Another Jelly Bean Android 4.1 custom ROM is out for the Asus Transformer Prime, this time by Team EOS, a development team with ROMs for many other devices. The ROM is built from sources and gets you Jelly Bean on your Transformer Prime, with all its features such as a 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.
