yeah the best one! do u have an app like Gsam to find out witch app suck on ur battery?
Yeah, I didn't even think to check it though.

Um, lemme give you my module list though. I've heard some modules made for older android versions don't work right anymore and might cause problems.

Awesome Pop-up Video
BootManager
CrappaLinks
Flat Style Colored Bars
GravityBox
MinMinGuard
Never Sleep
Statusbar download progress

Xstana
Youtube AdAway
DS Battery Saver

Any of these not work anymore? or just ones I should get rid of that aren't worth keeping? I honestly can't tell if half of these are doing what they're supposed to do.

Any modules you'd recommend I get?

Installed yesterday, everything works great but sloooow charging but very good battery life from what I can tell. The odd thin is I received a notification for an update from linage, so I d/l but not sure I installed correctly. Tablet came up after the flash, starting receiving "Image not Seanandroid" from a cold power on. Couldn't figure it out right away, and I noticed that SuperSU told me I wasn't rooted. So I reinstalled SuperSU from recovery and both issues resolved. Scary blowing away my stock rom, but I backed it up before I did. If anyone needs help let me know, I'll provide the steps I used. Great ROM.

Questions:
1. Do I need to keep the Zip files on my SD card? I have plenty of room just wondered
2. Anyone know how to get the google "touch to speak" bar to lay across the screen when in landscape mode (it shows up as a small icon to the left of the screen)? I does in portrait mode.
3. What app can I install on Win 10 to transfer files to my tablet? I can only do so in flash mode with twrp.

OK so I uninstalled all of the CPU acceleration apps and my battery drain issues stopped. The only thing now is the sirus app plays like chipmunks.

How to update to Marshmallow bootloader (required for 20170324 and later builds)
Updating the bootloader is very quick and doesn't wipe data or repartition the device.
If the last Samsung ROM you had was 6.0.1 Touchwiz, you already have Marshmallow bootloader and don't need to follow these steps. (If you were on MM, and it still won't boot, follow the steps below)

1. Download the bootloader-only Odin package: T800XXU1CPK2.tar.md5
This has the latest Marshmallow bootloader (December 2016)
https://www.androidfilehost.com/?fid=457095661767146298
2. Download Odin 3.11
You can skip this if you already have a working Odin
https://www.androidfilehost.com/?fid=673368273298937183
3. Shutdown your tablet and start it up by holding Power+Home+Volume Down to enter Download Mode. Volume Down is the one right next to the power button. Really shut it down and use this key combination, if you use Advanced Restart, or go into download mode via TWRP the bootloader won't change.
4. Make sure the screen of your tablet has a green android symbol with a "Downloading..." text
5. Open Odin3_v3.11.1.exe and follow the instructions in this image:
http%3A%2F%2Fi.imgur.com%2F2LpBdo2.png


If anything is missing, you WON'T flash bootloader successfully.
6. Click Start. Your tablet will automatically reboot back into your ROM.
7. To verify you have the new bootloader, you can run in terminal emulator "getprop ro.bootloader". It should say T800XXU1CPK2.

Thanks @ZakooZ for the post!

How can i do this step in Heimdall, I dont have a windows OS. I just have the samsung splash after flash and I am thinking I might be on older bootloader. thanks for any help!

Quick question, which is better, Magisk or SuperSU? And why?
Most people prefer Magisk for the following reasons:
- open source
- built in hide
- lets you install a large number of mods
- helps with SafetyNet

You should also consider Lineage's SU addon:
- specially created for LOS
- open source
- hide can be added (hide is called iSu and also helps with SafetyNet)

@DarkExistence Why add support for the fingerprint scanner if you said earlier that you do not do this because the presentations of the tablet go back ? And can you fix the automatic updates I have installed the latest official version of twrp and when updating yhe latest update is downloaded but not installed and then goes to the recovery without automatically installing.

Does the latest update support the fingerprint scanner? I am on that update, and I don't see that functionality. As for your question, Lineage OS just added a requirement that all official devices must support the fingerprint scanner, if they have one (they also added many other requirements). Perhaps that is why.

Because I also said at the time we are constantly looking at ways to fix things, and one of our members has successfully found a way to do so :)

No, i will post once added. Its being difficult for devices other then t805.

It is a requirement that all stock device features work on Lineage, unless proven unable to do so. We have an exception for the fingerprint however which was granted.

Was deathly auditor standard in this ROM for control? Mine now says app may not work because I'm not using deathly kernel.

Nope, it will not longer work correctly. There had to be kernel changes so that we were following guidelines and to make sure Lineage didn't cancel our builds. The updated official kernel no longer contains as many customisation options.

The unofficial builds which we build weekly still support deathly and all the customisation options it has.

You may flash the boot.img deathly if you wish to have the options returned, but thats up to you :)

First of all, a big thank you for this ROM that gave a second youth to my Galaxy Tab S! :good:

For installation, I followed the LineageOS WIki.
I've met some difficulties when following the wiki, here's my feedback:
- In "Installing a custom recovery using heimdall" section, after installing the custom recovery on download mode, you have to power off the device, but it isn't explained how. In my case, I had to hold for 20 seconds: Home + Volume Down + Power (you quit "download mode" like you boot into "download mode").
- In "Installing LineageOS from recovery" section, step 8, in my case, the microSD card wasn't located in /sdcard/ but in /external_sd/.

    LineageOS is a free, community built, aftermarket firmware distribution of Android 7.1.2 (Nougat), which is designed to increase performance and reliability over stock Android for your device.​

     * We are not responsible for bricked devices, dead SD cards,

    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 Official LineageOS 14.1 builds for chagallwifi (SM-T800) 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
    Have not attempted a clean flash

    http%3A%2F%2Fimg.imgland.net%2F_4JAwRZ.png

    First time flashing LineageOS 14.1 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)

    Make sure you have the Marshmallow bootloader. Guide is in the comments below.

    http%3A%2F%2Fimg04.imgland.net%2FAg8dlGr.png

    There will be a new build every week, every Monday.
    The builds will no longer be personally tested by me before being uploaded (but everything will probably be fine)
    Change logs will no longer be posted within every new build, but instead when the changes are uploaded to GitHub. I will try though to post changes for major bugs or fixes as they are released.
    Some builds might feature only minor changes, ie. only updating the LineageOS source
