Did you install the correct twrp with the vendor partition visable ?

All worked fine with me the first try comming from stock oreo.
[Galaxy Tab S2 Original Android Development] DutchDanny:
A lot of you might go wrong because 15.1 supports treble

Treble is new from Google to make it easy for Samsung and others to update their hardware.

With this they create a new partition on your phone called: vendor

Use the recovery for T810 in THIS POST

Use the ROM posted by bonuzzz HERE

Before on Oreo we all installed on the system partition, but now its cut in 2.

system & vendor

If you do not prepare your device properly the vendor partition is not written, and you'll end up not booting.

Backup your whole device to the cloud or pc.

Flash the recovery from above post.

In recovery go to ->wipe ->advance wipe

select top 6, leave bottom 2 untouched.

reboot again to recovery go to -> wipe

wipe data here, and reboot recovery again.

Now copy your LOS and GAPPs files and flash them

If no boot, flash only LOS again, wipe dalvik/art and reboot

Down here you see what you need to have in recovery advance wipe menu:

[Galaxy Tab S2 Original Android Development] frankieboy1233:
Situation is the same, on the T810 after the install, the android logo appears and grey out, won't boot. By the way, the T810 doesn’t have official oreo, it was issued with android 5.0.2 in 2015, and currently has 7.0, and official oreo has less probability because Samsung supports only two major version update. 7.22 version works with the known bugs.
[Galaxy Tab S2 Original Android Development] dombo1970:
I might be wrong but I already installed the 20180722-version of LOS, and it worked! Why should this be the reason for not being able to install the latest LOS?

And as frankieboy1233 wrote Samsung isn't supporting Oreon on this device.
[Galaxy Tab S2 Original Android Development] mtnez.david:
The last builds from [MENTION=242033]bonuzzz[/MENTION] are treble enabled, that's why you need a specific recovery. With treble you can have one independent partition for vendor folder, that's right, however it's not the case in this device. Here there is only one partition, however the /vendor folder is independent from the system (the idea is to flash the system while keeping that folder). Therefore what the new recovery will do is mounting that folder separately. Once you have it you could go to wipe in twrp and the vendor folder will be there.

Before flashing this ROM for the first time you do wipe of everything (except storage if you want), format first if necessary.

I see that many people are having troubles flashing this. Maybe it's device related. In T710 it went very smooth.

I hope I help someone.

[Galaxy Tab S2 Original Android Development] frankieboy1233:
I think more test builds needed to find the error on T810, because it installed to the vendor partitition, as I saw the twrp message.
[Galaxy Tab S2 Original Android Development] moonboy2:
I´m back now with my T815 to stock cause LOS is to complicated to install.

Stock is running fine so far.

Maybe i´m going to sell my T815 soon and changing to a new tablet.
[Galaxy Tab S2 Original Android Development] triniboy:
T810 Install

I can confirm that you have to install the rom and gapps reboot to recovery and reinstall rom only and boot normaly. Obviously follow in detail the new instruction steps provided. I guess if you are already on oreo there is no issue. I did get a boot issue attempting to install magisk... and had to repeat the installation process to clear ... so how do we root this bad boy?
[Galaxy Tab S2 Original Android Development] dombo1970:
I did it somehow. Installed TWRP into vendors, wiped everything, flashed LOS and GApps, booting, no problem.

But after reboot same issue as before, hanging before booting.

Restored my backup, am back on the 20180722-version again. :(:(:(

My question is: Isn't Treble useless for this device when we always use TWRP for flashing updates?
[Galaxy Tab S2 Original Android Development] triniboy:
Sounds like you did not reboot into recovery and reinstall the rom only. When you have installed both rom and gapps reboot to recovery from twrp
[Galaxy Tab S2 Original Android Development] dombo1970:
So I should flash LOS and GApps, reboot into recovery without booting to system, then flashing LOS again?
[Galaxy Tab S2 Original Android Development] triniboy:
Yes worked for me on a t810:D
[Galaxy Tab S2 Original Android Development] dombo1970:
Okay, finally I got it.

Wiped all but vendor

Restarted into Recovery

Installed LOS and GApps

Restarted into Recovery

Installed LOS

Booting

...

...working. :)

I really really really hope that next time this procedure is not necessary again.
[Galaxy Tab S2 Original Android Development] frankieboy1233:
Thanks for the tip, that worked for me on T810, earlier, I tried to install magisk, that's why it stopped on the android logo.
[Galaxy Tab S2 Original Android Development] dombo1970:
I tried to flash Magisk, now it stopped again on the logo.

Reflashed LOS, not helping.

Reflashed again, still not helping.

So without Root its working, with Root its not.

Only trouble with Treble. Treble-Trouble²!
[Galaxy Tab S2 Original Android Development] khaberz:
Wireguard?

Are there any plans to add wireguard support to this ROM per https://xdaforums.com/android/development/wireguard-rom-integration-t3711635 ?
[Galaxy Tab S2 Original Android Development] citydweller1985:
Any plans on Android Pie?
[Galaxy Tab S2 Original Android Development] Inkypen:
I successfully flashed 0811 version on my T815, as some commenters have mentioned you do need to reboot into recovery several times. I find it odd no one has got Magisk to work, what versions are people using? Magisk has supported treble since version 16.6, and the latest 16.7 version installed for me with no issues!

---------- Post added at 11:16 AM ---------- Previous post was at 11:14 AM ----------

Forgot to mention, the rom is pre rooted with the official lineage su addon, so I used the official su removal before flashing Magisk.
[Galaxy Tab S2 Original Android Development] shpitz461:
Can you list what's working and what's not? mic? video? gps?
[Galaxy Tab S2 Original Android Development] Inkypen:
GPS and fingerprint scanner works fine. Microphone and mobile data worked in previous build, doesn't in this one. Video recording doesn't work, never tried it in previous build.
[Galaxy Tab S2 Original Android Development] Meakii:
How's your standby idle battery drain? For me on T815 all recent builds drop like 15% overnight on airplane mode with and without Gapps installed. Only thing holding me back from updating.
[Galaxy Tab S2 Original Android Development] moonboy2:
[MENTION=5538801]Meakii[/MENTION]

I had the same battery drain over night with LOS and RROS on my T815.

So I returned to Samsung stock firmware.

Actual version is

Security Patch Level 2018-06-01

Product code DBT

PDA T815XXU2CRH1

CSC T815OXA2CRH1

Now 0% battery drain.
[Galaxy Tab S2 Original Android Development] Meakii:
I'm currently still on LOS build from 11 May and the battery life is amazing. Standby drain is about <1% over 8 hours :good:
[Galaxy Tab S2 Original Android Development] dombo1970:
Same here on the T810 with latest LOS (20180812): 10 hours standby <1%.

Mic and video recording not working, but I'm not missing it.
[Galaxy Tab S2 Original Android Development] Inkypen:
Did a test, charged battery to 100% and left overnight. Battery was at 80% after 15 hours of standby. I thought that was ok, but other people are getting a drain of around 1% for roughly the same time! I guess a major factor in this is the age of the battery and how many charge cycles it has been through. I might go back to stock ROM and test again to see the difference on my own tablet.
[Galaxy Tab S2 Original Android Development] paul c:
I flashed the 22nd August version on my t810 (WiFi only model), including wipe AND format of data partition, and format of SD card, and restore of 80 user apps via TiBu. After a couple of days to let it settle down, I charged it up, and after 23 hours and 8 minutes since full charge and on standby, it still shows 100% battery.

11 minutes screen on time, and a Titanium Backup ran on a schedule to backup 80 user apps. I use LeanDroid to connect once an hour.

I don't use the tablet intensively, so battery health is probably very good.

All the same, I'd say this demonstrates there are no issues with the ROM itself - at least for the WiFi variant.
[Galaxy Tab S2 Original Android Development] Inkypen:
Thinking about what you said made something click in my head. I have the T815 model and even though this build doesn't even recognise the inserted SIM card (says no SIM inserted) 16% of my battery drain was due to mobile network standby. :confused:

It seems like people complaining of poor battery life have the T815 and people who have great battery life have the T810
[Galaxy Tab S2 Original Android Development] Meakii:
Did you try on airplane mode? I don't use mobile network on mine and always have it on airplane mode but still have mad idle drain T815. Yet don't on stock or 11 May build.
[Galaxy Tab S2 Original Android Development] Inkypen:
I've reflashed my tablet back to Nougat to check idle battery drain. I don't feel like messing with Odin so have flashed official Lineage 14.1, will compare to unofficial 11 august version, then to unofficial 22 July version.
[Galaxy Tab S2 Original Android Development] Inkypen:
Official Lineage 14.1 was even worse, 70% battery after 15 hours. 24% of battery was due to mobile standby. I will go back to 11 august version and check again
[Galaxy Tab S2 Original Android Development] Adler12:
Update?

Hello, is there any hope that there will be another 15.1 update for the T815, S2 9.7 LTE? For me, the image runs great
[Galaxy Tab S2 Original Android Development] moonboy2:
[MENTION=1044183]Adler12[/MENTION]

I suppose there will come no official version of LOS 15.1 for T815.

My solution was to reinstall the last version

DBT Android 7.0

PDA: T815XXU2CRA3

CSC: T815OXA2CRA3
[Galaxy Tab S2 Original Android Development] Meakii:
How'd they work out for you? Interested to know if either were any better?
[Galaxy Tab S2 Original Android Development] Inkypen:
Battery drain on stock was identical to Los 14.1, 70% charge after 15 hours, although the stock ROM showed only 1% drain due to mobile standby. My method here is to flash relevant ROM, charge to 100% and then leave tablet idle. No airplane mode but no screen on time either. I personally only use the tablet lightly, however I purchased it secondhand so have no idea about previous usage/charge patterns.
[Galaxy Tab S2 Original Android Development] subirghosh:
Yes

Yes, I just flashed.

[Galaxy Tab S2 Original Android Development] dombo1970:
Btw video recording is also not working.
[Galaxy Tab S2 Original Android Development] dombo1970:
Was someone able to root this Rom on the T810 successfully?

Am having a 18gB (!)-File somewhere in images causing the main partition to run out of space, and i can't find anything, maybe root can help.

Or is Treble causing this maybe? Wasn't checking the availabe space before getting this "out of memory"-warning.
[Galaxy Tab S2 Original Android Development] halloarno:
Magisk roots the 810 just fine.
[Galaxy Tab S2 Original Android Development] dombo1970:
My last attempt (see several posts ago) freezed my tablet completely.

How were you flashing magisk, together with LOS and GApps, or separatly?
[Galaxy Tab S2 Original Android Development] halloarno:
First Rom+ (open)gapps > boot device > magisk 17.1
[Galaxy Tab S2 Original Android Development] dombo1970:
Was working. Am wondering why I was failing before.

Nevertheless I found the big file, even without root, in the trash can of ES file manager...:silly:

[Galaxy Tab S2 Original Android Development] Jos.e67:
Just checked and the microphone doesn't work. You're right. But it's not something important for me in the tablet. The camera works fine... Anything else you might want to hear about?
[Galaxy Tab S2 Original Android Development] shpitz461:
Thanks for the confirmation. It's my son's tablet and he uses the mic with voice changing apps, so that's a must. That's why I'm on stock rom for now...
[Galaxy Tab S2 Original Android Development] reiiiii:
For me, I'm on an SM-T815Y. It works along with the microphone but it's pretty quiet.
[Galaxy Tab S2 Original Android Development] Kocane:
So all in all, there's not really any reason to use 14.1 over 15.1 on a T815, is there?
[Galaxy Tab S2 Original Android Development] moonboy2:

[Galaxy Tab S2 Original Android Development] dannychow:
Hi all, I have a copy of bonuzzz 's git for T815 and I tried to build the newest LOS 15.1 based on some files in it.

I have no time yet to test it on my device. You can try it if you have interest:

https://drive.google.com/open?id=15fsfLn1AJ7E4enkBcSDMmstIjG94i0J0

(lineage-15.1-20181117-UNOFFICIAL-gts210ltexx.zip)

EDIT: I mainly uses the device files from LOS15.1 's source tree. Only a couples of files from bonuzzz device tree are used for successful build.
[Galaxy Tab S2 Original Android Development] ripee:
I'll take a look at your device tree. Do you also have the blobs?
[Galaxy Tab S2 Original Android Development] dannychow:
blobs for T815, it is extracted from the previous LOS15.1 build of bonuzzz:

https://drive.google.com/open?id=1wCS94hFWQjXm-XuIZNd4eTT3MUb2d2em

T815 device source backup of bonuzzz:

https://drive.google.com/open?id=1lTWV0uuND_IwUZkPf_KwLn3g0k1ebxU_
[Galaxy Tab S2 Original Android Development] ripee:
Thanks! With these I will hopefully also be able to re-create the sources for gts28ltexx (unless you have those as well). I myself had forked the gts210wifi sources, and had extrapolated the gts28wifi sources from those, including the blobs from the latest stock system image.
[Galaxy Tab S2 Original Android Development] dannychow:
I basically, tried to build the LOS 15.1 with the original LOS device source for gts28ltexx with a couples of files from bonuzzz 's device tree.

Or should I completely use bonuzzz device tree instead of LOS 's one? Which approach is better or more stable?
[Galaxy Tab S2 Original Android Development] ripee:
bonuzzz's repos are definitely more stable. T_I has forked the official repos into his github.com/galaxy-tab-s2 account, but hasn't yet continued working on them. We should ask him if we can contribute to that organizational account.

Also be sure to apply bonuzzz's patches from gts2-common/patches.
[Galaxy Tab S2 Original Android Development] dannychow:
I don't have the bonuzzz patches (gts2-common/patches). Can you send to me?

If you have gts210wifi device source from bonuzzz, please also send to me as a backup. Thanks!
[Galaxy Tab S2 Original Android Development] ripee:
See my github. I imported the gts210ltexx device tree as well as the blobs.

Just some feedback

..just flashed ripee 's version 15.1 20181128

and it works just fine - thanks [MENTION=6005084]ripee[/MENTION]

Only issues i found so far

* mic not working (or at least not good, quite still and sounds broken) - but that's for some time now (see above)

* audio output - is sometimes a bit unclean (will test different sources files and video players)

So if those do not bother you - ripees build could be the choice for you.

For me as tv junkie the audio glitches might force me back to last stable and official 14.1

Cheers
[Galaxy Tab S2 Original Android Development] ripee:
Thank you! The audio is certainly something to look at, but my priority now is to fix the modem on both LTE variants. I'll look at the audio later, or if someone has any suggestions, I'm all ears!

[MENTION=6012697]halloarno[/MENTION], if you use magisk modules to improve the mic and speakers, then I'm sorry but your feedback won't help me.
[Galaxy Tab S2 Original Android Development] halloarno:
If I reported an issue, indeed. Neverless I disabled the modules. And audio seems alright.
[Galaxy Tab S2 Original Android Development] CuckooPenguin:
Well did not think or even expect your would jump to the rescue for audio .. ;) Modem is far more important for sure.

I tested few files and players and maybe i was just imagining those *cracks* ..

The mic works - but input level seems to be pretty low.

I wonder is there a better tool to test and get a more objective result - like a tone-generator feeding back in its own mic to compare ?

Aside from that stable and snappy - battery looks good as well

still testing.

Thanks!

This is the latest custiom ROM for T815? / Is it possible to flash it via ODIN?

Hello.

This is the latest custom ROM for T815?

Is it possible to flash it via ODIN?

I had used TWRP, but now it does not boot (endless). And I can not shut off. I have to wait for a empty battery.

And the open gapps installation says it can not install gapps, because it has not 8.1 (only stock 7.01). But that is wrong. At the endless "booting" process, there is this blue line with die circle from right to left.

This is (this) Lineage 15.1, i think "Android 8.1". And i had choosed the 8.1 gapps (ARM 64bit)...

I would try it with ODIN, perhaps this is better.

But I need a file, or files for flashing. For "AP" (etc..?).

P.S.: With stock, there was only ~20Mbit WLAN (5Ghz). Note 4 with stock and (2 different devices) LineAge 15.1, no problem, full speed.
