Just a month after the launch of the Pixel 6 and 6 Pro, we now have the very first custom ROM for the duo in the guise of ProtonAOSP.

While most Pixel 6 owners will stick firmly with the stable builds that come pre-installed upon their devices, some out there will be itching to slap a custom ROM on their brand-new device. While we have already started to see a few Android 12-based ROMs over the past few months, it has taken a little over a month for the first ROM to be made available for the Made by Google duo.

The brand-new Tensor chip could have posed a problem, but it hasn’t held up the development of ProtonAOSP for the Pixel 6 and 6 Pro. For those unaware, ProtonAOSP is a custom ROM that takes a minimal approach while simultaneously enhancing performance and adding some added privacy controls.

Developer Danny Lin (@kdragon) confirmed that the Pixel 6 and 6 Pro are now fully supported with builds available to early access supporters right now — with an image of both devices running his custom ROM. ProtonAOSP has been in testing since November 15 with a number of tweaks and tuning that might pique the interest of custom ROM fans. This support comes with ProtonAOSP v12.1.0 and includes support for all of the main Pixel 6 hardware including the in-display fingerprint scanner, Wi-Fi, and cellular connectivity functions plus almost all core features present.
