No, for most users.
The Huawei MatePad 10.4 is a niche tablet. The development community is tiny compared to Samsung or Xiaomi tablets. Here is the honest truth about the “Huawei MatePad 104 custom rom cracked” search:
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. huawei matepad 104 custom rom cracked
Exploit sent.
The tablet vibrated. The screen flickered, then displayed a chaotic cascade of green debug text.
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. No, for most users
When the setup wizard appeared, Kael almost laughed. It asked him to connect to Wi-Fi. He did. Then he opened the terminal.
su
dmesg | grep -i "crack"
The kernel logs showed the truth: [TZ] Secure monitor bypassed. Custom init loaded.
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. Bootloader Unlocked
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:
“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.
End
If you successfully unlock the bootloader, you are not swimming in options like a Xiaomi or OnePlus device. The Kirin chipset has poor open-source documentation. However, a few niche projects exist:
