Thanks again ripee!

Updated to 0423 this morning and all works very well.

The only thing is the "Android Auto is using battery" notification all the time but in checking, it's 0%. so no issue really just the notification.

Camera is now fully working, front and back switching working.

Help

Newbie messed up.

I wanted to update TWRP with new version 3.3 using the image file but I selected the wrong partition.

Thought it should be Boot but obviously that was wrong.

Now on boot screen I get Galaxy Tab s2 Powered by Android and on the top of screen in red is

"Kernel is not Seaandroid Enforcing " Tab is lock on that screen.

Is there anyway to fix or am I bricked?

Thanks for any help

[Galaxy Tab S2 Android Development] Rew482:

But sure would like to know how to update twrp.

I do find one issue that I have not been able to resolve with 423.

Google Photos crashes on start. I've cleared cache and data but makes not difference.

I also have tried various releases of Gapps and they all end up with the Photos app crashing.

I also tried loading Rom and rebooting and then loading Gapps as was indicate elsewhere.

Also did it all as a clean install, not restoring the backup.

Rew

Any idea what to do to fix?
[Galaxy Tab S2 Android Development] scottfk:
Have you granted any permissions to Photos? It has Contacts, Location, Phone, and Storage on mine. It works just fine.
[Galaxy Tab S2 Android Development] Rew482:
I tried granting permissions to Photos and clearing cache & data and I still get "Photos has stopped -Open app again" and restarting.

When I was on 408 Photos worked but on 423 it has always crashed upon starting.

Install went well. Didn't root, just unlocked bootloader and installed TWRP 3.3.0 using Odin, then did a backup with TWRP before installing this ROM + pico OpenGapps (ARM). So far, everything seems to work fine, including fingerprint scanner and bluetooth keyboard. THANKS!

Two questions [MENTION=6005084]ripee[/MENTION]:

- Any chance of you doing the updates on LineageOS.org?

- Do you have any plans to do LineageOS 16 for the T810?

Thanks again for your great work!
[Galaxy Tab S2 Android Development] ripee:
There is zero change of gts2 ever receiving official support, given all the patches we have to apply just to get it to build, let alone function with enough stability for daily use.

lineage-16.0 is being worked on, but it is slow going since we are basically re-inventing the wheel. It's not as easy to build upon previous exynos sources than qcom sources, for example.

[Galaxy Tab S2 Android Development] :
First of all, thank you ripee for making our trusty old S2 still relevant today. I flashed the latest build a few days ago and it's been working really good so far. But ...

I can confirm that on my 810, the fingerprint unlocking doesn't work: it doesn't even show that the fingerprint isn't recognized, it just stays mute. The only way I managed to briefly make it work is by opening the camera from the lock screen, like chigo58 did, and going back to the main lock screen page.

Nothing fancy about my setup: fresh install, magisk (for adaway) and standard apps, no system mods. Glad to help in any way I can if needed.

Is the deep sleep problem for t815 solved?
[Galaxy Tab S2 Android Development] roguetr:
I don't think so ... Mine drains pretty fast when not in use.
[Galaxy Tab S2 Android Development] StathisA:
T710

I do believe that there's a problem with VPNs (created in the settings menu) - they go "unsuccessfull" very fast - as others have mentioned.

VPNs created in "OpenVPN" app are working fine.

Another issue is that its very hard to create "groups" of app on the home screen, needs multiple tries to group but i think this is a problem with Tribuchet rather than the rom itself.

Since VPN is essential to me to connect to resources, i'll go back to stock - but this looks and feels very nice and would love to come back after it is fixed.
[Galaxy Tab S2 Android Development] tzlot:
Thanks for the great Rom! Noticeably more responsive than TW [emoji106]

Can confirm the same fingerprint oddness, and google photos is not working for me (waiting for an update as per a prior post) I wasn't going to bother with magisk, but it seems to be required for Netflix in case anyone else is having problems.

Any suggestions for underclocking? I used to use Samsung game tuner to dumb things down a bit & cut down on heat /battery drain when gaming... Any suggestions would be most welcome!

[Galaxy Tab S2 Android Development] garrahan90:
I have heard all these great things about custom ROMS over here but never tried because of bricking fear. Now I decided to take a shot a it, so I found this post which contains the lineage os needed for my device version.

*1. Move any files you want to keep to your Home PC - ! Or you will lose them !

2. Download your LineageOS Rom and GApps Package,

3. Move your LineageOS Rom and GApps Package to the internal storage,

4. Boot into Recovery Mode,

5. Wipe > Advanced Wipe > Select On (enable tick) for Dalvik / Art Cache, System, Data, Internal Storage, Cache,

6. Swipe to Wipe at Bottom of Screen,

7. Back to Main start screen,

8. Wipe > Format Data,

9. Type 'Yes' and press blue checkmark at the bottom-right corner,

10. Go Back to Main Start Screen to Install Rom and GApps,

11. After you have finished installing the Rom and GApps > Wipe Cache/Dalvik > Swipe to Wipe,

12. Reboot System! Enjoy!

13. Once first boot is completed you can safely move your files back onto your Internal Storage.*

Is it this simple or am I missing it? Are there any more steps? I remember watching a custom ROM video long ago using usb debugging and terminal, is that still necessary?

Sorry if I am too ill-informed, and was not supposed to ask this here. Just wanna make sure I do it right.
[Galaxy Tab S2 Android Development] ripee:
This is exactly where you're supposed to ask if you're unsure! :) Additionally, if you want to root, download the su addon in the OP, or Magisk, and flash it after flashing the rom zip.
[Galaxy Tab S2 Android Development] roguetr:
That guide is pretty close but assumes you have TWRP recovery already installed. To install TWRP you can use USB debugging and ADB which is what I did. Apparently there is also a Samsung app (Odin?) which you can also use to accomplish this.

You can install TWRP without affecting your installed OS, so focus on getting that part right and then use TWRP to backup your existing environment. It's good practice and when you transfer any files you want to keep to your PC you can include the backup. If you have any issues later on you can copy the backup back to the device and restore the device to it's state prior to any modifications.

The process for installing TWRP is nearly identical for all devices, assuming no bootloader restrictions:

https://www.xda-developers.com/how-to-install-twrp/

Initially it may seem a little daunting but once you've done it a few times you can accomplish it in minutes.

Also, if everything goes as planned but TWRP is missing when you reboot into recovery and the stock recovery is displayed, this is because your installation was overwritten on first boot. After installing TWRP it's a good idea to hold the appropriate key combination for recovery as you 'fastboot reboot' and when TWRP loads, swipe to allow TWRP to modify your system. After that TWRP will remain.

Good luck, it's not as bad as it sounds ;)

All in all I have been very happy with this rom (T-710). Thanks! One main issue I have is that when playing music the sound is distorted. Is it just my device or is it a known issue? Btw. is fingerprint supposed to work now?

I have the T815Y and the fingerprint is working fine for unlock and apps. It may be device specific ...
[Galaxy Tab S2 Android Development] StathisA:
Additional to the above, I do experience some lagging (jittering) in gaming - like the some games lagging every 2-3 seconds but in between lags it is doing 60fps.

Does enyone know what might be the problem? Is there a way to adjust kernel, cpu gpu and other settings to fix that?
[Galaxy Tab S2 Android Development] tzlot:
I have always assumed step 5 would erase the rom and gapps you copied in step 3... I use an SD card to protect them from a full internal wipe... If I'm wrong I'd love to know if there is a safe spot for them internally!
[Galaxy Tab S2 Android Development] ripee:
[MENTION=4990939]tzlot[/MENTION], that is an oversight from too much copying and pasting, I just corrected it.
[Galaxy Tab S2 Android Development] roguetr:
Heh and that shows how well I read things! I'll admit I omitted step 8 because I figured it was covered by step 5 and have only ever used that option in TWRP when wiping an encrypted partition.

Am I missing something? TWRP states it's formatting during step 5 ... Thanks :)

Just back to flashing ROMs after a few years so a little rusty.

Is this a known issue, and is there a way to make it work?

I think (and I could be wrong here as I'm no Dev) this issue on T815 came about around May on the other thread herehttps://xdaforums.com/showpost.php?p=77430952&postcount=281 when Bonuzz added in the fingerprint fixes. What I found was that prior to those fixes going in (ensuring fingerprint works even when tablet is totally asleep) on the May 11 build it sleeps beautifully. The fingerprint did work in that build but only when the screen is dimmed and so he fixed it. From that build onwards I've never found a way to make the tablet reach deep sleep. It's like GPS or something just won't rest. Again, i could be wrong but I wonder if disabling fingerprint entirely could be worth testing.
[Galaxy Tab S2 Android Development] srvoleti:
Actually I am not using fingerprint, but I also don't know how to disable it. Any help is appreciated.

Did you set up any fingerprints at all? I'm going to try removing all of mine and see if it helps. BetterBatteryStats might also help too with isolating what is keeping the tablet awake.

Hello guys,

Can't download the t815 version of the ROM. Does anyone else have the same problem?

Hi [MENTION=6005084]ripee[/MENTION]

First of all - many thanks for keeping our old t810 with your rom ailve and kicking - much appreciated!

Quick question though as i try to work with the static compiled tools- like crytsetup from

https://xdaforums.com/android/software/utils-data-recovery-tools-testdisk-t3709380

It seems the kernel options to support kernel based crypto api are not working or even set.

Can you confirm they are not enabled in the current kernel

and even more interesting - is there a chance to get those compiled in on your next releases ?

Thanks i.a.

I own a T710 operating still on the latest stock ROM. Since I fear, there won't be any further update provided by Samsung I am wondering to move to this unofficial LOS ROM (I am already running LOS/ASOP on various other devices) - also to receive security updates in a timely manner. First of all, thank you to [MENTION=6005084]ripee[/MENTION] for maintaining LOS for our devices! Reading thru this thread, I have still some questions before taking a decision.

The list below refers only to T710 unless mentioned otherwise.

MIC issue (a potential no-go for me): I thought this was already solved in a January build. Correct? Or still an issue for some devices?

sound issue: A report about distorted sound (#367) might have been solved by the 05/19 build ("Tweaked mixers"). Correct?

camera issue: Still listed in the OP but I understood that it was solved in a January build and more "advanced" options are available using e. g. Open Camera. Correct?

battery life (also a potential no-go for me): Seems like this has been resolved in an April build since multiple users (e. g. #390 and #391) report satisfactory battery life for T710. Correct?

unstable WIFI: Is it correct that this appears to be only an issue with some T810?

VPN issue: Multiple users (e. g. #357 and confirmed by others) report that the integrated VPN client keeps giving issues. Correct?

Is it correct that LOS 16.0 will still take a while and it is safe to assume that moving now to 15.1 will not be outdated by tomorrow, right? ;)

Thank you for your help!
[Galaxy Tab S2 Android Development] myfishbear:
Only problems i have is the sound gets too loud and the speakers pop a bit at full volume on my 710. If it put it to 85% its cool (two clicks down from max.) And BT volume is fine.
