No video, gimbal status N/A, can't read SD, no camera control

Were you ever able to get it up and working? I'm gathering that I might need a new main core board, but I cannot find one at a reasonable price.

I never have gotten mine fixed. And I too am thinking I need a core board and can't find one reasonably priced.

I never have gotten mine fixed. And I too am thinking I need a core board and can't find one reasonably priced.

I came here looking for a solution to the same issue mentioned by you and others . gimbal status showing Disconnected , no control over gimbal, video transmission only lasting 4 minutes . And all the other issues mentioned above . Including SD card not showing or being accessible , camera showing N/A , no iso etc….
2 Hours later ….
I’m happy to report I got my mavic pro back up and running ( no test flight yet ) at least in the sense off all the issues I was facing and that were mentioned here.
*****SOLUTION*****
***make sure battery is 50% or better
*** windows computer worked best

Connect you Mavic Pro to you computer ( I have a Mac but couldn’t get the program to install on Big Sur ) windows computer worked best for me. Installed DJI Assistant 2 ( be aware of the difference in the software read the bottom of the supported models page to ensure you DL the correct file ) once installed connect your Mavic Pro to your computer , making sure you drone battery is at least 50% once the computer sees the drone the program will launch the status of your drone and also a list of all the firmwares you’ve installed on it, and also the current version your drone is using . It will also have either a Update,downgrade, or refresh button next to each firmware version you can possible use .. In my case I just hit the refresh button next to the current firmware .
It proceeded to update and got to 100% but failed the first time . I simply rebooted the drone and started the procedure again and it went thru the update process getting to 100% on three different progress lines . When it was done I unplugged the usb from the computer , plugged it right back in and then the program said update successful .
Unplugged from Computer , then connected my phone to remote and turned on drone . And Boooom my baby was back to life . Granted I had to adjust the iso and camera settings to get a picture on screen but it worked , full gimbal control , camera options and video transmission , gimbal status-normal .
The SD wasn’t being recognized but I just switched in a new card and formatted it and boom !! Back in the air I go .
Anyways sorry for the long post but I felt this could help others . Blue skies to all
