: Generally the most popular custom ROM for Android devices, but it is often unavailable for newer Huawei tablets due to the locked bootloader.

If you're still determined to find a specific build, I recommend checking the Huawei MatePad 10.4 forum on XDA Developers, which is the only reputable place where real developers share experimental projects.

You can make the stock HarmonyOS/EMUI feel like a "clean" custom ROM by removing pre-installed apps:

Attempting to force-flash a generic or corrupted system image onto a locked Huawei tablet will permanently brick the device, turning your tablet into an expensive paperweight. Safe Alternatives: How to Get Google Apps Without Flashing

The bootloader is the gatekeeper software that loads the operating system. Unlocking it is an absolute prerequisite for flashing any custom software or gaining root access.

: Some paid services (like Global Unlocking or HCU Client) claim to provide unlock codes for a fee, but these rarely support newer Kirin processors found in the MatePad 10.4

Installing a custom ROM on a Huawei MatePad 10.4 is extremely difficult because Huawei officially stopped providing bootloader unlock codes in 2018. Without an unlocked bootloader, you cannot "crack" the device to install third-party firmware like LineageOS.

These apps create a "virtual environment" to run Google Maps, YouTube, and the Play Store.
