Recommended Custom ROMs

For users dealing with bloatware or seeking a smoother experience, the Xiaomi.eu ROM leverages the Redmi 6 Pro’s Snapdragon 625 for a refined MIUI experience. The sakura variant has decent custom ROM support due to its shared hardware with other Xiaomi devices.

  • Xiaomi.eu ROM: V12.0.1.0.PDICNXM Based on Android 9.0 – Offers a lightweight, optimized MIUI experience with Google services.
  • LineageOS: Check LineageOS or XDA Forums for unofficial builds like LineageOS 17.1 (Android 10), providing a clean Android experience with improved performance. Note that Android One users may need to flash MIUI first before custom ROMs.

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. Note for Mi A2 Lite users: If your device runs Android One, you may need to flash MIUI firmware first to switch to MIUI-based ROMs.

Method 1: The Fastboot Method (Official Stock ROMs)

  1. Unzip the Firmware: Extract the .tgz file using 7-Zip to obtain a folder with an “images” subfolder and flash scripts.
  2. Launch Mi Flash Tool: Open the Mi Flash Tool with administrator privileges on your Windows PC.
  3. Enter Fastboot Mode: Power off your Redmi 6 Pro, then press and hold Volume Down + Power until the Fastboot logo appears.
  4. Connect to PC: Plug your phone into your PC using the USB cable.
  5. Load Firmware: In Mi Flash Tool, click “select” and choose the extracted firmware folder. Click “refresh” to detect your device.
  6. Choose Flash Option: Select “clean all” for a complete reset (recommended for stability). Avoid “clean all and lock” unless you’re certain of the ROM’s region compatibility.
  7. Start Flashing: Click “flash” and wait 5-10 minutes. Do not disconnect the phone.

Troubleshooting Tip: If Mi Flash Tool fails to detect your Redmi 6 Pro, try reinstalling the Xiaomi USB Drivers or switching to a USB 2.0 port for better connectivity.

Method 2: The Recovery Method (Custom ROMs)

  1. Install TWRP: Ensure TWRP is installed using the provided TWRP image or a newer version from TWRP’s official site.
  2. Transfer ROM: Copy the .zip ROM file (e.g., Xiaomi.eu) to your phone’s internal storage or an SD card.
  3. Boot into Recovery: Power off your phone, then press Volume Up + Power until the TWRP logo appears.
  4. Wipe Data: In TWRP, go to “Wipe” > “Advanced Wipe” and select Dalvik/ART Cache, Cache, and Data. Swipe to confirm.
  5. Install ROM: Return to the main menu, tap “Install,” select the .zip file, and swipe to flash.
  6. Reboot: Reboot to system after installation completes.

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 Redmi or Mi logo. Once booted, follow the setup wizard and restore your data from your backup.

Device-Specific Q&A for the Redmi 6 Pro / Mi A2 Lite (sakura)

  • Q1: Why does my Redmi 6 Pro experience system lag? A: System lag can result from bloatware or heavy apps taxing the Snapdragon 625. Flashing the latest India ROM (V12.0.4.0) or the Xiaomi.eu ROM can improve responsiveness.
  • Q2: How can I fix battery drain on my Redmi 6 Pro? A: Battery drain may stem from background processes or outdated firmware on the 4000mAh battery.

  • Q3: Will the Redmi 6 Pro receive Android 10 or newer? A: The Redmi 6 Pro / Mi A2 Lite is officially capped at Android 9.0 with MIUI 12 (or Android 10 for Android One on Mi A2 Lite). For Android 10 or newer on MIUI devices, consider custom ROMs like LineageOS 17.1, available for sakura on XDA.
  • Q4: I flashed a ROM for cereus or cactus on my sakura device and it’s bricked. What do I do?

Seek help on XDA Forums if issues persist.
  • Q5: I have the Mi A2 Lite with Android One. Can I flash these MIUI ROMs? A: Yes, but you must first unlock the bootloader and flash TWRP, then install an MIUI Fastboot ROM (e.g., V12.0.4.0.PDMMIXM) using Mi Flash Tool to switch from Android One to MIUI. Follow XDA guides for detailed steps.
