This ROM is compiled from NIGHTLY s

This ROM is compiled from NIGHTLY source instead of monthly M - builds source.

For monthly M builds, check THIS ORIGINAL THREAD by the respected developer, @pawitp.
All credits for this ROM, as well as all other AOSP based ROMs for Galaxy Grand goes to him.


pawitp has repeatedly mentioned that he will only provide pure CM11 ROM builds. I needed dual-SIM in AOSP but with a few feature additions and optimizations. I tried Carbon and PA with pawitp's patches to enable dual SIM in them, but I was unsuccessful. So I compiled CM11 with few things that I wanted and sharing it.

This ROM will stay very close to pure CM11, with very few additions and changes. I'll upload the zip whenever I compile for myself. I'll only provide full ROM zip files and no delta zips.



EXTRA ADDITIONS

Compiled from bleeding edge NIGHTLY source of CM11
Compiled using Linaro 4.8.3 toolchain
O3 optimization flag
Link Time Optimization flags - read more about it HERE
APP2SD support - ability to move apps to external SD card
Multi-user support



DUAL-SIM

Dual-SIM works
Instructions on how to activate and deactivate dual SIM can be found in FAQ in the original post by @pawitp - HERE
You can also use my app, MultiSIM Toggle, to activate or deactivate dual-SIM functionality. Read more HERE.



IMPORTANT

If you are using my build of CM11, do not report bugs or issues in pawitp's thread. Post them here.
