Well I would FORMAT /data and not wipe it because with a high possibility it's encrypted and TWRP will throw many errors at you on first start failing to mount it. When this is done, reboot TWRP (this time without the mount errors) and THEN wipe /system (here a wipe is enough) and flash LOS and your Gapps. When this is done, you can wipe your Cache and Dalvik and install Magisk WITHOUT any additional reboot. 4G should work fine. At least last time I used it.

Hello everyone

Meri [MENTION=1992533]emuandco[/MENTION] for your answer.

I followed my method above and I had no errors when installing from TWRP twrp-3.2.3-1-gts210ltexx

On the other hand a little disappointed, this version of LineageOS, is not totally compatible with the SM-T819 and offers can of interest compared to the ROM Stock T819XXU2BRI1

Being Root with Magisk v18.1, it is better to freeze unnecessary applications with MyAndroidToolsPro.apk.

As much LineageOs 16 build 16 on a Galaxy S5 brings a real plus and totally compatible on this old samsung as much on the SM-T819 is the flat calm.

This is only my user opinion, everyone can make his own experience.
[Galaxy Tab S2 Original Android Development] emuandco:
Nr 1: https://dl.twrp.me/gts210velte/ this is yours and not gts210ltexx. If you flashed the wrong one, you are lucky it did not cause mayor problems.

Nr 2: What are you missing feature wise? This is a LOS 16 as for every other device too. Same stuff, same features, all the same. Only feature I know is missing is incall audio. Did you forget installing OpenGAPPS?
[Galaxy Tab S2 Original Android Development] Montero7o:
Hello [MENTION=1992533]emuandco[/MENTION]

Excuse me, it's the version "twrp-3.2.2-0-gts210velte.img" that I used and is active on my Galaxy S7 Edge.

For Gapps I used "open_gapps-arm64-9.0-pico-20190309.zip"

What I miss most and that is unusable in the state is the camera function.
[Galaxy Tab S2 Original Android Development] emuandco:
Well, camera works for me. Only difference, I use STOCK GAPPS always, but PICO should be fine enough for a camera app, too. Never heard of a camera problem in T819/T719/T813/T713 the last months

hi dev, i found a bug in rom lineage-16.0-20190308_141803-UNOFFICIAL-gts210velte, that is a bug in the hotspot if the hotspot is turned on to work normally then the hotspot is turned off there is no response then the dead device and restars themselves, can it be fixed? thank you dev
[Galaxy Tab S2 Original Android Development] dantibes:
hello I wanted to inform you that I tried the new rom, version of 20.3.19 and I realized that by activating from the settings the display function - automatic brightness the tablet keeps restarting. if you need some feedback considering that I am a neophyte and have little modding experience I ask you to detail the files and the modalities to follow to send you my feedback. thank you

hi dev, I found a bug again in lineage-16.0-20190320_212438-UNOFFICIAL-gts210velte, a bug I found in the problem of setting the big little kernel CPU, I used the ex kernel manager application there I saw a problem in the big little cpu like the initial max cpu -1 mhz after changing to 1801000 mhz, min cpu cannot be changed to 400000 mhz, is there a problem in the kernel dev and can it still be fixed, thanks.:good:

Hello everyone, hello [MENTION=5075128]LuK1337[/MENTION]

Bravo [MENTION=5075128]LuK1337[/MENTION] for the work done on LineageOS 16 for the Samsung Galaxy Tab S2 tablet SM-T819 LTE

I read all the pages of this tutorial https://xdaforums.com/tab-s2/orig-development/rom-lineageos-16-0-t3838617 to install LineageOS on my SM-T819 without problem.

In the LineageOS roms repository, there is a new version lineage-16.0-20190410_152744-UNOFFICIAL-gts210velte.zip here https://androidfilehost.com/?fid=1395089523397937948, but the downloaded file is lineage-16.0-20190410_152744-UNOFFICIAL-gts210.zip, it is missing "velte" in the file name.

Is this a new version compatible with the SM-T819 and can I install it?

Thank you for your answers.
[Galaxy Tab S2 Original Android Development] ariegeh:
sorry@luk1337, I have tried installing lineage-16.0-20190410_152744-UNOFFICIAL-gts210velte, it turns out it's still the same problem as yesterday, the problem in the biglittle kernel at the start max cpu -1mhz then changed to 1801000 no problem then min cpu cannot be changed to 400000 mhz I use the ex kernel manager application, then at the hotspot if the hotspot is turned on to work normally then the hotspot is turned off there is no response then the device turns off and restarts itself and the problem in auto brightness. conclusions rom lineage-16.0-20190410_152744-UNOFFICIAL-gts210velte is just a security patch update, sorry yes dev luk1337 is only a participation I have tried this rom, thank you very much for developing this rom, okay please dev luk1337:angel:
[Galaxy Tab S2 Original Android Development] jerome_m:
I installed the latest version yesterday.

I was using a tab S with Lineage 14.1., no gapps. I found a cheap S2 and this was the only version of lineage I could install.

To install twrp, I used heimdall on ubuntu. It was a bit involved as a newer version of heimdall is necessary than is available for unbuntu. You will need 1.4.2.

After twrp boots, use the "advanced" menu and reformat the "data" partition. That will get rid of the red warnings in twrp and avoid lineage booting into a loop.

The rom appears to work generally fine. I am not using any google stuff, just f-droid and aptoide for the "brave" browser.

Some fdroid applications do not work correctly. I am not reporting this as a bug, because I think it is a problem with android 9 and not with this particular rom. For example:

-icecat browser seems confused on some sites that worked with lineage 14.1 on the tab S.

-wlan browser cannot access the wifi

-maps needed a reboot to be able to download its basemap and start.

There are a few other problems I noted:

-I use a 128GP SD card. Capacity is reported as 256GB with 128 GB reserved to system (probably an artefact of the way it is partitioned?)

-each boot, the tablet complains that the SD card is missing and should be re-inserted, but it still works without any further doing.

-my fingerprint is never recognised

-I installed 3 languages, English being the default. Normally, apps should display their data in English, but they seem to choose one of the 3 languages somewhat randomly.

-the built-in video player does not work very well: video freezes regularly. The same videos play fine with vlc.

-I leave the tablet to charge at night. Often, I get a message in the morning that wifi watchdog was triggered and problem was fixed by rebooting.

I have tested the radio with two different sims on 3G and 4G. Data works. I tried to call one of the sims (in 3G): the tablet rings, I can pick up the call but there is no sound either way. Not complaining here (it said here incalls would not work), just trying a few tests in the hope they would be useful.

orbot causes reboots

With lineage-16.0-20180905_013739-UNOFFICIAL-gts210velte, I've found that using orbot (via orfox) for a short time will cause the machine to reboot and get stuck in a boot loop. The machine has to be left unbooted for some time before it will boot properly again. To get the machine to stop trying to boot you have to plug in the charger, wait for it to get to the charging screen during boot and then unplug the charger.
[Galaxy Tab S2 Original Android Development] dantibes:
hello everyone, I wanted to know if someone has happened that outdoors and then with a lot of brightness when you open some apps the tablet restarts and therefore does not work. until being forced to restore a previous backup of another rom. some clarification on the matter thanks

Edit: unfortunately the last Rom of June 21 also presents the same problem.
[Galaxy Tab S2 Original Android Development] emuandco:
I use mine for Pokemon Go aka very outside and never had that problem O_o
[Galaxy Tab S2 Original Android Development] dantibes:
Hi I would not like to be or appear rude. however I have tried all the updated roms and after an encouraging initial operation random reboots occur on the outside with so much brightness. If you want let me know step by step what you need to solve the problem. thank you
[Galaxy Tab S2 Original Android Development] emuandco:
No clue why you have that problem. How about flashing the NEWEST official firmware first to get bootloader and firmwares up to date and then reflash LOS?
[Galaxy Tab S2 Original Android Development] solved:
so, may i ask .. is there an improvement with this rom for you all? i mean, usually i running on latest stock version with this tablet, i tried LOS a week ago but i switched back coz of the unusual heat while playing games and watching netflix. but those things are workin under the stock rom without any issue oO

I just wanted to know if u feel a real difference to stock rom, with lineage? something worth to do the "reflash"

Thanks

Hi guys,

Can someone tell me why build-in back up doesn't work at all. Thanks in advance.
[Galaxy Tab S2 Original Android Development] jerome_m:
There are a few problems I noted with this rom:

-I use a 128GP SD card. Capacity is reported as 256GB with 128 GB reserved to system

-this may be related: files copied from the tablet to an USB stick via USB-OTG are twice to big and apparently padded with zeros.

-my fingerprint is never recognised

-the built-in video player does not work very well: video freezes regularly. The same videos play fine with vlc.

-I leave the tablet to charge at night. Often, I get a message in the morning that wifi watchdog was triggered and problem was fixed by rebooting. Alternatively, wifi does not work the next day and I need to switch it off and on again, then reconnect.
[Galaxy Tab S2 Original Android Development] wetzer123:
As I have a bit too many reboots I tried to do this. I downloaded recent stock from sammobile (I got a 1 file version) and installed it via odin. But it leaded only to bootloop, so I installed twrp via odin and restored my los backup. I tried it with german and british stock version, both the same outcome.

What am I possibly doing wrong with the installation of stock?
[Galaxy Tab S2 Original Android Development] mikael199:
Hi guys,

I found a problem with this rom.

now I replace the car radio with the tablet, and I use a miracast dongle (because our tablet don't support the MHL) for stream the audio to a processor.

with this rom, when i tap the smart view function, the tablet find the miracast dongle but if i connect, it crash and restart.

with another rom the tablet connect without problems.
[Galaxy Tab S2 Original Android Development] pitrus-:
Perhaps this could have something to do with the fact that Google is dropping wifi direct support for legacy devices like this tablet, as Miracast is actually a wifi direct feature.

[Galaxy Tab S2 Original Android Development] emuandco:
Some logs might be useful. If anyone can fix it... maybe, maybe not. That's the problem when Samsung device support is crap. My last Samsung ever that for sure. This ROM made it possible to at least have Pie for it, but the costs are some nitpicks, like this Miracast thing I guess, phone audio and the well known battery below 45% == reboot at least once just to work afterwards again...
[Galaxy Tab S2 Original Android Development] sam_khan:

[Galaxy Tab S2 Original Android Development] emuandco:
I did so in the past too and it did not bootloop. You need to wipe /data btw. If this fails I have to check what files you have to kick outta the update to only update Modem and BL.
[Galaxy Tab S2 Original Android Development] emuandco:
Small sidenote. LuK1337 seems a bit busy these days, so I post it here. After I asked [MENTION=6005084]ripee[/MENTION] if he is fine with posting the link.... here are some more recent builds made by him: https://drive.google.com/drive/folders/1VsHc9-k4LA3-n19dp6Gkvqwf0GZLTRcA

What to expect:

New patchlevel

New fixes included to LOS16

What not:

All known bugs are still there. No phone audio! Sometimes strange reboots! Looks like NO Miracast!
[Galaxy Tab S2 Original Android Development] wetzer123:
Thank you for this reply. I will check within the next days and write how it is doing.
[Galaxy Tab S2 Original Android Development] wetzer123:
I have just tried.

I booted to recovery and did a wipe of data. Then I applied stock rom via odin, I had a single file rom named:

T819XXS2BSG1_T819BTU2BSD1_T819XXS2BSG2_HOME.tar.md5

After reboot there came some installing and then it sayd only samsung on black background and stayed there for about 20 minutes till

I finished this and instaled twrp via odin and then did a twrp restore, so at least my backup strategy is fine...

So it woul be great if you would have an advise how to proceed better.
[Galaxy Tab S2 Original Android Development] emuandco:
Hmm... Strange it is... I used another tool TBH, but this should not be a problem... https://xdaforums.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647/amp/ deprecated it not. It works fine over here. Be sure to install the correct country code btw. Download mode Odin in as new as possible and set.
[Galaxy Tab S2 Original Android Development] wetzer123:
I now downloaded a 4 file version via SamFirm and I will give it a try this weekend as it always takes some time for backup and preparation to do so.
[Galaxy Tab S2 Original Android Development] emuandco:
I always use the encrypted 1 fine version, but feel free to try. Strange problem it is... I never had such problems.
[Galaxy Tab S2 Original Android Development] wetzer123:
Now with the 4 file version it worked (and I did nothing different as the other times...) but fine. System came up with original

fw security level August 2019.

I was not shure what to do then. I reinstalled twrp and did a rerstore of my saved configuration. Or would I have to do a clean install of LOS?
[Galaxy Tab S2 Original Android Development] pitrus-:
You will definitively have to do a clean flash from Samsung ROM into LOS.

How can i fix ist?

Same here, after installing stock rom and trying to make a clean install of LOS, so I went back to my twrp backup of LOS.
[Galaxy Tab S2 Original Android Development] emuandco:
It never was a good idea to force check the bootloader. If someone is too dumb to update it before flashing a custom firmware... Natural selection that is! OK. ppl with install problems due to newer bootloader, do this:

Load the newest build by ripee https://drive.google.com/drive/folders/1VsHc9-k4LA3-n19dp6Gkvqwf0GZLTRcA

Open with 7-Zip.

Go to META-INF\com\google\android\ and extract/open updater-script in a editor like Notepad++.

Remove line 2 of the script. (assert(samsung.verify_trustzone etcetc)

Repack back inside and overwrite the current script.

My work on Q (no builds yet but the sources are coming along)

As for in-call audio on Pie, luk1337 has stated that he's looked over many logs and can't find the problem. In fact this is the one bug that kept T719 and T819 from getting official Pie support, unlike T713 and T813.

I got carried away with working on the qcom Note 4 (apq8084), whose progress is slow and steady now that it boots. But I'm learning more and more about debugging so that the standard set of Q commits that msm8976-common needs won't be a problem to merge.

Lineage merged the msm8952 CAF commits, which msm8976 uses, so there's no more need to repopick anything to get it to build. I've gone through some of luk1337's gts4lv-common commits for the S5e; once I pick whatever is applicable to msm8976, I'll turn my attention to msm8974 (S5 and Note 3). Once all those are picked, it should boot. Then we debug from there. I'll have time this coming week to focus more on msm8976. :good:

Anyone has problem with fingerprint reader on lockscreen? If you lock the screen and turn it on immediately, it works, but after a min or two of the screen being turned off/locked, the only way of unlocking is the password. The fingerprint sensor simply does not work or react until the screen is unlocked. I have this problem with ripee's build, pitrus-'s builds and even a build I have compiled myself. I have had this problem with LineageOS for at least a year or two and it always made me go back to stock. However now, without security updates, I don't really have a choice...

I have also tried pitrus-'s lineage-17.1-20200316-UNOFFICIAL-gts210velte.zip, but that is stuck in bootloop - to be expected, that is just an pre-alpha / test build / whatever.
