The whole process will involve changing a file in the /system/app section of your device using a root explore app, adding in a new file and mounting the system. Then you need to reboot and install a voice app from the Play Store. If you are already lost then you might just want to sit this one out.
-searching through the text-box works
-location services work
-info cards work
-notifications work without modifying build.prop
-Voice now works through Jonny_G’s app
-Can’t exit the app using the back button on the Google Now ‘Cards’ screen
-Full Jelly Bean voice search
Devices this will NOT work on:
-Devices that are running anything before Android 4.0 Ice Cream Sandwich
-Devices not running an AOSP ROM (in most cases, try anyway and report back)
Still interested in giving it a test? Ya, we thought you might. We know David already has it up and running on his HTC One S sporting an AOSP build and he says it is working great and is really fast. He already set a calendar event. If you want to give it a go, head over to SilentStormer’s XDA thread for full instructions, required files and to join the discussion.
