[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mmontuori:
Introducing MROM-d2att. Custom ROM for the Samsung Galaxy S III SGH-I747

Free Yourself and Feel the Difference​

This is my attempt to build a stable, complete, and fully functional custom ROM for the Samsung Galaxy S III completely built from source code; MROM-d2att is built on top of Cyanogen ROM latest 4.2.2 (cm-10.1) source code, branched kernel, and my own blend of proprietary drivers. I recompiled all components to guarantee maximum efficiency and performance. Along the way, I realized that I needed things to work different for the d2att, so I also made some changes. If you like my work, consider a donation to my cause.

BUILT FROM SOURCE PROOF https://github.com/MROM. Every developer should provide proof that he is building from source.

MROM-d2att is entirely build from source. You will see the difference when you run it. Just to list a few features:

Entire ROM and Kernel are compiled and optimized with Linaro toolchain 4.7

Superior Performance. (User benchmarks have reported excellent performance)

Latest Kernel 3.4.x (http://www.kernel.org)

Fast Boot time

Multi-User Enabled

Excellent battery life

Contains all the most common tweaks

QuickPic gallery application

While I tried to maintain the main core small, size is not the main focus.

Few user comments:

Oleschuldad: this has been much more reliable then the other 4.2.2 roms I've flashed, no random reboots, no lags, or a2dp problems....

CQCmaster: The best Rom in terms of performance and battery life and stability.

JoeSchmoe22: I am happy to report that the BATTERY LIFE IS AMAZING!!! I am a heavy user and now my phone lasts all day! Also, the Rom is totally stable!
