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 dual camera not working properly or producing poor images?
The Mi 5s Plus uses a unique dual camera system with color + monochrome sensors. Issues can be caused by:
- Software corruption (fixed by clean flash)
- Camera calibration data loss
- Physical damage to one or both sensors
- Lens alignment issues
A clean flash often resolves software-related camera problems. If issues persist, the camera module may need service.
Q2. What’s the difference between Mi 5s and Mi 5s Plus?
Key differences include:
- Size: 5.15″ vs 5.7″ display
- Camera: Single 12MP vs Dual 13MP system
- Fingerprint: Under-glass ultrasonic vs rear physical sensor
- Battery: 3200mAh vs 3800mAh
- Build: Metal unibody vs metal with plastic antenna lines
Their firmware is not compatible due to different hardware.
Q3. Can I upgrade to newer Android versions on my Mi 5s Plus?
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
These provide significantly better performance, security, and modern features compared to the stock Android 8.0.
Q4. Why is my touch screen sometimes unresponsive or erratic?
This is a known issue on some Mi 5s Plus units, often caused by:
- Software/driver issues (fixed by clean flash)
- Faulty digitizer
- Screen protector interference
- Moisture or physical damage
A clean flash can resolve software-related touch issues. If problems continue, the digitizer may need replacement.
Troubleshooting (Natrium-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. - Dual camera not working together: If only one camera works or monochrome mode is unavailable, this indicates driver or calibration issues. A clean flash usually restores full dual camera functionality.
- 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. - Poor battery life despite large capacity: The Snapdragon 821 and 5.7″ display can be power-hungry. If experiencing rapid drain: 1) Check battery health, 2) Clean flash to eliminate software issues, 3) Consider battery replacement if capacity has degraded significantly.
- Touch screen issues: If clean flash doesn’t resolve touch problems, try: 1) Removing screen protector, 2) Cleaning screen, 3) Testing in safe mode. Persistent issues likely indicate hardware failure requiring digitizer replacement.
