Firmware updated to T713ZSU2AQA1 (downloaded from updato)

Then flash with heimdall

Note : on Archlinux, i had to use the AUR package "heimdall-git" (flashing didn't work with the community "heimdall" package, even if both package have same release number).

Most seems to work fine, except some wifi issues (sometime the wifi is lost and i need to hard reboot the device to have wifi back).

EDIT : frequent unwanted wifi disconnections / autoreconnection (annoying with Chromecast).

EDIT2 : LineageOS statistics doesn't mention country i am from. Because no SIM or is it an issue?

PS : i'am happy to have an official LineageOS release for the SMT713 - thank you to maintainers - but was not happy to have no more clear information about the required firmware update, simply announced on a post on this thread. This kind of thing need a clear warning on first post / installation wiki / how to, it is not very common.
[Galaxy Tab S2 Original Android Development] shilofax:
I'm considering purchasing this tablet. From what I'm reading the best thing to do would be to update it to latest official rom via ota, and then install TWRP and LineageOS. If I'm wrong, what would be the easiest way to install from brand new out of the box?
[Galaxy Tab S2 Original Android Development] SilverJS:
So does the fingerprint sensor work after all?
[Galaxy Tab S2 Original Android Development] Deltadroid:
It's the same as the T813 fingerprint scanner. Yes it works.
[Galaxy Tab S2 Original Android Development] SilverJS:
Beautiful! So, would users of this ROM say it's viable as a daily driver?

As an aside, suggest to OP (thanks for all your wonderful work!) fingerprint be added to the "Working" section of the original post, to minimize confusion for newcomers like me.
[Galaxy Tab S2 Original Android Development] pclewis:
Update

That would be easier than finding the new ROM, however the Chinese versions were all that were available when the LOS required them. There is supposed to be a Nougat version for the S2 rolling out OTA now, so I would wait on that. At that point the newer (3/28/2016 and later) versions will install. Only reason to do LOS is that it does not have Touchwiz and you can use TWRP. Also down the road, LOS should live on while Samsung drops the S2 updates.

I have had good luck with LOS so far, but I use Nexus and Pixel phones and want all my OS to look close to the same. LOS actually has a few things that are better than stock Android.
[Galaxy Tab S2 Original Android Development] bus-mt:
On updato.com you can download a Nougat image for UK (T713XXU2BQCO). After flashing this you have to update TWRP from here. But flashing lineage-14.1-20170411-nightly-gts28vewifi-signed.zip fails with error 7. It expects bootloader T713ZSU2AQA1, the nougat image comes with T713XXU2BQCO.
[Galaxy Tab S2 Original Android Development] SilverJS:
Sorry guys - really don't mean to be a pest, but am about to purchase this tablet because it's on sale. I realize I've asked before, but haven't received a reply - kindly request a quick one from a few users of this ROM.

The question : is this ROM viable as a daily driver? I will use the tablet to peruse the web, consume media (music mostly via Pocket Cast) and also, most importantly, to view PDF documents for work with XODO.

Thanks much!
[Galaxy Tab S2 Original Android Development] pcriz:
I'll say battery isn't as good as stock but but not by much. WiFi is more consistent.

Definitely fine for a daily driver.
[Galaxy Tab S2 Original Android Development] SilverJS:
Right on, thanks - much appreciated. For WiFi, you mean LOS is more consistent than stock?
[Galaxy Tab S2 Original Android Development] pcriz:
Yeah on stock my device was constantly dropping and reconnecting to WiFi.
[Galaxy Tab S2 Original Android Development] nickspiker:
Trying to install using TWRP 3.1.0-1_ashyx on my SM-T713 and I have a couple issues, I think it may be related to encryption but I can't even flash the ROM. Here's what I'm getting:

This package supports bootloader(s): T713ZSU2AQA1; this device has bootloader T713XXU2APK6.

Updater process ended with ERROR: 7

Failed to mount '/data' (Invalid argument)
[Galaxy Tab S2 Original Android Development] klm2349:
Go to twrp.me find sm-t713 device and download twrp 3.1.0-0. Flash that using Odin the same way as root was described in OP. You can then mount /data and format, install, etc.
[Galaxy Tab S2 Original Android Development] nickspiker:
Downloaded twrp-3.1.0-0-gts28vewifi.img.tar, which matches my device (SM-T713), flashed using ODIN3 v.3.10.7 under the AP tab, no reboot, straight to recovery.

Still can't mount /data, can't change the filesystem on it, repair it, or anything.

When I try and flash the ROM (lineage-14.1-20170418-nightly-gts28vewifi-signed.zip) it gives me the same messages...
[Galaxy Tab S2 Original Android Development] 0blivi0n:
You need to flash the below firmware first, then flash TWRP, do a full wipe (/system as well) and then Lineage:

https://www.sammobile.com/firmwares/download/124441/T713ZSU2AQA1_T713OZS2AQA1_BRI/
[Galaxy Tab S2 Original Android Development] nickspiker:
I would but I don't really want to sign up for a hosting service to download one file, do you have a link to a publicly available image?
[Galaxy Tab S2 Original Android Development] 0blivi0n:
Download from the below site, it doesn't require any sign up:

http://updato.com/firmware-archive-select-model?record=0F52FED6000C11E79215FA163EE8F90B
[Galaxy Tab S2 Original Android Development] joshnolt777:
So quick question. I have the t713 but it's the USA version, which doesn't have the aqa1 bootloader update yet and sammobile and update both don't have the update files. Would it be ok to flash a UK or Taiwan image then flash LOS? Thanks in advance.
[Galaxy Tab S2 Original Android Development] nickspiker:
Ok, so I've downloaded the above image, flashed it, then flashed the Lineage image, and it boots now, but it says something like 'data' is corrupt and it tries to keep wiping the data partition. I tried to manually wipe it, also format it as ext 4, repair it and change the size, no luck :(
[Galaxy Tab S2 Original Android Development] 0blivi0n:
Did you do a full wipe (Dalvik, System, Data and Cache) before installing Lineage?
[Galaxy Tab S2 Original Android Development] nickspiker:
Yup, and the odd thing is if I wipe everything, including system, but then reboot, it still boots to lineage and gives me the Encryption unsuccessful screen, no soft brick as you would expect.

Here's the logcat I get when I try and wipe everything except for micro SD card:

Could not mount /data and unable to find crypto footer.

Failed to mount '/data' (invalid argument)

unable to mount storage

etc.
[Galaxy Tab S2 Original Android Development] LuK1337:
Select data in twrp and change it's file system to ext4.
[Galaxy Tab S2 Original Android Development] nickspiker:
Tried that already, still unable to mount
[Galaxy Tab S2 Original Android Development] LuK1337:
Then twrp likely doesn't leave 16k for footer. Try manually resizing the partition.
[Galaxy Tab S2 Original Android Development] nickspiker:
Still no workie, but I actually chose 'Format Data' instead of going into advanced wipe and doing it there and it worked... Now I know :)

Thank you!
[Galaxy Tab S2 Original Android Development] pclewis:
Hmm, I thought I was doing something crazy, but Format Data worked for me too. I wonder if A1 is out in something besides Chinese?

Phil
[Galaxy Tab S2 Original Android Development] joshnolt777:
Did you try formatting your data partition in twrp? I had to do that because of encryption once. Click wipe and then format data instead of advanced wipe
[Galaxy Tab S2 Original Android Development] nickspiker:
Totally worked! Not sure why it didn't work in advanced wipe... kinda odd.
[Galaxy Tab S2 Original Android Development] joshnolt777:
Good to hear. From what I understand formatting data fixes the partition and removes any encryption on it while advanced wipe just erases it instead of removing encryption and formatting the partition.
[Galaxy Tab S2 Original Android Development] nickspiker:
Seems to be true but you would think it to be the other way around, thanks again!
[Galaxy Tab S2 Original Android Development] fiver5:
FWIW I got Heimdall built on Windows today. It is indeed a PITA.

If anyone else tries, here's what I had to do to get it to work in addition to what is listed in the README file in the win32

-use pacman to get the additional packages mingw-w64-x86_64-jasper mingw-w64-x86_64-toolchain

-run the cmake command from the top level build directory with . as the final argument, not from inside the build directory with .. as the final argument as in the instructions. There are some broken paths somewhere in the structure and cmake will barf looking for stuff if you run it from the build directory.

I didn't have to install any special drivers but I've flashed so many android devices from this machine in the past year that I already had the samsung ssusdbus.sys driver installed and that was leveraged.
[Galaxy Tab S2 Original Android Development] LuK1337:
Next week builds are going to require latest nougat bootloader / firmware ~ T713XXU2BQCO.

You can find it on updato or sammobile if you have 6 hours of free time lol.

~ Here's the command that will flash it using heimdall ~

heimdall flash --APNHLOS NON-HLOS.bin --MODEM modem.bin --TZ tz.mbn --SBL1 sbl1.mbn --RPM rpm.mbn --HYP hyp.mbn --ABOOT aboot.mbn
[Galaxy Tab S2 Original Android Development] orfik:
Good

Do you plan merge this to your rom? https://xdaforums.com/oneplus-3/themes/mod-aptx-codec-t3521228
[Galaxy Tab S2 Original Android Development] joshnolt777:
I have the usa model of the t713 and i havnt been able to find the usa nougat bootloaders anywhere. would flashing a different countries bootloader work? thanks in advance.
[Galaxy Tab S2 Original Android Development] LuK1337:
Yes, it should work as long as it's actually T713 and not some T713N or something. Anyway, don't flash anything right now, there's no build that requires N bootloader yet.
[Galaxy Tab S2 Original Android Development] joshnolt777:
Yea its not a wierd t713n just the standard t713 wifi model. Its good to know i can flash a different bootloader because when lineage updated the first time to require the aqa1 bootloader update or whatever it was i couldnt update lineage. Been sitting on the 3/21 build and ended up going back to stock
[Galaxy Tab S2 Original Android Development] LuK1337:
No clue what problem you had with just updating to AQA1 but whatever...
[Galaxy Tab S2 Original Android Development] joshnolt777:
Yea im not sure either tried updating with smart switch and that didnt update it to the bootloader i needed, and then i tried odin with firmware from sammobile and updato but still didnt give me the needed bootloader lol :confused: guess ill just flash the uk version thanks for the help.

need help flashing

hi guys, i am getting error 7. ive got a brand new t713 with the newest TWRP installed and rooted. i've tried to flash the most recent 3 builds and keep getting error 7. i did a factory reset first, wiped all the appropriate folders and formatted data already, but still no luck. any suggestions? i'm on bootloader T713XXU2APK6. no idea how to get a different bootloader. but i'm guessing thats what i need to do. thanks very much
[Galaxy Tab S2 Original Android Development] Lupin The Third:
You have a sketchy guideline in this very page.
[Galaxy Tab S2 Original Android Development] Deltadroid:
The current official build requires T713ZSS2AQB1 firmware, although, the next official build will need the firmware to be updated again to T713XXU2BQD1. You will also need a new version of TWRP to support T713XXU2BQD1 when it becomes available. When the next official nightly build is released for T713XXU2BQD1, I suggest updating the recovery (TWRP) at the same time you update the bootloader so you don't get a bootloop.

Edit:

The version of TWRP that you will need for the T713XXU2BQD1 firmware is 3.1.0-1, but do not update TWRP until the new nightly build is available. It will only work with the new nougat bootloader.
[Galaxy Tab S2 Original Android Development] LuK1337:
The twrp itself should work with MM bootloader.
[Galaxy Tab S2 Original Android Development] Fried Chicken Crap:
I was getting the same error, i figured out that they put the bootloader inside of the downloaded zip file if you got it from updato, at least that was the case for me
[Galaxy Tab S2 Original Android Development] 0blivi0n:
Flash the below firmware first:

https://www.sammobile.com/firmwares/galaxy-tab-s2-80/SM-T713/BTU/download/T713XXU2BQCO/128057/

Then flash the latest TWRP, and then wait for the next LineageOS build which will most probably be on 02-05-2017.
[Galaxy Tab S2 Original Android Development] Nbay64:
Quick question, will the next upcoming build support Vulkan now that our tablet has been officially updated to 7.0, which adds Vulkan support?
[Galaxy Tab S2 Original Android Development] LuK1337:
I believe that it was working from the beginning as we weren't using Samsung's adreno blobs.
[Galaxy Tab S2 Original Android Development] Nbay64:
Ah, ok. I haven't used this rom yet on my T713 so I wasn't sure.
[Galaxy Tab S2 Original Android Development] :
Hello :)

Today I clean flashed the latest build with only the Stock OpenGAPPS ARM64 package of today with it.

Unfortunately, when it says "Welcome to your SM-T713" and I tap "Set up as new" , it states "Setup Wizard has stopped".

Then, when tapping "Open app again", it returns back to the Lineage intro screen and the screens after are the same as before.

I also tried to "Copy your data", but when I do so, it skips the connect to wifi part, so I can't do that either.

So I guess the setup is missing the connect to wifi part (at least with the OpenGAPPS Stock package).

Can you please fix this? I would like to use my tablet again, haha :)
[Galaxy Tab S2 Original Android Development] Lupin The Third:
Gapps have been doing this with t813 too. Try to skip the gapps installation wizard and finish it after booting to system. Tap the screen in four corners of the wizard installation (not screen corners, but the installation box) starting from top left and continue clockwise taping four corners.

Otherwise, use a different gapps package, like beansgapps.
[Galaxy Tab S2 Original Android Development] Patrick907:
Thanks for sharing.

I downloaded the build and went into recovery however twrp can't read anything from internal storage? It says can't mount data and storage is showing 0mb.

I feel like I might be missing a step somewhere, is there a step by step guide I could reference?
[Galaxy Tab S2 Original Android Development] LuK1337:
It's encrypted, you got to format it in order to be able to read it.
[Galaxy Tab S2 Original Android Development] Patrick907:
Thanks for your reply.

i'm getting a error message that says the package isn't built for my build number t713xxu2apj1.

do i have to upgrade to the newer firmware first via sammobile, flash twrp, format and then try flashing this os again?
[Galaxy Tab S2 Original Android Development] BigBrosMo:
What did you learn when you read the previous posts before asking your question?
[Galaxy Tab S2 Original Android Development] HaloTechnology:
I know i shouldn't ask this but is the auto brightness ever going to be fixed ?
[Galaxy Tab S2 Original Android Development] sobhan06:
Hello All,

This OS model shares the same qualcomm spec with 719 right leaving LTE ?

So, hat will happen if I flash this ROM ? Any idea. I would like to try this OS.
[Galaxy Tab S2 Original Android Development] fiver5:
I had the same issue, you can also get around it by pulling down the notification quckbar and from there you can get into settings, force close setup wizard and then make sure it has permissions.

Although you will still have to flash Gapps again anyway, so it's better to just do it in sequence by first flashing the rom, booting up and going through setup and then after the tablet is in a base configuration flashing GAPPS and root. I had to learn that the hard way.
[Galaxy Tab S2 Original Android Development] pclewis:
USB File Transfer

I seem to have lost the ability to manage files with Windows. Same USB Driver. No errors in Device Manager, just cannot see the internal or SD card. Happened on update to 2017/05/09. I am not having problem with other devices on Lineage, just the Samsung S2.

I forgot to add that I upgraded firmware to T713XXU2BQD3. Before loading Lineage, the MTP worked and showed the Samsung S2 under Other Devices. After doing 05/09/2017, the MTP does not work and other devices goes to generic MTP.

Will try OTA of the 05/16 version and see what happens.

I am currently on stock firmware T713XXU2BQCO. To flash the latest nightly, am I okay or do I need to flash another firmware/bootloader first? Thanks!
[Galaxy Tab S2 Original Android Development] Deltadroid:
T713XXU2BQCO is currently the required firmware for the latest nightly build of Lineage. You are good to go.
[Galaxy Tab S2 Original Android Development] penguinjoe:
Initial Setup app crashes before system can be set up. System unusable.

What is your--

LineageOS version: 14.1 - 2017 05 16

LineageOS Download url: https://download.lineageos.org/gts28vewifi

Gapps version: open_gapps-arm64-7.1-stock-20170518

Did you--

wipe: YES - factory wipe

restore with titanium backup: NO - system not usable

reboot after having the issue: YES

Are you using--

a task killer: NO

a non-stock kernel: NO

other modifications: Root addon linked on OP

Provide any additional information (observations/frequency of problem/last version it worked on/etc) as needed:

Initial setup app crashes 100% of the time attempting to do a new setup (not the copy path which has no connection available).

As system can't be used in this state I have restored my working nandroid backup of TW T713XXU2BQCO.

Install order

ROM -> GAPPS -> Root Addon via TWRP install queue (no boot between each install)
[Galaxy Tab S2 Original Android Development] fiver5:
See bottom of pgs 16 and 17 of this thread. Try wiping and then flash just LOS. Then boot and go through guided setup. After setup is complete boot back into TWRP and install root/gapps
[Galaxy Tab S2 Original Android Development] Deltadroid:
You may want to try the Nougat base gapps package for 7.1.2 (arm64) that I posted here
[Galaxy Tab S2 Original Android Development] penguinjoe:
Thanks for the responses guys. I'll give both ideas a shot and up date this post with my results so others can benefit.

/Cheers!

--- edit ----

I tried a few things:

1. install LOS alone, allowed me to run thru the initial setup. Installing Deltadroid's gapps was a no-go - play store didn't like to work at all for me (play store services crashing).

2. install LOS alone, boot/setup again ok. Install root addon ok, install of open-gapps failed to install.

3. My last ditch will be to install LOS alone, setup, install original open-gapps (downloaded a newer build of them). Will update later on that.

---- final edit ----

The following procedure works for me:

1. install LOS rom only. Don't install gapps.

2. Boot into system - run initial setup. Works. Reboot to recovery when finished.

3. Install open gapps from link in OP. I used the drop from 5/22/17

4. Boot into system. Let it settle.

5. (optional if you want root) Reboot to recovery once finished. Install the root addon.

This all seems to work ok. I have some issues with the gboard that is installed - it crashes when trying to set it up (I look at that as a gapps issue not a rom issue).

Thanks go out to Deltadroid and fiver5 for their help

Thanks. It's great to have a proper version of TWRP.
[Galaxy Tab S2 Original Android Development] wirelesskebab:
No love for 2015 versions on TWRP site :(

it works with T719, so thank you :D

[Galaxy Tab S2 Original Android Development] jshamlet:
It also works with the T813. Great to have a real recovery on this device. :)
[Galaxy Tab S2 Original Android Development] radiocarbon:
Ever since TWRP 3.1.0-0 twrp can no longer read my encrypted data partition probably due to commit f628cbfc5e77a3a358c95ef7f1e47bbb1505b9d0 on the TeamWin github for the gts28vewifi (I can't post the direct link because my account is too new).

Is there any reason the encryption blobs were swapped out and how would I go about getting twrp to read my encrypted data partition again. I've already tried wiping everything, reflashing and reencrypting but it didn't help.
[Galaxy Tab S2 Original Android Development] LuK1337:
I am on it.
[Galaxy Tab S2 Original Android Development] Deltadroid:
Actually, I think the issue with decryption is with qcom_common. The following commit is needed (which exists on the android-7.1 branch): https://github.com/TeamWin/android_...mmit/c4dab0d6d73f05b70091761e536b751dc9328f49
[Galaxy Tab S2 Original Android Development] LuK1337:
Please try latest ( 3.1.1-1 ) build.

It works now, thank you very much.
[Galaxy Tab S2 Original Android Development] Alpha1BA:
Hi, would this be compatible with gts210veltexx
[Galaxy Tab S2 Original Android Development] LuK1337:
No, T813 recovery probably is.
[Galaxy Tab S2 Original Android Development] AndyYan:
Hello, think I need some help with setting up this particular tab... None of the recovery images listed on the official site (plus the unofficial one here) work properly. Any 3.1.0+ one would say "Failed to mount /data (invalid arguments)" and not show me my internal storage and data (shows /system and SD card alright though), and lower version ones would just boot to TWRP splash screen then reboot, without getting to the main menu. I'm running the latest Nougat update (T713XXU2BQD3) if that matters.
[Galaxy Tab S2 Original Android Development] LuK1337:
You can't mount data if you come from stock. It is encrypted and twrp doesn't support it so you got to format it to ext4 in order to mount it.
