Huawei Flash Tools IDT 20 (often referred to simply as IDT.exe or IDT 2.0) is a proprietary, low-level flashing utility designed specifically for Huawei devices powered by Kirin chipsets (and some older Qualcomm models). Unlike standard recovery methods (e.g., eRecovery or HiSuite), IDT bypasses the device’s normal bootloader and Android OS entirely. It communicates directly with the device’s download mode (also known as COM 1.0 or Huawei Upgrade Mode).
The "20" in the name typically refers to version 2.0 of the IDT tool—an update that brought improved stability, support for newer file systems (EROFS), and better error handling compared to the older IDT 1.x releases.
Warning: This process involves modifying system partitions. Flashing incorrect files can permanently damage your device. Proceed at your own risk.
Q: Does IDT 20 work on Huawei laptops (MateBook)?
No. It is strictly for Kirin-based phones/tablets.
Q: Can I unlock bootloader with IDT 20?
No. IDT does not handle unlock codes; use HCU or DC-Unlocker for that.
Q: My device is on HarmonyOS 2.0. Can I downgrade using IDT 20?
Only if you have a full EMUI service firmware with the same base version (e.g., HarmonyOS 2.0 → EMUI 12). Many devices block rollback via eRecovery; IDT may bypass this.
Q: The tool says “OPUS.secure boot enabled.”
That means your device has a locked bootloader with secure flash verification. You need to sign the firmware or use an official service XML—beyond the scope of leaked IDT.
Huawei’s transition to HiSilicon Kirin processors and EMUI (now HarmonyOS) introduced proprietary download modes (e.g., Huawei 1.0, 2.0, USB COM 1.0). Official flashing requires authorized Huawei service accounts. Third-party tools like IDT 20 fill a gap for independent repair shops. IDT 20 is part of the Infinity Dongle suite, specifically designed for Huawei devices.
Required:
Typical command sequence (via GUI):
Disclaimer: Flashing unauthorized firmware may void your warranty and carries a risk of permanent damage. Proceed only if you understand these risks.
Once loaded, you can write raw images to fastboot, kernel, recovery_ramdisk.
Pro trick: Check "Skip existing bad blocks" — Huawei eMMCs develop bad blocks near the boot area.
