I have been on a really old firmware version but LOS16 is running fine for me. Do I need to flash any new firmware? It looks like there have been new firmwares from samsung late last year. I think latest is T813XXS2BRI1.
[Galaxy Tab S2 Original Android Development] eggmek:
Hey There Guys,

im on a T815. So i Tryed to get to everything done. Downloaded all the things i need. Image from Sourcefroge for LTE. Installed TWRP 3.0.0.0 think that was wrong after that downloaded twrp 3.2.3.0/1 installed it.

Then wiped Tablet. But i cant get the Wifi or the LTE image to install.

Im always Getting Error 255 i googled but i dont rly know what im done wrong so far.

As this thread contains no help or TWRP data so i downloaded from official site.

Maybe you know what im Doing wrong. Dont want to be stuck on 7.0 :D

I don't support exynos devices.
[Galaxy Tab S2 Original Android Development] eggmek:
Oh now i get it 813 Is on Qualcomm Chip ;(. Hm didnt read that. Im sorry thats too bad for me ;/
[Galaxy Tab S2 Original Android Development] Meakii:
Out of curiosity how is idle drain on this? Does it manage to make deep sleep ok?

Thanks in advance

Been a while since I've tried LOS 16 on any of my devices. Very glad to see privacy guard has finally been implemented. To me that's the most important feature of LOS.

I immediately made my tablet very angry by just trying to setenforce to 1 , without thinking... This does not work. This feels pretty solid at this point though, is there really a reason the kernel is still set to permissive? Or will it be this way until LOS 16 goes official?
[Galaxy Tab S2 Original Android Development] LuK1337:
>This feels pretty solid at this point though, is there really a reason the kernel is still set to permissive?

Me being lazy.
[Galaxy Tab S2 Original Android Development] OhioYJ:
Not like you aren't busy enough doing a lot for the community. I have 3 T813s in my house all running Lineage, thanks to your hardwork.
[Galaxy Tab S2 Original Android Development] Lupin The Third:
I keep going back and forth from LOS (thanks to [MENTION=5075128]LuK1337[/MENTION]) to stock rom.

The battery life is the drawback for me. On stock I get ~7, 8 ours of SOT but with LOS and same usage, ~4, even with battery save mode on.

I didn't try the 2 latest builds though. I hope things are improved in that department. :)
[Galaxy Tab S2 Original Android Development] SteenC:
I have installed LOS 15.1 on my Tab S2 gts210vewifixx, and I'm trying to install LOS 16, but it dosn't work. I suspect, that it has something to do with the bootloader, I have a T813XXS2BRI1 bootloader.

Can I add my bootloader-number to metadata, updater-script and bulid.prop files, and then it will work?
[Galaxy Tab S2 Original Android Development] LuK1337:
Unless you're flashing like really old build we should no longer be checking bootloader version, instead we are checking TZ version.
[Galaxy Tab S2 Original Android Development] SteenC:
You're absolutely right. I picked the first build on the webpage, but thats the oldest build. I'll try with the newest build

Thanks a lot:)
[Galaxy Tab S2 Original Android Development] OhioYJ:
Camera working for anyone in the latest build? I've tried on two different tablets and it immediately crashes. Open Camera says the camera is already in use and just displays a blank screen?
[Galaxy Tab S2 Original Android Development] SteenC:
Camera works almost. It don't crash, but if I take a picture it keeps taking pictures until I close the camera-app
[Galaxy Tab S2 Original Android Development] OhioYJ:
Hmmm, I wonder what I did wrong then. I just get a black screen and immediate crash. I did a dirty flash, I guess I'll try a clean flash first.
[Galaxy Tab S2 Original Android Development] IronW:
My camera is working fine on the latest build.
[Galaxy Tab S2 Original Android Development] Dastonie:
Camera works fine with 12.01.19 build. Front and back, both working...
[Galaxy Tab S2 Original Android Development] OhioYJ:
Ok so here is a million dollar question, what camera app is everyone using? I tried to do a clean install... I wiped everything, including system. Installed the 12 Jan build, there is no camera app. Open Camera still has the same error I mentioned above. So now I'm more confused.
[Galaxy Tab S2 Original Android Development] Meakii:
How is your idle drain? Main question... does this make deep sleep at all?
[Galaxy Tab S2 Original Android Development] Lupin The Third:
It doesn't look like to me.
[Galaxy Tab S2 Original Android Development] Dastonie:
Already installed yesterdays build from 16th, but following my version:

com.android.camera2

Version 2.0.002
[Galaxy Tab S2 Original Android Development] meditate2001:
awesome rom ! thanks a lot LuK1337 !!!

it is way snappier than the v8 costum roms. i really liked the ressurection remix, but if i have to choose between 8 and 9, i prefer 9....

cam - app: on board:

com.android.camera2

Version 2.0.002

everything works great so far !

Hello,I want to return to stock rom,but impossible to flash with Odin.Any solution please?
[Galaxy Tab S2 Original Android Development] IronW:
Anyone else getting high battery background usage by Android Keyboard (AOSP) on the latest build?
[Galaxy Tab S2 Original Android Development] ericcl:
I used GSAM to try to figure out what was causing my high battery drain, but it was never one particular app or service (other than Google Play Services, that is). I would get high values for display, even though the screen was off the entire time. I'd go from charged to 80% in 1 afternoon with no usage or screen-on time.

Look at this post in the 15.1 thread. The author uses an Automate pattern to shut off wi-fi when the screen is off. This seemed to fix the problem for them and it has for me as well.

Error in flashing

This is likely because my tablet is in some particular mode, not because this ROM isn't working.

I got this tablet from Costco and it was in the retail mode (i.e. apps can be installed but the device will be reset to the original state regularly). I failed to install the Android 6 & 7 images from updato via Odin (it stopped near the end of the process).

I flashed TWRP 3. via Odin, copied this ROM zip file to `/sdcard/`, installed it and these are the errors:

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

Failed to mount '/data' (Invalid argument)

Unable to recreate /data/media folder.

Updating partition details ...

Failed to mount '/system' (Invalid argument)

Failed to mount '/data' (Invalid argument)

...done

Unable to mount storage

Failed to mount '/data' (Invalid argument)

...

assert failed: samsung.verify_trustzone("TZ.BF.3.0.3-00054", ...) == "1"

Does anybody know how to fix these issues?
[Galaxy Tab S2 Original Android Development] Lupin The Third:
Coming from stock rom, you have to format data on twrp to remove stock encryption. Not just wipe, but format, by typing yes when prompted.

Note: This will delete all your data and internal storage.
[Galaxy Tab S2 Original Android Development] dxxvi:
This is what I just did twice: Wipe | Format Data | Type yes and click the Tick key, then the screen showed:

Updating partition details...

Failed to mount '/system' (Invalid argument)

...done

Full SELinux support is present.

...

assert failed: samsung.verify_trustzone("...", ...) == "1"

Updater process ended with ERROR: 7

Error installing zip flle '/sdard/lineage-...zip'

Updating partition details...

Failed to mount '/system' (Invalid argument)

...done

Did I miss anything?
[Galaxy Tab S2 Original Android Development] Lupin The Third:
Which twrp version are you using?

Use latest from here:

https://dl.twrp.me/gts210vewifi/
[Galaxy Tab S2 Original Android Development] dxxvi:
That's what I'm using (twrp-3.2.3-0-gts210vewifi.img.tar).
[Galaxy Tab S2 Original Android Development] Lupin The Third:
Would you mind attaching here a screenshot of the error in twrp?
[Galaxy Tab S2 Original Android Development] dxxvi:
I can see myself in the pictures below :)

p1.jpg: type yes, then click Tick to format the partitions

p2.jpg: format completed

p3.jpg: choose the zip file to install

IMG_20190120_140323.jpg: installation error message

I think the partion to mount /system to doesn't exist (that might be resulted from the failed flashing of Samsung image via Odin).
[Galaxy Tab S2 Original Android Development] Lupin The Third:
My two other suggestions:

Reflash latest stock firmware and repeat process

Make sure your download file is not corrupted.
[Galaxy Tab S2 Original Android Development] dxxvi:
I already downloaded different stock firmware.They are all unzippable and pass the check by Odin. So I guess they are ok.
[Galaxy Tab S2 Original Android Development] Lupin The Third:
Not sure what you mean... The firmware files should be unzipped though. The file has to be with a .tar.md5 extension for odin use.

And a ps: you did unlock the bootloader right? :)
[Galaxy Tab S2 Original Android Development] NordOstSee:
Same at my side for the high battery drain.

What I saw is that the Deep Sleep Mode is never activated (checked with CPU Spy).

The below solution is working for me (readed in a different discussion):

Toggling of the Flight / Airplane Mode.

I did it in this way:

1.	Activating of Airplane Mode

2.	Restarting of tablet

3.	Deactivating of Airplane Mode

4.	To check the Deep Sleep Mode: Resetting of CPU Spy log

5.	Wait few minutes to check if Deep Sleep Mode is working
[Galaxy Tab S2 Original Android Development] Lupin The Third:
This ^

Seems to work in los 15.1 too.

Tagging [MENTION=5075128]LuK1337[/MENTION] maybe you would appreciate to know? Perhaps helpful to investigate? Maybe you already knew this, but just in case. Sorry to bother you! :)

I always went back and forth from stock to los because of bad battery life. And this seems a nice workaround atm.
[Galaxy Tab S2 Original Android Development] OhioYJ:
Well, I updated two of my three T813s with the latest build (16 Jan) and the Camera issues are fixed. I did a clean flash on one, dirty flash on the other (both coming from LOS 15). No issues on either.
[Galaxy Tab S2 Original Android Development] BakaNeko59:
Recent Apps

I just did a full wipe and install of this with opengapps and Magisk. When I hit the "recent apps" button it says that are no recent items. Any ideas?

I'll try wiping and reloading again to check it out.

EDIT: I did an "upgrade install" over the top of my first install and the problem is gone…
[Galaxy Tab S2 Original Android Development] OhioYJ:
The latest build the kernel is no longer permissive! Kind of looking like this is definitely ready to go official whenever Lineage finally takes 16 official. Everything is still running solid.

As for battery life / deep sleep issue, I've been using NapTime By Francisco Franco. My wife's tablet last night had 4 hours of SOT with the last charge being 6 days ago, still at 42%, my tablet has still been managing 6-7 hours of SOT. I kill everything when the screen is off, Wifi / location, etc, but it's made a big difference from before. Even my son's tablet is going over a week (sometimes he forgets about it) without needing to be charged.
[Galaxy Tab S2 Original Android Development] motion_blur:
I also get functioning deep sleep with lineage-16.0-20190206
[Galaxy Tab S2 Original Android Development] jchen12:
I hate to ask here but [MENTION=5075128]LuK1337[/MENTION] is it possible to download your last build of 14.1 ( lineage-14.1-20180220-nightly-gts210vewifi-signed.zip)? I need to run 7.0 because Oreo always kills the background process of an app i need. The mirrors on the lineageos site are all dead. Thanks for your help.
[Galaxy Tab S2 Original Android Development] jchen12:
Thanks
[Galaxy Tab S2 Original Android Development] Dastonie:
Yes it's possible to download. Just wanted to answer the question correctly.

I checked it out and there is a tool called Google to get help. ;)
[Galaxy Tab S2 Original Android Development] jchen12:
Thanks, I found the build on archive. Since the checksums match the ones on the lineageoslog, I guess its legit.
[Galaxy Tab S2 Original Android Development] Dastonie:
Guys, do not forget to donate to the great work of LuK. (See his signature)

I just donated (again) to his great work (I am not in any relationship to him, I simply respect his great efforts)
[Galaxy Tab S2 Original Android Development] IronW:
I flashed the latest build a couple weeks ago and it runs great. I've only found two issues.

The backlit buttons aren't working and cast isn't working.

Anybody else having these issues?
[Galaxy Tab S2 Original Android Development] LuK1337:
You sure that's the latest build? lol

Button backlight was fixed months ago, tho Miracast won't be working anytime soon as Google killed it.
[Galaxy Tab S2 Original Android Development] IronW:
Yup, it's the latest build from 0206. I checked my second tablet with the same build on it and the button backlights are working fine there. A quick reboot and they work again, lol I feel dumb.

That sucks Google killed cast, that was handy.
[Galaxy Tab S2 Original Android Development] darzur:
Hi,

Is it safe to upgrade to this ROM from LOS 15.1 official without wiping data? TBH I don't have any pressure but it will be nice to have. [emoji3]

P. S. Does it have OTA updates?
[Galaxy Tab S2 Original Android Development] LuK1337:
No to both.
[Galaxy Tab S2 Original Android Development] darzur:
Thanks. Forgot that Xposed is not available for Pie so will not upgrade anyway.

Backlight of buttons is Not working for me either since February build. Reboot does not work for me though.
[Galaxy Tab S2 Original Android Development] LuK1337:
If you want to be helpful join my IRC channel (see my signature) otherwise forget about backlight ^.^
[Galaxy Tab S2 Original Android Development] moddex:
Thanks for the offer. I could actually solve the problem myself, I reflashed the build and current gapps, now it's working again. :)
[Galaxy Tab S2 Original Android Development] cucumbersmell:
It's official! Thank you!
[Galaxy Tab S2 Original Android Development] fehrcomp:
Official - oh what a great surprise!

Is it possible to dirty flash or is a factory reset mandatory?

Thanks anyway for all your work here!
[Galaxy Tab S2 Original Android Development] LuK1337:
Official -> Official => Follow instructions in the blog

Unofficial -> Official => Wipe data and start over
[Galaxy Tab S2 Original Android Development] kdrkdr:
This means Factory reset and wipe data?
[Galaxy Tab S2 Original Android Development] LuK1337:
...obviously?
[Galaxy Tab S2 Original Android Development] optionalmgrr.la:
It works be nice if we can 15.1 to 16 but still thanks a lot :)
[Galaxy Tab S2 Original Android Development] Malstrond:
Since this hasn't been mentioned yet, I just wanted to report that dirty flashing official images (from lineage-15.1-20190224-nightly-gts210vewifi-signed.zip to lineage-16.0-20190302-nightly-gts210vewifi-signed.zip) worked with encryption being enabled.

Flashed the OS image, MindTheGapps and your su in one go, cleared cache, rebooted.

The only issue I noticed is that the launcher lost its settings.
[Galaxy Tab S2 Original Android Development] OhioYJ:
So far I've noticed no issues from dirty flashing unofficial the last build LOS 16 to official LOS 16. I've only done this to one of the four tablets in my house so far though. Going to use mine for a few days and make sure no issues crop up before doing the rest.

Figured the worst thing that happened was I would have to actually wipe it and do it right with a fresh install.
[Galaxy Tab S2 Original Android Development] moloko01:
Thanks for bringing our device to Pie.

But button backlight don't works stable. Sometimes I have to reboot.

Please fix it.

[Galaxy Tab S2 Original Android Development] OhioYJ:
Have you tried a clean install? So far my button backlights have worked fine.
[Galaxy Tab S2 Original Android Development] moloko01:
Yes, clean Installation with gapps and magisk.

Button backlight is instabil.
[Galaxy Tab S2 Original Android Development] BamaInArk:
I just got my Tab S2 updated last night from 15.1 to 16.0. Actually had to do it twice but not due to an error. Anyway one issue I am seeing is on one specific App...."Wifi Analyzer" by farproc. V3.11.2. The App runs however it doesn't seem to be able to detect any wifi signals....either 2.4 or 5 range. It was working before using Lineage 15.1. I have uninstalled and reinstalled, twice. Now there are 2 versions. Seems a newer version shows "This app may not be compatible" Then there's the Classic version 3.11.14. Neither seems to be able to pick up a wifi signal. Depending on which screen view is selected sometimes it asks to select an AP but then shows no wifi in range. Although the tablet is connected to my wifi network and is working fine.

I'm not sure if I'm missing some setting somewhere but never had this issue with other devices.
[Galaxy Tab S2 Original Android Development] steffxyz:
Did anyone tried to cast the screen to TV/Beamer with the new official LOS16 on SM-T813? I did this hundred times with LOS15.1 on my SM-T813, with LOS15.1 no problems at all. But with LOS16 the Tablet starts connecting and then it reboots, no matter wether clean install or dirty flash from LOS15.1... The ROM is real great, but there seems to be a little bug - or is the user buggy???

Thanks for help
[Galaxy Tab S2 Original Android Development] steffxyz:
I had a similar problem with VREM WiFi Analyzer on LOS16, the problem is probably by changes on Android 9:

look github.com/VREMSoftwareDevelopment/WiFiAnalyzer/wiki/Location-Service-Permission-Requirements

The new version of VREM WiFi Analyzer (2.0.3) asks for permissions and works fine - maybe there is the same problem with Wifi Analyzer by farproc, you may try VREM WiFi Analyzer.
[Galaxy Tab S2 Original Android Development] itsamess:
Sorry, but i am an idiot:

How do i get Google Assistant to work?

I installed the App, but nothing happens.
[Galaxy Tab S2 Original Android Development] KritonK:
I had the same problem with WiFi Analyzer, which I had restored using Titanium Backup. However, uninstalling and reinstalling fixed the problem for me. Assuming that this was a permission problem, with the app having stored somewhere that it had already obtained the required permissions, turning them on by hand might also have worked.

As to why this didn't work for you, did you dirty flash, by any chance? Mine was a clean installation.
[Galaxy Tab S2 Original Android Development] itsamess:
Thx for the help. I did a full wipe, even formatted. Reinstalled the app, restartet, checked options. Nothing happens when i long press the home button.

Edit: on my second t813 i did the normal process from official --> official, but Google assistant isn't working either.

Interesting: when I open the assistant app on the second device, the assistant starts. When I open the assistant app on my first device (the one with full wipe), Google discover opens.

Edit 2: with 15.1 it worked on both.
[Galaxy Tab S2 Original Android Development] fehrcomp:
Here no problem. I start the assistant thru Nova launcher. Works like a charm.

Google App info:
[Galaxy Tab S2 Original Android Development] fehrcomp:
Stream to chromecast works here. Direct screen mirroring and over TV-Apps.
[Galaxy Tab S2 Original Android Development] BamaInArk:
In my case I am resinstalling a 4th time. The last time I did the memory thing that combined the internal and ext memory. Not sure what I gained by that. I am flashing from Recovery so nothing "dirty" in my case. Plus I was seeing a few App updates via Market that were unable to install. Not sure what was causing that. Thus the reinstall.

Also for a question about wireless connections speeds. With my stock firmware I was able to see 250 Mbps plus download speeds using my 5G wireless connection. Obviously closer to my AP. At this point I do not remember what I was seeing using LOS 15.1 but with LOS 16.0 I am seeing no more than around 150 megs down. Not critical but was just wondering.
[Galaxy Tab S2 Original Android Development] itsamess:
Ok, as I said: I'm an idiot.

The assistant wasn't set in the system option "standard-apps". Now it's working.

I thought it would do this on it own.
[Galaxy Tab S2 Original Android Development] musashiken:
So I think my tablet is dead. I was on unofficial build 04 Feb and it was working fine until I decided to clean flash the official latest build yesterday.

Now my tablet keeps bootlooping. Not sure what's wrong, I always do the same thing, full wiped, flashed rom, gapps and su.

Tablet will boot but right after it boots, it will just restart.

I have tried clean flashing to my previous unofficial build which I know works, but now it just bootloops everytime it goes into android.

Sometimes it even reboots while I'm flashing the rom inside TWRP!

One time, it just stays at the Android splash screen until I had to hard reset the tablet and bootloop will just occur.

I can still go into recovery if I'm quick enough to press the buttons together. And most of the times I can still flash the zips. I always keep a copy of the older rom, gapps and su that I used previously but even clean flashing those will just result in forced restart every time I go into LineageOS.

The first 2 times, I could still go into android and enter my google account details, but once it turns on wifi to do so, reboot happens.

The next time I clean wiped, I can't even wait for that and the tablet just reboots one second after it boots into LineageOS.

So I guess there could be something physically wrong with my tablet. RIP...
[Galaxy Tab S2 Original Android Development] moloko01:
Hi, I whipped everything and did a clean install of official LOS16 nightly, nano-gapps and Magisk. I managed everything and start over with Titanium. So far so good.

When I reboot my Tab stops at Home screen, no WiFi, no SD available. It shows a massage 'Der Prozess System kann nicht gestartet werden'. Then screen goes black. After a while it shows "Tablett wird gestartet...". After a while it ends in TWRP homescreen. I have to clean Dalvic cache and cache and reboot every time to got Tablet then working. This happens after each reboot. Strange.

I did a clean install for 3 time! No solution so far.
