Huawei Matepad 104 Custom Rom Install May 2026

The Huawei MatePad 10.4 custom ROM install scene is alive, but barely breathing. Unlike the golden era of the Nexus 7, this tablet fights you every step of the way. If you succeed, you will own one of the few unlocked Huawei tablets running stock Android. If you fail, you will have an expensive coaster.

Proceed with caution, backup your stock ROM via fastboot first, and keep a USB recovery cable handy.

Installing a custom ROM on a Huawei MatePad 10.4 is extremely difficult and generally considered impossible for most users. Huawei permanently stopped providing official bootloader unlock codes in July 2018, which is the essential first step for any ROM installation. Current State of Custom ROMs

Locked Bootloader: All modern Huawei tablets, including the MatePad 10.4 (2020 and 2022 editions), ship with a locked bootloader. Without an official code from Huawei, you cannot flash third-party recoveries like TWRP or ROMs like LineageOS.

Lack of Development: Because the bootloader is locked, there is virtually no developer community creating custom ROMs for this specific hardware. Most "guides" found online are either generic or refer to older Huawei devices from before 2018.

Hardware Barriers: The device uses proprietary HiSilicon Kirin chipsets (like the Kirin 810 or 820), for which source code is not publicly available, making it even harder to build functional ROMs even if the bootloader were unlocked. Potential (High-Risk) Alternatives

While official methods are dead, some advanced users attempt these high-risk workarounds: huawei matepad 104 custom rom install

Installing a custom ROM on the Huawei MatePad 10.4 (BAH3-W09 / BAH3-AL00) is extremely difficult and generally not recommended for the average user. Huawei ceased official bootloader unlocking in 2018, and this specific model (released in 2020) lacks the official tools and community support typical of other Android tablets. ⚠️ Critical Risks

Permanent Brick: There is no official way to recover a deeply "bricked" device if the bootloader process fails.

Warranty Void: Any attempt to modify system files or use third-party unlockers immediately voids your warranty.

Security Loss: Unlocking the bootloader disables security features like Widevine L1, meaning you may lose the ability to stream Netflix or Disney+ in HD. The "Bootloader" Barrier

To install a custom ROM, you must first unlock the bootloader. Since Huawei does not provide codes, you must use unofficial methods: 1. Paid Third-Party Services

Some users have had success with services like DC-Unlocker or Ministry of Solutions. Cost: Usually $4 to $30.

Requirement: You often need a PC and specific drivers (like HiSuite drivers) to detect the device in "Manufacturer Mode". 2. Hardware "Test Point" (Advanced) The Huawei MatePad 10

Tools like PotatoNV (open-source) can sometimes generate an unlock code for Kirin-based devices.

Method: Requires opening the tablet to short a "test point" on the motherboard while connecting to a PC.

Compatibility: Most versions of the MatePad 10.4 use the Kirin 810 or 710A; verify compatibility on the PotatoNV GitHub before attempting. Installation Overview (If Unlocked)

If you manage to obtain an unlock code, the process follows standard Android flashing procedures: Preparation

Back up everything: Unlocking the bootloader performs a factory reset.

ADB & Fastboot: Install these tools on your PC to communicate with the tablet.

Find a GSI: There are almost no dedicated custom ROMs for this tablet. Most users use Generic System Images (GSIs) from the OpenKirin project or Phhusson’s AOSP GSIs. Step-by-Step Go to Settings → phh Treble Settings →

Go to Settings → phh Treble Settings → Qualcomm features (even on Kirin) → Use alternate audio policy. Reboot.

Warning: Installing a custom ROM can void warranty, may brick the device, and will erase data. Proceed only if you accept these risks.

Q: Can I install LineageOS without unlocking the bootloader?
A: No. Absolutely impossible.

Q: Will a custom ROM fix the "Device is not Play Protect certified" error?
A: Yes, but you must manually register your device’s Android ID on Google’s website.

Q: My MatePad updated to HarmonyOS 4.0. Can I downgrade first?
A: Yes, using Huawei’s "HiSuite Proxy" to roll back to EMUI 10.1, but this is another 4-hour process.

Q: Does the stylus work on LineageOS?
A: Basic touch works, but palm rejection and pressure sensitivity are broken.

Because Huawei does not release full kernel sources for the MatePad 10.4, full-featured ROMs like LineageOS or Pixel Experience rarely exist. Instead, you use Project Treble GSI.

If you successfully unlock the bootloader, you have two options:
