Flashing the newest TWRP version available for the tablet will get rid of the error.

1. The safest way is to follow the instructions.

2. I've never used magisk on any of my devices. The superu addon works for me. But magisk has a few more features.

QUICK NOTE:

Since I have the same tablet(T810), be sure to uncheck the "install TWRP as a system app" option. If you don't, you won't be able to boot into LOS.
[Galaxy Tab S2 Android Development] shtay:
Which download would I want for the 817 variant?
[Galaxy Tab S2 Android Development] jenom:
I can confirm both the problem and the solution. Maybe it's worth mentioning in the install instructions.
[Galaxy Tab S2 Android Development] sal82:
I agree. This step should be in the instructions.

Last year it seemed that the fingerprint sensor had little likelihood of being fixed (https://xdaforums.com/tab-s2/development/rom-lineageos-15-1-t3879302/post80913659#post80913659), but I was surprised to discover that it works fine on another Tab S2 (albeit a T813 running LOS 17.1)!

I appreciate that this Tab S2 has a different chipset but I'd be surprised if it had a different sensor, so surely the driver appears to have been fixed? Could it be merged/backported/whatever the correct expression is?

Ditto with the capacitive button lights.

Really appreciate you guys for doing this. Can someone point me to a build guide for this ROM? I'd like to make some changes on my own but I'm totally inexperienced in the ROM world. Thanks!
[Galaxy Tab S2 Android Development] ripee:
Log in with your google account before downloading, or add the gts210wifi folder to your own drive as a shortcut.
[Galaxy Tab S2 Android Development] aryanmalik:
When updating unofficial builds is it ok to just flash the latest zip or should I perform a clean install even just for an update?
[Galaxy Tab S2 Android Development] ripee:
You can flash the new one on top of the old one, or clean install, up to you.
[Galaxy Tab S2 Android Development] computersalat:

OK. Where is the TWRP 3.3 link in OP? Sorry, if I am not wearing my glasses, but I just dont see it !!?? :confused:

[Galaxy Tab S2 Android Development] sal82:
That's because TWRP is not in the OP.

Go to the link below and download it for your tablet.

TWRP also has an app that you can download from the play store.

Hello,

I noticed something strange when I boot on my SM-T810, several times already, if the tablet is in landscape mode, bootloop.
[Galaxy Tab S2 Android Development] chappatti:
Thanks! I used the Twrp app, but got stuck with a kernel error during reboot into recovery that required reflashing the image via Odin to allow normal boot. This was the working method for me on my Tab. This caused me to post if there was a specific image to use. All is good now.:good:
[Galaxy Tab S2 Android Development] akgxd:
Hello there,

I tried your method last night and after hours of research (I have never performed this) I managed to install this OS perfectly. Now, my galaxy tab s2 looks and feels better than ever. Super smooth. I thank you so much and to all the developers.

I have only experienced... minor bugs? E.G.: sometimes the fingerprint sensor will not work, yesterday the tablet just turned off and was stucked on a loop screen that said "restarting tablet". Anyway, I still have some questions and I would like someone to answer me. What is that magisk program? I did not downloaded nor used when installing the lineage os. Then, when I boot up the tablet, I get this to notifications that say something about some Selinux enforcement that is disabled. What should I do?

Thanks in advance.
[Galaxy Tab S2 Android Development] CuckooPenguin:
Check under Settings->Security->Trust - at the bottom you can disable the selinux warning.

Will Disney + streaming work while using this ROM?

Just a little bit of background. I have a SM-T710 Tab S2 been rooted for ages on stock ROM. Used root to debloat and do some thing like get rid of awful Samsung Emojis in Nougat. However recently due to subscribing to Disney+, even after switching to Magisk and passing SafteyNet, I can't use Disney+ without reverting to the Official ROM status. Which I have done so. While I'm not super fussed with root I do hate how bloated the Samsung ROM is and how awful the emojis are... Things I fixed with root. What I am wondering is if I switch to Lineage can I enjoy the benefits of a newer Android and cleaner ROM but also still access Disney+ or is it gonna spit out it's dummy because my device is not official and is that gonna cause issues with SafteyNet and Widevine? Basically for anybody running this ROM on SM-T710 can you access and stream Disney+ in HD?

[Galaxy Tab S2 Android Development] ceanth:
Hi all,

I'm considering getting a tab s2 (t710) and plan on installing Lineage 16.0, how well does the tablet run day to day?

My plan would be to use Netflix (I understand HD isn't supported on this tablet), some very light browsing and YouTube.

I currently have a Lenovo S8 so wondering if it will be much of an upgrade from that.

Thanks!
[Galaxy Tab S2 Android Development] sal82:
I can't speak for the T710 owners, but my T810 runs as smooth as it gets. And I'm a heavy user.
[Galaxy Tab S2 Android Development] bbortnick:
it runs pretty well on my t710. crashes a couple times a week, otherwise pretty smooth and responsive. The aspect ratio is good for reading books and web pages. I installed a Netflix apk and it runs fine.

I have installed the unofficial lineage by ripee as it is not officially supported. It has a few small issues:

the two hard buttons do not always light up. reboot to fix.

The fingerprint scanner does not work to unlock

the mic does not work well, cannot do Google meetings

[Galaxy Tab S2 Android Development] CJH500:
Was it working in HD and assume you mean on Lineage, was it with or without root? Still confused as to why my root with even with Magisk Hide was causing the app to no want to play anything. That's why I wondered if it be to do with Widevine but I could not even get SD playback.

T715y 20200609 Rom version

- Fingerprint scanner still not fully functional

They do registered, but it will have no response after a deep sleep. Only work after a short screen lock, and also unlocked quite slower than stock.

- Mic is full of boosted noise

but it's not bother me much. Driver problem is understandable.

Thank you so much for your efforts anyway. Other than this everything is snappy and stable. Looking forward for the your kindly improvements. :)
[Galaxy Tab S2 Android Development] kabelgleichung:
I second that request, as channel 13 is most usable here in my house due to other WiFi networks.

Any chance to change the regional settings?
[Galaxy Tab S2 Android Development] FreakyxD:
I just had the same issue with a black screen using the latest GAPPS (Stock) for the T810. The reason was a problem with Android System WebView as you can see in the gapps log:

NOTE: Stub WebView was installed instead of Google WebView because your device
has already Chrome installed as WebViewProvider. If you still want Google WebView,
you can add 'Override' to your gapps-config to override this redundancy protection.

First, I skipped logging into google services during initial setup. Then I sideloaded the "Android System WebView 83.0.4103.106 (arm-v7a) (Android 5.0+)" apk from APKMIRROR

(I was somehow missing Google Chrome, so I had to copy the APK onto my tablet via USB). Then, I was able to complete the google services setup and overwrote the apk with the one from the Play Store.
[Galaxy Tab S2 Android Development] Fapcorn:
Hi. I’m having some sort of problem here i stalling the GApps and booting up the freshly installed OS on my SM-T815. About that, it seems to be stuck in some sort of “boot loop”. It keeps on loading during start up and then reboots back to TWRP. And then GApps. I can’t install it due to Error 20. I’m very certain that I followed every pixel in the instructions on full wipe with an external SD card. Not sure if this thread is still alive, but any help would be appreciated. Thanks!
[Galaxy Tab S2 Android Development] sal82:
Uncheck "install TRWP as a system app" when prompt to install it during the installation process. That should get your tablet up and running.

About gapps, update TRWP. If that doesn't work, try another package.
[Galaxy Tab S2 Android Development] FreakyxD:
To add something to sal82's answer; make sure that you are using the correct version of gapps. For this ROM you need arm 9.0.

Also, if run into a problem later with a black screen during OS setup, my post above yours might help here: https://xdaforums.com/showpost.php?p=82883751&postcount=1133
[Galaxy Tab S2 Android Development] Fapcorn:
Just some feedback

Hi! So, I finally managed to successfully install this ROM 2 days ago on my T815 and everything is working and looking perfectly except for some minor to slightly concerning bugs and missing features in my perspective and they're the only ones I'll mention as suggestions. I'll start with the mic:

So the Recorder app doesn't work for me but the internal mic does pick up sound normally on Chrome, but not with headphones, it still picks up from the internal even when plugged in.

Next is the camera app, nothing serious, but as mentioned by others, shutter button is still not positioned properly.

About the locked screen, I think it suspends some background apps, specifically my Buttons Remapper, which I use to prevent my broken volume buttons from accidentally registering unwanted key press, but I'm not sure if it's the app's or system's issue.

Another thing is the Goggle Assistant doesn't come out when I long press the home button, and yes, my home button works. I already enabled the action in the settings and the Assistant does work when I say "Hey Google".

That's all I remember for now. I don't know if this ROM is getting updates, but I'll post issues I experience so they'll be known.

*Also, quick question: does anyone know how can I get photos synced on my Samsung Cloud? Dumb me backed up my files there instead of my SD card. I read somewhere that it's only possible on stock Samsung ROM, but I'm hoping someone knows any workaround since Samsung Cloud web version has limited accessibility right now.
[Galaxy Tab S2 Android Development] blackspp:
I have Lineage running for some 4 months now. Although Lineage is great the S2 is really reaching the end of its life with me. It is slowing down more and more and a factory reset only improves performance for a few weeks before it starts crawling again. Now looking for a more recent tablet with good specs, small bezel that can run the latest Lineage. probably a Samsung again.

team,

I am at the end of my wit. I can't figure out why it is that when I go to ADB sideload (swipe to Start Sideload), my SM-T810 tablet disconnects from my windows 10 laptop.

I was only able to sideload the OS once. But I am not able to do it anymore.

What am I doing wrong?

Is there an alternate way to sideload the OS?

Please help, thank you,

Hi everyone.

This is my secound post in this forum.

I installed this ROM today on my T-710.

I have one, very important question. 2.4Ghz WiFi doesn't work for me, only 5Ghz works. Is it supposed to be there?

I installed another ROM: AospExtended ROM V6.7 yesterday but the problem was the same.

How to solve this problem?

Use WiFi channels 1-11. Channels 12-14 are not supported with this ROM.

Am abandoning this rom as it gets worse and worse. Thanks for the efforts though
[Galaxy Tab S2 Android Development] JoshReuben:
Ciao Junior.

This ROM gets better and better.

Learn a little more before running your mouth, and spare the rest of us the process.
[Galaxy Tab S2 Android Development] JoshReuben:
The devs and posters are all volunteers here, and you've received numerous attempts from numerous posters to help with your problem. Others cannot reproduce it and for most of us, this rom works very well, better than stock, and has added years of useful life to our ageing expensive S2s.

So if you can't solve your problem, that's a shame. But don't insult everyone here with "gets worse" language. It's not true, it's not helpful or constructive, and it demotivates those who are doing the hard work that the rest of us value highly.
[Galaxy Tab S2 Android Development] Patrick010:
I only mentioned that the problem got worse for me. Aparently thats not allowed.
[Galaxy Tab S2 Android Development] MrBlubke:
well, if you say you're abandoning the ROM so I don't see the point... you seem to be the only one having that bad experience on a ROM that's been made by users, where the original developers already abandoned the device for quite some time. Additionally quite some users have tried to help you and from what I've read you haven't really provided much information about what you've already tried and where you've tried to find information. the people that've tried to help you are not payed for that service, they are not the developer for this ROM either...

So when you say you're abandoning the ROM and say it's only getting worse, you give a slap in the face of both the developer of this ROM and the people that tried to help you. you also seem to be blaming the ROM where as I mentioned before it's working amazing for us. And thr most recent Android for our device, giving us an experience the device creators never gave us.

just sharing my thoughts...
[Galaxy Tab S2 Android Development] yertar:
Thank you!!!

First off, a big thanks to the developers for putting this together. It's amazing to get an OS update after all these years, and it's breathed new life into my aging (but beloved) Tab S2.

I'm quite new to this so I wanted to flag a couple of bugs. I used the installation guide posted in this thread, except at the end I used the instructions on the first post here to do a clean installation. https://xdaforums.com/tab-s2/general/t713-prolly-install-twrp-lineage-os-t3935020

I'm using a T710, and I installed lineage-16.0-20200714, without addons, and OpenGapps stock version 20200711.

Bug 1: Installing with TWRP 3.4.0 caused a boot loop. TWRP 3.3.1 worked fine. When I installed using TWRP 3.4.0, the Lineage OS logo ran for a few minutes, and then it rebooted into TWRP. Further restarts did the same. (I also tried with the June 9 lineage build and had the same loop.) No boot loop with TWRP 3.3.1.

Bug 2: Perhaps related to the above, when using TWRP 3.4.0, the clean installation instructions on the first post yielded an Error 7 when trying to install immediately after the "format" step. To clear the error, I had to restart after formatting, then wipe, and could then install the OS. The clean installation instructions worked fine with TWRP 3.3.1.

Bug 3: The hardware button lights worked only on the first load. On subsequent resets, I couldn't get them to light up again, even after checking the backlight settings under "Buttons."

Edit: I encrypted my tablet and after restarting, the lights now work again!

These bugs are all very minor, of course. Just wanted to flag them, with thanks again for all your hard work on this!

As Yertar, I had to downgrade TWRP. I had problems with start up after installing lineage is 16, I ended up solving the loop by DL stock android from Samsung. I installed TWRP 3.3.1 and used ODIN to install everything.

Now I have a whole 'new' smooth running tablet. I am very satisfied. Will there be an auto update our will I have to do the process all over again, when a new version is out?

Thank you developers, good job ??
