Asus Zenfone 9 Lineage Os [updated] -

As of April 2026, LineageOS does not officially support the ASUS Zenfone 9 [21, 22]. While the Zenfone 9 is a highly-regarded compact flagship, the custom ROM scene for it is currently limited due to ASUS's decisions regarding bootloader unlocking. Current Status & Obstacles

Official Support: The Zenfone 9 is absent from the official LineageOS device list [21].

Bootloader Issues: ASUS reportedly disabled its official bootloader unlock tool for newer devices around August 2023 [13]. Without an unlocked bootloader, you cannot flash LineageOS or any other custom ROM [13, 16].

Development Community: Due to the small user base and restricted unlocking, the custom ROM community for this specific model is largely inactive [11, 13]. Alternatives for Zenfone 9 Users

If you are looking for a cleaner software experience or extended support, consider these limited options:

Rooting (if previously unlocked): If you were lucky enough to unlock your bootloader before ASUS shut down the tool, you can still root your device using the Magisk Manager to gain administrative control over the stock OS [7, 11].

Custom Kernels: There have been some developments in custom kernels that work with the stock ASUS OS to improve performance or battery management, though these do not change the underlying operating system [12].

GSI (Generic System Images): Some advanced users attempt to flash GSIs (like AOSP) on devices with unlocked bootloaders, but these often come with bugs in hardware support (e.g., camera or fingerprint sensor issues) [5.2]. Why LineageOS is Often Desired

For users on supported devices, LineageOS remains a popular choice because it is:

Bloatware-Free: It provides a lean Android experience without pre-installed manufacturer apps [24].

Privacy-Focused: It allows users to run Android without any Google services if desired [24, 25].

Longevity: It often provides the latest Android security patches to older devices that manufacturers have stopped supporting [4, 27].

The Asus Zenfone 9

remains a rare gem for compact phone enthusiasts, but the dream of running LineageOS on it is currently effectively impossible for most users. The Bootloader Roadblock

As of late 2023, Asus removed the official bootloader unlock tool and disabled the associated servers.

No Unlocking: Without the ability to unlock the bootloader, you cannot flash custom recoveries or operating systems like LineageOS.

Stagnant Community: Because most units remain locked, the developer scene is largely dead. Any existing ROMs (like older builds of OmniROM) haven't seen updates in over a year.

Stock Experience: The silver lining is that the default ZenUI is already very close to a stock Android experience and contains almost no bloatware. Hardware Highlights (The "Mini" Flagship) If you decide to stick with the stock software, the is still a high-performance machine.

Compact Power: A 5.9-inch 120Hz AMOLED display powered by the Snapdragon 8+ Gen 1.

Gimbal Camera: Its unique 6-axis hybrid gimbal stabilization provides some of the smoothest handheld video available on a phone.

Exceptional Battery: Despite its small size, users frequently report nearly two days of battery life on a single charge.

Forgotten Features: It includes both an IP68 rating for water resistance and a 3.5mm headphone jack.

The ASUS Zenfone 9 (codename: sake) has excellent support in the LineageOS ecosystem. Because the device uses a mostly stock Qualcomm chipset and ASUS was relatively developer-friendly (providing kernel sources), the port is considered very stable. asus zenfone 9 lineage os

Title: [ZS_9] One week with Lineage OS on the Zenfone 9 – my honest take

Body: I finally took the plunge and unlocked the bootloader on my Zenfone 9. Here's my experience after 7 days on the latest Lineage OS 22 (Android 15):

✅ The good:

Zero lag. Feels faster than stock.
No ASUS duplicate apps (no more two clock/calculator apps).
Battery: 6-7h SOT easily. Deep sleep works perfectly.
Updates via OTA – seamless.

⚠️ The trade-offs:

Lost the stock camera's gimbal stabilizer algorithm – using GCam mod as a workaround.
No VoLTE on some carriers (check your region first).
Fingerprint reader is slightly slower than stock.

Overall? Worth it for the privacy and performance. If you love small phones and hate bloat – do it.

Here’s a solid, self-contained piece of information regarding Lineage OS on the ASUS Zenfone 9.

Device codename: zenfone9 (or sometimes AI2202)

Official Lineage OS status: Not official (as of April 2026). The Zenfone 9 is not listed on the official LineageOS devices page. However, highly functional unofficial builds exist.

Key Unofficial Build (most referenced):

Maintainer: timoxd7 (known for quality ASUS Zenfone builds)
Android version: Usually Lineage 21 (Android 14) or 22 (Android 15)
Where to find: XDA Developers Forums (Zenfone 9 section) or Telegram groups dedicated to Zenfone 9 development.

What works (typical for this device):

Almost everything: WiFi, Bluetooth, mobile data, 5G, VoLTE (with correct firmware), GPS, audio, fingerprint sensor, camera (with GCam mod recommended)
120Hz refresh rate
Zenfone’s unique physical gestures (double tap/ swipe on fingerprint sensor)

What may not work / limitations:

Asus’s own camera app features – You’ll lose the full 6-axis hybrid gimbal stabilizer’s proprietary software tuning. Use GCam (Google Camera) ports to regain excellent stabilization.
Widevine L1 – May drop to L3 (no HD Netflix/Prime Video) on some builds; check the specific build notes.
Seamless updates – Not applicable (Zenfone 9 uses A-only partition layout, so OTA updates are more disruptive than on A/B devices).

Prerequisites to flash:

Unlock bootloader using ASUS’s official unlock tool (available from ASUS support site; erases all data, breaks warranty in some regions).
Use a USB-C data cable (not just charging cable).
Install ASUS USB drivers (Windows) or have fastboot working (Linux/macOS).

Recommended recovery: Lineage Recovery (provided alongside unofficial build) or TWRP (if available for same Android version).

Common issue & fix:
If touch screen behaves strangely after flashing, update to the latest stock ASUS firmware (Android 14) before installing Lineage – the kernel and touch firmware must match.

Bottom line:
Yes, you can run Lineage OS on Zenfone 9, but only via unofficial builds. It’s stable enough for daily use if you don’t rely on the gimbal camera’s proprietary features. Expect updates to arrive weeks or months after new ASUS stock firmware drops.

. While the older Zenfone 8 had official support, the Zenfone 9 has been largely bypassed by the official maintainers. Bootloader Obstacles

: ASUS officially disabled its bootloader unlock tool for the Zenfone 9 around August 2023. This tool is a prerequisite for installing custom ROMs like LineageOS. While an unofficial method briefly worked, ASUS released firmware updates (e.g., version 33.0804.2060.189) specifically to block these workarounds and prevent firmware downgrades. Community ROMs

: The custom ROM scene for this specific model is considered "dead" by many in the community. Only a few older builds of alternative ROMs like OmniROM or AOSPA exist, but they have not been updated recently. Why Support is Lacking Small Community

: The Zenfone 9 has a relatively small user base compared to mainstream flagships, resulting in fewer developers willing to maintain complex builds. Manufacturer Resistance

: Users have reported that ASUS has actively sabotaged community efforts by disabling the web endpoints (dm.asus.com) required for unofficial unlocking tools. Alternatives for Users

Potential Pitfalls & How to Avoid Them

2. Enabling Dirac (Asus Audio)

If you miss the bass boost, you can flash a Magisk module called Dirac_Sound_For_Zen9. This re-injects the Asus AudioWizard libraries. It's not official, but it works well.

1. Current Status & Availability

Official Build: The Zenfone 9 is officially supported by LineageOS 21 (which is based on Android 14).
Maintainer: The device is maintained by a specific developer (often recognized contributors in the LineageOS community like npjohnson or others active in the sake device tree).
Variants: The builds generally support all regional variants of the Zenfone 9.

The Camera Saga

You will not get Asus Camera automatically. You must sideload two APKs:

Aperture (Lineage's default camera): Good for quick snaps. Okay quality.
BSG GCam (MGC_9.2.xxx): This is mandatory. With a proper XML config file (search XDA Forums for "ZenFone 9 GCam config"), the photos are 95% as good as stock. Portrait mode, Night Sight, and astrophotography work brilliantly. The main camera sensor is excellent hardware; GCam unlocks it.
Loss: Ultrawide video stabilization is worse. No 8K recording (unusable on stock anyway).
