FAQs
Q1: Is the Mi MIX 2 still usable in 2025?
As a daily driver, it's for enthusiasts. The Snapdragon 835 is still capable for many modern apps, but its camera and battery are dated by today's standards. Its primary appeal is its beautiful, iconic design. It serves wonderfully as a secondary device.
Q2: Can I get Android 10, 11, or newer on the Mi MIX 2?
Not officially. However, thanks to its flagship Snapdragon processor, the chiron has a strong and active custom ROM community on forums like XDA. You can find many stable, unofficial builds of much newer Android versions there, giving the phone a surprisingly long life.
Q3: How do I take a selfie with the camera on the bottom?
This is the iconic design quirk of the MIX series. To take a selfie, you simply rotate the phone 180 degrees (upside down). The camera software automatically adjusts the orientation for you.
Q4: Is the Xiaomi.eu ROM better than the official Global ROM?
For most enthusiasts, yes. Although they are both based on MIUI 12.0, the Xiaomi.eu version has no bloatware or ads and often includes extra features and optimizations from the China ROM base, providing a more streamlined experience.

Troubleshooting & Common Errors
- Bootloop after flashing a custom ROM: You must use the "Format Data" option in TWRP before flashing. This is required to remove the encryption from the stock ROM and is the most common reason for a failed boot.
- Mi Flash Tool shows a "sahara" or "xbl" error: This is a common error on older flagship devices. It can indicate a bad USB connection or a driver issue. Try a different USB 2.0 port and cable, and run the tool as an administrator. In very rare cases, it can signify a hardware fault.
- "The system has been destroyed": This is a standard Xiaomi error for a failed boot. It is not a hardware problem. Simply force the phone back into Fastboot mode (Power + Vol Down) and flash the stock firmware again.
- SafetyNet / Banking App Issues on Xiaomi.eu: An unlocked bootloader and custom ROM can sometimes cause these apps to fail security checks. Advanced users can often solve this by installing Magisk and using modules designed to hide the phone's modified state.
