Hello,

Last week I bought a Spark drone. I charged the battery, started the drone, installed the app, installed the DJI assistent 2 on my desktop, connected my android to the drone, updated the firmware. All things seemed fine, till I got a messgae saying that the "Aircraft is locked". I tried many things so far, but nothing helped. I read all kind of forum treads, downgraded my firmware and updated it again, reinstalled the app. I'm starting to become a bit desperate. I haven't used the drone for a single second and it seems that there is a lack of information about how to solve this problem. I hope someone can help me out in here. Thanks in advance.

I also used "factory reset settings" and I calibrated the IMU and compass.

Have you updated the precise fly database within the app for DJI GEO to know your location?

When Im connected to the drone it says that I need to connect to internet and when Im connected to internet is says that I need connection with the drone. The current version is 01.00.01.09, so I guess that is the latest version.

Btw, my drone is unlocked thanks to the duml dore program, but somehow it doesn't feel like the right solution.

OK - that is the latest FW version. Have a look at the DJI tutorial on the whole set up process for linking and updating FW and see if that helps.

Riks, may I know if you are using Android mobile device? If yes, could you please refer to my post in 7# and provide us more info? Thank you very much.

With google and 'DJI Spark locked', you could find a video with the chance for a solution.

Do you by any chance have an RC as well? If you do scan the controller not the aircraft.

Hi all, our engineers are working on this issue in high priority, if you have exported the log, please kindly upload to Dropbox or Google Drive and post the link here.
It would be much appreciated if an IOS mobile device can be used to have a try? Please connect the phone to the network, enter DJI Go 4 APP, if there is pop-up window about the Fly Safe Database upgrade, please update to the latest version and then switch to Android mobile phone to see if the issue persists. Thank you very much.

https://www.apkmirror.com/apk/dj ... droid-apk-download/ use this as the current apk is broken. I had the same error and reverted to this version and was able to fly.

Hi my google drive link to my log data is below.

I am using android version 7 on Huawei mate 8.

Try the above link.uninstall ur current Dji Go 4 app and install the version from the link. It has worked for me and a few ppl who have experienced the same problem.

are you all on 4.2.12?
Did you use the official release in Google Play, or one from somewhere else e.g. apkmirror?

Fixit Now i have same problem, i need to get a old app.

Hi All,
Thanks for your patience. Our engineers have been aware of the issue and will optimize in the next APP version. At this moment, please switch to IOS version or previous Android APP to figure this out.
Again, we sincerely apologize for the inconvenience. We'll release as long as the new version is ready. Appreciate your understanding.

DJI Go 4 downgrade to 4.1.15 helps I spent 3 nights in firmeare upgrades and downgrades. But nothing... Only DJI Go downgrade soles this.

Thanks a lot - that solved my problem! I tried everthing, but only this downgrade to a previous DJI GO Software Version helped and i can fly again.  

I'm so glad I just found this post, brought a new spark at the weekend and haven't flown it yet as I keep getting "aircraft locked" I'm on Android as well on a Samsung galaxy S8, kept getting 4 solid red lights and that's it, funny thing is if I reinstalled the firmware I get the 2 red lights and 2 flashing lights but as soon as I reboot it's back to 4 red again.

Sorry for the late response. This issue has been figured out in 4.2.14, please update to the latest version and check again.

4.2.14 works ok
