Hello guys/ladies... I have a problem. I had a perfectly great flying P3 pro... Kept getting a weird notification that would come and go to upgrade RC and MC. Well silly me I clicked update. I now have video feed but no control of gimbal or ANYTHING and the **** thing flashes signal lost... So. I tried hooking up to my brand new NEVER flown P3 pro that is my back up. I got the same message. Now I refused the update. I have no connection at all. I have tried to link up controllers left and rite with no success. The remote I refused the upgrade on turns on. After 10 seconds it starts a beep...beep...beep... Very loud. I have tried to force a manual upgrade with a usb stick.. Hooking it to my 3rd known good P3...and everything. It will not link? Any ideas on what I can do about fixing it? I have downgraded all the way to 1.3FW and one at a time up to 1.7beta. Nothing works? I have done each step 1000 times. I have been trying to figure this out since Friday cry emoticon I am at my wits end and no tech from DJI can figure out the problem?
