The Huawei Mate 20 (codename "Hima" or "HMA") was a flagship device powered by the Kirin 980. While a powerful phone, it was known for some significant issues. Early models famously suffered from a "green screen" problem (a hardware fault with LG-made screens). As the device aged, users also reported significant battery drain after updating to EMUI 10 or higher, as well as general system lag and app freezes. Flashing an official stock firmware is the most reliable way to fix software-related bugs, unbrick a device stuck in a bootloop, or perform a clean installation to restore performance.

‼️ CRITICAL WARNING: READ BEFORE FLASHING ‼️
  • Complex Files: The files below are for the Huawei Mate 20, but they are for different models, regions, and, most importantly, different flashing methods. Flashing the wrong file or using the wrong method will hard-brick your device.
  • MODEL & REGION: You MUST flash the firmware that matches your exact model (e.g., HMA-L29) and region (e.g., C432).
  • CHINA vs. GLOBAL (NO GOOGLE APPS):
    • HMA-Lxx (L09, L29) models are Global and have Google Play Services.
    • HMA-AL00 (C00) models are for China. Their firmware DOES NOT HAVE GOOGLE PLAY SERVICES. Flashing a Chinese ROM on a Global phone will remove all Google apps.
  • FILE TYPE: There are THREEdifferent file types here.
    • Dload.zip: Standard packages for the user-friendly SD Card method (Method 1).
    • Advanced .rar / .zip: These are factory ROMs (like the C432E8R1P5 files) that are NOT dload files. They are flashed with PC tools (Method 2).
    • Board Software / HMT: Factory files for EXPERTS ONLY to repair a dead phone (dead boot) via PC (Method 2, Test Point).
Note: Flashing firmware will not fix the "green screen" issue which is a hardware defect.

➡️ How to Flash the Firmware​

Please use the method that corresponds to the file you downloaded.

Method 1: Huawei dload (for ...Dload.zip files)​

Use this method for all files listed in Section 1.
  1. Step 1: Download and extract the correct firmware .zip file for your model (e.g., `Huawei_Mate_20_Hima-L29CA...Dload.zip`).
  2. Step 2: Inside the extracted files, locate the `dload` folder (which contains a large `update.app` file).
  3. Step 3: Copy the entire `dload` folder to the root directory of your Nano Memory (NM) card or USB OTG drive.
  4. Step 4: Power off your Huawei Mate 20 completely.
  5. Step 5: Insert the NM card/OTG. Press and hold all three buttons: Volume Up + Volume Down + Power. Keep holding until the EMUI update screen appears. The phone will automatically find the file and start flashing.
For a complete, detailed guide, please refer to the full step-by-step tutorial: How to Unbrick and Flash Huawei Firmware (dload method).


Method 2: Advanced PC Flash (for HMT, Board, .rar files)​

‼️ WARNING: EXPERTS ONLY ‼️
All files in Section 2 are NOT for the dload method. They are factory ROMs that require special PC software (like HMT, as hinted in the filenames) and expert knowledge. They are used for advanced unbricking and repair (e.g., IMEI). Board Software specifically requires you to open the phone and short test points on the motherboard to force a connection. This is for experts only.


🛑 Disclaimer: This process is performed at your own risk. We are not responsible for any data loss, bricked devices, or damage. Flashing will not fix the hardware "green screen" issue. Flashing a Chinese (AL00) ROM on a Global (L09/L29) phone will remove Google Play Services and may cause a brick. Flashing Board Software is extremely dangerous for non-experts. If you have any problems, please drop a comment on the thread.​
