CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.0.2 (Lollipop), which is designed to increase performance and reliability over stock Android for your device.​

 * Your warranty is now void.
 * We are not responsible for bricked devices, dead SD cards,
 * thermonuclear war, or you getting fired because the alarm app failed. Please
 * do some research if you have any concerns about features included in this ROM
 * before flashing it! YOU are choosing to make these modifications, and if
 * you point the finger at us for messing up your device, we will laugh at you.
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. You will need to provide your own Google Applications package (gapps). 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 our Gerrit Code Review. Your changelog is whatever was merged into gerrit.

We have de-unified the Galaxy S4 line. Too many issues with having them all in one and a maintainer's nightmare. Look for jfltexx builds now as opposed to the jflte builds you previously used.

Tried clean flash of jfltexx cm12 to 9505G. Using twrp for jgedlte, ext4. Getting "E: error executing binary updater in zip" then "E: unable to mount /system." CM11 was able to flash jfltexx to jgedlte, guess this isn't true for CM12?

Ciao, I've flashed the cm12 nightly but twrp says that my device is jfltecan, I was on cm12 optimized, have I to modify build.prop and then re flash?
Edit: solved changing recovery.
