Jelly Bean based ROMs are surely coming at a really fast pace these days. The Acer Iconia Tab A500 has received a preview build of CM10 based on Android 4.1 Jelly Bean by XDA Senior Member waydownsouth, with 90% of the hardware already working according to the developer despite CM10′s early development stage, including audio/sound which wasn’t working in the previous Jelly Bean ROM released for the A500.
NOTE: The ROM is a work in progress and hence may have bugs and issues present in it, along with a few things that may not work properly. Also, do not expect to see many customization options of CyanogenMod to be present in the ROM right now as CM10 is in its early stages.
Here’s a list of things working/not working currently, quoted from the development page:
- GPS (Hax)
- 2d/3d acceleration
- HDMI video
- HDMI audio?
- H/W rotation lock
- Issue: EGL memory leak (most apparent in chrome browser)
- will add more as we discover them
