CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5 (Lollipop), which is designed to increase performance and reliability over stock Android for your device.

* you point the finger at me for messing up your device, I 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.

Installation:

For switching to F2FS, see POST#3

1. Download ROM zip and GApps zip.

2. Extract boot.img from the zip and flash it via fastboot

3. Boot into recovery.

4. Wipe System, Data, Cache, Dalvik Cache.

5. Flash ROM zip. (it may take some time)

6. Reboot to system and let it settle.

7. Reboot and flash GApps zip. You must flash gapps after every upgrade to CM12 since /system is formatted, wiping your previous add-ons.

ROM:
