Same exact issue. Rolling back firmware seemed to fix the issue.

Did an uneventful flight this afternoon.
Nominal runtime from battery of about 28 mins...

I was having a strange issue with my p4p with yaw, if I was moving forward and used yaw lft the aircraft would almost flip over to the right after firmware issue is gone! GREAT WORK DJI THANKYOU!

The update is for the drone and the batteries. You will need to charge batteries to more than 50% otherwise firmware will fail - 75% charge would be adequate. After the initial update using DJI Assistant 2 it will update the drone and the battery that is in the drone - take about 15 minutes. Then quit DJI Assistant, Turn off drone and swop out battery battery, reconnect to DJI Assistant 2 and this will then just update that battery - take about 3 minutes per battery. Repeat for next battery.

PhantomPhil...... Thanks for this detailed info about updating the batteries. Newbie here and watched the online video on upgrading, but it stops short of the complete procedure. Thanks for completing the process so can fully understand it.

Ive Just carried out this update & I now have a black screen (no image from camera) and cant enter camera settings either.

only able to switch between video & photo at which point I get a little bit of the image at the top of the screen with the rest going green????

The Surf is pumping this weekend & the sky is blue.... please help me  

CONTROLLER BOOT PROBLEM


Hi All,

i have a Phantom 4 Pro and the controller with Build-in screen.

When i turn it on there was an OTA update.  I downloaded it, install success, but the Controller not started again.  There is only the DJI logo but nothing boot up. (i try to leave in boot for 2H )

How i can fix this problem? There is a Recovery system to try to reset the Controller? Any idea?

@Jacko Lowe   

turn all off

start app then the RC and last the bird

if that works, reflash the firmware with assistent2

and be shure the firmversions are showing right in the about window at the RC

Same as you I updated my P4P. After update controller was useless, would not recover with Assistant 2. DJI is in process of sending me a new controller. Sucks that updates will do this.

Hi Bluemarley67 so they did fix the issue I had too?
So no more gimbal limit reached in P mode?
Let me know when you can thanks

Phantom  4 pro + I have signal problems I lose a signal less than a kilometer

armondo, my issue still happens here and there its much better than it was its much less, also I haven't seen the gimbal limit reached for a while! though wind velocity still shows a lot, and a false reading of object avoidance occurs when flying and no noticeable ojects to detect from ground

I always get this false wind alert as well. We were told it would be fixed in this FW update but it was not.... doesn't effect flying but message is a PIA.   donnie

Also get "high wind velocity" message, very annoying....

ever notice when high wind velocity shows up your drone starts to brake then flies again?
I notice on mine

Still got air craft vibration during manual take off, and landing.

I experienced this issue for the first time, right after upgrading to 01.02.0304 (the latest) firmware.  I've never seen anything like this before on any Phantom I've ever owned (3 Pro, 4, and 4 Pro).  If it helps, here's the details:

When landing - right after touchdown (a gentle one) - the aircraft began to "wobble" on its landing struts - almost like a destructive harmonic feedback loop had developed in the motor control part of the firmware.  As I always do, right after touchdown, I moved the left joystick all the way down to shut off the motors... but in the few instants that took - the wobble was increasing in amplitude.  I really don't know how bad it would have gotten if I'd allowed the drone to sit there and idle on the ground.

Could this be the same issue that's mentioned in the release notes for 01.02.0304? (Reduced aircraft vibration during light throttle takeoff)  If it is, I wanted to report that it happens to me (and others it seems) after landing too - and it's still present in the 01.02.0304 firmware.  If you'd like any sensor data or other information from my P4 Pro's post-landing wobbling/vibrating, I'll be glad to provide.

Thanks!

Tim

well, none of my obstacle avoidance sensors work. Had it a whole 2 weeks. Did firmware upgrade and calibration in DJI app now I can't see any radar nor does my test show they are working. I'll bet it's something with the calibration and firmware. What's odd is I can't even toggle the radar display on or off, it stays on, but isn't as bright of green. Support was zero help, after waiting 90 minutes, they told me to re-calibrate IMU and gimbal.   Didn't change anything. Thank God I have a 30 day return policy with vendor. The screens claim everything is normal but it's not!!!

You described the problem very well.  This happened to me as well on my flights 21st, Jan.  I actually went to my local RC drone/plane shop to ask for advice afterwards.

My observations / additional notes:

Not sure if the ambient conditions would effect the throttle down/power off procedure by holding the left stick straight down after landing but it was a windy day when this occurred.  In addition, the street that I was landing on was not completely level, as it was graded so that water would flow off to the gutters.  Could this be assisted landing / obstacle avoidance trying to intervene last minute here?  Just wanted to add some of my own observations and thoughts in the event that DJI is following this case.

I'm expericaning no sensors as well. they worked last flight but not this time around

Is it necessary to update the batteries? What is actually upgrading in the batteries? Sorry if my question has been answered elsewhere, I haven't found anything about battery-upgrades except your post.

When you do the drone update the battery inside the drone will be updated at the same time - you have no choice. If you only have the one battery you don't need to concern yourself any more.

If you have other batteries these won't have been updated and when you go out and fly your drone and then put in an non updated battery you will get a message on your screen saying "incompatible firmware" You will be left wondering what on earth this means and you will either a) return to these forums complaining about how rubbish DJI is because you don't have a clue why this message appeared or b) you decide to fly the drone and crash and come back here blaming DJI.

"Is it necessary to update the batteries" -  I just do it because it makes sense.  I am sure DJI have thought it necessary enough to provide the update for the battery. I have not flown my drone with a non updated battery and so I don't know for sure how necessary it is but I haven't run into any problems.

If you decide to fly your drone without an updated battery please can you post back here the result so that we can determine how necessary it really is - maybe we don't need to.

updated firmware, flew it today but got some major issues, could it be from the firmware update?

When I lost RC signal, automatic return home and land was trigged, when I got the signal back, I cancelled the landing from my phone and wanted to fly it a little more, this is when I lost control of the drone and it started crashing down. It seemed that the drone was still trying to save itself so the falling speed wasn't fast, and it was spinning in circles. Luckily it was not a high fall so it's not damaged (I think)

I just received my phantom 4 pro plus today! I wasn't able to connect the drone to the controller. Any advice. I called your support and they said there was a  problem with the app that is built into the controller. I am at a stand still I haven't even flown the drone yet and am kind of lots on what to do.

When I first got mine, it made me do a one time registration and I had problems because 1) My router locked it out from connecting, 2) after it connected it's IP changed but the controller kept the old IP address to connect. I think I kept getting the message "Call DJI Support". After turning everything off and back on the registration went through. Then I couldn't connect to the drone and this is sort of vague, I tried to connect the drone to my PC and Assistant 2 software but I was not successful. However after doing that and turning everything off and on again, the controller connected to the drone.
Were you able to do the initial registration?

Thanks, and yes I will listen to your advice and update both extra batteries because I really don't want to risk a crash. But I still don't understand what had to be updated inside these batteries.

I don't even know what needs to be updated in the drone but I do the firmware update just to make sure I have the latest and it will make some improvement. I don't know what improvements need making because my P4P+ flies perfectly as it is.

The battery communicates via telemetry to the controller, this is how it can estimate how much battery life is left and how much flying time is remaining. I would imagine that new parameters have been programmed into the battery firmware to improve accuracy of these estimates, but I am only guessing.

Just got the Phantom 4 Pro+ and was able to create a DJI account and login on the built in screen. When trying to activate the drone I get the Activation Failed (ServerBackFail) contact DJI support if error persists after restarting. Have restarted several times, reset the controller multiple times, tried using a different email and the same message keeps popping up. Any ideas of what I can do to fix this?

Some people were having a hard time registering their P4P+ when entering the name of the bird and using the "+" sign in the name.  When I registered mine I wrote it as "Phantom 4 Pro Plus" and it registered just fine.  It doesn't like the "+" sign in the name.

Hello Dji, I can't connect remote control DJI Phantom 4 it with Sony Xperia XZ 64Gb and Sony Xperia XA. Android Nougot Version 7.0. Pls update your apps for Sony Xperia XZ 64Gb.  I NEED use it ASAP

Any indications on when will new FW with solved gimbal issues be released?

Airwolf13 Posted at 2017-1-13 07:34
They now refer issues to their distributors GRADUS BH will no longer accept returns on ANY DJI peouucts. Period

They switched mine out. They just talked to me first to ask what I had done as far as DJI support first. I suspect they get a lot back from operator error and not equipment error. After they inspected the drone to make sure I wasn't trying to pull one over, they sent out a replacement the next day.

But i am still using DJI GO. is there any problem for this app

Thanks for Update...

where to get this firmware? at the homepage there is "Phantom 4 Pro+ Remote Controller Firmware v01.01.01.01 2016-12-09"

My p4p has number 1 compass dissconned but only give an error of magnetic interference fly with caution. I've tried to recalibrate the compass in a few locations and still shows compass 1 disconnected in the sensor screen. It is out of the box like this. Please help

No mention of fixing the "Battery Signal Error"? Hopefully this is addressed with this firmware.

Does HDMI work with the Phantom 3 Standard as well?

That's surprising to me, since I'm a big fan of B&H. But I can't blame them... DJI drops the ball when it comes to after-sale service.
