How to troubleshoot firmware upgrade failure on the Xiaomi Smart Camera C100?

Firmware update failures on the Xiaomi Smart Camera C100 are caused by unstable network conditions or temporary server issues. Please try again in a different network environment. If your network is stable, simply try again at a later time.
Note:
1. Avoid using public Wi-Fi networks that have unstable or restricted connections;
2. Keep the device powered on and connected to the network during the entire upgrade process;
3. If the upgrade fails repeatedly, try restarting both the device and your router before attempting again;
4. Make sure the Mi Home/Xiaomi Home APP is updated to the latest version;
5. Avoid interrupting the upgrade by disconnecting power or network; doing so can cause firmware corruption.
