Now, open the command prompt as an administrator and run the following two commands: "JointCoarse" first, followed by "LinearHall". Wait for each command to finish executing.

You will then need to locate your python.exe file. The location may vary, but an example path is provided: "C:\Users\"your username"\AppData\Local\Programs\Python\Python37-32\python.exe".

Once you have located the python.exe file, run the following two commands in the command prompt, replacing "your COM port" with the specific COM port number for your Spark:

> C:\Users\"your username"\AppData\Local\Programs\Python\Python37-32\python.exe comm_og_service_tool.py "your COM port" -vv SPARK GimbalCalib JointCoarse

> C:\Users\"your username"\AppData\Local\Programs\Python\Python37-32\python.exe comm_og_service_tool.py "your COM port" -vv SPARK GimbalCalib LinearHall

Finally, turn off your Spark and unplug the USB cable.

It is important to note that some users have reported issues with the calibration process, particularly with the JointCoarse command. If you encounter any errors, ensure that your drone is on and connected to the correct COM port. Check that your command format is correct and that you have installed all the necessary software and files.

Additionally, some users have suggested that the calibration process may not be necessary when only replacing the camera module, as the gimbal housing remains the same.

If you continue to experience issues, it may be helpful to refer to YouTube videos and forums for troubleshooting tips and alternative methods.
