Hello everyone! I’m having trouble with my second-hand Phantom 4 Pro (P4P) drone. Despite hoping to fix it, I’ve encountered several issues. I’m using a Phantom 4 Pro with a GL300F controller, and while I can connect the Go 4 app and see sensor feedback, there’s no video feed, SD card recognition, or GPS signal. Additionally, the camera buttons (record, image, camera angle, menu, C1, C2) are unresponsive. I attempted a firmware update, but it got stuck at 64%, and the drone turned off and on with red lights on the arms. If anyone has faced this issue and found a solution, please let me know. Otherwise, I might consider selling it for parts.
