I have a problem and hope you can help me.
I couldn’t find any assistance in the German forums. Suggestions ranged from “drop the drone” to “leave it in the fridge overnight.”
Here’s my problem:
After a longer break (around 1 year), I unpacked my Phantom 4 Pro and wanted to fly a bit (it worked perfectly fine when I packed it away!).
Right after powering it on, I got a message saying that the IMU needs to be calibrated. Since then, I’ve tried countless times, but unfortunately, without success.
The process itself takes much longer than I’m used to and gets interrupted in the first step with an error message (see photo).
I was doing a slow discharge of the batteries thinking ild pack it away to look into another time. After it sat there turned on with the motors off for a few hours it started working again.
This probably isn’t much help i know but it seemed to cure whatever the reason was for the drone not wanting to get back out of bed after a couple of years of sleeping in it’s case
Found this online for Error 50 - worth a try if you’ve not already done so
Key points about the error code 50:
Incorrect positioning:
The most likely cause is not following the exact positioning instructions given during the IMU calibration sequence on the app, which could be due to a slightly uneven surface or not placing the drone in the exact orientation required.
Storage position:
Storing the drone upside down can sometimes contribute to this error, so ensure it’s stored horizontally.
Calibration steps:
Carefully follow the on-screen instructions during calibration, making sure the drone is completely still and positioned as required.
How to troubleshoot:
Check the surface: Ensure you are calibrating on a perfectly flat surface.
Restart the drone: Try powering off and on again before attempting calibration.
Double-check positioning: Pay close attention to the positioning instructions on the screen during calibration.
Try different positions: If the error persists, try starting the calibration with the drone in a slightly different position, like on its back legs.
---- Understand a number of users have fixed the problem by laying the Phantom on its right side then performing the IMU calibration - may take a couple of attempts
Oh wow, I couldn’t find anything useful about the error message on German websites. I’ll try it out first thing tomorrow morning !
The table I’m working on is perfectly horizontal. I aligned it using a machinist’s level
@Schenkelspalter there are numerous forum threads on this topic (like this one) for different DJI drone models, and it seems the issue is consistently caused by storing the drone on its side or upside down.
As @Jhdee mentioned above, try starting the calibration with the drone lying on its side. If that doesn’t work, repeat the process with the other sides, and finally, try it upside down. One of these positions should allow the calibration to complete successfully.
Once calibrated, place the drone upright and perform another calibration following the usual positions shown in DJI GO 4.
