I'm kinda confused about new and old apps, firmware and compatibility. I had intended to wait until the dust cleared to update to V2 (firmware) so I waited 'till last Sunday to update. Coincidental with my upgrade to V2, I somehow ended up with V3, and I guess an updated app on my phone too. Now my P2V, which used to be wonderfully stable, wanders around a bit and the only way I get an image on my phone is to set it to the lowest image quality. I have Phantom_2_Installer_v1.08.exe and Phantom_2_Installer_v2.00.exe still alive and well in the downloads on my computer. I have downloaded DJI_VISION_V1.0.38.apk and DJI_VISION_V1.0.32.apk to my computer. I want to get back to where I used to be before the updates. Can I simply attach my P2V to my computer an run an earlier version? And if so which one? How do I get rid of the new app and put an older one back? Which one? What is compatible with what? Thanks for any and all assistance. A curse on DJI.
