LineageOS is a free, community built, aftermarket firmware distribution of Android 6.0 (Marshmallow), which is designed to increase performance and reliability over stock Android for your device..
#include /* Your 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. 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.
Device-specific source code for the Samsung Galaxy Grand Duos are available from https://github.com/Iguma1/cm13_device_samsung_i9082 and kernel tree https://github.com/ghsr/android_kernel_samsung_i9082/tree/cm-13.0-setns
RIL (Calls, SMS, Mobile Data)
Sensors (Accelerometer, Compass, Light, Proximity, etc.)
Video (playback & recording)
Audio (playback & recording)
Everything else not listed under "known issues"
Sometimes wake up causes music stutter
Does not work on 4.1 stock ROM's bootloader, please upgrade to stock 4.2 before flashing
Additionally, Dual SIM has the following limitations (once they work):
Both SIMs are always enabled (no way to disable one SIM)
"Receive incoming call while data is enabled" is always enabled
Make a backup!
If you were on CM 10.1 or a stock ROM prior to 4.2, upgrade to stock 4.2 first.
Install ClockworkMod recovery with SELinux support. Older CWM will result in a "status 7" error.
Reboot into recovery
If you are using a recovery which mounts /system on boot, unmount it before installing
Wipe data if coming from stock or other ROMs (You may get a "status 7" error if you fail to wipe.)
Install the ROM
Optionally install the Google Apps Addon (In Marshmallow, you MUST flash gapps before booting into the system for the first time or else the proper permissions will not be granted resulting in Setup Wizard crash. If you experience the crash, you will need to do a factory reset.)
To upgrade to a newer build, simply flash the zip. There's no need for data wipe or flashing Google Apps again. (However, if you are experiencing strange issues, you may want to try a wipe.)
