I just got my P3P back from repair. Had an encounter with a tree and the Gimbal arm was bend. When I booted the Phantom upI wanted to make sure that I was up to date on FW and recalibrate the IMU. Upgraded to Firmware v1.9.60. - but once I was back up, I get "No image transmission". I see a lot of other threads with people having the same issue - and I have been able to sum it up to these possibilities based on the threads: 1) Firmware bug 2) Firmware bug but in combination with certain types of SD cards, works with some SD cards, and not with others 3) Fried gimbal card due to heat during upgrade. Has anyone solved this by downgrading? Has DJI acknowledged a FW bug? Or is this only solved by repair?
