[Samsung Galaxy S Duos] billysam:
CyanogenMod (CM 10.1)

Android 4.2.x & CyanogenMod (CM10.2) Android 4.3.x ​

Note: This is build from source for the device s7560 jellybean Rom, this is the same rom that also works on s7562 device, which is, same as our device in everything except it's a single sim phone.

I tested them on my device and it works the smoothest and fastest, I have ever gone on S duos. OC kernel works good, apart from that this is not recommended for daily users.

CyanogenMod is a free, community built, aftermarket firmware distribution of Android 4.x (Jelly bean), which is designed to increase performance and reliability over stock Android for your device.

About CM

CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

Miscellaneous Information:

The development of jellybean stopped years ago and it is unsupported until today. it has some major bugs regarding network, bluetooth, offline charging, FM radio. but those of us who use this phone as nothing more than a toy or use wifi for browsing internet, can try these for themselves and see how good this device can perform. Asking devs to help us here is too much and really these bugs aren't easy to solve, I know Because I tried and failed myself. well codename13 has his work saved on github for cm10.2 and anyone who wants to try to be a successful dev can check it
