I reinstalled my operating system, and in turn needed to redownload the DJI Phantom 1 assistant software, RC assistant, and driver. I was running version 1.08, but the only option I had was the 2.0 upgrade. I installed it, upgraded, and then lost the ability to calibrate X1. It either doesn't move, or when it does, won't traverse entirely. I started searching the forums, and found someone had placed a link to revert back to 1.08. So I followed through with that in hopes of fixing the gimble tilt issue. So far, no luck. I've tried the RC assistant as someone suggested, I've upgraded, the reverted, and all other options I can find here. Any suggestions?
