I installed 19.1 a month ago/ yesterday i updated and when i tried to update i just noticed there was no twrp installed so i updated it from system 19.1 by pressing side keys because unfortunately touch can't do it, something is not calibrated properly / after that update i uploaded twrp and opened it before booting and clicked restart recovery and then reopened twrp next step was to restart system in twrp and then from system i clicked restart recovery but unfortunately twrp is missing (few versions of twrp i checked and always the same / i didn't upload system but only twrp so i couldn't click system recovery when installing 19.1)

I'll try again next week to reformat everything and install twrp then upload 19.1

But I don't think it will help (it's like 19.1 has a security feature that won't let you delete the original recovery)

Unless is a switch recovery block in the system developer options But I haven't seen anything like that
[Galaxy Tab S2 Android Development] bmwdroid:
Well mine is and always stays on TWRP.
[Galaxy Tab S2 Android Development] cndv:
If I have time today, I will try to upload twrp &wipe & install 19.1
[Galaxy Tab S2 Android Development] cndv:
Works and does not remove twrp now

As you wrote, this is set during the first installation

Or

After installation you can also disable twrp overwrite

Cheers for the new update retiredtab I am going to try this in the next few days, I've been getting a lot of random reboots and system freezes with the last update. The reboots just happen no matter what I am doing and all I mainly do is browse the net, the freezes are when I have left it for a few hours come back picked it up and it's just froze can't do anything until I reboot it, so will try this new one in a day or so and see how it goes.
[Galaxy Tab S2 Android Development] retiredtab:
There's been no T810 device tree code changes since Aug 27, 2022. If you are having random reboots, it's likely your application(s) or something is corrupt. I suggest a clean install where you format data in TWRP and reinstall your applications vs restoring from backup.

I use Brave browser and it works fine.
[Galaxy Tab S2 Android Development] retiredtab:
@lojelo , if all you are doing is browsing the net, I suggest this.

1. Save data to external sd or external PC.

2. Format data in TWRP.

3. Wipe all other partitions.

4. Download Jan 2023 buid.

5. Install Aurora Store 4.1.1 from https://gitlab.com/AuroraOSS/AuroraStore/-/releases

6. After installing Aurora Store, install Brave browser using Aurora Store.

7. Use this configuration for a few days and there shold be no random reboots.

8. If all this works for a few days, then something in your backup or other apps is causing the random reboots.
[Galaxy Tab S2 Android Development] bmwdroid:
I updated to Dec version half dirty (wiping only system and caches) like I updated the versions before.

Always full backup anyhow.

No probs, reboots, freezes at all.

Vivaldi and Brave as browsers.

WhatsApp as coupled device works as well.

Whats the state of the battery like when that happens?
[Galaxy Tab S2 Android Development] lojelo:
Will try that retiredtab thank you

Yeah I had the same thought of it being an app or 2 causing these random reboots I don't use that many but most of the time when it reboots is when I have been using chrome beta I have tried normal chrome and that's worse things are ok using firefox but I will give Brave browser a test on the next install in a few days.

Question regarding Brave, does it let you import bookmarks of passwords from other browsers? I have used it years ago but it never let me import any bookmarks of passwords from another browser.

The random freezing the battery could be at 90% and it would still freeze if I left the device alone for a few minutes to a few hours, it just won't let me do a thing hence having to reboot it and it's fine again.
[Galaxy Tab S2 Android Development] retiredtab:
Brave is based on open source chromium (same as Chrome), but without all the spyware/telemetry that Chrome adds to their offering.

If you're using gapps, it could also be gapps that's crashing. We remove that entirely by using Aurora Store.

I have a simple setup: Aurora Store, Brave browser, newpipe (for watching streaming content). All are open source, ad-free and user privacy friendly/oriented.

I believe so, but I don't use it on my Android device. I use Brave on my desktop and use a 3rd party open source password manager vs the built-in one.

Bmwdroid is probably thinking of a weak battery, but if it's rebooting at 90%, I would say that's not likely the case.
[Galaxy Tab S2 Android Development] pflyaz:
Hello all.

I wanted to provide some updates to the T810/T710 LOS community.

Context: I have been using the great work of @retiredtab and @lpedia to provide LOS 18.1 and 19.1 for the excellent T810 and T710 tablets. I have both tablets and have found the 18.1 ROM to be excellent and very reliable for daily use. The 19.1 ROMs are excellent, except for one thing - regular (every few days) “Connected to device. Can’t provide internet” errors with ! on wifi icon. A reboot didn’t fix it every time, and I sometimes saw multiple reboot crashes before I got a clean wifi back again. WiFi would stay on for a while, and then something triggered the fault. I have not been able to identify what.

I decided to do a clean install on both my T810 and T710 of the LOS 19.1 ROM, to start the year clean. I had been doing dirty installs for several months since the original alpha ROM was released. I can report the following which is really an update to my post on the install instructions earlier.

NikGApps Core 20220908 doesn’t properly install PlayStore – in TWRP says it installed but it doesn’t show as an App on home screen – 20220709 is the only NikGApps version that works for me. No version of MindTheGApps works.

NikGApps up to Omni works. NikGApps Stock and Full don’t – they replace AOSP key board with Google Voice typing which you can’t get rid of. But even with Omni the included Apps don’t appear on the installed apps screen. So my recommendation is that you just use NikGApps 20220709 Core and load the Apps yourself.

After initial setup, I recommend quickly enabling Google backup. Otherwise, SeedVault jumps in and you can’t get rid of it.

Before my clean installs of LOS 19.1 using 20230107 (T810) or 20230108 (T710), it often took multiple reboots and/or power off to get the tablet to restart properly with WiFi enabled. After clean installs of 2023010X with NikGApps 20220709 Core, both devices now recover cleanly with a single reboot if the WiFi fails. It would be nice if the community can track down the culprit for what triggers “Can’t provide internet”, but until that’s found at least a single reboot will restore WiFi functionality.

Apart from the WiFi anomaly, I have experienced no other anomalies on either my T810 or T710 running LOS 19.1 since the clean installs. Thank you again @retiredtab and @lpedia for your great work. It's really appreciated.
[Galaxy Tab S2 Android Development] bmwdroid:
My T810 is just a bedside device and usually in flight mode but whenever I turn on Wifi it connects and for one hour or so it stays stable until I shut it off.

Don't encounter reboots either.

Think I'm gonna use it longer today to test.

How long does it take yours to get the problems?

Did you pull a log after Wifi crashes? Might help @retiredtab to identify the problem.

I prefer Syslog from F-droid btw.
[Galaxy Tab S2 Android Development] crab-it:
I have followed this installation steps, on my T810 and also have exactly the same problem. If @retiredtab and @lpedia want any help in providing logs to look at the problem I am happy to try and help.

[Galaxy Tab S2 Android Development] chappatti:
1. I can confirm the WiFi issue here too. Reboot required to fix.

2. NikGapps issues too. I fixed it in a post I reported earlier.

3. Random reboots....but seems to be closely associated with Kindle app that I use for reading. So I can live with it.

Thanks anyways for a GREAT upgrade to my Tab S2!!

3. Use stock android.hardware.power for CPU/SoC management so little cores can go as low as 400Mhz. Previously, the minimum clock speed was 1200Mhz and this may have caused some overheating. See

https://github.com/retiredtab/andro...mmit/8480e024cb15d82b9d418c44efd9257db173b49e

4. There has no been no fix for the “Connected to device. Can’t provide internet”. DO NOT ASK when this will be fixed. If/when it is fixed, it will be announced publicly in this thread.

If this is problem for you, go back to 18.1. In addition, the problem might be a memory leak so the less apps you have installed (like gapps), the better. I rarely see this problem as my setup is very simplistic. I just have Brave browser, Newpipe and Aurora Store.
[Galaxy Tab S2 Android Development] jirinaforever:
Can concur - tried both 19.1 and 18.1 on T810.

19.1 has some issues, namely wi-fi, and frequent crashing when playing around with Play Store or other Google services, but most importantly for me - it's faster than stock in that it doesn't lag as much, but it feels just as sluggish processing stuff (maybe bit faster, but nothing stellar). It's great for the new features like gesture navigation, but the paint hasn't dried and it's still being worked on, keep that in mind.

18.1 on the other hand... working gapps-pico (from the guide), was able to set up the tablet the same way stock was (I use Google Home for home automation, Google search on homescreen, gboard), rock solid, stable (even when using gapps), and most of all it's lightning fast - as in no lag on wake up, tablet just hustles to get stuff done and you can turn on "High performance" battery mode that just makes the tablet fly.

If you want the newest and greatest Android features - go for 19.1.

If you want to revive your aging Tab S2 and use it as your daily driver and make it snappier and happier - go for 18.1.

Hello,

I installed the 19.1 Rom and it works, thanks.

I just had quite a hard time to get gapps to work, especially google play store. When I managed to install some gapps package, I always had the problem that Google play store would get stuck on pending, so i wasn't able to download any apps.

I found my own way of getting it to work, maybe it is a bit too complicated, and there is an easier way, but after a lot of trial and error i found out that this works for me.

1. Clean flash ROM.

2. Boot into system.

3. Boot inte recovery install Magisk.

4. Fully install magisk app. enable Zygist. reboot.

5. Install MagiskGapps package. I installed the Basic version.

https://sourceforge.net/projects/magiskgapps/

(this only installes google play services, on my device)

6. reboot.

7. Install Google play store APK from APKPure newest version.

if you open the newly installed play store, the app will just crash. so...

8. reboot

9. open play store, login, and now installing apps from play store should work.

Maybe not all of the steps are really necesarry, but this works for me, if someone got an easier solution, let me know.

Or if someone can confirm this procedure works, let me know.

Thanks.
[Galaxy Tab S2 Android Development] lpedia:
Did it 'stick' forever? In some cases, I believe you have to wait (quite) a while for Play Store to get its act together and update itself to the latest version. Another possible cause is that - for some reason - Google Play Store and/or Play Services didn't get all the permissions they need, and you have to manually add network access permission.

I don't have a T810, but can comment on Gapps for T710, which should be similar.

For some time, I've had difficulties with LOS19.1 on my T710 and my preferred Gapps packages, NikGapps and BiTGapps. The former would only work if I used the July 2022 package, not the (then) latest for Android 12.1, which was September 2022. After flashing the September one, the device would go into a boot loop on booting system. BiTGapps, on the other hand, would refuse to install at all, saying there wasn't enough space.

There's been a lot of work done n NikGapps recently, and I found the current core version installed easily and is stable on 19.1 on a different device (an HTC 10) - with clean flash ROM and flash NikGapps before first boot. I have not yet tried it on the T710.

I have no experience of MagiskGapps, but I see that it's derived from NikGapps, so I think someone on the NikGapps thread https://xdaforums.com/t/android-13-gapps-nikgapps-arm64.3915866/ might be able to advise you about the best procedure for installing it. I'd hope that it doesn't need clean-flashing the ROM every time.

Good luck! 🙂

[Galaxy Tab S2 Android Development] codiflow:
Thanks for pointing that out.

Just tried it but decryption of data partition in TWRP 3.7.0-9 still fails. Don't know if it makes a difference if Android would have been flashed with 3.7.0-9 instead of 3.6.2-9 but with flashing 3.7 over 3.6 after having an encrypted data partition definitely fails with "Password failed, please try again!".

I personally can live with this restriction and maybe it will be fixed in a future release of TWRP.

Does it make sense to mention that tutorial in one of the first posts for others starting to flash this ROM? I personally love to have all relevant information and links bundled in one of the first posts as mostly I don't read through all following posts because of time (especially if there are plenty of pages).

Apart from that thanks for this ROM – works like a charm as far as I can tell 🥳
