Matepad 104 Custom Rom 2021: Huawei

Sites like Ministry of Solutions or Global Unlock Solutions offered remote bootloader unlock for ~$25-50 USD. They used leaked Huawei engineering tokens. Success rate in 2021: 70%. Many users reported bricked devices.

By 2021, Huawei’s HarmonyOS (a fork of Android) was rolling out, but many international users preferred the familiarity of AOSP (Android Open Source Project) with full GMS support. The stock EMUI/HarmonyOS experience, while smooth, had three major flaws driving users to custom development:

You cannot flash a custom ROM without an unlocked bootloader. In 2021, Huawei had officially closed all unlocking portals. The community fragmented into three camps:

For the average user, the answer in 2021 was no. The risk of bricking the device, combined with the cost of unlocking the bootloader and the instability of early GSI ports, made sticking to stock EMUI/HarmonyOS the smarter choice. Sites like Ministry of Solutions or Global Unlock

However, for the tech enthusiast, the MatePad 10.4 remained a fascinating device. It highlighted the resilience of the developer community in the face of locked-down hardware. Even without a plethora of dedicated Custom ROMs, the device survived 2021 as a capable media consumption tool, proving that great hardware could often outlast software limitations.

A comparison done by a Russian reviewer ("RomHacker Pro") in November 2021: A custom ROM promised a pure, unencumbered Android

| Metric | Stock HarmonyOS 2.0 | LineageOS 17.1 (GSI) | |----------------------|---------------------|-----------------------| | Geekbench 5 (Single) | 640 | 635 | | Geekbench 5 (Multi) | 2450 | 2440 | | Storage Read | 780 MB/s | 810 MB/s | | RAM Management | Aggressive (kills background) | Standard (better for multitasking) | | Google Play Battery Drain | 2% / hr (idle) | 4% / hr (idle due to broken deep sleep) |

Takeaway: Performance was nearly identical. The real benefit was software freedom, not speed.

A unique 2021 development was a custom update.app file that bypassed the bootloader unlock entirely. This was a Frankenstein ROM combining AOSP frameworks with Kirin drivers. While risky, it was the only option for users who updated to HarmonyOS and lost the ability to unlock the bootloader.
