Hello, Been browsing the forums for a few days however have had little luck in finding a solution so here goes: My drone crashed a couple of weeks ago which led to a slightly bent roll-arm but everything else was fine, including camera, signal to app, body etc. I replaced the roll-arm a few days back, as well as the flex cable coz the original was looking a little raggedy, and now I get no video feed on my device and the aircraft thinks it's a Pro and not Advanced, with no option to change the aircraft in the DJI Go App. I've made sure all cables are seated properly - gimbal boots up just fine. I can fly the quad but have no video feed on my HTC M9. Another side issue is the new firmware upgrade. The aircraft isn't creating a text file however it is creating two BIN files : UserSetting and CalibrationData. The gimbal lights will flash red/green like it's trying to upgrade but after a while it just flashes green. And there's no beeping sound during the upgrade like there normally would. Any help is appreciated. Thanks.
