Flashing Tool

This package looks like a MediaTek file; it is usually flashed with SP Flash Tool.

Important – Technical Use Only

- Install USB drivers on your PC before connecting the device.
- Always verify the model number, build number and hardware version before flashing.
- Ensure the device battery is sufficiently charged (recommended at least 50%).
