How to Flash Infinix Hot 12i X665B Stock ROM

Flashing stock ROM on the Infinix Hot 12i X665B requires SP Flash Tool, which works specifically with MediaTek-powered devices. The tool supports scatter-based firmware files, making it compatible with the X665B firmware packages.

Before starting, you need MediaTek USB VCOM drivers installed on your computer. These drivers enable communication between your device and the flashing tool during the process. Charge your battery to at least 50% and back up all personal data, as flashing erases everything on your device.

Download and extract the firmware package on your computer. You’ll find the flash file, SP Flash Tool, drivers, and installation manual inside. Install the USB drivers if not already present on your system. Subsequently, open SP Flash Tool and click “Scatter-Loading” to select the scatter file from your extracted firmware folder.

Power off your device completely with the battery inside. Connect it to your computer via USB cable while holding the Volume Down or Volume Up button. Click the “Download” button in SP Flash Tool to begin flashing. The tool will automatically detect your device and start transferring the firmware.

A green circle appears when flashing completes successfully, indicating your Infinix X665B has been restored to stock firmware.Conclusion
