Q1 How to get the latest camera firmware? Does the SDK support firmware upgrades?

Please visit https://www.insta360.com/download to download the appropriate firmware for your camera. The mobile SDK allows users to transfer the firmware file to the camera via Wi-Fi. The desktop SDK allows users to transfer the firmware file to the camera via a USB cable, but the camera should be in Android mode for the SDK to connect to the camera properly. Only supports X4 and X5.
