Flashing Requirements
- Verify codename degas in fastboot with fastboot getvar product before flashing.
- Unlocked bootloader required for all fastboot ROMs; use official recovery/OTA on locked devices.
- Windows PC, Xiaomi USB drivers, Mi Flash Tool, reliable USB‑C cable and 15–20 GB free space.
- Back up data; “clean all” fastboot flashes wipe internal storage.
- If you updated and now see heat/drain, a clean flash can help stabilize HyperOS 2.
How to Flash the Firmware
- Download the correct degas_…_images_… TGZ for your region and extract it until the images folder and flash_all*.bat appear.
- Install Xiaomi USB drivers and open Mi Flash Tool; select the extracted firmware directory.
- Boot the phone into fastboot mode, connect via USB and click Refresh to confirm detection.
- Choose “clean all”, click Flash and wait for Mi Flash to report success; do not disconnect early.
- First boot may take longer as the system optimizes apps; monitor thermals for a day or two.
