However, the elephant in the room was the software. Due to the ongoing US sanctions, Huawei's shift away from Google Mobile Services (GMS) left many users struggling with Huawei Mobile Services (HMS) and the AppGallery.

For tech enthusiasts and power users who bought the MatePad 10.4 in 2021, the question wasn’t if to modify the device, but how. The hunt for a Huawei MatePad 10.4 custom ROM became a holy grail for those wanting to restore Google apps, debloat the system, or flash a clean version of Android.

This article explores the history, the risks, the available builds, and the current state of custom development for the Huawei MatePad 10.4 (2021).

Step-by-Step: Flashing a GSI ROM (2021 Method)

Assuming you have an unlocked bootloader and Fastboot access.

Pre-requisites:

The Process:

  1. Enable Developer Options: Tap "Build Number" 7 times. Enable "OEM Unlocking" and "USB Debugging".
  2. Reboot to Fastboot: adb reboot bootloader.
  3. Unlock (One time): fastboot oem unlock [YourCode] (If you have a code; otherwise, the test-point method bypasses this).
  4. Flash the GSI:
    • Delete the logical system partition: fastboot delete-logical-partition system_a (or system_b).
    • Flash the image: fastboot flash system your-rom.img.
    • Erase userdata: fastboot -w.
  5. Reboot: fastboot reboot.

Post-Flash (2021 specific fix):
The first boot takes 5-10 minutes. On LineageOS GSI, you must flash a "Huawei audio fix" via fastboot, otherwise speakers output static noise.
