A Custom Firmware Download Tool for DJI Drones Written in C#

DankDroneDownloader

Giving DJI (and now, others!) the D ;)

There are many tools in the drone community which allow you to flash firmware, however DJI, much like Apple, would rather you didnt do this and they remove older firmware to more tightly control what versions their users are running. This isnt something that sits comfortably with me, you should be allowed to choose what firmware runs on your own devices and as such, i present you with DankDroneDownloader, or DDD for short. DDD archives both old and new firmware & with compaible 3rd party flashing software, will allow you to flash this firmware to your drone, camera, remote control or other device.

DDD is quite simply a custom written firmware download tool for popular DJI devices and Autel Drones. Not a windows user? Not a problem! DDD is also available in your (Chrome, Firefox or Edge) web browser over at https://www.dankdronedownloader.com . Of course we reccomend using the windows applicaion for the best features, but the choice is yours.

Always check https://dddstatus.com first! This page is updated with any known service impacting issues and is the place to go for this kind of information.

**NOTE: ** If you recieve the message "401 unauthorised" when trying to load the app, please ensure your system time is sync'd with an NTP time server. In 100% of the cases where this has been reported to me, the users system time was off, causing the server to reject the request.

Donations

DDD welcomes donations. The servers dont cost a huge ammount to keep online, but do of course have a cost. There's also my time in sourcing and adding new firmware and of course app updates, web system updates and keeping track of new models. If you wanted to donate some cash for my time or server costs, this is of course much appreciated & your name will be shown in the app and on the website. Thank you very much for donating if you choose to do so! :)

Security

I have been informed that some AV apps occasionally flag DDD as malware of various forms. This is caused by the way that some components of the EXE are packed to reduce filesize of the app itself

These are of course false positives. Rest assured nothing nefarious is going on! I will try to remember (i am human) to update the link below with results for the current app version.

Compatability

DDD has been tested to run on Windows 10 1607 upwards. You must be running Dot Net Framework 8.0 or higher however. If you are missing this, the app will tell you and offer to download it for you from Microsoft.

dankdronedownloader's Issues

Mavic 2 -Pro / Zoom Gimbal Issue

I downloaded Gimbal calibration firmware from application.

In this application 01.00.0780 is showing on list ARB2 - But its not ARB2. Its ARB1

So, it coudt be work on ARB2 motherboard. We can not flashing.

If device is ARB1 we are using 01.00.0703 . It is working.. But we will update device. After that problem is coming again.

Do you have ARB2 version of Gimbal Calibration Firmware ?

Thanks

1. How do I view the file I had downloaded? And also, 2. Why won't Drone Hacks detect my drone?

So I have a DJI Mini 2. I want to fix the Gimbal by recalibrating it using update Ver. 20.06.0200

so that I could perhaps actually fix my irritating gimbal warning (40011 err code)

I want to get to use the file I had downloaded and access it. I don't know where the file is. I also want Drone-Hacks.com to detect my drone.
Still looks like this:

Perhaps someone who is wiser may be able to assist me in my lack of experience issue.
Thanks!

Agras support

What Program would I use to flash firmware to a DJI T-30 drone and controller?

Missing DJI RC-N1 firmware for Mini 2 and Air 2S

I cannot find the firmware for the DJI RC-N1 controller for the Mini 2 and Air 2S.
However, I see there are several "Remote" firmware versions for the Air 2 (without the S).
Is there a way to retrieve it?
What happens if I only update the drone firmware and leave a very old controller firmware?
Thank you.

Good day, installed the program, downloaded the firmware. Uploaded by DUMLdorev3.2. But I can't start flashing. Tell me how to do it correctly. I am a newbie. Thanks for the answer.

How to debug "No one DDD server active." error

I can reach the online app at http://dankdronedownloader.com/DDD2/app/ and http://dankdronedownloader.co.uk/DDD2/app/ but when I run the Windows executable I'm getting the "No one DDD server active." error.

I've tried opening the firewall to the .exe and even shutting off the firewall entirely.

Can you tell me what site is being hit or what criteria is checked for this error?

Am I correct in presuming that if the online app is running that the necessary files/data/sites should be accessible with the windows .exe? (I would feel silly debugging the client-side, if there actually is a server-side issue!)

Thanks in advance!

File mislabeled or download did not match selection

I saw something about this somewhere in the notes I think, for 2.0. But tried downloading firmware for phantom 4 advanced 1.18 and ended up getting 1.28. Im new to this so am I doing something wrong?

DDD not opening on Windows 10 64bit v22H2,

hello sir, can anyone help solve the problem of DDD not opening on Windows 10 64bit v22H2, I have installed the 803 runtime, but it still won't open when I double click the application....

Security Concerns

The credentials aren't well protected, and though you have rssh, I think there may be ways to escalate privs on the hosting infrastructure. Maybe setting an environment variable, or uploading a .so to be used as a cipher, or by messing with .htaccess--- I don't have any malicious intent but I poked around a bit, you being the hacker type I figure you wouldn't mind... I might be able to help further lock things down if you care to reach out to me

In China I can‘t use this software

Hello, I'm in China. When I use the software it said 'DankDroneDownloader no ddd server'. Can I fix this problem by myself? Or it is the server problem? I remember that this software can be used in China in the old version. Perhaps you don't have enough money to keep the service in China.
If you do have any difficulties in this area, I'd be happy to help you. In anyway, it is my hope that I can use the software. Without this precious things, I will feel very inconvenient. Thank you!
