[Galaxy Note 3 General] andr01dfr3ak:
LineageOS is a free, community built, aftermarket firmware distribution of Android 8.1 (Oreo), which is designed to increase performance and reliability over stock Android for your device.

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. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

WARNING:

This is not a stable version of LineageOS. If you run into problems, give us a logcat as you report your problem or GTFO.

If your problem cannot be reproduced without using Magisk modules or Xposed, don't report it! The same goes with custom kernels.

Prerequisites:

The latest version of TWRP. This is an absolute requirement.

Your Samsung Galaxy Note 3.

The latest modem and your bootloader unlocked. Link on how to get that done is found below.

How to flash this ROM:

From other custom ROMs (RR-O, LineageOS 14.1, etc):

Download the zip file for your variant of the device. Use the table below to figure out which variant to use.

Make sure this zip file is saved to your device (just to get things done quickly).

If you want Google Play functionality, download OpenGApps (link below). (optional)

Reboot into TWRP (Volume Up + Home + Power or Advanced Restart).

Make a backup (optional).

Wipe System, Data, Cache, and Dalvik Cache partitions with Advanced Wipe. (required if upgrading from LOS 14.1 or RR-N)

Flash the ROM you just downloaded.

Flash OpenGApps for Android 8.1 if you want Google services (optional).

If you want root, flash Magisk.

Reboot and proceed normally with installation.

From LineageOS 15.1 (if you're updating):

Download the zip file for your variant of the device.

Reboot into TWRP.

Flash the zip file as normal. No wipes needed.

Reboot. You have updated your device.

Variants:

It is important that you get the right variant based on your model code! Otherwise, you might not be able to make phone calls, and run into other bugs!

hlte: SM-N9005 (unlocked, GSM) and SM-N900P (Sprint)

hltetmo: SM-N900T (T-Mobile), SM-N900W8 (Canada), SM-900R4 (USA Cellular), SM-N900V (Verizon)

hltechn: SM-N9008V and SM-N9006 (both are China)

hltekor: SM-N900S (SK Telecom), SM-N900L (LG Uplus), SM-N900K (KT Corp)

The Exynos variant (ha3g) is bound to gain support soon.

The SM-N900A (AT&T) might never get support due to its locked bootloader. That is unlikely to change.
