Huawei Matepad 104 Custom Rom Cracked ★ Legit & Top-Rated

Because the MatePad 10.4 uses Project Treble, you can flash a “cracked” GSI. These are generic Android builds made for any device.

The Huawei MatePad 10.4, codenamed "Agassi," lay on the technician’s desk like a brick. To anyone else, it was a dead slab of glass and aluminum—a victim of HarmonyOS 4.2’s latest region-lock update. But to Kael, it was a sleeping giant.

Kael wasn’t a hacker for profit. He was a preservationist. When Huawei had locked the bootloader on the Agassi series two years ago, the global modding community had abandoned it. Official updates trickled in, each one tightening the screws, removing Google services, and forcing users into an ecosystem they hadn't chosen.

But Kael had a secret: a leaked engineering exploit, a sliver of code that exploited a long-patched vulnerability in the EMUI boot chain. For three months, he had worked in his cramped Shanghai apartment, reverse-engineering the trust zone. The goal wasn't just to root the tablet—it was to build a true custom ROM: LineageOS 22 with full microG support.

Tonight was the night.

Phase One: The Crack

He connected the MatePad to his laptop. The screen showed a progress bar—Downloading eRecovery...—a fake signal to Huawei’s servers. In reality, a custom script was overflowing a buffer in the USB controller.

Sweat dripped down his temple. One wrong hex value, and the eMMC chip would be hard-bricked.

Exploit sent.

The tablet vibrated. The screen flickered, then displayed a chaotic cascade of green debug text. huawei matepad 104 custom rom cracked

Bootloader Unlocked.
Sending vbmeta... Verified boot disabled.

Kael exhaled. The "crack" was real. He had bypassed Huawei’s signature checks without a paid bootloader code. He pushed the custom recovery—TWRP with a patched kernel.

Phase Two: The ROM

Flashing the ROM took seven minutes. He had named the build Agassi_Zero_v1.0. It was a clean, AOSP-based system with none of Huawei’s background telemetry. The GPU drivers were backported from a Kirin 990, giving the tablet better gaming performance than the stock OS ever had.

He rebooted.

The screen lit up. No "HarmonyOS" logo. No Huawei ID login. Just a crisp "LineageOS" boot animation—a stylized circle spinning freely.

When the setup wizard appeared, Kael almost laughed. It asked him to connect to Wi-Fi. He did. Then he opened the terminal.

The kernel logs showed the truth: [TZ] Secure monitor bypassed. Custom init loaded. Because the MatePad 10

He had done it. A 10.4-inch slate that was now his—not Huawei’s, not Google’s.

Phase Three: The Aftermath

He posted the ROM on a private forum under the handle "ZeroCool_Agassi." The title read: [STABLE] Huawei MatePad 10.4 (Agassi) – LineageOS 22 – Full Google-free + Performance tweaks. BOOTLOADER CRACK INCLUDED.

Within 48 hours, the post went viral in the underground. Thousands of frustrated MatePad owners—students in Brazil, devs in India, journalists in Turkey—downloaded the files. The crack was elegant: it used a hardware timing flaw in the Kirin 710A’s Trusted Execution Environment, something Huawei couldn't patch without a silicon recall.

Huawei’s security team issued a warning. Forums were scrubbed. But the internet is a hydra. Every time a link died, ten more appeared.

The Twist

One month later, Kael received an envelope. No return address. Inside was a single microSD card and a handwritten note: "Thank you. Now crack the MatePad Pro 13.2. We’ll pay."

He inserted the card. It contained a firmware dump from an unreleased Huawei device—and a diary log written by an engineer inside Huawei’s own R&D center. The engineer had deliberately left the timing flaw in the chipset, a silent act of rebellion against the company’s lockdown policies.

Kael smiled. He loaded up IDA Pro, opened the bootloader binary, and whispered to the dark screen: Bootloader Unlocked

“Let’s liberate another one.”

The MatePad 10.4 wasn't just cracked. It had become a ghost in the machine—a symbol that no walled garden is ever truly inescapable.

Disclaimer: This article is for educational and informational purposes only. Flashing custom ROMs, unlocking bootloaders, and using "cracked" software voids your warranty, carries the risk of bricking your device, and may violate Huawei’s terms of service. Additionally, "cracked" often refers to pirated software or workarounds for Huawei's locked ecosystem; this guide promotes community-developed solutions, not software piracy.

The Huawei MatePad 10.4 (models: BAH3-W09, BAH3-AL00, BAH4-W19) is a fantastic piece of hardware. It features a sharp 2K display, powerful (for its time) Kirin 710A or 820 chipset, and excellent battery life. However, it suffers from a massive software problem: HarmonyOS.

While HarmonyOS is technically Huawei’s successor to EMUI, for Western users and power users, it comes with deep restrictions. You lose Google Mobile Services (GMS), you are stuck with Huawei’s AppGallery (which lacks many global apps), and the bootloader is famously locked down.

This has led to a growing underground demand for a Huawei MatePad 104 custom ROM cracked—a version of AOSP (Android Open Source Project) or LineageOS that bypasses Huawei’s security to run pure Android with Google Play.

Custom ROMing a Huawei MatePad 10.4 is technically possible but highly model-dependent, with significant risks: difficulty unlocking, missing vendor drivers, DRM loss, stability and security concerns, and legal/warranty consequences. Prefer reputable community AOSP builds and thorough research over using ambiguous “cracked” ROMs.
