Hi All,
I totally understand how you feel now, sincerely sorry for any inconvenience caused.
Our engineers are aware of this situation and working on it now.
Sorry they have not started to push the beta firmware to your accounts.
While I will keep an eye on it's progress and update the info to you timely, truly appreciate your patience!


So, What ever happened to the Timely updates??

"Upon verifying with our R&D department, we have already raised this concern and they are currently addressing the issue to be resolve the soonest time possible for this issue. They are going to release a new app update to fix this. "

Though I don't think a new app update will resolve this issue

Dear DJI. Every day you don't communicate, don't fix the current firmware, don't allow us to load the previous firmware and don't resolve the long standing limitations such as the altitude restriction is another day that more users flock to the third party firmware loading solutions and hacks. You have lost control of your platform and you have only your management in China to blame. Whatever good will you hoped to achieve by placing restrictions on your products you have lost by encouraging hacking of your firmware. This was predictable from the beginning. You should have known it would happen.

Yup, and to add more to this they clearly stated before updating in the notes shown on the screen that we could downgrade if we were not satisfied by the new range limitation for non DJI apps. (which was a lie)

The real issue is that no-one will trust new firmwares from DJI and keep their drone as is.

Which will be an issue for DJI because they probably have to update the no fly zones of their drones to be able to comply with different countries laws.

Of course the other issue as you stated is that hacking drones is now becoming more popular because of their slow response and that leads to discoveries such as the ability to unlock the CE restrictions on the radio range/frequency with such hacks...

Yup I can even tell you they can change it from 0.09W (CE) to 0.4W (FCC) and even to the maximum supported by the P4 which is 1.5W without even hacking/changing the firmware.

I won't link it here to avoid conflicts but I can just tell you I ran by it reading this whole thread while trying to downgrade my crippled P4.

It just proves the right hand doesn't know what the left hand is doing. It's amazing how a Chinese company would rather lose respect than admit an issue and keep users updated.

I work in software, I know things go wrong - therefore I'd be respectful and understanding if I knew what had gone wrong, and what was being done to resolve the issue...even if it was going to take a while to fix. Currently to me, DJI is a disaster.

Yep, We are all looking for the acknowledgement from Dji, which isn't likely to happen any time soon

Don't waste your time with theorys...Made in china... just say thank you to the users that find a solution to use again like before the phantom 4 !
The simple reality is to never update your aircraft firmware, never ! and never trust what natalia and other dji support says !
Best regards and have a nice time to fly !

"Don't waste your time with theorys...Made in china... just say thank you to the users that find a solution to use again like before the phantom 4 !"

So where was your display device made ?

The simple reality is never update anything ever, and never progress. The firmware you are using is already an update to what came before. Your theory is not good. The users who 'found' a solution likely googled for hacks, not difficult. Good luck to those using hacked firmware attempting to make a warranty claim. Meanwhile DJI generally produce fixes for their firmware.

Wow Geebax. I don't think you have a clue how intelligent these small time tinkerers are, then again, I wouldn't expect you would. About all you seem to be good at is insulting people.

Now I'm a bit wiser, had no idea what Kool-Aid was, probably doesn't mean too much to people outside of USA. Is this phrase some kind of compliment ?

There is nobody, nobody at least that does their research, will ever trust an update again. They have shot themselves in the foot this time. People are very lucky that a dedicated few have put forth the effort to come up with a solution that renders the need for DJI obsolete.

What happens if you use Litchi or Autopilot?  Does it still fly with the shakes with those apps?

Wonder if the new IMU calibration of using all six sides has something to do with it?

Does the same when using Litchi, stills fly aggressive when manual flying or in an autonomous flight

Its really easy. It sounds much more involved than what it really is. You dont have to load multiple versions of the firmware. You just have to flash it a couple of times so that all the data is written. When we say "flash" it just means you select the "flash" tab again after it finishes the first time. Basically you just download the DUMLdore file and when its done click on it and an option to unzip will appear at the top of the window. You click unzip and it will ask you where you want it unzipped to. Just right click on your desktop and select "new folder" and a new folder will appear on your desktop and then you just name it what you want to call it. When you unzip DUMLdore you will select that folder you just made and it will unzip to there. Then you just go to that folder and select the second file down. Then DUMLdore will open and you will see a window with 3 tabs, "Backup", "load", and "flash". Hook up your p4 to the micro usb cable it came with and plug it in your usb. First you select "backup" and it will save your current firmware into the DUMLdore folder. You really wont need it again but its just good practice to back it up just in case. After you download the firmware file 0602 you will select "load" and it will pop up a window that asks you what file you want to load. Select the firmware file you downloaded (0602) and then select flash. It will wright it to the p4 and after its done select flash again. After it finishes your done. You only need one of the firmware files. You can use either one but most people are using 0602.

Thanks Duchunter I carried out the process with no problem and the P4 has flown great.

Cheers

Almost 1 month since its failware was release and we don't have an official position.
You DJI, should at least allow us to return back to the previous version.
I use my phantom to work, and I am losing a lot of jobs because these issues.
The impression I have is that Phantom 4 isn't important to DJI anymore, they are investing their time only in P4P, P4A, Spark and Mavic. It's very sad.

https://en.wikipedia.org/wiki/Kool-Aid

As much as I like the DJI product line, and will be dropping some serious coin to buy a few of their products soon, I am very leery of their software in general.  It should come as no surprise that they continue to make software/Apps that have increasing levels of restrictions and layers of controls.  These policies are being developed in an environment where living under such restrictions and controls is well entrenched.  Most of the users here that have issue with these additions and changes are coming from folks who don't normally live under such rule sets i.e. big brother will decide for you what you can and can not do, by whatever means it deems necessary to enforce those rules.  For now, it all remains workable to one degree or another and to too many sheep out there they are fine with it.  Let's hope that we don't end up with an update one day that won't even let us turn on the motors without verifying who we are, where we are, and then reading a restriction disclaimer that threatens our ownership and maybe even legally if we deviate from those factors or we are found to have violated some rule.  I think it's safe to assume now, that by requiring one to "log in" to operate their aircraft it is potentially a step in that direction, and who is to say they are not already collecting data on users because of that restriction, don't be surprised if they are.  From a non-Kool Aid drinking DJI fan.

Hi, I found a notebook with Windows and did all the procedures.
In my case, it didn't work properly even after the downgrade.
The engine sounds are Ok now, but my P4 is still running fast (without sport mode) and drifting when hovering. When I came to land, it bounces as a yoyo and touched the land very hard.
It's need to calibrate anything else? I've calibrated IMO and compass.

Are you getting any VPS errors by any chance? My P4 is experiencing the same issues because I've got vision sensor errors and it's running in sport/atti mode

Somehow, i fix the new firmware to work just great. What did i do?
1) refresh 6 times the aircraft with the first battery. Some of them did without the sd card, some with the remote controller closed and some with the sd card in, and the remote control open.
2) did exactly the same with the second battery. Of course after every refresh, i was restarting the aircraft.
3) Then i calibrated the sensors with dji assistant twice (one for each of my 2 batteries)
4) I charged every battery full
5) Then, and for me the most great thing to do, i was waiting for about 3 hours for the aircraft to be not hot. Then find a 0 zero flat surface, and did imu calibration 2 times for each battery.
6) Then calibrating compass for each battery
Maybe many of those i did, was too much, but you have to see how rock and stable is my P4 now. And of course with the 4.1.5 dji go4 instslled.

Before you did this, had you upgraded and had flight instability problems as the others ? And by carrying out your procedure you ended up with a stable aircraft ?

It's interesting because I wonder if the error is in the software carrying out the upgrade procedure perhaps not installing or doing checksums on downloaded files correctly; rather than the firmware being faulty. I've seen a couple of reports now where repeated attempts has sorted things.

OMG, yall dont have cool-aid in the UK? Man, you dont know what your missing mate! Want me to mail you some? The phrase "drinking the Kool-Aid" comes from when Jim Jones's congregation all committed suicide  in 1978 in Guyana. They put cyanide in kool-aid and then they all "drank the kool-aid" killing themselves because Jim Jones told them to. They blindly did as they were told thus giving us the phrase.

Did you flash it multiple times? It appears that all the data isnt written the first time and it that causes some things not to work. If you just flash it 2 or 3 times that will insure all the data is written and fix any issues.

That is interesting when downgrading the firmware people are flashing 602 twice to get it to work maybe just flashing the new firm ware twice will fix it or as you have 6 times.

As you can see in these 2 threds I attached here. dji THOR and SUSAN have no idea about our problem which you promised me is currently being working on, and that's the status for few weeks.
Are you sure your staff is working on the severe stability issue with a new fw?
