CyanogenMOD
CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.1 (Lollipop), which is designed to increase performance and reliability over stock Android for your device.

Code:
* 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. 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.


Install instructions:
  • Reboot into recovery (latest official TWRP recommended).
  • Wipe Data, System and Cache if it's a fresh install.
  • No wipes required if you're updating from a previous version of CM 12.1 (Wipe Cache and Dalvik Cache recommended).
  • Flash ROM + Gapps.
  • Reboot.

Please, read post 2 before reporting bugs or asking questions.

KitKat bootloader/modem is required, you can find it on post 3.

A) Open dialer, dial *#*#4636#*#* , open first option "Phone Information", there you can set your preferred network mode.

KitKat bootloader/modem files

This zip contains the bootloader and modem files from latest stable international release (MIUI7 V7.0.5.0 KitKat). I made it so users don't have to download and install the official zip, which also includes the rom. It's a flashable zip, so just install it from recovery and reboot (no wipes required).

Firmware 7.0.5.0: https://www.androidfilehost.com/?fid=24052804347850305
