I haven't made a lot of test yet but I don't see that much improvement personally maybe it is because you had the stock rom before? There is a lot of crap on the stock rom of the t810 put by Samsung... When I brought it I rooted my tablet only to be able to clean it by deleting all those apps I had no uses for.

+1 on the fingerprint part I really missed it. That's one of the reason I choose that tablet.
[Galaxy Tab S2 Android Development] aldai2:
Does it means we may format sd card as adopatable on T810 ?
[Galaxy Tab S2 Android Development] sal82:
oh i definitely agree about the t810's stock rom being filled with garbage. if i remember correctly, it took up around 13GB! i mean jesus christ! WHY??!!:eek:
[Galaxy Tab S2 Android Development] legojoe8:
So what is the possibility of lineage 16.0/ 9.0 pie coming to the t710?
[Galaxy Tab S2 Android Development] schnoeselmeier:
Thank you very much for keeping the T-710 alive. I installed it today. Everything is GREAT so far!
[Galaxy Tab S2 Android Development] white09:
Works great on T810. Thanks ripee! :)
[Galaxy Tab S2 Android Development] ripee:
Unless bonuzzz posts some updated sources first, I'm too busy with real life for the next month to take on a big project like bringing up Pie from Oreo sources.
[Galaxy Tab S2 Android Development] metterschling:
FYI just tested if I could use the T715 with the 0121 LOS15.1 build as serial port monitor for a microcontroller. To my surprise this worked instantly! Grab an USB OTG adapter and the "Serial USB Terminal" app and you can watch the debug messages of your uC (here: ESP32 NodeMCU) module without requiring a PC.

Hey Guys,

I'm stuck on the blue/green screen of recovery mode after transferring TWRP via odin.

The device isn't responding to Vol Up + power + home to go into twrp recovery mode.

I've tried reflashing twrp via odin several times but no luck getting into TWRP.

Any help will be greatly appreciated.

Edit...

Flashed TWRP a few more times and it finally took.

Lineage is installed but can't get gapps to take.
[Galaxy Tab S2 Android Development] ripee:
Which gapps "brand" (open, mind the gapps, etc) and which package?
[Galaxy Tab S2 Android Development] hero913:
I was just coming here to post another update.

So when trying to install gapps, TWRP made a suggestion to install the "arm" version.

Went ahead and downloaded that one and viola!

I'm hoping that this OS makes the tablet faster.

Samsung slowed this living hell out of this thing. I used to love it back in the days but I find myself hating my experience with it when it was on touchwiz.

Any suggestion on how to "close all" option to appear at the bottom of the screen instead of the top when using the recent apps function?

Thanks for the quick reply! It's been a while since of done and mods to any android devices, so it felt good to get something like this done. :good:
[Galaxy Tab S2 Android Development] mfratto:
Solved: I had to update TWRP to the latest version. Then I could install LineageOS, Magisk, and OpenGapps. That got me where I needed to be. Thanks.

Help installing LineageOS on a Samsung SM-T810. Downloaded the files from the top of the thread. Followed the instructions to the letter. Try to install and I get an error:

E3004: This package if for devce: gts210wifi, gts210wifixx; this device is .

Any help? My tablet is, in fact, a SM-T810.

Thanks

Is it stock you're coming from or what?
[Galaxy Tab S2 Android Development] tamjan:
I stumbled upon the same problem of not being able to login after updating (from a 20201102 build). After restoring my backup, I removed the PIN and tried again. My tablet isn't encrypted. It complained about public keys and I had to explicitly re-apply magisk, but it booted and is seemingly working - except for Skype perhaps that crashes as start-up (but it did that before the upgrade as well :) ...). Haven't tried to add a PIN again yet.
[Galaxy Tab S2 Android Development] mfratto:
Stock, factory reset Samsung/Android 7.0 and TWRP 3.1.0.1 which I think was the last stable TWRP for this tablet. At least that's the last one I saw. Dunno if newer versions are supported.
[Galaxy Tab S2 Android Development] mfratto:

[Galaxy Tab S2 Android Development] Else717:
T810 from stock install twrp 3.5.1, then

Clean install lineage-17.1-20210308-UNOFFICIAL-gts210wifi, open_gapps-arm-10.0-tvstock-20210406, reboot.

can't boot with OS, only green string, then reboot and again twrp.

What's wrong?
[Galaxy Tab S2 Android Development] ArtoD2:
Why TVstock gapps?
[Galaxy Tab S2 Android Development] Else717:
Which one i need?
[Galaxy Tab S2 Android Development] ArtoD2:
Try Pico first.
[Galaxy Tab S2 Android Development] Else717:
Thanks, repeat all steps, it works))
[Galaxy Tab S2 Android Development] Ghale_ab:
Hi, I have installed Lineage OS on my SMT-715 tab s2 8.0 lite and its installed successfully but in cannot find wi-fi networks, when I restart my tab I can find networks but after a few seconds the problem is back rom: lineage-17.1-20210308-UNOFFICIAL-gts28ltexx

Edit: I try Install havoc OS also I got the same problem

Edit 2: i also try lineage OS 16 it is same thing

Edit 3: I try rom from another developer and wi-fi does not work also but it work on stuck rom
[Galaxy Tab S2 Android Development] danieljamesscott:
I'm getting the same behaviour here - wifi works for a short time and then fails to find networks.
[Galaxy Tab S2 Android Development] if_xda:
Hi ripee, I was trying to download the T810 ROMs but I got the error message that the download limit is reached. Can you increase the download limit or put the files to another place?
[Galaxy Tab S2 Android Development] lpedia:
This is a Google-imposed daily download limit, so ripee has no control over it. If you wait a day and try again, it will probably work.

What I do instead of trying to download directly from anyone else's Google Drive: right-click on the file and choose "Make a copy". The copy will go into your own Google Drive with name "Copy of <original name>". You should be prompted to log in to your Google account if you're not already logged in via that browser. You can then download or let it sync from your own Google Drive.

EDIT: I was wrong that Google would prompt you to sign in to Drive. You don't get a right-click context menu at all unless you're already logged in to Drive.
[Galaxy Tab S2 Android Development] if_xda:
Hi lpedia, thank you for the answere. I have tried both ways to day and nothing works. The download popup doesn,t apprear and the download doesn't started. Ad blockers were disabled. I have tried with firefox 87.0 (64-Bit). After then I have tried with chome and it has worked. It's little bit strange.
[Galaxy Tab S2 Android Development] dullknives:
new to the thread and have read a bunch of comments but i'm wondering if someone can give me an idea of which version of the T810 ROM is the most stable currently? looks like battery drain and wifi issues are still present for many T810 users with mixed results depending on the ROM version.

i'm currently fully stock and will be doing a full wipe install. thx.
[Galaxy Tab S2 Android Development] BURHAN77:
Ripee; Resurrection Remix Update? Thanks.
[Galaxy Tab S2 Android Development] lpedia:
Turns out that this is because you have to be logged in to Drive to get a right-click context menu. It's not the browser but Google itself doing this. Which makes sense when I think of it - it won't offer to make a copy unless there's already somewhere to copy to. :) I hadn't noticed this, because I always have Drive logged in on my default browser (Edge Chromium).

I'm guessing you weren't logged in to Drive on Firefox, but on Chrome you were?
[Galaxy Tab S2 Android Development] bmwdroid:
Just be happy when it's there.

Btw this is LOS not RR thread.
[Galaxy Tab S2 Android Development] JoshReuben:
But of a breakthrough on the wifi issue for gts28wifi. Someone here had mentioned that they've been updating each month with no issues, so I dirty flashed the January build, rebooted (it wouldn't let me log in with my screen pattern), powered off, booted to recovery and reflashed the March build, along with Magisk and Pico gapps. So far, no more disconnects or freezes.
[Galaxy Tab S2 Android Development] Iandriod:
I have successfully installed gts28wifi 20210221, clean install from stock Samsung, as per the instructions at the top of this thread. Oh what a feeling! It runs so much better, thank you Ripee.

I have not had any WiFi connect issues but I do get random re-boots that either lock up during boot (stuck on the Lineage logo animation) or it boots into TWRP recovery or Download. I've not had it crash during use, it always seems to happen while the device is asleep.

JoshReuben, were you having these re-boot issues? And did your dirty install fix it?
[Galaxy Tab S2 Android Development] entu19:
new build for T815 maybe with android 11 and lineage os 18.1?
[Galaxy Tab S2 Android Development] JoshReuben:
I was having occasional reboots, but most likely Firefox related. My big issue had been wifi drops, which dirty flashing prior versions and returning to March version solved.
[Galaxy Tab S2 Android Development] walidahmadi:
I am having a weird issue and there doesn't seem to be anyone who has had this issue and there is nothing in google.

I installed TWRP and flashed this ROM and GAPPS. I wiped dalvik.... and rebooted. However, now I can't get pass the initial wizard screen. I am stuck at the "Voice Search any time" screen. There is no button to proceed to the next step???? This is a very weird situation. I will reflash it and see if that helps anything. and Will update here.

Edit: Nope didn't work. Not sure what I can do as there is no way to skip this screen :(
[Galaxy Tab S2 Android Development] JoshReuben:
Aaaaand the wifi drops have returned on my gts28wifi. Very disappointing - doesn't render 17.1 unusable, but close.
[Galaxy Tab S2 Android Development] lpedia:
On my gts28wifi I've resorted to using MacroDroid to trigger a macro to check and reconnect wifi on boot and unlock. Once connected, it doesn't usually drop out while I'm actually using the tablet.

I still get BootAnimation loops from time to time. These are not actually reboots - it just gets locked into that loop after some system task dies. This often happens if I leave the device on and unattended, but I have had it happen while actively using it. At other times, but very rarely, I find it has rebooted to TWRP.

On a brighter note: battery life is very good when it's behaving (obviously it'll chew up battery if it's BootAnimation looping forever).
[Galaxy Tab S2 Android Development] lpedia:
Which version of Gapps? This does sound like a Google problem, but have you tried without Gapps to make sure LOS itself comes up properly?
[Galaxy Tab S2 Android Development] if_xda:
Hi lpedia,

today I have tried the following combinations:

not logget in:

- Firefox (87.0 64-Bit): I have tried to download files from original link from ripee -> doesn't work because the download limit is reached

- Chrome (89.0.4389.128 64-Bit): I have tried to download files from original link from ripee -> doesn't work because the download limit is reached

logget in:

- Firefox (87.0 64-Bit): with right click->download tried to download files from original link from ripee -> doesn't work, nothing happens, download doesn't started and no dialog appears

- Firefox (87.0 64-Bit): with right click->download tried to download copied files in drive -> doesn't work, nothing happens, download doesn't started and no dialog appears

- Chrome (89.0.4389.128 64-Bit): with right click->download tried to download files from original link from ripee -> works

- Chrome (89.0.4389.128 64-Bit): with right click->download tried to download copied files in drive -> works
[Galaxy Tab S2 Android Development] lpedia:
Very odd. What OS are you using? I was on Windows 10 when I tested Edge and Firefox. I just tried it with Chromium 89.0.4389.114 and Firefox ESR 78.9 on Debian (logged in to both browsers with a Google account), and right-click > Make a copy works on both.
[Galaxy Tab S2 Android Development] mutualexcrement:
Your wifi on?
[Galaxy Tab S2 Android Development] walidahmadi:
Yup. That was the issue. I figured it out after screwing around with it for 3 hours ;)
[Galaxy Tab S2 Android Development] yoshkapundrick:
Is there a systematic reason why several virus scanners find the Bluetooth system app as malware?
[Galaxy Tab S2 Android Development] Iandriod:
Rupee is doing such a great job of releasing monthly builds. I'm just wanting to check on the install procedure. I did the recommended clean install of the February build and now want to update to the latest April build. Another full wipe seems extreme. What's the best process?
[Galaxy Tab S2 Android Development] lpedia:
The usual procedure is that you must try with a clean flash before reporting any problems with a particular build. There haven't been any new issues reported for quite some time, though, and most of the existing issues have still been present in new builds.

I suggest you try a dirty flash, and if you have any problems do a clean flash to see if it cures them. I dirty-flashed the April build two days ago, and so far it seems stable. Fingers crossed ... :)
[Galaxy Tab S2 Android Development] if_xda:
I was on Windows 10.
[Galaxy Tab S2 Android Development] CuckooPenguin:
Is it just me - or is the last 810 release from april more instable with

* its wifi connection (dropping every hour or more and only to be reactivate by turnig wifi off and on again)

* random (reboots ?) while sleeping ..and ending up in boot animation ... to then be hard rebootet by hardbuttons only

Did not test it yet, but does a flash-over with an older image work (don't want to loose new apps and settings and since titanium root backup got worse ...) maybe a flash back works ?

If any one else have ideas for the probs above appreciate hints.

Thanks
[Galaxy Tab S2 Android Development] lpedia:
You could try Migrate to back up your current config. See [APP][ROOT][5.0+][1st Nov 2020] Migrate - custom ROM migration tool.

I don't know if a 'flash back' to an earlier build will work, but if it doesn't, at least you should be able to clean-flash and then restore with Migrate.

I have a T710 and haven't had any extra problems with the latest build. It seems much the same as the previous one, with one exception: fingerprint unlock is actually working now. It hadn't worked on my device with any of the previous LOS 17.1 builds.
[Galaxy Tab S2 Android Development] CuckooPenguin:
Thanks ! Did not know migrate yet and was looking for a decent replacement of titanium root. Will give that a try for sure hope another clean flash will fix the/my wifi issue.
[Galaxy Tab S2 Android Development] skas_2002:
Very nice ROM. T815 doesn't feel like a 7 year old tablet. The only issue that really bugs me - random reboots when screen is off. When I decide to use it battery is drained every time I forget to turn it off. Installed April 15 version, hopefully the problem will go away. Or maybe there is some registry tweak that may help me?
[Galaxy Tab S2 Android Development] lpedia:
The "random reboots" usually aren't actually a reboot - it's dropping into an infinite loop of the bootanimation logo, without rebooting first. This will of course drain the battery after a while. It doesn't just happen while the screen's off, either. I've seen it a number of times lately while actually using my T710.

Unfortunately, it's a known problem, still present in the latest build, and no-one has reported a diagnosis or solution. My only workaround is to turn the device off when not using it.

The other main defect is wifi not connecting automatically although configured to do so. Toggling wifi or off/on or airplane mode on/off usually forces the connection, and on my device it usually stays up then. Some OPs have reported wifi being more unstable than that. As above, no diagnosis or solution reported so far.

Another defect - a lot less common than the above two, at least on my device - is a sudden real reboot, which can be to system or to recovery. So you might find it in TWRP for no reason if you've left it on.

On the whole I still find the device quite usable, but I'm not depending on it as a daily drive. For me's it's mainly an e-reader, and it makes a very good one.
[Galaxy Tab S2 Android Development] crcowan:
I have a very similar experience.
[Galaxy Tab S2 Android Development] CuckooPenguin:
What he said :D

Did a clean fresh install - using Migrate to restore apps (thanks for the tipp)

sadly the wifi thing is bugging me still.

@ripee If you would need any logs or have some hints what we can check to help keeping this great rom alive - let me know. So far the logs don't tell me much.

Besides that - big thanks - for keeping our Tab alive and kicking .. not only as e-book-reader ;D
[Galaxy Tab S2 Android Development] bmwdroid:
@lpedia @CuckooPenguin

dunno if you've tried already but on my T810 I'm having Havoc3. 12 and no! problems.

Neither reboots nor WiFi issues.

Of course it's a bit older (February).
[Galaxy Tab S2 Android Development] lpedia:
Thanks, @bmwdroid - every so often I look at comparisons of LOS, Havoc, CRDroid, etc and usually don't see any particular reason to go for one of the others.

However, a more stable ROM for the T710 might just be that reason ;) ... so I think I will give it a try some time soon. It'd be nice if Havoc was getting regular monthly patch updates, though.
[Galaxy Tab S2 Android Development] bmwdroid:
Recently I learned (from the Telegram group where the dev ripee is a part from) that AOSP is the base for LOS and Havoc.

While crdroid and Resurrection Remix are just forks of LOS with differenting added features.

In that respect LOS and Havoc might well differ in their behaviour.
[Galaxy Tab S2 Android Development] lpedia:
They might well do so, indeed. Another reason for me to give Havoc a try. (y)
[Galaxy Tab S2 Android Development] lpedia:
@bmwdroid, I hate to report that Havoc isn't trouble-free either, at least on my T710.

I installed Havoc 3.12 (20210221) yesterday, and all seemed well at first. Wifi still needed occasional help to connect (toggle off/on), but seemed stable once connected. Battery performance seems similar to LOS, ie very good.

I left it on overnight as a test, and at first this morning I thought it had survived the night. But it dropped into a bootanimation loop as soon as I unlocked it :( (that's when LOS often does it on this device, too). Not a reboot - no Samsung boot splash.

Another behaviour similar to LOS: fingerprint unlock is unpredictable. Only works sometimes.

When rebooted after the loop, the device had airplane mode on, but I hadn't set that mode, and it hadn't come on of its own accord after any of yesterday's reboots. I haven't seen LOS do that.

Anyway - I'll go back to LOS, as Havoc doesn't seem an improvement in any other way, and LOS has at least been getting the monthly patch updates.
[Galaxy Tab S2 Android Development] bmwdroid:
Sorry to hear that.

On my T810 I'm having none of these issues.

I turn WiFi off and it lasts a week and more with intermediate usage during which it immediately connects to WiFi when turned on.

Fingerprint btw I don't use.
[Galaxy Tab S2 Android Development] lpedia:
I had hoped that since the T710 and T810 have almost identical hardware apart from screen size, my device would behave with Havoc, too :( - but am not too surprised that it didn't.
[Galaxy Tab S2 Android Development] Max_C:
This problem only for last LOS? I have the same problem - infinite loop after some time and battery drain. Which OS does not have this bug?
[Galaxy Tab S2 Android Development] lpedia:
This series of LOS 17.1 builds have had this problem all along. It has become a little less frequent with the later builds, but hasn't gone away. I tried Havoc 3.12 (= Android 10 based, like LOS 17.1) on my T710 and after half a day saw it do the infinite bootanimation loop, but @bmwdroid has a T810 with Havoc 3.12 that hasn't had any problems. You should try it - you might be lucky too.

Can I have the link of the last lineage os 16 for the T715?
[Galaxy Tab S2 Android Development] XDroidA:
SM-T815 and flashed latest lineage-17.1-20210509-UNOFFICIAL-gts210ltexx.zip

Shows error starting:

Decryption unsuccessful

The password you entered is correct, but unfortunately your data is corrupt.

Flashed back lineage-17.1-20210415-UNOFFICIAL-gts210ltexx.zip and tablet working again.

What's wrong with the latest build? Anyone having the same problem?
[Galaxy Tab S2 Android Development] MrBlubke:
SM-T810 here and no issues installing latest build, not sure if anything is fixed yet though...

are you certain it was uploaded completely when you downloaded it? maybe it was still being upped? so you didn't get the complete build? I don't know, just guessing since it's pretty recent...

have you tried downloading the build again?
[Galaxy Tab S2 Android Development] XDroidA:
I re-downloaded the file and it's identical to what I flashed.

lineage-17.1-20210509-UNOFFICIAL-gts210ltexx.zip SHA256: E0B36F5206915E314D93F94966DB10749B757BAB391F35E4F58345D98D360FB2

"Decryption unsuccessful" refers tablet's encrypted /data partition. Latest build cannot open and decrypt it for some reason. Previous build can open and decrypt it successfully.
[Galaxy Tab S2 Android Development] Surfer_II:
Have flashed lineage-17.1-20210509-UNOFFICIAL-gts210ltexx.zip on T815 successfully without any issue.

Please double-check if you have installed latest TWRP version twrp-3.5.2_9-0-gts210ltexx.img and maybe the actual Magisk 22.1 (in case you use this root tool) as well.

This combination seems to work, at least on my tablet.
[Galaxy Tab S2 Android Development] XDroidA:
I have the same TWRP version. Do you have tablet encrypted?
[Galaxy Tab S2 Android Development] yoshkapundrick:
With the 4/15 update mine hung for a few minutes then rebooted into TWRP. I thought it was a fluke however it just did the same thing with the 5/9 update. I just did a straight update with no other actions. What am I doing wrong?
[Galaxy Tab S2 Android Development] bmwdroid:
What I would do:

1 Make a complete backup (remember that files in folders "Download and DCIM" might not be included) in TWRP first then

2 wipe system, cache, dalvik.

3 Flash ROM, Gapps, Magisk. (Each app setting will be kept)

If that doesn't work

Repeat 2 and additionally wipe internal storage plus "Format Data"

3 with intermediately rebooting/testing after each step.

When everything works restore "Data" via TWRP.
[Galaxy Tab S2 Android Development] yoshkapundrick:
Method #1 worked perfectly. Thank you so much.

Is it likely that this will be the method I will have to use in future updates?
[Galaxy Tab S2 Android Development] Surfer_II:
No, mine is not encrypted.
[Galaxy Tab S2 Android Development] bmwdroid:
Well, I don't really know if it's necessary, but found this way for LOS17 +18 more appropriate as resulting in less (if at all) issues.

On 14.1 I usually flash very (no prior wiping) dirty just new LOS onto old one only wiping cache/Dalvik afterwards.
[Galaxy Tab S2 Android Development] fabi500:
Hi,

i switched also back los 14. works perfect without any batttery drain.

In my 815 i didn't get ios 17 Working properly.
[Galaxy Tab S2 Android Development] bmwdroid:
I didn't switch back.

Havoc is great on T810.

My 14.1 mentioning was just for what I do on P900 and P605.
[Galaxy Tab S2 Android Development] diablosblade:
ok - spent a while searching this thread but cant find the simple answer i probably need.

finally going to do something with my t810 - i want to clean install 17.1 but the instructions for the recovery mode list wipe options i dont see? wtf am i doing wrong...... hate it when samsung makes feel like a noob
[Galaxy Tab S2 Android Development] bmwdroid:
But TWRP is installed, isn't it?
