Crucial Warning: Match the firmware to your exact model (KE6 or KE6j) before downloading. Cross-flashing between models can prevent the phone from booting. Some files circulating online are mislabelled as Spark 6 Air but contain firmware for different Tecno devices.

Compatibility & Bootloader Notes
Flashing stock firmware through SP Flash Tool in MediaTek BROM mode does not require an unlocked bootloader. However, the MT6761 chipset enforces Secure Boot SLA authentication, so an MTK Auth Bypass utility must be run before SP Flash Tool can connect.
Preparation checklist for Tecno Spark 6 Air
- Verify your exact model code (KE6 or KE6j) under Settings > About phone.
- Install MediaTek USB VCOM and LibUSB filter drivers on your PC.
- Launch an MTK Auth Bypass utility to disable MT6761 SLA security before connecting.
- Ensure battery charge is above 30% before initiating flashing.
- Back up personal files — flashing erases user data.
