[Android General] Alberto96:
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. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.

First Release

Previous Releases:

None yet.

Installation

2-button-combo = "Volume Up/+" + "Power/Lock"

- First time flashing LineageOS 13.0 to your device?

Install TWRP/GearRecovery. Available here: Development & Support Thread

Reboot to Recovery (use the 2-button combo to get into the Boot Menu, then choose "Recovery Mode").

ALERT: if your device doesn't boot to TWRP, you will need to repeat the TWRP flashing procedure. Remember to not boot the device after flashing TWRP otherwise the Stock ROM will overwrite any customization you did before.

As soon as your device reboot into TWRP for the first time, you will see a message. Accept it.

Wipe Everything by following this order: "Wipe" -> "Advanced Wipe" -> Check Everything (System, Cache, Data, Internal Storage) -> "Swipe to Wipe".

Now go back to the main menu by pressing two/three times the Back Button.

Reboot your device into recovery mode again. ("Reboot" -> "Recovery")

You will see the same first-boot message, again accept it.

Your device is now super-clean. Go to "Mount", "Enable MTP" (if it says "Disable MTP" you are good to go), and connect the device to your PC.

Copy the latest available ROM on your Internal Storage, together with OpenGapps if you need them.

Press "Disable MTP" and go back to the main menu.

In order to install the ROM: "Install" -> Choose the .zip ROM Archive -> "Swipe to confirm Flash"

If you need to install OpenGapps, follow the same install procedure (the previous one) with the .zip OpenGapps archive.

Done! You can now reboot the phone (always back, then "Reboot", "System") to enjoy the ROM :)

- Upgrading from another build of LineageOS 13.0?

Reboot into Recovery using 2-button-combo

Do a Backup! (if you need to)

Install the ROM: "Install" -> Choose the .zip ROM Archive -> "Swipe to confirm Flash"

Press "Wipe Cache/Dalvik" and Swipe again.

Done! You can now reboot the phone (always back, then "Reboot", "System") to enjoy the updated ROM :)

Known Issues and/or not working features

!!! BUG REPORTS ABOUT ALREADY KNOWN ISSUES WILL BE IGNORED !!!

Camera HDR doesn't work. (requires too much proprietary code from Mediatek)

Camera Auto-Exposure is less efficient than how is on Stock ROM (same reason as above)

Voice over LTE, aka VoLTE or HD Voice, isn't supported. (and probably won't be supported ever, same reason as above)

If present, other bugs will be added (and maybe fixed) based on users feedback.
