My P3P is bricked running iOS 9.3.1 and DJI Go 2.7.2. All worked prior to an auto app update to 2.7.2. Have tried a full restore, but the iCloud backup seems to be an iOS 9.3.1 install. Additionally, when you restore, it fails to install a previous version of the DJI Go app and goes off to install the latest version (due to Apple's App thining process). If anyone has an iTunes backup with DJI Go 2.7.1 in their Apps folder, could you let me know so I can try that. Cheers.
