These are the steps to update the Galaxy Nexus I9250 to the SlimLP custom ROM based on the latest Android 5.1.1 Lollipop. As most of you will already know, there are no more official software updates coming the Galaxy Nexus’s way. There are still some third-party developers looking after this device, though, since it is one of the most popular devices out there. The following guide will let you taste the latest Lollipop unofficially with a new ROM. The ROM is a stable one and should be fine for your daily smartphone.

  1. Download both the files from the files section above to the desktop of the computer.
