Google Pixel 2 XL · experimental candidate 6

Experimental · Published 2026-09-30

Download Windows, macOS and Linux installation bundle · 823.5 MiB

Experimental browser installer · or use the native scripts below.

No Python required. Install current Android platform-tools, back up your phone, and unlock its bootloader using the device guide. Verify the bundle checksum and build provenance, then extract the ZIP.

gh attestation verify google-taimen-native-v2.zip -R porthole-dev/pmaports

Linux or macOS, from the extracted folder:

bash install.sh

Windows PowerShell, from the extracted folder:

powershell -NoProfile -ExecutionPolicy Bypass -File .\install.ps1

The Windows command permits the verified script for this process only. Both installers check image hashes, the model and unlocked bootloader, then ask you to type the device name before erasing data. They never unlock the bootloader automatically. To verify and preview without contacting a phone, use bash install.sh --dry-run or powershell -NoProfile -ExecutionPolicy Bypass -File .\install.ps1 -DryRun.

Download Python installation bundle · 823.5 MiB

One download includes the matching rootfs, boot, DTBO, checksums, source revisions and installer. Separate files remain below.

Verify bundle checksums and provenance before running:

gh attestation verify google-taimen-install.zip -R porthole-dev/pmaports
python3 google-taimen-install.zip

Requires Python 3.8+, current Android platform-tools, an unlocked bootloader and a backup. The installer checks the model and asks before replacing the OS and erasing user data. Add --dry-run to verify and preview without contacting a phone.

Manual installation and recovery

Installation

Target: Google Pixel 2 XL (taimen), mainline Linux, Phosh, systemd. Includes the licensed nonfree firmware. This candidate has passed build checks; hardware testing applies only when a report names this exact image checksum.

Verify and unpack

Download every asset into one directory, then run:

sha256sum -c SHA256SUMS
gzip -dk google-taimen.img.gz

The default account is user. The initial password is selected by the maintainer through the release environment. Change it after installation.

Full installation

Flashing replaces the installed operating system and user data. Back up first. The bootloader must be unlocked. Use a current Android platform-tools fastboot. These instructions target the port’s tested slot b. Never activate slot a.

From the bootloader, verify that fastboot identifies your Pixel 2 XL before performing these writes:

fastboot devices
fastboot flash userdata google-taimen.img
fastboot flash boot_b boot.img
fastboot flash dtbo_b dtbo.img
fastboot set_active b
fastboot reboot

The DTBO write is required: the stock overlay does not match the mainline kernel. Keep boot.img, dtbo.img, and the rootfs from the same release together.
