One of the first custom ROMs based on Android 4.1 Jelly Bean for the Verizon Galaxy Nexus has been released by the famous development team called Team EOS, who also released the same ROM for the Sprint Galaxy Nexus. It is a ROM built from the official Jelly Bean sources, with all the Jelly Bean features and improvements included.
Jelly Bean brings many improvements over Ice Cream Sandwich, including a much smoother interface, improved and more useful notifications area, better stock keyboard, advanced search functionality with the new voice recognition based Google Now, and quite a few small but nonetheless important improvements. Check the full list of what’s new in Android 4.1 → here.
NOTE: This is an early build of the ROM, so there may be a few bugs and issues in the ROM, though most things should work properly. Also, the ROM is in the nightlies stage. Nightlies are ROM builds that are built automatically now and then (every night by actual definition), incorporating all the latest changes made to the ROM’s code from the last nightly. Even though care is taken by the developers to make sure the code submitted for each nightly is stable, some things can go wrong with a new nightly as the builds are automatic and cannot be tested before release.
Let’s take a look at how you can install Android 4.1 on your Verizon Galaxy Nexus with EOS ROM.
This ROM and the guide below are compatible only and only with the Verizon Galaxy Nexus. It’s not compatible with any other device. Check your device model in Settings » About phone.
