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.

These unofficial builds are based on the CM t30 Kernel available at https://github.com/CyanogenMod/android_kernel_acer_t30

All my specific device tree can be integrated in the CyanogenMod project.

Requirement

An unlocked Bootloader - JB Version

CWM recovery or TWRP recovery

version 6.0.5.0+ with LVM Support (Look at the CWM thread) or TWRP with LVM Support (called bigsystem by Elibl)

Installation

Do a Nandroid Backup!

Wipe data/factory reset if coming from another ROM or version of CM. If you are already on CM12 or a previous build of CM12.1, just make Wipe Cache & Wipe Dalvick-Cache for a proper upgrade.

Install the ROM using Recovery

Install the adapated Google Apps (Latest Paranoid Gapps for 5.1)

Note: The partition layout of CM12 is identical to that of CM11 with LVM and thus you may use CWM with LVM to backup/restore.

Bugs & FAQ

Known Issues:

RIL not compatible with A511 :(

Flashing L might take a while in recovery (please be patient)

First boot might take a while too !

Setting brightness to minimum while on auto brightness may cause the screen to go completely dark with no way to set it back except for guessing where the brightness setting is or using adb to force set a higher brightness. (should be fixed)

If you have a black screen at first boot or after bad settings manipulation, use this commande in adb :

adb shell "echo 255 > /sys/devices/platform/pwm-backlight/backlight/pwm-backlight/brightness"

If it doesn't work, push power to enable your screen and try the command again.

If the bug comes with auto-brightness enabled, you can put your sensor on a light to force it to level up the brightness.

SELinux not in enforcing mode

GPU HWComposer & HDMI, please check this post
