Assuming you have managed to unlock your bootloader, the availability of ROMs depends heavily on which specific variant of the MatePad 10.4 you own (e.g., BAH-W09, BAH-L09, etc.).
1. AOSP / GSI (Generic System Images) Because device-specific development is thin on the ground, many users turn to GSI ROMs (Project Treble). This allows you to run a generic version of Android (like Pixel Experience or LineageOS) on the device.
2. Ported HarmonyOS / EMUI Oddly enough, some "custom ROMs" for Huawei devices are actually ported versions of newer firmware from different regions or newer devices. These are popular because they retain HarmonyOS features (which are genuinely good for multitasking) but might patch in microG (Google services emulation) or debloat the system heavily.
3. Googlefier Solutions (The "Soft" ROM) For the 90% of users who cannot unlock their bootloaders, the community has developed "Googlefier" scripts.
Installing a custom ROM on the Huawei MatePad 10.4 is extremely difficult because Huawei officially stopped providing bootloader unlock codes in July 2018. Without an unlocked bootloader, you cannot natively flash third-party operating systems like LineageOS or Pixel Experience.
If your goal is to access Google apps or a different user experience, here is a breakdown of the current state of "custom" software for this tablet. 1. The Bootloader Barrier
The most critical hurdle is the locked bootloader. Unlike some other Android manufacturers, Huawei does not offer a legitimate way to unlock their newer devices. Third-Party Services: Some paid third-party services (like DC-Unlocker huawei matepad 10.4 custom rom
) occasionally support specific Huawei models for a fee, but support for the MatePad 10.4 is rare and inconsistent Warranty Warning:
Attempting to force an unlock via third-party exploits can permanently "brick" (disable) your tablet and will void your warranty. 2. Alternatives to Custom ROMs
Since traditional custom ROMs are largely unavailable for this device, users typically turn to virtual environments to run Google Mobile Services (GMS) or "de-Google" their experience. Virtual Machines (GBox / GSpace / VMOS): Applications like
create a virtual environment that mimics a Google-certified device. This allows you to install the Google Play Store and run apps like YouTube or Google Maps.
can run an entire secondary Android OS (e.g., Android 7.1) as an app on top of HarmonyOS/EMUI. Alternative App Stores: Aurora Store:
A privacy-focused "client" for the Google Play Store that allows you to download apps without a Google account. Petal Search: Assuming you have managed to unlock your bootloader,

If you want a cleaner "Stock Android" feel without a custom ROM, you can remove Huawei's pre-installed bloatware using ADB (Android Debug Bridge) on a computer.
The Problem: If you own a Huawei MatePad 10.4 (whether the standard, 6GB, or Kirin 810/820 variants), you likely bought it for its stunning hardware. The screen is crisp, the speakers are loud, and the battery life is impressive. But there’s one major drawback: the software.
Due to the US trade ban, most MatePad 10.4 models launched without Google Mobile Services (GMS) and run on older versions of EMUI with no clear path to HarmonyOS updates in global regions. This has left many users asking the same question: “Can I flash a Custom ROM to get Android 12, 13, or even 14 on this tablet?”
Here is the reality of the custom ROM scene for the Huawei MatePad 10.4.
If you own the Chinese variant (BAH3-W09) or a global unit running pure HarmonyOS, installing Google Play Store is a hacky process involving backup apps and "Googlefier." A custom ROM based on AOSP (Android Open Source Project) restores native GMS support, allowing seamless access to YouTube, Gmail, Drive, and the Play Store without workarounds. Installing a custom ROM on the Huawei MatePad 10
There have been attempts to port OpenHarmony (open-source version of HarmonyOS) and a faulty LineageOS 18.1 (Android 11) specifically for BAH3-W09. These are unstable—cameras often break, and deep sleep fails, draining battery overnight.
Verdict: For the average user, GSI ROMs are your only realistic custom ROM choice.
Before you start searching for downloads, you need to understand the hardware situation. The MatePad 10.4 is powered by the Kirin chipset. Unlike Snapdragon devices where unlocking the bootloader is relatively straightforward, Huawei devices are notoriously difficult to modify.
The Hard Truth: For the MatePad 10.4 (codenames usually Annie, Bach, or MatePad depending on the region), there is no official LineageOS, Pixel Experience, or crDroid build.
Because Huawei stopped providing bootloader unlock codes years ago, developers cannot easily port AOSP-based ROMs to this specific tablet. If you search YouTube or shady websites claiming to have "Android 13 for MatePad," be very careful—these are often clickbait or malware-laden "custom ROMs" that are just skins overlaid on your existing firmware.
