40CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.1.x (Lollipop), which is designed to increase performance and reliability over stock Android for your device.
Code:/* * Your warranty is now void. * * I am not responsible for bricked devices, dead SD cards, dead cats, * thermonuclear war, or you getting fired because the alarm app failed. * YOU are choosing to make these modifications, and if * you point the finger at me for messing up your device, I will break it! [emoji14] * Act accordingly */
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.
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. You can also view the Changelog for a full list of changes & features.

Xiaomi still refuse to release Redmi 2 kernel source, they continue violate the GPL accompanied by ex. Google Hugo Barra.
I believe more than one hardware revision available out there, luckily this port working smoothly on my own Redmi 2 device. Some facts:
Compass chip Yamaha YAS537 known not supported, Asahi Kasei Microdevices AKM09911 working flawlessly- I'm afraid Wingtech use a different battery charger management chip on selected model, SMB13x chip supported
- My device model HM2014817 1GB RAM, board revision S88047E1, R61308 LCD driver with AUO3.5 LCD panel, AKM09911 compass chip

Camera server sub module (imglib) crash, kernel space stopped because of user space problem

Solution:
Restore some Smartfren Andromax Q (known built for Lollipop) https://github.com/kumajaya/proprie...mmit/d20417a6a35c9ac52cd8e359b0420aab51313c47
Conclusion:
For KitKat camera blobs, a compatible kernel driver needed because user space system call slightly different to the current kernel. How I did it fairly easy, you can trace my kernel commits on github. The rest, you can trace my proprietary vendor blobs commits.9Mainly from official Cyanogen device: bacon (because I have OnePlus One), rendang, lettuce, tomato, crackling, kipper, r7plus for YAS537 reference driver, etc. Oh God, it's hard because of Xiaomi stupidity.
