How to Flash via Fastboot (Mi Flash Tool)
- Unlock your bootloader using the official Mi Unlock tool. This is a mandatory first step.
- Extract the downloaded .tgz firmware file to a folder on your PC.
- Open Mi Flash Tool. Click Select and choose the extracted ROM folder.
- With your phone powered off, boot into Fastboot mode (Hold Volume Down + Power). Connect it to the PC.
- In Mi Flash Tool, choose the clean all option. Avoid “clean all and lock” unless you are absolutely certain you are flashing the correct stock ROM for your device’s original region.
- Click Flash and wait for the process to complete. The first boot may take 5-10 minutes.
FAQs
Q1. Why is my proximity sensor not working during calls?
The Mi Mix uses an ultrasonic proximity sensor instead of traditional infrared sensors. Issues can be caused by:
- Software/driver corruption (fixed by clean flash)
- Screen protector interfering with ultrasonic waves
- Physical damage to the sensor array
- Calibration data loss
A clean flash often resolves software-related sensor issues. Remove screen protectors for testing.
Q2. How does the piezoelectric ceramic earpiece work and why is it quiet?
Instead of a traditional earpiece, the Mi Mix uses:
- Piezoelectric ceramic driver that vibrates the entire display
Sound is transmitted through bone conduction and display vibrations
If volume is low:
- Check sound settings and disable audio enhancements
- Clean the speaker grille
- Ensure display is not obstructed
- A clean flash can reset audio drivers
Q3. Can I upgrade to newer Android versions on my Mi Mix?
Yes! The Snapdragon 821 has excellent custom ROM support:
- LineageOS 16.0 (Android 9)
- LineageOS 17.1 (Android 10)
- LineageOS 18.1 (Android 11)
- Some Android 12 builds
However, custom ROMs may have issues with the unique ultrasonic sensors and piezoelectric earpiece.
Q4. Why is my ceramic back easily scratched despite being durable?
The ceramic body is hard and resistant to cracking but:
- Can develop micro-scratches from daily wear
- Shows fingerprints easily
- Requires careful handling despite durability
Use the included protective case or a quality third-party case for daily protection.
Troubleshooting (Lithium-Specific)
- “Antirollback check error” in Mi Flash Tool: The device has Anti-Rollback (ARB) protection. You cannot flash older ROM versions. Check your current ARB version with
fastboot getvar antiand ensure you’re flashing a ROM with the same or higher version number. - Proximity sensor not working during calls: First, ensure no screen protector is installed. Then try: 1) Clean flash to reset drivers, 2) Sensor calibration in hardware test mode (
*#*#6484#*#*), 3) Check for physical damage. - Device not detected in Fastboot mode: This is usually a driver issue. Install the latest ADB/fastboot drivers and try a different USB cable and port (preferably USB 2.0). Check device detection with
fastboot devicesin the command prompt. - Phone boots directly to Fastboot mode: This indicates a corrupted
boot.imgor system partition. Flash the complete stock ROM using the “clean all” option in Mi Flash Tool to restore all partitions. - Quiet earpiece during calls: Ensure: 1) Volume is maximized during calls, 2) No obstructions on display, 3) Audio settings are reset. A clean flash often improves piezoelectric driver performance.
- Accidental touch issues: The bezel-less design can cause accidental touches. Enable “Pocket mode” in Settings and consider using the included case which provides raised edges for better grip.
