The POCO X6 Pro 5G (global) and Redmi K70E (China), codename duchamp, are performance‑focused mid‑rangers powered by the MediaTek Dimensity 8300‑Ultra with a 6.67-inch 120Hz AMOLED and 5000mAh battery (POCO) plus 67W charging.

The firmware packages below (official Xiaomi fastboot images plus a Xiaomi.eu custom build) let you clean‑install and stabilize the system, fix bootloops/failed OTAs, and upgrade to Android 16 via HyperOS 3.0 where available.

Flashing Requirements
- Confirm device: In fastboot mode, run fastboot getvar product; it must return duchamp.
- Choose the correct region: CNXM (China), MIXM (Global), EUXM (EEA), RUXM (Russia), INXM (India), IDXM (Indonesia), TWXM (Taiwan).
- Unlocked bootloader: Required for fastboot ROMs and for Xiaomi.eu installs.
- PC setup: Windows PC, Xiaomi USB drivers, Xiaomi Mi Flash Tool, stable USB cable, 15–20GB free space.
- Backup and charge: Backup all data and charge above 60% because clean flashing wipes storage.
How to Flash the Firmware
Official fastboot ROMs (.tgz)
- Download the correct ROM from the table above and extract it until you see the images folder and flash_all*.bat.
- Install Xiaomi drivers and open Xiaomi Mi Flash Tool, then select the extracted ROM folder.
- Enter fastboot (Power + Volume Down), connect the phone, click “Refresh”.
- Select clean all and flash; do not disconnect until success.
- Reboot and let the phone settle; battery may look worse for 1–2 days after a major update while indexing finishes.
Xiaomi.eu DUCHAMP Android 16 ZIP
- Unlock bootloader and follow Xiaomi.eu’s install method for DUCHAMP (custom recovery/fastboot package, depending on release).
- Flash the ZIP, then perform a clean wipe if moving from stock to Xiaomi.eu to avoid conflicts.
- Boot and complete setup; test heat and drain with default settings first.
- Only then restore apps; avoid restoring full system backups if you’re troubleshooting drain.
- Update all apps and reboot once to stabilize services.
For step‑by‑step flashing with pictures and videos, use these guides: Xiaomi Mi Flash Tool tutorial (for the.tgz files above) and flash_all.bat guide (if you prefer scripts).
