WARNING! Unofficial ROMs for the Samsung Galaxy S4 Mini (GT-I9190 and GT-I9195 variants only!)

CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.0 (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.
