Thanks to both XDA forum members, Sahil Lombar that brings Jelly Bean AOSP to the Sensation and Sportsstar89 using the form of CyanogenMod has made to bring AOSP to Amaze 4G.
However the both ROMs are still in alpha stage, therefore expect imperfect from them. Not everything works, but there are numbers of other features work.
Below is a list of features that work and don't work on the Sensation.
- Core System
- Hardware Acceleration
- USB Storage
- Vibration Motor
- GPS (Kinda)
- Google Now
- Light Sensors
- Button and Notification lights
- and many other things
And as for Amaze 4G:
- Wi-Fi (Got borked again)
For more details, you can either visit the HTC Sensation JB thread or the HTC Amaze 4G JB thread.
