Troubleshooting (Blade A7 2020 Specific)
- “BROM ERROR: S-CHIP HASH DOES NOT MATCH”: You’re trying to flash the wrong firmware variant. Ensure you have correct firmware for your device’s specific memory configuration (2GB/32GB vs 3GB/64GB).
- SP Flash Tool not detecting device: This is usually a driver issue. Install the correct MediaTek USB drivers and try different USB ports. Ensure device is in download mode.
- IMEI lost after flashing: MediaTek devices store IMEI in NVRAM. You’ll need to restore IMEI using SN Write Tool or similar utilities if backup is unavailable.
- Performance issues after flash: Ensure you flashed the correct variant. The 2GB and 3GB versions have different memory optimizations.
- Storage recognition problems: If storage size appears wrong, you may have flashed the wrong variant. Flash the correct firmware for your hardware configuration.
- Battery life concerns: The 4000mAh battery should provide good endurance. If experiencing rapid drain, calibrate battery after flashing by fully charging and discharging.
