So, I just received Osmo handle and X5 adapter (among several peripheral accessories), trying to utilize X5 camera from my venerable Inspire 1 Pro. On initial power-up, however, X5 doesn't want to perform it's ritual dance. The gimbal remains lifeless (although internal fan starts working), displaying yellow LED light. I tried to perform obvious FW update, but no success: camera remains limp with yellow light for hours. Gimbal installed back on Inspire works just fine. What am I doing wrong?

EDIT: Well, the gimbal will remain crippled until OSMO receive DJI blessings ... I mean activation. This procedure, convoluted as humanly possible via WiFi, is described in official video tutorial for OSMO Mobile, but not a word of explanation for customers skipping the Mobile stage and starting the Osmo adventure with Pro incarnation. Oh well ...  
EDIT #2: Forgot to mention ... Obvious FW update procedure couldn't kick in, displaying stubborn solid yellow light on camera ... Until I decided to replace Sandisk card with Lexar brand ... boom! Go figure ...

Hi - I did the same thing with the purchase of an Osmo handle to extend the use of my X5.  I have found that the connections between the handle and the gimbal are very critical (including the locking mechanism), and I would check that.  The other connection (between the lens and the camera) is also critical but more for the picture transmission to the tablet or phone.  Good luck - hope this helps.

I don't know what else I can do to establish gimbal and handle communication ... Shake, wiggle, push, pull - the gimbal remains crippled like Stephen Hawking (alive but not able to move) ... My apologies for unfortunate comparison to one of the greatest minds of our time ...
EDIT: After several hours of Internet research and hair-pulling I've got my OSMO Pro system finally working, even with Focus Handwheel 2 and CrystalSky Ultra Bright monitor. It should be much easier with step-by-step written instructions, but perhaps I'm asking for too much. Oh well ...

Hopefully it is stable (and repeatable!)  All the best!

Glad to know the issue has got figured out, hope you have a great time with it.
