Is your Huawei Mate 10 Pro BLA-L09 stuck at the logo screen, in bootloop, or showing signs of a dead boot? Whether your phone crashed during an update or became unresponsive after flashing, this guide will help you restore it using the official flash tool and the right firmware.
When to Flash Your Huawei Mate 10 Pro
- Device stuck on Huawei boot logo (bootloop)
- FRP lock issue (requires official firmware)
- After flashing wrong build and phone not booting
- Blank screen or fastboot mode only
Before flashing, make sure to match the exact build and region code (e.g. C432, C10, C721) to avoid compatibility problems.
Tools You'll Need
- Firmware: Download for your specific model below
- Flash Tool: Huawei Multi-Download Tool or third-party Kirin flashing utility
- Drivers: Huawei USB Drivers (ADB + COM)
- Test Point: Only if the phone is not entering fastboot or is hard bricked
Step-by-Step Flashing Instructions
- Power off your phone and connect it to the PC in fastboot or EDL mode (use test point if needed).
- Install and open the flash tool.
- Load the correct firmware for your region (matching build number).
- Click Start and wait for the process to complete.
- Once done, disconnect and reboot the phone.
Post-Flash Checklist
- Factory reset if stuck in a bootloop after flash
- Check baseband/IMEI — if missing, you may need to reflash board firmware
- Ensure correct regional build was used
Troubleshooting Flashing Issues
- Device not detected: Try reinstalling USB drivers or change cable
- Flashing fails at 5% or 99%: Likely a region mismatch or corrupted firmware
- No display: Use test point and flash board firmware version
Disclaimer: Flashing firmware or modifying system software is risky. Only proceed if you understand the process. Using the wrong firmware can brick your device permanently. IMEI or network-related changes may be illegal in some countries — proceed at your own discretion for lawful recovery only.
