[Nexus 7 Original Development] synergye:
​

This is a team effort by all Team codefireX members listed below, as well as many other developers and users in the android community. The kernel is CM10.1 kernel built from source using cfX-Toolchain, however as of writing this thread, most all custom kernels in this forum should work.

The codefireX team:

synergy(e) - lead dev

Mustaavalkosta - lead dev

michyprima - dev

Pnoire - bug tester and french translator

Rdlgrmpf - contributor

BananaGranola - contributor

Unlike with some other JellyBean roms, I believe that all users should know exactly what is being built in/for the ROM. That is why all the repos I use and maintain are available for all to see and contribute to. The codefireX source links are above the download link. Please do not ask me to include any prebuilt or proprietary applications in this ROM; I will refuse, or ignore you entirely. Using non-vendor proprietary or closed source applications/ROMs is and always will be a security concern I would rather not expose users to.

Click HERE for a full cfX settings feature flowchart by BananaGranola (thank you!)

NOT a re-named CM build

Based on AOSP master (not release) with regular AOSP master merges

Open Source as all AOSP ROMs deserve to be

Easily switch between a custom and "vanilla" experience in the settings app "on/off switch"

LOTS of customization options including quick settings

Built with a custom linaro based gcc4.7.3 toolchain, strict aliasing, -O3 completely (including thumb_cflags), graphite optimizations, and other optimizations such as OOM/LMK changes. JUST TRY TO FIND A FASTER SOURCE BUILT JELLYBEAN ROM!

Lots more but I'm boring myself already
