To update your One X2 firmware you will need to perform the following:
Temporarily download/install the Insta360 mobile application named, "Insta 360- GO 2, One X2, One R,X" onto your mobile device.
Turn on your camera.
Open the Insta360 App and follow the on-screen instructions to connect your camera to the application via wifi.
Within the Insta360 App, navigate to "Settings."
Scroll down to “Firmware Version.”
Select “Firmware Version” to start the firmware update process.
*Note: If you are able to click on "Firmware Version," then an update is needed. If this is not visible, then it is up to date and no update is needed.
Select the yellow button, "Start to Download," and wait for it to download completely.
Then, select the yellow button, "Upload Firmware File to Camera," and wait for it to download completely (on the camera, the touch screen will turn black and the light should be blue during this process).
The camera's firmware is now up-to-date!
**IMPORTANT** Please delete the Insta360 app from your mobile device (this can interfere with the functionality of the OpenSpace app).
*Please ensure the camera's battery has more than 10% remaining.
*Please do not take out the battery or the SD card while updating.
*Please set the camera touchscreen to "Never Sleep" & keep the screen on during the firmware upgrade.
