v1.25 back.

There is N/A on Gimbal version section.

And where I can download old Typhoon H's firmwares ?

In some cases it works, in some cases not, however, it is worth to try:

CGO3pro gimbal controls not working

The green light is status of the camera. Not the status of the gimbal. At least not under the normal start-up circumstances. First caution is don't mess with updates anymore for now. It's probably not a firmware issue, and the only possibility would be to make things worse. We can come back...

I just tried to downgrade the Typhoon H with your procedures, but I did not get it updated.

I copied the TyphoonH_Ver2.25_A.bin file to the sd card and then tried to downgrade it by using standard update procedure.

First it is checking the firmware and then it informs that firmware update success, althought there is no any changes happened.

I doupt that there is some data wire broken between gimbal and camera, because there is N/A in gimbal and autopilot version sections. Only the camera's firmware version shows correctly. It can be tell why the downgrading fails.

Can you tilt and spin the camera? If yes, UART function from drone to gimbal is up and working.
Also check the telemetry file in flight logs from ST16. If there are datasets available with fsk_RSSI = 0 then also gimbla to camera is working and we can focus on gimbal firmware. If not I would assume a hardware problem.

Tilt and spin are working and there is negative values between -10 to -45 in the fsk_rssi column.
I measured the wires between camera and gimbal, those wires are working end to end.

So, how can I do the downgrade procedure ?
I tried your linked downgrade procedure, but it did not downgraded the firmware.

I still have a camera where I couldn't downgrade the gimbal firmware. If I can find a way to overcome this situation, I will post it here.

Please be aware of a potential problem if you do not know for certain the version of your current gimbal firmware.
Some few CGo3+ cameras came with version 1.27 gimbal firmware. The gimbals associated with that firmware use a different IMU. And the IMU is not compatible with ANY other gimbal firmware versions. If you downgrade version 1.27 firmware to any other version, the gimbal is bricked. I do not recall for certain if returning to version 1.27 will recover it or not. I also don't believe you can re-install version 1.27 anyway.

If you can't verify the version on-screen, you can remove the nose cover from the camera and look at the IMU. If you have a "boxed" type IMU, it will only operate with 1.27 firmware.

See CGO3+ Gimbal fails after updating firmware to the latest, please help!
