⚠️ Essential Pre-Flash Checklist
Flashing can lead to errors if not done correctly. Complete this checklist to ensure a smooth process. All data will be wiped, so a backup is critical.
- ✅ Full Data Backup: Save photos, contacts, and files to Mi Cloud, Google Drive, or a PC to prevent data loss.
- ✅ Charged Battery: Ensure your Mi 2/2S has at least 60% battery to avoid interruptions during flashing.

- ✅ Original USB Cable: Use a high-quality USB cable (Micro-USB for Mi 2/2S) for a stable connection to your PC.
- ✅ Unlocked Bootloader: Flashing requires an unlocked bootloader. Use the official Mi Unlock Tool (expect a 7-15 day waiting period).
- ✅ Required Software: Install the latest Mi Flash Tool and Xiaomi USB Drivers.
Understanding the Firmware: Types and Regions
Selecting the correct firmware is crucial to avoid bricking your Mi 2/2S (aries). The aries codename applies to both the Mi 2 and Mi 2S, which share similar hardware (Snapdragon S4 Pro for Mi 2, Snapdragon 600 for Mi 2S), but ensure the ROM matches your specific model for full compatibility.
- Fastboot ROM (.tgz): A full factory image for Mi Flash Tool, ideal for unbricking or reverting to stock MIUI.
- Recovery ROM (.zip): Used with custom recoveries like TWRP for installing custom ROMs like Xiaomi.eu.
- Region Codes:
- CNEK: China version, optimized for local networks but may lack Google Play services.
- MIEK: Global version with Google services and multi-language support.
- CNDL/EUXM: Xiaomi.eu version, a debloated MIUI ROM with Google services and multi-language support.

TWRP Recovery for Mi 2/2S (aries)
To flash custom ROMs or recovery ROMs via TWRP, install the TWRP custom recovery specific to the Mi 2/2S (aries).
- TWRP Recovery: TWRP-3.7.0_9-0-aries – Official TWRP image from TWRP’s site, recommended for the latest compatibility. For updates or older versions, check TWRP’s official site or XDA Forums.
How to Install TWRP:
- Download the TWRP .img file and rename it to
recovery.img. - Boot your Mi 2/2S into Fastboot mode (Volume Down + Power).
- Connect to your PC and open a command prompt.
- Flash TWRP by running:
fastboot flash recovery recovery.img. - Boot into recovery:
fastboot boot recovery.img.
Warning: Do not use a TWRP image for other devices (e.g., libra or aqua), as it will brick your aries device. Verify that the TWRP version is aries-specific.
Recommended Custom ROMs
Custom ROM support for the Mi 2/2S (aries) is limited due to its older Snapdragon S4 Pro/600 chipsets, which have reduced community development compared to newer devices. The Xiaomi.eu ROM is the primary option for a refined MIUI experience.
- Xiaomi.eu ROM: V8.2.1.0.LXACNDL Based on Android 5.0 – Offers a lightweight, optimized MIUI experience with Google services.
- LineageOS: Check LineageOS or XDA Forums for unofficial builds like LineageOS 14.1 (Android 7.1). Support is limited, and features like the camera may not work fully due to the older chipsets.
How to Flash: Step-by-Step Instructions
Choose the flashing method based on your firmware type: Fastboot for official .tgz files or Recovery for custom .zip files.
Method 1: The Fastboot Method (Official Stock ROMs)
- Unzip the Firmware: Extract the .tgz file using 7-Zip to obtain a folder with an “images” subfolder and flash scripts.

- Start Flashing: Click “flash” and wait 5-10 minutes. Do not disconnect the phone.
Troubleshooting Tip: If Mi Flash Tool fails to detect your Mi 2/2S, try reinstalling the Xiaomi USB Drivers or switching to a USB 2.0 port for better connectivity.

After the Flash: First Boot and Setup
The first boot after flashing may take 10-15 minutes as the system initializes. Don’t interrupt if it seems stuck on the Mi logo. Once booted, follow the setup wizard and restore your data from your backup.
Device-Specific Q&A for the Mi 2/2S (aries)
- Q1: Why does my Mi 2/2S experience system lag? A: System lag can result from bloatware or heavy apps taxing the Snapdragon S4 Pro/600. Flashing the latest Global ROM (V9.2.2.0) or the Xiaomi.eu ROM can improve responsiveness.
- Q2: How can I fix battery drain on my Mi 2/2S? A: Battery drain may stem from background processes or outdated firmware on the 2000mAh battery. Flashing a clean stock ROM or the debloated Xiaomi.eu ROM can optimize power efficiency.
- Q3: Will the Mi 2/2S receive Android 6 or newer? A: The aries variant is officially capped at Android 5.0 with MIUI 9. Unofficial builds like LineageOS 14.1 (Android 7.1) may be available on XDA, but support is limited due to the older chipsets, with potential issues in features like the camera.
- Q4: I flashed a ROM for libra or aqua on my aries device and it’s bricked. What do I do? A: If your device is in EDL mode (Qualcomm HS-USB QDLoader 9008), use Mi Flash Tool with the correct aries Fastboot ROM (e.g., V9.2.2.0.LXAMIEK). Select “clean all” to restore the device. Seek help on XDA Forums if issues persist.
