Ok, I think I messed up, I got a notice to upgrade firmware to new multispectral version for my P4P, I did, and now have no image transmission? I know my P4P is not multispectral version now....Oops! How do I downgrade back to previous firmware that was working fine?

Thanks for any advice

oh, and No I have not crashed it or had a hard landing....

Thanks.
i was able to get back to correct firmware on drone, but still having issues with image transmission? I did the drone calibration on the screen, and the camera worked, but it is not displaying on the tablet where it normally does? Radio signal quality is GOOD, everything else is working, the gimbal is controlled by controller, just no image coming back to controller/tablet.
Tied the usual, different batteries, different tablets...

we are on same page, i tried that, and even tried a second SD card, still same issue. Going to try another controller and then may see if a different radio channel is any help.

Check the Gimbal Ribbon cable for damage or disconnection !

replaced the whole gimbal unit/camera, and reloaded firmware, now image transmission works, but second issue I was having is worse, it keeps losing GPS signal, then it takes off and wont stop and hover. 3rd time I am lucky I was able to wrestle it back down and land, very scarey!
