About Project:


This is my new project dedicated to all Nexus 5 users!

It is based on unofficial Unlegacy Android Project 8.1 Beta. I’m not a great programmer, but I know how to achieve my goals.

The goal is to reproduce the Google Pixel 2 system. This ROM also contains some useful tools.

Summary

 

The project was created to prolong the life of the Nexus 5 smartphone. Over 4-year-old flagship from Google is still a very efficient device and allows you to launch the latest games from 2018 years. After upgrading to Android 8.1, Nexus 5 is one of the more interesting phone on the aftermarket, and in the price range from £90 for a 16GB model is unmatched among other devices.

Completing this project and building a site absorbed a lot of my time. I plan to share updates on a regular basis until August 2019, then Google will end support for ARM apps and force the transition to ARM64, which Nexus 5 doesn’t support. In this way, after almost 6 years on the market, the Nexus 5 will go into well-deserved retirement.
