First update to latest Samsung rom which has the correct bootloader ;)
[Galaxy Tab S2 Original Android Development] bavmouse:
Where can I download this?
[Galaxy Tab S2 Original Android Development] LuK1337:
Next build will support that one. Ty for reporting~
[Galaxy Tab S2 Original Android Development] RagingHarry:

[Galaxy Tab S2 Original Android Development] caprihome:
What about T819XXUU1BQF2?

Will you also support it?

thank you.
[Galaxy Tab S2 Original Android Development] LuK1337:
Yeah, that's N too.
[Galaxy Tab S2 Original Android Development] RagingHarry:
Well I managed to run into big trouble, did the upgrade, installed magisk 15.2 again, everything seemed just fine

thought a few hours later, might want to try to install viper4arise again in choose to boot to recovery fom the menu.

Bam see attachment, cant boot to bootloader but odin wont flash anything anymore....

Hmmm forgot i found a .pit file before and am reformatting at the moment, install via odin went fine, now in stock recovery agian.

Gonna flash fresh with latest build and magisk 15.3 stable now to see if that works properly.

But back on the track to run my 819 again.

Damn I hate that this piece of sldfjoiewrjulksdjjr lacks fastboot

[update1]

Seems to be in a bootloop after installing stock firmware for now, doing the process over now and then wait longer to see if it finally will pass the android is upgraden screen with the white slider and then auto reboot to go there again, It seems that it needs to complete that process, otherwise no option to go into stock recovery and to a factory reset or that kind of stuff.

and to be able to get twrp running again I seem to need that stock needs a full boot.

[update2}

While in the bootloop at the 2nd attempt, went to download mode again and from there used the direct recovery keys volup instead of down and could factory reset it, now booted to stock 7.0 T819XXU2BQI1_T819PHN2BQI1_T819XXU1BQHD_HOME.

Now install twrp, and constantly end up in

<ID:0/008> Firmware update start..

<ID:0/008> SingleDownload.

<ID:0/008> recovery.img

<ID:0/008> RQT_CLOSE !!

<ID:0/008>

<ID:0/008> Complete(Write) operation failed.

<OSM> All threads completed. (succeed 0 / failed 1)

On screen after flashing twrp last 2 lines are:

SECURE CHECK FAIL : recovery

Çustom Binary(recovery) Blocked by FRP Lock

Don't know what to do atm, out of ideas, if there was fastboot it would be way more simple.....

[update3]

OMG beginners fault, that was a long time ago, freakin OEM unlock, did that only 2 hours after buying this piece of crap, REALLY

[UPDATE4]

Booted just into Los 15.1 last build, booted to recovery/twrp also working fine.
[Galaxy Tab S2 Original Android Development] bavmouse:
okay, than I will wait for next build!
[Galaxy Tab S2 Original Android Development] Ferrum Master:
Booted fine. Installed gapps after the second boot, albeit can't get market running, google framework crashes. New build coming came this morning, will report later.

The thing is a bit sluggish, or is it me?

[Galaxy Tab S2 Original Android Development] mick154:
Can't get this to work because of wrong boot loader, boot loader for t819xx this is t819y. any chance this bootloader will be supported please.

T819y is gts210velte
[Galaxy Tab S2 Original Android Development] mv54:
Does this have the spectre meltdown patches and does it work with t810?

Welcome in the funny world of Alpha state GAPPS ^^
[Galaxy Tab S2 Original Android Development] RagingHarry:
open_gapps-arm64-8.1-pico-20180108-UNOFFICIAL worked good for me
[Galaxy Tab S2 Original Android Development] RagingHarry:
Just wondering, are we constantly getting dailies, or are there that much chances atm, cause on github(the device specific on the *-dev) I don't see that much that it should be daily updates.

I really like the daily updates, but could they be ran together with a changelog.sh so it would be easier for us to know what's been done as what to react to.

Since this wonderfull support started, which we all appreciate really Big, me for sure, we have to visit a few different sites to get info, but those are for multiple devices and android versions.

Adding a changelog.sh to the build script is rather easy, and would provide us very much info, also would it make it easier to comment on a problem we as users find if we can find what's changed more easily, that would make it easier to give detailed info on a problem we find/experience.

Please read this as a very polite request, please.

I know that LOS 15.1 isn't official or gonna be for our device, but getting info from cmxlog and only a all device timeline and no dates make it hard to read atm for what changed for this rom/build, but using a changelog and make it copy that also to the same AFH account directory would make it far more easy for us to help.

For another time, I know we're not supposed to ask or demand, you guys do this because you love to, and we love to help if we can!

This is just a suggestion that came up to me.

If you don't like it please ignore!!!
[Galaxy Tab S2 Original Android Development] bavmouse:
with today's ROM update I was able to get the 8.1 gapps up and running.

unfortunately the recovery of the apps with titanium backup does not work.
[Galaxy Tab S2 Original Android Development] mick154:
Thanks for y variant support , very much appreciated
[Galaxy Tab S2 Original Android Development] emuandco:
Titanium Backup caused me so much trouble in the past that I did not use it anymore for two years now.
[Galaxy Tab S2 Original Android Development] bavmouse:
What do you use instead of Titanium?

It makes only Problems with AOSP ROMs, no Problems with Stock ROMs. I don't know why!
[Galaxy Tab S2 Original Android Development] emuandco:
Me? Nothing. I have all my login data I need for plain resetting up all apps I need. Google knows what apps I used before and I can install all of em. Adding a few login data is no reason to use some questionable backup solution IMO. If needed I have all apps back running in about 90 min.
[Galaxy Tab S2 Original Android Development] bavmouse:
the ROM works very well for me so far. but I can't access my sd card either with solid explorer or with the ES explorer.
[Galaxy Tab S2 Original Android Development] Ferrum Master:
No problems here. Do you use root? Magisk?
[Galaxy Tab S2 Original Android Development] bavmouse:
I use Super SU
[Galaxy Tab S2 Original Android Development] emuandco:
Magisk ftw
[Galaxy Tab S2 Original Android Development] Ferrum Master:
I have a shutdown as soon RIL kicks in on the latest 17th build. Back to 15th.

Anyone else, or should I do a clean install?
[Galaxy Tab S2 Original Android Development] mick154:
Same shutdown with clean flash back to 15th as well
[Galaxy Tab S2 Original Android Development] LuK1337:
Useless posts. You gotta post logs if you want to be helpful in any way.
[Galaxy Tab S2 Original Android Development] bavmouse:
Same by me, also with clean flash!
[Galaxy Tab S2 Original Android Development] emuandco:
Your heard what LuK1337 said, didn't you?! LOGs OR DID NOT HAPPEN! I can't and won't flash every daily build to kill my tablet in 6 months due to killed NAND, be sure about that!

This is XDA and no retail product forum of Samsung. Here we are devs or testers, no 100% only useres.
[Galaxy Tab S2 Original Android Development] LuK1337:
It won't kill your NAND that fast.

[Galaxy Tab S2 Original Android Development] LuK1337:
Never.
[Galaxy Tab S2 Original Android Development] EiNESTEiNi:
So is there anything I can do to get the tablet to use a different bootloader, maybe flashing T819 Lightning ROM from XDA?
[Galaxy Tab S2 Original Android Development] LuK1337:
Flash latest 7.0 stock rom with heimdall / odin.

PIP settings are available as on any recent LOS ROM. If the app uses it or not is up to the app.
[Galaxy Tab S2 Original Android Development] Cyanogengod:
Hey guys, I have just successfully installed yesterday's release of this rom on my t819.

Few bumps along the way though. Basically just had to flash the Stock 7.0 firmware first, in order to get the compatible bootloader and edit the gapps installer.sh as described in the other post.

Everything works great so far and I have only been able to find one minor problem.

.)Longpress on the home screen to bring up the Wallpaper/Widget selection stops working at some point after a fresh boot, presumably after opening multiple apps, for no apparent reason.

I am also going to attempt to build my own version with the guide that's been provided.

Thx for the great work devs!:good:
[Galaxy Tab S2 Original Android Development] Cyanogengod:
Could you test the long press on home screen to bring up Widgets/Wallpapers after 5 minutes of use?
[Galaxy Tab S2 Original Android Development] RagingHarry:
Works just fine for me
[Galaxy Tab S2 Original Android Development] Cyanogengod:
Which version are you using?

There is literally a new release every single day, but without change logs, thus I never have a basis to make a decision upon whether the next update is necessary, hence there is no choice but to flash them all.

You guys really did a fantastic job, but would it be possible to include minor change logs, as there are literally daily updates?
[Galaxy Tab S2 Original Android Development] BARTVERSTRAETE:
Hi guys

why is the miic and speakers during a call not working, is it because samsung bixbe? Hope you guys can fix it soon, I use the tab as my phone as I am visually impaired.
[Galaxy Tab S2 Original Android Development] emuandco:
Changelogs are a bit spread around:

https://github.com/gts210vewifi-dev

https://www.cmxlog.com/15.1

Well, because no one found out yet why everything is silent coming from RIL. And right now no one has a clue how to fix it. Btw, this is the reply for our Spanish guy above, too :P
[Galaxy Tab S2 Original Android Development] Cyanogengod:
Thanks, so your releases do not overly differ from the official ones, apart from compatibility modifications?

Also, I know it is only officially supported on 14.1 LOS, but do you think the Boeffla Kernel would be feasible in the future? I'd like to volunteer to help with a port.
[Galaxy Tab S2 Original Android Development] emuandco:
You are free to port over if you want, but these are as much as possible unmodified LOS builds and will stay that way. Aim is that these will become official sooner or later (hopefully with call audio...). But as always, everyone is free to use whichever kernel he likes ^^
[Galaxy Tab S2 Original Android Development] Cyanogengod:
I'll get to work right away, there aren't many core changes in LOS 15 anyways

I just ran a couple of benchmarks on a fresh install of yesterday's release and I am a little concerned with hardware optimization as the scores are quite below those of the Stock Samsung Rom which cannot be.

The CPU scores are ok, but the GPU render performance is off. The average Geekbench 4 Render benchmark scores range between 4500-4700, mine are slightly below 4000.

The Antutu FPS appear to be far lower than the norm though.

Any suggestions?

[Galaxy Tab S2 Original Android Development] BARTVERSTRAETE:
So if I get it right its a driver issue in the kernel. Can't you get the driver code out of the original Samsung kernel and compile a new one?
[Galaxy Tab S2 Original Android Development] LuK1337:
Try it yourself.
[Galaxy Tab S2 Original Android Development] BARTVERSTRAETE:
Too bad I am not that hood, I know C but not that good.
[Galaxy Tab S2 Original Android Development] LuK1337:
That's just exactly like me, I avoid it as much as it's possible :^)
[Galaxy Tab S2 Original Android Development] Cyanogengod:
Hey there, do you have an idea regarding low gpu render performance in Geekbench and Antutu3D with your LOS release, compared to the stock Samsung Rom? (Scores in my previous post on page 9)

[MENTION=268073]top[/MENTION] post: I'm am currently working on a port of the Boeffla Kernel for hour LOS15 release. I have some questions though, that I will forward to the Lord.
[Galaxy Tab S2 Original Android Development] Cyanogengod:
Well, I think everbody would greatly appreciate it if you tried.

I gladly offer whatever help I can in return.

If I get the kernel working I'll instantly submit it, for instance.
[Galaxy Tab S2 Original Android Development] Kingvtt:
Hello, thank you very much for this rom! Finally lineage on t819, I waited for a long time.

I installed the latest version of 02/02 and immediately the gapps.

The Rom works but can not install apps from the playstore. The fingerprint sensor works but to return to the home screen impossible.

It's normal, there is still work, but really super happy that we are interested in this tablet.

See you soon.
[Galaxy Tab S2 Original Android Development] LuK1337:
I don't really care about any custom kernel.
[Galaxy Tab S2 Original Android Development] Cyanogengod:
Did you edit the installer.sh of the gapps zip as described in the second OP?

If you find the time, please post your Geekbench 4 and Antutu scores, it would really be a big help.
[Galaxy Tab S2 Original Android Development] emuandco:
Which gapps? https://builds.nezorfla.me/opengapps/arm64/ try these
[Galaxy Tab S2 Original Android Development] Cyanogengod:
Can you too please run Antutu3D and Geekbench 4 Compute to compare gpu scores?

I've tried on a second T819 with yesterday's release and it's the same thing.

In fact let's all compare notes on this, as it seems like an important issue if the GPU isn't properly utilized.
[Galaxy Tab S2 Original Android Development] emuandco:
I could not care less about some performance "problems" in 3D stuff. I need battery power and security patch levels as I use this device @ work. If I learned something in the past then that I never again will buy a portable device with muuuch power instead of battery. Anyways... here a Antutu 7.0.4 3D Beta Version score from my device: 104346 (48951 CPU, 17545 GPU, 31621 UX, 6229 MEM)

You know what, thats the cool stuff regarding FOSS. You can fix it yourself if you want.
[Galaxy Tab S2 Original Android Development] Cyanogengod:
Thanks a bunch for making the effort, I am reading tons of kernel documentation to be able to contribute to this thread as well. Boeffla Kernel will be truly awesome on this device.

I have attached my score, it's pretty much identical to yours.

We are about 25% below the stock t819.

The reason why GPU performance is important to me is because I watch 1080P video upscaled to 2048x1536 and 60FPS and it's lagging. If you could give me some hints I'll try to fix this myself and post my results.
[Galaxy Tab S2 Original Android Development] emuandco:
Hints? Try to check out what the stock firmware tells you the GPU can do and compare these with the LOS results. Stuff like OpenGLES, Vulkan, which versions of these, different OpenGL stuff being supported, clock frequencies. ALL STUFF. Maybe it's just a blob missing, maybe we just don't have the Samsung Benchmark cheating active :P
[Galaxy Tab S2 Original Android Development] RagingHarry:
I update every 2 to 3 days, but mostly I check github for changes, since not everyday there are important changes for our device.
[Galaxy Tab S2 Original Android Development] Cyanogengod:
Ok, I think I have an idea what's going on.

Did you extract the blobs from your device using adb or from a repo? If so, please post the link.
[Galaxy Tab S2 Original Android Development] RagingHarry:
For the ones interested "ViPER4Android FX Magisk v15 module" v6 by ShadySquirrel is working now out of the box and doesn't need the fix from the Viper4arise thread anymore (adding the so to /system/vendor/lib/soundfx/ file and manually adding the needed lines to /system/vendor/etc/audio_effects.xml)

For me the driver I/O install errors are gone now.
[Galaxy Tab S2 Original Android Development] emuandco:
Repo. https://www.dropbox.com/s/0fknl8w7zl6buz2/roomservice.xml?dl=0 But these blob's origin is a official RECENT firmware loaded from Samsung. What do you have in mind?
[Galaxy Tab S2 Original Android Development] LuK1337:
Soon on 02.08+ ~ https://browser.geekbench.com/v4/compute/1976254
[MENTION=8899746]Cyanogengod[/MENTION]
[Galaxy Tab S2 Original Android Development] RagingHarry:
That is quite impressive, getting 3750 on today's build, compared to your 5022.

With all the imported files from TheMuppets github is it advisable to rather clean flash or will a dirty flash be enough for now?
[Galaxy Tab S2 Original Android Development] LuK1337:
I didn't push anything to TheMuppets for 15.1 also it doesn't matter if you dirty flash or clean flash.
[Galaxy Tab S2 Original Android Development] RagingHarry:
Sorry my bad was a bit af a misreading on https://github.com/gts210vewifi-dev...mmit/753a785a76f8229153e915ef8ae7ee67ea664c30

At the top of the page, but that was it always..

forked from TheMuppets/proprietary_vendor_samsung

But never the less, those improvements are Hughes.
[Galaxy Tab S2 Original Android Development] Cyanogengod:
I suspected a blob issue.

I compiled my own version of LOS 15.1 with the help of your guide and I extracted the blobs from the t819 using adb. I got around 4200-4300 render score in Geekbench 4 which is what the stock t819 achieves also.

I've also done some work on the kernel port.

I am learning by doing, and using an old S3 as a dummy. If it gets bricked I don't care. Nothing flashable yet, but I am getting closer to fully understanding how the Boeffla Kernel is set up.

The initial port shouldn't be that hard.

With you guy's latest 2018-02-09 release I get a Geekbench 4 Render score of 5100, which is quite an improvement.

Since I spent days and infinite nerves compiling this ****ing thing until it finally flashed correctly, I would like to explicitly know what was modified to increase rendering so dramatically, as I obviously didn't fully figure it out.
[Galaxy Tab S2 Original Android Development] LuK1337:
I replaced whole adreno stack with 8.0 stack extracted from Sony Xperia X Compact.

Oh BTW your build with fresh extracted blobs would likely have a broken camera preview :^)
[Galaxy Tab S2 Original Android Development] Cyanogengod:
Because of the same adreno 510 source and drivers, but way more up to date? That's actually ingenious. If you check the Geekbench 4 Render database on the t819, not a single device has even come close to that score. https://browser.geekbench.com/v4/compute/search?utf8=✓&q=T819

Really impressive, you should be pushing this from a dedicated website, earning some ad revenue.

Lol I just checked because you mentioned it and I get a black screen on my build after opening the camera app. When I press the trigger, pictures/videos are taken and look fine, but it doesn't show anything while taking it.

Just for fun I'll try to do the same with the adreno stack.
[Galaxy Tab S2 Original Android Development] LuK1337:
Well I didn't expect that you'd be getting black screen, I expected that you'd see a corrupted preview with green lines and what not.
[Galaxy Tab S2 Original Android Development] Cyanogengod:
I already fixed it. No it was a black screen, and would show thin blue lines, not green.

All I had to do was change the color gambit parameters for screen calibration and camera. This is apparently a common problem when using freshly exported blobs on some tablets.

I had the same when playing video or scrolling pages. There I had green, blue and yellow lines and interference.
[Galaxy Tab S2 Original Android Development] LuK1337:
Sounds like you did something wrong cause I fixed that with a stupid sed lol. Also funfact: only 4:3 resolution has broken preview.
