There are plenty of website guiding you all on how to setup XiaoYi Home Smart Camera or even how to troubleshoot it if the camera you bough were manufacture after November 2015. As for camera manufactured after November 2015, there is some kind of chip embedded in it and if you would have update the firmware on a camera made for China, you will then unable to use it as the camera will give you a message 'This camera cannot be used outside China" and it will shut down by itself and the only way to fix this is to flash back to old firmware.
I bought a camera online, China version and it was working perfectly and was in English version as well as having the latest online firmware. And then I got another few camera and try to setup it all over again with a new MI account so I reset all the camera and BANG I am having problem connecting the camera to my WIFI, I thought it could be my MI account issues or firmware issues which I doubt it very much because all the camera are not having the error message.
So I thought to just flash one of the camera firmware and BANG.... it really failed to work. So I keep thinking what is the problem then I end up found the reason behind it. The very first time I can't connect to the WiFi is because I have all the camera all power up which is a big mistake.
Then I end up reset all my camera and power off and reboot my router and setup one camera at a time and it works but I screw up one good camera which I am trying to fix it now.
CONCLUSION
- Camera bought before the November 2015 can be updated to latest firmware
- Latest camera manufactured date can't update to latest firmware else you will kill it.
- Power up the camera one by one to set it up
Use only China version apps on your phone.
