Turns on, gimbal initiates normally, then it droops. Beeps three times, solid yellow light on the left, solid green light on the right. Record indicator on the front of the camera is solid green. The camerra feed can still stream through the app, it's just the gimbal that doesn't work.

The setup is an Osmo handle, X5 camera, X5 adapter.

Tried new card, tried no card, on most recent firmware, tried rolling back to plain osmo firmware but I assume it won't recognize it because it does the same boot up fail. Tried multiple lenses, tried no lens. Using the 14-42mm pancake zoom, the lens will telescope in and out repeatedly as if it's stuck in a reboot cycle. Tried resetting wifi, no success.

Hi, the link says file removed.

Is the Osmo Pro new? Are you using Android?  Have you activated the Osmo Pro? Sometimes it's not activated and you need to find an iOS device to activate it.  

Or it worked before, but suddenly stopped working? If this is the case, please contact support@dji.com and send it in for inspection. Thank you.

I have the same issue. It is new and I activate successfully the osmo using and Android. How can I fix it?

I fixed it. I update the firmware.
