Partial Bootloader unlock + custom ROM

Difficulty

Moderate

Brick risk

Medium

Legal risk

Low

Not stock root. Needs an unlocked bootloader and a custom ROM.

Verizon and some carrier-locked Pixels cannot unlock the bootloader; factory/unlocked models can.

How-to

How to

LineageOS official build: unlock bootloader (fastboot/OEM), flash LineageOS recovery + ROM. Mainline Linux alternative via postmarketOS (community).

Follow the specialist sources linked on this page. If this path is a jailbreak, unlock, or flash, the specialist wiki is the how-to — we do not copy those steps here.

Notes

Some TWRP and postmarketOS builds for this device are based on LineageOS device trees.

pmOS uses independent kernel (mainline or sdm670-mainline).

Install with fastboot.
