A: Yes — official firmware from the manufacturer is generally safe when you match your device's exact model number and region. Flashing the wrong region or modified firmware can cause issues.
A: Mi MIX 2S China firmware is flashed using MiFlash. See the step-by-step guide above for the full procedure.
A: Some devices allow downgrading, others have anti-rollback protection that blocks it. Check the version-specific notes on each ROM page, or your model's community forum, before attempting a downgrade.
A: First, verify the firmware matches your exact model code (e.g. SM-S938B for Samsung, or the CPH-number for OPPO). Reinstall the manufacturer's USB drivers, use a rear USB 2.0 port directly on your PC, and retry. The troubleshooting box above the FAQ covers the most common failure modes.
