IDT 20 uses XML configuration files (often referred to as Board Software or factory firmware) to partition and write data to the phone's storage.

Install the Huawei USB drivers on a Windows PC (Windows 10 is recommended). Disable Driver Signature Enforcement if the drivers fail to initialize.

Flashing the firmware of a similar model onto your device (e.g., flashing a Pro model ROM onto a standard model) will corrupt the device baseboard and IMEI. Always verify your exact model number.

: The phone is typically connected to the PC while in a specialized state (often triggered by a hardware "test point" on the motherboard) to be recognized as "HUAWEI USB COM 1.0".

Download the appropriate standard commercial EMUI firmware update for your exact model variant. Flash the update using standard SD-card dload methods, or via command-line fastboot tools, to rebuild user-facing Android applications, system security features, and localized modems. ⚠️ Safety Warning and Troubleshooting Common Errors 🔴 Red Screen / Error on XML Parsing

Remember: backup first, read twice, flash once.

Once the tool displays "Success" or "Download Complete," disconnect the device.

: The technician doesn't use a standard USB connection. They often have to trigger a "Test Point" on the phone's motherboard, physically short-circuiting two tiny gold pins to force the processor into a special "USB COM" mode.

Older versions (IDT 9, IDT 11, IDT 17) lacked support for newer file systems like (Extended Read-Only File System) and F2FS (Flash Friendly File System). IDT 20 was reverse-engineered to handle:

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.

A simpler, third-party alternative often used for automated detection and basic flashing of older Android-based Huawei models. 4. Risks and Technical Requirements

Click the "Browser" button and select the XML firmware file (e.g., a .xml file from your extracted board software folder). Connect Device (Testpoint): Turn off your phone and remove the back cover.

When you open IDT v20, you see a deceptively simple grid:
