So, first, the H3-3D started experiencing the yaw-jerk-left phenomena. And as standard/as always, the gimbal is really good at hitting the safety pins if the yaw motion is too much.
Now, that same motor (the yaw motor) doesn't finish its calibration, and sounds like it is struggling through every motion. The gimbal almost looks like it is doing "the gimbal dance" that we've seen in the latest firmware update, while sounding like it is struggling (almost like a grinding sound).
I'd flown a number of flights, done nothing with the Phantom 2, except sit it upside down so nothing was on or near the gimbal, took it back out for the next flight, stuck the battery in, and turned it on. And suddenly it's acting quirky and won't finish what seems to be its calibration.
I sent DJI a "report" through their useless online system... I call it useless, because apparently reporting warranty issues through their tool makes them send a response saying to call them for warranty issues. How nice. I will do that tomorrow.
In the meantime, here's my first note to them... I will let you know how this works out, but honestly, I have a feeling that the problem is in the design itself (as noted in my note to them):

Subject: Gimbal Failure - need replacement
Message: Hi,
I have only flown 8 flights so far...

It appears I am having a failure of one of the motors/servos on my gimbal (the top most one that orients left and right).
This seems to be the same servo that has problems causing yaw-jerk. My gimbal first started experiencing the yaw-jerk-left issue, and now, when the Phantom 2 is turned on, it never finishes calibrating - the top motor kind of makes a grinding sound and continuously moves left or right.
I have a feeling you have TWO major flaws in your gimbal design, and I need this rectified, since I spent a lot of money on the poorly designed gimbal.
(1) the gimbal is not strong enough to hold yaw setting when flying at the speeds the Phantom 2 is rated for
(2) the gimbal mount safety pins obstruct the gimbal's motion during certain yaw motions
I believe both contribute to excessive wear on the gimbal motor, followed by increased yaw-jerk-left incidents, followed by gimbal motor failure.
Please let me know when you can send a replacement gimbal (and where I should send the defective one). And please let me know that you are addressing your design issue.
We have a film shoot we are preparing for in just ONE week, and would really like to get this resolved before we film. We'd love to plug DJI in our credits - as opposed to post that our aerial shots were impossible to get with our setup because of a flaw in the gimbal we bought from you.
Best,
Robert
