Asus Transformer Gets a Jelly Bean Android 4.1 ROM too, Here’s an Installation Guide

The Transformer that started it all – the original Transformer TF101 – has received a port of an Android 4.1 Jelly Bean thanks to XDA Senior Member rayman33. Jelly Bean features a smoother interface, faster performance, advanced voice recognition and search functionality, better and smarter keyboard, improved and actionable notifications area, and a lot more which you can read about here, which you can now experience thanks to this ROM.

NOTE: The ROM is a work in progress and quite an early release, so bugs and issues are to be expected and some things may not work properly or at all, so consider this purely a preview of Jelly Bean. The ROM might not be suitable for daily use.

Here’s the list of currently working/not working things, quoted from the official development page (where you can get the latest list of issues):

What works :

  • Android 4.1.1 system
  • UI elements (EasterEgg when tapping on the version number does work, too)
  • Launcher is buttery smooth !
  • Live wallpapers
  • Bluetooth
  • adb push/pull/…commands
  • Overclock up to 1.6 GHZ stable (included Harmony Kernel modded for JellyBean)
  • Gallery App
  • Keyboard Dock (once docked, it will let you choose your language)
  • Lockscreen
  • Rotation (no blackscreen!)

What doesn’t :

  • WiFi (works, but fails at obtaining IP-adress)
  • Camera
  • Sound (using volume buttons will cause your device to freeze)
  • Music App (due to sound issues, will force-close)
  • Maybe more …?
