A significant technical analysis by researchers at Black Hat and Tasznik Labs outlines the three-stage boot process common to these chipsets: hisilicon kirin 710 flash tool

Stage 1 (BootROM): The root of trust that creates a secure chain. It includes a USB Download Mode which has been the subject of vulnerability research.

Stage 2 (Xloader): Often split into multiple steps (Xloader and UCE), this component is signed but not always encrypted in Kirin 710 models, allowing it to be retrieved from firmware updates for analysis.

Stage 3 (Fastboot): Unlike many Android devices where Fastboot runs in normal world EL1, Huawei's Fastboot often runs in EL3, making it responsible for loading not just the kernel but also TrustZone firmware. 2. Flashing Mechanisms and Tools Flashing the

generally requires specific service software that can interface with the hardware's unique "Factory Mode."

This is historically done via a physical Testpoint (shorting a specific point on the motherboard to ground), though modern tools now offer a "Software Testpoint" that achieves this without disassembly.

involve flashing "Board" firmware to temporarily enable fastboot oem unlock commands, which can circumvent the standard factory locks.

The Ultimate Guide to the Hisilicon Kirin 710 Flash Tool: Unbrick, Repair, and Restore Firmware

Introduction

The Hisilicon Kirin 710 is a workhorse of a processor. Found in millions of mid-range smartphones—including the Huawei P Smart, Honor 8X, Honor 10 Lite, and Mate 20 Lite—this 12nm chipset delivers reliable performance. However, no matter how stable the hardware, software issues are inevitable. Boot loops, forgotten passwords, system corruption, and failed over-the-air (OTA) updates are common nightmares for Kirin 710 device owners.

Enter the Hisilicon Kirin 710 Flash Tool. Unlike generic flashing utilities, this specialized software is designed to communicate with Huawei’s proprietary download mode. In this extensive guide, we will explore everything you need to know: what the tool is, official vs. third-party options, step-by-step flashing instructions, driver setup, and troubleshooting common errors. The Ultimate Guide to the Hisilicon Kirin 710

Understanding the Challenge

Unlike other manufacturers that use generic flashing protocols, HiSilicon chips (Kirin series) utilize a proprietary bootloader and communication protocol.

Phase 1 (Fastboot/Recovery): Used for official OTA updates or partial firmware changes.
Phase 2 (Emergency Download/Bootloader): Used when the phone is "hard bricked." This allows the computer to detect the device as a generic USB device (often showing as USB\VID_12D1&PID_3609 in Device Manager) to load a bootloader.

Because Huawei locked down their bootloaders in recent years, finding a tool that works universally is difficult. Below are the primary tools used for the Kirin 710.

Important Notes

No SP Flash Tool: Kirin chips do not work with MediaTek's SP Flash Tool.
No QFIL: Kirin uses proprietary protocol, not Qualcomm Sahara/Firehose.
Vendor partition: Kirin 710 uses A-only partition layout with vendor image.
Signature check: All flashed images must be signed by Huawei.

3. Secure Digital Storage (SD) Card Method

This is the safest official method provided by Huawei. It utilizes the dload folder mechanism.

Best for: Rolling back versions (downgrading) or fixing soft bricks.
Limitations: Requires a working recovery mode. It will not work if the bootloader is corrupted.

✅ 2.1 Boot Loop After OTA Update

Your phone restarts endlessly, showing the “Honor” or “Huawei” logo. Recovery mode works, but wiping cache/factory reset fails. Flashing a full stock ROM is the only fix.

Step 2: Install the COM Port Driver

Open Device Manager.
Right-click the unknown "USB Serial" device.
Manually install the "Huawei, LdUsbVcom" driver. It will assign a COM port number (e.g., COM5).

Step 1: Enter Download Mode (COM 1.0)

Method A (Software): If the phone shows "Fastboot & Rescue mode," run the command: fastboot oem enter_download.
Method B (Hardware): For hard bricks, disassemble the phone, locate the test points near the eMMC chip. Short them while connecting USB. The PC will detect "Huawei COM 1.0."

Step 1 – Enter BootROM Download Mode (COM 1.0)

Power off the device completely.
For Kirin 710, you typically need to short the test point (two tiny contacts on the motherboard) OR hold the Volume Down button while connecting USB.
Connect USB to PC. Device Manager should show “Huawei USB COM 1.0 (COMx)”.
