Hisilicon Kirin 710 Flash Tool Best -
No. SP Flash Tool is exclusively for MediaTek chips. Using it on a Kirin 710 will permanently short the eMMC controller. Stick to IDT or HCU.
For devices powered by the HiSilicon Kirin 710—such as the Huawei P30 Lite, Honor 10 Lite, and Huawei Y9 (2019)—finding a reliable flash tool is essential for firmware updates, downgrading software, or recovering from a "bootloop". Because Kirin chipsets are proprietary to Huawei, standard flashing tools used for Qualcomm or MediaTek devices generally won't work. Top HiSilicon Kirin 710 Flash Tools
Choosing the "best" tool depends on whether you need a professional-grade solution or a free community-based utility.
SigmaKey / Sigma Plus: Widely regarded as the most powerful professional solution for Kirin 710 devices. It supports Board (factory) flash files and original Update.app files. Its standout feature is Software Testpoint, which allows you to put the device into "HUAWEI USB COM 1.0" factory mode without disassembling the phone to find hardware pins.
Smart-Clip2: Often used interchangeably with Sigma software, Smart-Clip2 provides comprehensive support for the Kirin 710/710F/710A series. It is specifically designed for complex operations like enabling downgrades and writing OEM INFO to fix "Chip is damaged" errors.
Huawei Unlock Tool (HUT): A popular community-developed option available on platforms like GitHub. Recent beta versions have added a dedicated Kirin/Hisi partition flash tool and a GPT reader for better partition management during the flashing process.
Hydra Tool: A versatile dongle-based tool frequently used for FRP (Factory Reset Protection) removal and user data flashing on the P30 Lite and other Kirin 710 models.
UnlockTool: A digital license-based software that is highly effective for modern Huawei devices. It is particularly noted for its ability to remove FRP on Kirin 710F UFS variants. Flashing Procedures and Modes
Flashing a Kirin 710 device typically requires specific connection modes to be recognized by your PC:
Factory Mode (HUAWEI USB COM 1.0): This is the deepest level of access, often required for unbricking. You can reach this via a Hardware Testpoint (shorting specific pins on the motherboard) or via Software Testpoint in tools like SigmaKey.
Fastboot Mode: Used for flashing individual partitions like recovery or system if the bootloader is unlocked.
Upgrade Mode / SD Update: Used for official firmware updates or downgrades using Update.app files. Tools like Smart-Clip2 can automate this by selecting the appropriate SD_update file type for Android 10 and higher. Important Precautions
Firmware Compatibility: Always ensure you use the same or a higher firmware version unless using a tool specifically designed to "Enable Downgrade".
Backup: Flashing usually wipes all data. Professional tools often offer a "Backup chip data" feature to save critical network and IMEI information before you begin.
Drivers: Ensure you have the Huawei USB COM 1.0 drivers installed so your PC can communicate with the Kirin chipset in its low-level factory state.

Why it’s the best for Kirin 710:
Pros:
Cons:
Best for: Professional mobile repair businesses.
Most people have never heard of IDT. That’s your first clue it’s special. IDT doesn't care about your phone's software corruption. It bypasses the bootloader, the recovery partition, even the battery controller. It speaks directly to the Kirin 710's Primary Boot ROM—the first millionth of a second of code that runs before anything else.
Is Fastboot a "flash tool"? Yes—the purest one. And on a Kirin 710 with an unlocked bootloader, it’s poetry. You don't need proprietary boxes or leaked DA files. You just type:
fastboot flash system system.img
But here’s the interesting part: Most Kirin 710 phones shipped with locked bootloaders and Huawei stopped issuing unlock codes in 2018. So, the "best" tool becomes a social engineering challenge. The real flash tool is a paid third-party unlock service (like HCU or DC-Unlocker) that generates a bootloader code from the phone's IMEI. When choosing a flash tool, consider the following factors:
Determining the "best" flash tool for the HiSilicon Kirin 710 depends entirely on the state of the device:
Final Recommendation: For the average user, avoid "SP Flash Tool" or cracked flashing boxes, as these carry a high risk of corrupting the NVRAM (losing IMEI/Baseband). Always attempt eRecovery first, followed by HiSuite PC mode. Only use Fastboot tools if you have confirmed the bootloader is unlocked.
Disclaimer: Flashing firmware carries the risk of voiding warranties and permanently damaging the device. This paper is for educational purposes. Always verify model numbers (e.g., FIG-LX1 vs SNE-LX1) before proceeding.

Abstract The HiSilicon Kirin 710 (and 710F/A variants) represents a pivotal mid-range System on Chip (SoC) utilized extensively in Huawei and Honor devices (e.g., Mate 20 Lite, Honor 8X, P Smart). Due to the cessation of official bootloader unlock codes by Huawei and the complex partition structure of the device, flashing firmware requires specialized tools capable of handling the eMMC/UFS protocol handshake and proprietary Huawei loaders. This paper analyzes the hardware-software interface of the Kirin 710, evaluates the efficacy of existing flashing tools, and determines the optimal solution for device restoration and firmware modification.
The primary barrier for the Kirin 710 is the locked bootloader. Unlike older Huawei devices, newer firmware locks the bootloader, preventing the use of Fastboot flashing tools. If the device is locked and cannot boot into eRecovery, software tools are largely ineffective. The "Best" solution here is often hardware repair (eMMC/UFS programming) or utilizing authorized dealer accounts (like SigmaKey or Chimera Tool) which can bypass this in specific modes.
