A closed-source Chinese mod exists that keeps the Huawei Camera app intact. Do not use this unless you trust the developer implicitly – it often contains system-level telemetry and closed-source blobs.
With Huawei shifting entirely to HarmonyOS NEXT (which drops Android compatibility entirely), the chance of future custom ROMs for the P40 Pro is zero. The current GSI builds are maintained by only two developers on XDA (recognize users phhusson and AndyYan). When they stop, the P40 Pro custom ROM scene dies.
Instead of a full custom ROM, the practical solution for 95% of P40 Pro users is:
If you absolutely need full Google services and custom ROMs, sell the P40 Pro and buy a phone from a developer-friendly brand (Google Pixel, Nothing Phone, OnePlus, or Xiaomi with unlockable bootloaders). The P40 Pro’s hardware is extraordinary, but its software is a walled garden that cannot be truly escaped without breaking the very features that make it special.
Installing a custom ROM on the Huawei P40 Pro is significantly more challenging than on other Android devices because Huawei does not provide official bootloader unlock codes.
The following guide outlines the complex prerequisites and current methods available as of April 2026. ⚠️ Critical Warning Warranty Void
: Unlocking the bootloader and flashing custom software will permanently void your warranty. Risk of Bricking
: This process is highly technical; failure can permanently disable your device.
: All data will be wiped. Ensure you have a complete backup. Phase 1: Unlocking the Bootloader
The bootloader must be unlocked before you can flash any custom software. For the P40 Pro (Kirin 990 5G), official codes are unavailable, leaving only two main paths: 10 Best Custom ROMs for Android You Can Install - Beebom
The Huawei P40 Pro is a masterpiece of mobile engineering, boasting a Kirin 990 5G chipset and a legendary Leica camera system. However, for many users, the absence of Google Mobile Services (GMS) and the limitations of EMUI are significant hurdles. Installing a custom ROM can breathe new life into this hardware, offering a cleaner interface, better privacy controls, and sometimes, a gateway to Google apps.
This guide explores the current landscape of custom ROMs for the Huawei P40 Pro, the technical challenges involved, and how to decide if modding is right for you. The Elephant in the Room: The Locked Bootloader
Before diving into ROM selection, it is vital to understand the primary obstacle: Huawei stopped providing official bootloader unlock codes in 2018.
Bootloader Status: Most P40 Pro units ship with a locked bootloader.
Third-Party Services: To install a custom ROM, you must use paid third-party tools (like Ministry of Solutions or DC-Unlocker) or hardware test-point methods to unlock the device.
Risk Factor: Unlocking and flashing carries a high risk of bricking your device and voids your warranty. Top Custom ROM Options for Huawei P40 Pro
While the development scene for Kirin processors is smaller than for Snapdragon devices, several high-quality projects exist. 1. HarmonyOS (The Official "Custom" Path)
While technically an official OS, many global users "rebrand" their EMUI devices to the Chinese HarmonyOS version.
Pros: Better performance, smoother animations, and frequent security updates.
Cons: Still lacks native GMS; includes Chinese bloatware that requires debloating. 2. LineageOS (Unofficial Ports)
LineageOS is the gold standard for clean, bloat-free Android.
Pros: Extremely lightweight, privacy-focused, and offers a stock Android feel.
Cons: Often lacks full support for the P40 Pro’s complex camera array, leading to lower photo quality compared to EMUI. 3. OpenKirin Projects
The OpenKirin team has historically been the backbone of Huawei modding. They provide ROMs based on AOSP (Android Open Source Project).
Pros: Designed specifically for Kirin chipsets to ensure stability.
Cons: Development for newer EMUI versions (11 and 12) is slower due to Huawei's increased security. 4. GSI (Generic System Images)
Since the P40 Pro supports Project Treble, you can flash a GSI. Options: Pixel Experience, Resurrection Remix, or DotOS.
Pros: You can try the latest Android versions (Android 13 or 14).
Cons: "Bugs" are common, specifically with the in-display fingerprint sensor and face unlock. Benefits of Flashing a Custom ROM
🚀 Performance GainsRemoving EMUI’s heavy background processes can make the 90Hz display feel even more fluid and responsive.
🛡️ Privacy and ControlCustom ROMs often allow you to use MicroG (a lightweight replacement for GMS) or go completely "de-Googled" for maximum privacy. Custom Rom For Huawei P40 Pro
🎨 Aesthetic FreedomIf you dislike the "iOS-clone" look of EMUI, ROMs like Pixel Experience offer the clean, minimalist Material You design. Key Considerations Before You Start
If you decide to proceed with flashing, keep these requirements in mind: Backup Everything: Flashing wipes all internal storage.
Check Model Numbers: Ensure the ROM is compatible with your specific variant (e.g., ELS-NX9).
Camera Sacrifice: You will likely lose the advanced Leica post-processing features found in the stock EMUI camera app.
SafetyNet: Many banking apps and Netflix (in HD) may not work if the device fails SafetyNet certification. Is it worth it in 2024?
For most users, the best experience on a P40 Pro comes from debloating EMUI using ADB tools rather than a full ROM swap. However, if you are a power user who demands a specific Android skin or wants to experiment with GSI builds, the hardware remains capable of running modern software beautifully.

The Challenge
The Huawei P40 Pro, released in 2020, came with Android 10 out of the box. However, as with any device, the update cycle can be slow, and users may crave the latest Android version or prefer a specific user interface. Moreover, some users might want to remove bloatware or add custom features not available on the stock ROM. This is where custom ROMs come in.

As the P40 Pro X ROM evolves, Alex plans to:
The story of the custom ROM for Huawei P40 Pro showcases the power of community-driven development and the creativity of Android enthusiasts. With custom ROMs like P40 Pro X, users can breathe new life into their devices and enjoy a more personalized Android experience.
Finding a custom ROM for the Huawei P40 Pro in 2026 is a unique challenge because Huawei officially stopped providing bootloader unlock codes in 2018. While the hardware remains flagship-tier with its Kirin 990 5G chip and elite camera system, the software ecosystem is heavily locked down.
Instead of traditional custom ROMs like LineageOS, most P40 Pro enthusiasts now focus on rebranding to HarmonyOS or using advanced workarounds to restore Google services. The State of Custom ROMs for P40 Pro
Unlike devices from Xiaomi or Google, there is no vibrant "custom ROM" scene for the P40 Pro because developers cannot easily access the bootloader.
Official Support: There are no official builds of popular ROMs like Evolution X or LineageOS for this specific device.
Bootloader Status: Unlocking the bootloader typically requires third-party paid services or "test point" methods that involve opening the phone—neither of which is supported by Huawei.
The "Dark Web" Myth: While some forum users mention "dark web" ROMs, these are often just unverified experimental builds that carry high security risks. Top Alternatives: HarmonyOS and Google Services A closed-source Chinese mod exists that keeps the
Since traditional ROMs are largely unavailable, users have shifted to these high-impact software mods: 1. Converting to HarmonyOS (Rebranding)
Many global users convert their P40 Pro (ELS-NX9) to the Chinese version (ELS-AN00) to install HarmonyOS 4.2.
Why do it? HarmonyOS offers better performance, smoother animations, and more frequent updates than the global EMUI 12/14.
The Process: This usually involves using HiSuite Proxy to downgrade firmware to a specific version (like EMUI 10.1.0.131) before flashing the Chinese base. 2. Installing Google Mobile Services (GMS)
Because the P40 Pro launched without Google, the most sought-after "mod" is getting the Play Store to work.
Native GMS: Requires a specific downgrade to EMUI 10 followed by the "Googlefier" or "LZ Play" method.
MicroG: A modern, less invasive alternative that allows many Google apps and notifications to work on newer EMUI or HarmonyOS builds without full system modification. Huawei P40 Pro in 2025 (harmony os, google, etc)
Huawei P40 Pro is in a unique position regarding custom ROMs due to Huawei's strict policy of not providing bootloader unlock codes since 2018. This makes installing traditional custom ROMs extremely difficult for most users. The Custom ROM Situation
While a standard "Custom ROM" ecosystem like you'd find for Pixel or Xiaomi devices doesn't officially exist for the , there are alternative paths: Generic System Images (GSIs): Since the
launched with Android 10, it supports Project Treble. This allows you to flash Generic System Images (GSIs) like LineageOS or Evolution X.
Feature Focus: These provide a "clean" Android experience (AOSP) and can bypass some of the EMUI/HarmonyOS restrictions.
Caveats: You still need an unlocked bootloader to flash them. Some hardware-specific features like 5G or advanced camera processing may require manual fixes via tools like Treble Info.
Unlocking the Bootloader: Officially, this is not possible. However, some users have reported success using expensive third-party tools or "paid services" often found on forums like XDA Developers. Popular "Workaround" Features
Instead of a full ROM, many users opt for these "ROM-like" enhancements to regain Google services or customize the OS:
Huawei P40 Pro Complete Guide To Install Native Google / GMS
Before discussing any ROM, the single most important fact must be understood:
Huawei locks the bootloader on all its modern devices and no longer provides official unlock codes.
A locked bootloader is a security feature that prevents you from flashing any unofficial software. Without unlocking it, you cannot install a custom ROM. For the P40 Pro, this means:
Conclusion: Before you even think about a custom ROM, you must verify that your current EMUI version is unlockable (typically EMUI 10.1 or early 11 builds). If you’ve taken recent over-the-air updates, you are likely out of luck.
1. LineageOS (The Most Viable)
This is the most popular choice for P40 Pro owners who want to ditch Huawei software entirely. Builds are maintained by independent developers (e.g., Surdu_Petru on XDA). It provides a clean, near-stock Android experience.
2. Evolution X (For Customizers) This ROM tries to replicate the Google Pixel experience. It includes Pixel Launcher, live wallpapers, Now Playing, and extensive theming via Monet. However, it is less stable than LineageOS.
3. The “GMS Patch” Route (Not a True Custom ROM) This is the most common method for P40 Pro users who don't want to unlock the bootloader. It uses tools like Googlefier or LZPlay to install a virtual environment or device ID spoofing. This is not a custom ROM—it runs on top of EMUI. It works for basic apps but breaks with security updates and is unreliable for banking apps or Google Pay.
The keyword "Custom Rom For Huawei P40 Pro" is a dream for many—a way to have Huawei's hardware with Google's software. In reality, it is a technical nightmare with a 90% failure rate. You will lose the camera, might brick the modem, and spend weeks fixing random bugs.
If you successfully install a GSI, treat it as a secondary device for tinkering, not your daily driver. For the other 99% of users, appreciate the P40 Pro for what it is: the last great Huawei flagship with a unique, locked operating system.
Stay safe, stay stock, and buy a Pixel if you need custom ROMs.

I have included a disclaimer at the start, which is crucial for Huawei devices due to the difficulty of unlocking bootloaders.
Yes and no. Unlike a OnePlus or Xiaomi device, you won’t find an official LineageOS or Pixel Experience build for the P40 Pro. The development community for Kirin-based Huawei devices is tiny because Huawei doesn’t release kernel sources properly.
However, the community has developed "ported" ROMs. These are not built from source code; instead, they are heavily modified stock Huawei firmware with Google services grafted in.
No. Absolutely not.
Unless you are a developer, a security researcher, or have a spare P40 Pro to burn, Do not install a custom ROM on your Huawei P40 Pro.
The phone was designed as a walled garden. Removing Huawei’s software breaks the hardware. You will end up with a device that has a broken fingerprint sensor, a crippled camera, and unstable mobile data.
The Smarter Alternative: Instead of a custom ROM, use MicroG or Gbox to run Google apps inside Huawei's native OS. Or, sell the P40 Pro and buy a Xiaomi 13 Pro or Pixel 7 Pro if you want custom ROMs.
