LineageOS is a free, community built, aftermarket firmware distribution of Android 7.1 (Nougat), which is designed to increase performance and reliability over stock Android for your device.

* Your (probably expired) warranty is now void.
*
* I am 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 me for messing up your device, I will laugh at you.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit Gerrit Code Review.

TWRP 2.8+ is recommended.
