Hello DJI,

maybe this is a common problem that have been reported around the forum, but somewhat it's getting worst at this time,
below i have screenshot on my samsung galaxy tab (using dji go latest version) and phantom 3
I cannot sync my flight records at all, it's stuck on 98 - 99% and then "sync failed"

Sync Progress

Sync Failed

I've tried reinstalled & clear all app data on DJI folder, but it's still not synced

sync log folder i've found this:

DJI Synclog

Downloading DJIFlightRecord_2015xxxxxxxxxxx.txt...
Failed to downloadDJIFlightRecord---xx.txt. Error code:0. Back code: 255. Error Info: Timeout waiting for connection

i have stable internet connection (wifi & 4G), it seems the issues is not connection

Please help
Thanks

hi dji gamora, thank you for response.. yes i have try on another mobile devices, iphone 11, samsung galaxy tab a8 (s-pen), nokia 8, xiaomi blackshark, and problem still there, cannot finished sync records with same error

but, i've been workaround today that i have found a way to delete error flight records in DJI Server by placing a file named ".FlightDelete-email@gmail.com.tmp" on flightrecords folder


here's the step
Create a file with name .FlightDelete-youremail-.tmp, open with notepad, and insert the log error from previous log (my first post) :



Place that file in this folder :

Flightrecords folder

Try to sync again, and voila.. my flight logs back


Here's the sync log



And i noticed the footprints has been fixed, before i have china flag and some other flags (i never go there)
seems like my old flightlog in DJI Server has been corrupted (yes, it's old 2015xxx)
and i lost almost 100 flight times.. any chance that my flight log can recovered?

hopefully this step can help other user with same problem

Hi dji gamora,

it's okay to lose some of my flight logs, but for everyone asking, what caused the flight record to be damaged?  and i'm curious why my profile doesn't contain phantom icon / spark icon (i have two of them)  like everyone else, could you please add from forum back-end ? sorry for not related to the topic

thankyou

Hi, thank you for your raising this concern to us. With regards to the flight records, this concern was already been raised to our designated department and they are now looking into it. The drone icon will only appear on your Forum profile if you use the same email address that you used to activate the drone that you have. Therefore, if you purchase it 2nd hand it will not appear on your profile since it was activated on a different email. Hope this helps. Thank you!

I have a smart controller that does the same thing   only sync one of my flights

Hi, Rodnie. We have sent you a PM, please check. Thank you.

Hello DJI, I have mavic air 2, but still appearing Bug null:255. I've tried my samsung s22+ (android 13), app DJI drone and then rainbow. Nothing, cannot lift of the ground. Not a move with the propellers. Yesterday, I've tried Samsung with lower android and it finallly connected!! BUT still cannot lift the drone and still the same bug null:255. What can I do, what's wrong? Can you tell me? As I read, I'm not the only one, who's got the same problem and no reply of you. Thanx.

Hi there, we are sorry to know about this issue. May I ask if the drone has crashed or hard landing before? May I ask if the firmware and app versions are up to date? If not, please upgrade them to the latest version. If possible, please also test with another mobile device to see if it works.

EDIT: SOLVED in my case. The answer is that there is a THIRD, different app, that works for this particular drone. The app I needed for the Mini 2 SE drone is the "DJI Fly" app.

Hello,

I just got a new DJI Mini 2 SE drone.
In the "Go Fly" DJI Drone app it seems to connect to the drone. But when I try to fly I keep getting the null:255 error. I notice that the Mini 2 SE isn't one of the listed drones though, there is only "Mini 2" or "Mavic Mini SE".

I also installed the DJI GO 4 app from the website, but that doesn't seem to support the Mini 2 SE (it's not among the list of possible devices in Setup).

I used the Assistant 2 app to update the firmware of the drone, but that didn't help.
Please help.

Julian
