[ROM][7.1.x|SM-T900| Unofficial LineageOS 14.1 (v2awifi)

thompatry · Dec 24, 2016

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

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!

I would not recommend dirty flashing from CM-13.0 since this is a major OS change. Also something to take into account is that some apps are not ready for N yet.

vochong · Dec 24, 2016

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.

Best regards,
Eric

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 ?

Awesome Xmas present. Running smooth. Thank you for keeping my favorite tablet my favorite tablet!

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
I feel the force is strong with him

Whoever ca do this can build a Death Star too :laugh:

Really great work, never dared to dream of gettin Nougat on this rom and now. Just great work. Thx a lot and merry christmas!

This firmware already rooted, you only need enable root in developer settings

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.

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!
