It’s hard to believe that the Huawei Mate 8 (NXT) is now over five years old. Released in late 2015, this phablet was a powerhouse, boasting a massive 6-inch 1080p display and the legendary Kirin 950 chipset. For many, it was the perfect blend of battery life and performance.
But in 2021, the landscape for this device has changed. If you are still holding onto this tank of a phone (or dug it out of a drawer), here is what the Custom ROM scene looks like for the Mate 8 this year.
Assumptions: Your bootloader is unlocked, you have TWRP (3.5.0+) installed, and you have backed up your data.
The holy grail for the Mate 8 in 2021 is LineageOS 18.1. This is the lightest, fastest, and most modern OS available.
Users attempting to flash a ROM on the Mate 8 in 2021 faced a specific set of challenges:
The Bootloader Situation: By 2021, Huawei had stopped providing bootloader unlock codes officially. Users were required to use paid third-party services (usually costing $20-$50 USD) to obtain unlock codes, or use exploit
Maximizing Performance: Huawei Mate 8 Custom ROM Guide (2021 Edition)
Released in late 2015, the Huawei Mate 8 remains a solid piece of hardware due to its Kirin 950 chipset and massive 4,000mAh battery. However, official software support ended years ago, leaving many users stuck on Android 7.0 (Nougat) or the region-specific EMUI 8 update. In 2021, custom ROMs became the primary way to breathe new life into this legacy flagship. Why Install a Custom ROM in 2021?
For a device over five years old, custom ROMs provide several critical benefits:
Updated Security: Access to newer Android security patches that Huawei no longer provides.
Bloatware Removal: Official EMUI is often heavy; custom ROMs offer a cleaner, faster experience. Title: The老兵不死 (Old Soldier Never Dies): The State
Newer Android Versions: Unofficial builds can bring Android 8, 9, or even 10 to a device otherwise stuck in the past. Top Custom ROMs for Huawei Mate 8 in 2021
While development for the Mate 8 has slowed, several reliable projects remained active or accessible for users in 2021:
LineageOS: The gold standard for stability and longevity. Unofficial builds of LineageOS (often version 15.1 or 16.0) were popular choices for daily drivers.
Resurrection Remix: Known for extreme customization, this ROM combines features from LineageOS and SlimROMs. It was often distributed for the Mate 8 via the OpenKirin Project.
OpenKirin Project ROMs: This group specialized in Kirin-based devices, offering stable builds of OmniROM, LineageOS, and Resurrection Remix that were easier to flash on Huawei hardware.
Havoc-OS: For users seeking a modern UI, Havoc-OS (often Android 9 or 10 based) provided a "Pixel-like" experience with additional performance tweaks. Essential Requirements for Flashing Before you begin, ensure you have the following: Huawei Mate 8 32GB - Gray - Unlocked - Back Market

In 2021, the Huawei Mate 8 was considered a legacy device, being roughly five to six years old. Despite its age, the device retained a niche but active developer community, primarily due to its robust hardware (Kirin 950) and decent battery life. However, the custom ROM scene for this device in 2021 was defined by a split between "Legacy" Android 10 ROMs and emerging "GSIs" (Generic System Images) for Android 11 and beyond.
The biggest hurdle for users in 2021 was the Hardware DRM (Widevine) issue and the lack of official support from major ROM developers (like LineageOS) who had dropped support for the device in previous years.
The Mate 8 (NXT-AL10, NXT-L29) originally shipped with Android 6.0 (Marshmallow) and received an official update to Android 7.0 (Nougat). By 2021, no Android 8+ official updates existed. Custom ROMs like LineageOS, OpenKirin’s OmniROM, and Resurrection Remix offered potential upgrades, but Huawei’s 2018 decision to stop providing bootloader unlock codes created a critical barrier.
Surprisingly, yes. The Kirin 950 was ahead of its time. On a custom ROM like LineageOS 17.1, the Mate 8 flies. Without the heavy EMUI skin bloat, the phone feels snappy for web browsing and social media.
The 4000mAh battery is the star of the show. Even after 5+ years of charge cycles, users on custom ROMs report significantly better battery life compared to the stock EMUI, thanks to the optimizations in newer Android versions (Doze mode improvements).
