LineageOS is a free, community built, aftermarket firmware distribution of Android 8.1.0 (Oreo), which is designed to increase performance and reliability over stock Android for your device.



Code:
#include <std_disclaimer.h>

 * We are 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 us for messing up your device, we 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. 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.


This thread is for Unofficial LineageOS 15.1 builds for gvwifi (SM-T670). The following will not be supported here:
Custom kernels
Mods
Xposed

I don't support Xposed and any logcat which includes a Xposed module will be ignored. You're kindly invited to not report bugs if you:
Flashed a custom kernel
Installed or did mods from untrusted sources
Modified system files


First time flashing LineageOS 15.1 on your device, or coming from another ROM?
Download the zip(s)
Install a compatible Recovery
Perform a nandroid backup of your current ROM (Optional)
Wipe data/factory reset
Flash LineageOS
Install the Google Apps addon package (Optional)
Reboot

Useful Info
Some tips and tricks:

Due to the light sensor not working I would recommend you use UnderBurn from the google play store in its place it works very well

Due to the device not passing safety net you will need to manually download Netflix I recommend using apkmirror but things like XDA labs works as well. Here is a direct link to the netflix app on apkmirror be sure to download the arm verison.

To control the rotation, I recommend using Rotation Control it allows you to lock the rotation so apps can't change it on their own as well as forcing to true portrait mode.

I doubt the AT&T/Verizon have unlockable bootloaders sadly, the only LTE model that could be supported is SM-T677 international variant

AWESOME!
Give this dev a medal for this awesome ROM! A middling device was turned into total awesome. I also like the galaxy wallpaper, now my Galaxy View has a galaxy view, hahaha.

I'd suggest any number of free rotation control apps. They did NOT work in controlling the orientation of the stock rom, but they work here beautifully for both portrait and landscape.

That's good to know I hadn't tried any yet due to them not working on stock. Do you recommend any in particular? I'll add it to the 3rd post.

I personally use Rotation Control (the one from "CrapeMyrtle", as there's a paid app with the exact same name). I keep the guard option turned on (to prevent apps from changing the orientation themselves) and set it to start on boot with Landscape. It can also force the tablet into portrait mode, (real portrait mode, not pillar-boxed landscape mode) which was impossible in the stock ROM.

New build in OP

Changelog:
Removed Doze Settings
Removed Vibration Settings
Removed Telephony and SMS settings
Made Navigation bar buttons proper size
Disable auto rotation by default (Haven't found a way to disable it fully)
Enabled Tablet optimized grid recents
Made Notification Drawer/QS menu slightly bigger

This fixes all of the minor bugs that can be fixed as well as some minor quality of life improvements. I will now be working on fixing up the camera and sensor and doing some basic housekeeping so supporting gvlte (SM-T677) will be easier in the future.

deadman96385 Thank you for not giving up, you are amazing! How did you fix Wi-Fi not working and system reboots compared to the previous marshmallow build you worked on. Was it tricky?

Should go without saying, but certainly hoping that this is lighter and faster than stock ROM
Let me load this up and Magisk and will tell you if works well!
