LineageOS is a free, community built, aftermarket firmware distribution of Android 7.1.* (Nougat), which is designed to increase performance and reliability over stock Android for your device.

Code:
#include <std_disclaimer.h>

/*
 * Your warranty is now void.
 *
 * 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.


Important information:
This thread is for Unofficial LineageOS 14.1 (v2awifi) ROM for the Samsung Galaxy Tab Pro 12.2. The following will not be supported here:
  • Custom kernels
  • Mods
  • Xposed

Do not ask for ETAs. If you do, I will ignore you and your post.

SEANDROID ERROR
  • If you see a message at boot about Recovery or Kernel is not SEANDROID Enforcing, you can ignore it. This is just telling you that you are not running Samsung stock software. It has no effect on recovery or the ROM itself nor related to either.

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

Bootloader Information
You need to make sure you have a Lollipop bootloader installed or else your device won't boot. Here you can go grab the latest bootloader and odin and flash it in download mode. Read all the steps before you do this.

Make sure you have a full backup because just in case you something fails.

Here are the steps to flash this via ODIN:
  1. Make sure you have a full backup because just in case you something fails. Here are the steps to flash this via ODIN.
  2. Reboot your tablet into download mode. Do this by first switching off the phone, then pressing and holding the volume down + home button together and then pressing the power button. Press volume up button to enter download mode.
  3. Open ODIN on your computer. You?ll see the ID:COM box turning yellow with a COM port number upon successful connection with the tablet.
  4. In ODIN click the BL button, select the bootloader firmware. It's a tar file.
  5. Make sure Auto Reboot & F. Reset Time options are selected in ODIN
  6. Click on the start button. When the process is completed your phone will reboot.

Installation
  1. Download the zip(s)
  2. Install a compatible Recovery (This will not work with the P900 recovery)
  3. --I have built a new version of TWRP with the MM kernel. MTP, Vibations, ADB now work and there are performance increases. Link
  4. Perform a nandroid backup of your current ROM (optional)
  5. Wipe data/factory reset
  6. Flash LineageOS
  7. Install the Google Apps addon package (Optional)
  8. Reboot

Root
The SU root binary is no longer installed with ROM by default. If you would like to install root, please go here and download the binary.

Issues?
Before posting in this thread, make sure of a few things:

  • You used the search function of the forums
  • If you are the only one having a problem. Boot into recovery, wipe data/factory reset, reflash the rom/gapps and nothing else. Boot up and see if the problem persists.

Downloads
The app can be found in the Play Store:

Helping the developers
You may have noticed there's 2 versions of this app, one ad-free for donators and one with ads.
You can help us by clicking ads you're interested in for the free version, or purchasing the donator version!
We will use the money generated by this app as common money for the developers of the team. It will be used to pay for our web-hosting (we own a gerrit server and a domain name, exynos5420.com). It will also be used to buy a new device if one of ours breaks.

Translating the App
You can also help us by translating the app to your language:
1. You can start by looking at the full english language file: Link
2. Then compare it to your unfinished language file. You can find it here, under values-xx/strings.xml, xx being your language abbreviation.
3. You can then fill-in the missing strings in your language file. Here's an example of what a proper update looks like.
4. Then you can submit your translation by using our gerrit. If you don't know how to use gerrit, just PM the translation to your favorite developer and he'll get it merged!

Haha again I'm the first to make a post whenever Thompatry releases a brand new ROM.
Thank you very much!

Merry Christmas and Happy New Year 2017 to you and your family.

Finaly, a working Nougat for the awesome tab pro.
Love this tablet but the support from samsung is terrible. Stuck in 4.4 Kitkat and the tab deserves an better version.
Had a working Lollipop but it was buggy like hell.

This release is working perfect, and above all, its fast and smooth.
Nothing like the buggy Lollipop.

Keep up the good work, love this release and Marry Christmas to everyone.

So far working pretty well, but I'm not having any luck getting the SD card write fixes to work. I got them to work on M. Anyone have any suggestions?

What do you mean of write fix ?
I'm having no problem with the sd card. I can use my card as internal or external storage.

Are you using a fat(32) or exfat formated sd card ?

Here is a quote from
HTML:
https://twrp.me/devices/samsunggalaxytabpro122exynoswifi.html
"Download the latest TWRP image file (.img) from the download link and boot TWRP. Go to install and find and select the Images... button. Browse to the image that you downloaded and select it. Choose recovery and swipe to flash."

Should work :)
@thompatry

Hi @dialbat

It is highly recommended you have 3.0.2-0 or higher, whilst you could still do it on your version more than likely, I would not recommend it as the later version have more advanced options that one should consider using, especially in the wipe department.

Just keep in mind that any recommendations that you see in the initial post, it is more than likely because during the testing period before release, we may find certain procedures, bugs or operational matters that are reflective on the versions of systems we are using, and thus we always look at the best possible recommendations, typically this avoids heavy amounts of repeated questions and repeated issues.

Cheers,

David.

yes, figured it out :)
Hi @dialbat

Just note if you install any other SU system it might claim that it is out of date, whilst this might be the case installing any other SuperSU system may interfer with the one it comes, and unless you need any crazy functions, the default one is pretty good.

Might be a useless bit of info, but I spent hours working on this to see what was optimal, and no matter what I landed back at the built in one for convieniance and usability [emoji2]

Cheers,

David.

CM14 first impressions. Clean install, big wipe, nano Open Gapps, all new app installations. Sound is weak and "OK Google" doesn't work as advertised. Play Store hiccoughed and then froze the tablet but reboot fixed it and no further glitches. Hangouts still will not send a text as with CM13.

Otherwise, as I have been adding and testing more apps, I have not found any problems. It seems amazingly smooth and stable. WiFi and BT are good. Citrix receiver works like a bomb. Haven't found an app yet that doesn't play in the sandbox with Nougat. File explorers and Titanum read and write to extSD1 out of the box. Love dual screen. Mouse works great with arrow and no more blue circle. Seems like this is easily a daily driver from the first release. Goodby CM13, I used to love you but now have a new friend.

Merry Christmas to us all!
