And to dive into it further, here is a thread from a big DJI contributor and explains in detail about updating and issues if it will not update.

Ken, do you have the link to the thread?

Sorry for the Newbie question, but I am heading out to the desert tomorrow (first flight day) and wi ...

IIRC the update from v1.5 to v1.6 was mandatory. I had a WLAN connection and so the central status bar was red flashing "firmware update pending" (or similar). If I am not wrong I was not able to start the flight and I had to update.
When I read the v1.5 issue with the inflight power cut off (cold battery protection) I thought: they had to ground their A/Cs with the northern hemisphere flying in cold temperatures...

With v1.3 and v1.4 I had the impression of a flawless product. Shortly before v1.5 I had two inflight compass errors (on v1.4) on different locations. Since v1.5 I have the vibration issue and the A/C sounds generally louder when passing by (old ESC&motors).
I set the yaw gain to 85% which helps to eliminate the vibrations on ground idle (and maybe in hover; still have to test it).
Probably my props are worn out (maybe due to imbalance?, 88 hours) and I will check with a new set.
Everything else (video quality, horizon, performance (recognized the new v1.6 "cold temp reduced thrust" feature on a straight climb), video link, RC range etc.) is as good as of the first day (EDIT: or maybe even better).
What irritated me (or maybe underlines the v1.5 problems) is that the version history list in the release notes of v1.6 FW upgrade does not mention v1.5 (it goes straight from v1.4 to v1.6).
Regarding my level of v1.5/1.6 FW consideration I am somewhere "in between" compared to people having absolutely no negative effects and others having A/Cs shivering like mad and producing jello effects example videos...
Regarding the discussion about "new ESCs (motherboard) & motors" I trust DJI that they make no difference from the performance side. (They were open to communicate the better performance of Inspire V2's new motors). But I have the impression that FWs v1.5 (cold battery cut off problem) and v1.6 are optimized for these new ESCs/motors and so the vibration problem was introduced for the (EDIT: or some?) original configurations.
I am also wondering if cold temperatures in general are contributing to the vibration problem as they occured for me (concurrently with v1.5/1.6) in colder outside air temperatures. "nicwilson" has no problems in Australia with temperatures of around 30°C...
Just my thoughts (and massive round up) of all I have read the last month.
Sorry for the "lead desert" as we call it in German for a desert of hot metal typesetting...
Always happy landings!

I decided to return the bird and swap it for another since my dealer said they would.  I hooked up the new one just a few minutes ago and it works, no issues, right out of the box.  I have video and all on my Galaxy Tab 4.  I followed some of the other posts about making sure you use the link in the DJI site for the go app and made sure the debugging was enabled.  I also killed a bunch of unnecessary apps.  The app is telling me the firmware is out of date for the RC and the bird.  With all the other posts from people having issues with the firmware upgrade to 1.06 I am very skeptical about performing the upgrade.  Especially with what happened with the first bird.  Was it the firmware or a bad bird?

You are right. I think I read that too here and there.
But that makes not much sense  if new AND old configurations of "ESC&motors" are having the same problems (sometimes!?).
It could be a newly introduced temperature problem (battery protection through thrust regulation).
Or if just changing yaw values (reducing the yaw gain) makes obvioulsy a difference, the next suspect could be a change in drift avoidance. IIRC the inflight compass error (caused by high GPS drift values) was a subject in v1.4. Probably v1.5/1.6 has a changed yaw logic resulting in vibrations under certain conditions.

I hope DJI finds the reason soon. For me it is not such a bad situation as I am not using it for professional but for recreational purpuses and it also makes the whole story a bit exciting. Well except for those who are unable to use their product...
As long as my P3P does not fall out of the sky (e.g. into now well flooded meadows) due to material fatigue caused by vibrations I am happy. (I admit not going long term full power because somehow IMO the sound changed to a more nervous one.)

In addition to the no video issue, I had the alternating red/green led on the camera indicating update in progress.

This morning I managed after a few attempts to roll back to 1.05.0030 and seemed to get things working again. As the RC/iPad tell me that the drone software needs updating I thought I'd give it a shot and uploaded 1.06.0040 again. Again this seems to have worked and a short flight seems to verify correct operation again.

It will be interesting to see if another corruption of the firmware occurs, as that was obviously what caused the video problem.

If it is vibrating/shivering only outdoors (while indoors you have no problems), there might be a GPS related issue in addition to the temperature theory (e.g. new "cold battery protection" through thrust regulation?).
I yesterday tested ground idle+x indoors and got vibrations with yaw gains above 85%. Under the roof I had sufficient GPS signal strength, so that I was in P-GPS mode indoors...
I today will first try old props against new props followed by P-GPS vs. ATTI.
I personally think that the most probable vibration culprit could be a new yaw logic within v1.5/1.6 ment to prevent inflight compass errors in v1.4 (which can be very ugly in high winds + far distance + low light).  EDIT: this new yaw logic against compass/GPS drift would apply to both old and new ESC&motors, especially in GPS mode.

Hi Ken,

I also had to look at the video a few times until I saw the vibration "in action".
If you concentrate on the fore left arm in the video (rear right of the actual A/C) you can see the arm actually "jump up and down", especially in the last 3 seconds. (Unfortunately the arm gets out of focus during the most "obvious" phase...)

I have since cured the problem by first adjusting yaw gain down to 80%, which got rid of the vibration on the ground, then while in the air I dropped the roll & pitch gains to 85% which eliminated the shivering which only happened in gusts of wind.  This would support your yaw logic theory although con't confirm GPS affecting it.

I had the same thought about setting roll&pitch gains somewhere between 95% and 85% if "yaw modification only" wouldn't help (EDIT: especially in flight).
If you can't see any difference between P-GPS and ATTI modes it could be v1.5/1.6's new way of interpreting IMU values, especially yaw axis (but not only).
In addition to that the new battery protection thrust logic could especially "interfere" in low temperature situations.
As I said earlier: it also makes the whole story a bit exciting...
My video quality is not affected at all (for the time being) and I really pushed my P3P through hard cross over 45° angle flybys into turns and it never got an inflight compass error (as twice in v1.4).
My greatest concern is that the vibration (nervous noise in cruise) in the long term could cause material fatigue.
And now I have to go outside and test because otherwise it might get rainy and dark (and windy?).

It's not that I can't see a difference between  P-GPS and ATTI, I just haven't tested it yet.  It's currently too windy to fly outside the confines of my garden a few feet off the ground, where even there it's turbulent.  I don't want to risk bouncing off a tree or fence...and now it's raining as well.

Hi Ken,

If you cannot get rid of the vibrations with downgrading or lowering the gains, calibrating IMU, and the other suggestions listed in this thread then you will need to contact support for a warranty repair.

If you have intermittent video, it's not a firmware issue but rather a device issue. you need to use a device listed on the DJI website. Also try to disable all the apps running in the background and have your device in airplane mode.
Basically get your device's RAM to be as low as possible, that will make the DJI GO app work better.
