Contact the regional distributor or the government agency that issued the device (e.g., CG Government departments) for official recovery images.

Using the wrong firmware can "brick" your device (render it unbootable). Always verify that the firmware matches your specific build number found in Settings > About Tablet .

Open your flashing tool (e.g., SP Flash Tool) and select the Scatter file (for MTK) or the Flash.xml (for Intel) from the downloaded firmware folder.

Install the relevant USB drivers on your PC.
