New 17.1 builds are on their way. I missed a couple commits in the previous builds, so these should boot.
[Galaxy Tab S2 Android Development] ripee:
It is out of date, but always try the latest twrp with the latest rom, and only downgrade twrp if the latest one doesnt work.
[Galaxy Tab S2 Android Development] Alsnchd:
Build 17.1-20200803 still doesn't work for me on my SM-T810, stuck in bootloop.

I first tried a dirty install and after bootlooping I made a clean install (TWRP 3.3.1.-0) still the same problem.

After that I flashed TWRP 3.4.0-0 and made another attempt at a clean install, also bootlooping.

Force reset just brings me back into recovery. Will give it another chance with the next build, thanks for keeping our devices up to date :)
[Galaxy Tab S2 Android Development] jrodrigues888:
Wiped clean.

Installed the 17.1-20200803 With GAPPS. Does not boot, reboots to TWRP after some time.

Tried clean wipe without GAPPS, same result.

TWRP 3.3.1-0

Would I be able to install this Rom on a t-mobile variant (T817T)? I'm only using the tablet as Wi-Fi only. I believe this T817T has the same processor as the T810 version.
[Galaxy Tab S2 Android Development] mikle_01:
Thanks for answer - but not working for me... :( Could you post a screeenshot with Magisk Modules?
[Galaxy Tab S2 Android Development] halloarno:
Sometimes V4A is disabled. Enable it again: open V4A, press menu in left-upper-corner (three dots), press close, open V4A again.

Or maybe the V4A app found in XDA labs suits you.

(Attached screenshot is from my op6, but I have exact same modules on the tablet).
[Galaxy Tab S2 Android Development] chigo58:
Loaded on 710 with pico x86 gapps. - and running smoothly. twrp installation was a pain as usb mtp didnt work with 3.2.3-0 so installed prev. version, loaded zips on internal storage, upgragded twrp, wiped all, and the rest is history. can confirm fingerprint on lockscreen doesnt work - other than that the gamma setting seems off as the colors look faded, the but the rom works much better than stock - TY sir!

Changelog

Build 0108 for all variants

* T715 & T815: GPS now loads libsensor. This should fix the deep sleep issue, if it isn't deeper than this ;)

* More work on the SD card.

* Enabled the exFAT driver. If this doesn't add compatibility, then it's at least the first step.

* Synced with LineageOS sources
[Galaxy Tab S2 Android Development] toby184:
hi ripee, thanks for the latest build! corrupted sd card issue still exists. to replicate format sd as internal, then a) select move later, sd card status shows corrupted 'not enough space' popup, issue exists after restart b) selecting move now shows same issue.
[Galaxy Tab S2 Android Development] ripee:
Did you try what I wrote in a previous post?
[Galaxy Tab S2 Android Development] toby184:
Followed these instructions also on the latest build 0108. After formatting as internal (appears to terminate at 40%) then goes to move data menu, at which point i restart. Upon startup sd shows as corrupted.
[Galaxy Tab S2 Android Development] ripee:
Can you please capture a logcat from the moment you begin formatting to when it terminates at 40%. This may be related to encryption of adoptable storage.
[Galaxy Tab S2 Android Development] srvoleti:
Can't find today's build for 815. Please help.

Edit:Just found it, may be delayed in uploading.
[Galaxy Tab S2 Android Development] kabelgleichung:
exFAT works, thanks!

But unfortunately, my T715 still does not enter deep sleep. If you need any debug-information don't hesitate to ask!
[Galaxy Tab S2 Android Development] ripee:
Changelog

2nd build 0108 for all variants

* In addition to the above changelog, I set the appropriate PRODUCT_AAPT_PREBUILT_DPI. This should help apps make proper use of the dimensions of the screen. This is especially geared toward the AOSP camera app on T710 and T715/Y.

* Synced with LineageOS sources
[Galaxy Tab S2 Android Development] Meakii:
Much appreciated trying to sort this issue for us. Will give it a try and report back :good:
[Galaxy Tab S2 Android Development] amau05:
Hello I've just installed the last version on a t810 and it went fine there is just one issue, the fingerprint reader. I can add fingerprints without issue but when I try to unlock the tablet it doesn't react, I'm forced to use the pin code. I don't know if it has any influence but I used the pico version of Gapps.
[Galaxy Tab S2 Android Development] dombo1970:
Just tried it with my T810, fingerprint reader is working as it should, no need to enter the pin code. (am using the micro version of Gapps btw)
[Galaxy Tab S2 Android Development] C0BRA01:
It's been hit or miss for me. Sometimes it works, and sometimes it doesn't.
[Galaxy Tab S2 Android Development] amau05:
Edit : Withdrew what I said it works with Gapps micro... Will try Gapps nano next to see if it works because I really don't want Google craps...

Edit 2 : Gapps nano doesn't work either so I guess there is something in the micro one that's needed...
[Galaxy Tab S2 Android Development] tripLr:
Glad you found that

---------- Post added at 09:39 PM ---------- Previous post was at 09:38 PM ----------

Use pico to set up. Then download what apps you need.
[Galaxy Tab S2 Android Development] chigo58:
Loaded on T710 and fingerprint access after lock works :)
[Galaxy Tab S2 Android Development] Meakii:
T815 still not making deep sleep (sadly) on latest build have attached screenshots from BBS and Amplify
[Galaxy Tab S2 Android Development] amau05:
I withdrew what I said again... I don't understand it... After rebooting the tablet you need to enter the pin code the first time then you can use fingerprints, it works but only in the beginning after a few minutes the reader doesn't detect anything anymore. I tough it could be my task manager auto-kill at startup so I disabled it, didn't change anything. After I tough it could be because the micro package contain the pixel launcher so it could be that trebuchet launcher did not handle the reader so I put the pixel launcher as main launcher but it didn't change anything...

I'm out of idea and I don't wan't to let my tablet unlocked and I don't like the other options... Somebody have an idea?

T810 0803 veriosn fails to boot

Update: Flash the 0803 version. It fails to boot again
[Galaxy Tab S2 Android Development] Davivigo:
I've flashed 0803 version. Clean installation on my T715 with TWRP 3.4. Working nice at this moment, very smooth. Thanks Ripee, great job as usual !

Hello ,

There : "https://twrp.me/Devices/"
[Galaxy Tab S2 Android Development] JoshReuben:
It's been awhile.. Can the updated twrp image be flashed to the recovery partition in old twrp, or does it need to be pushed with Odin?
[Galaxy Tab S2 Android Development] Davivigo:
Here:

http://twrp.me/site/update/2020/06/24/twrp-3.4.0-0-released.html

You hace to go to "devices" and select the right model.
[Galaxy Tab S2 Android Development] bmwdroid:
All new versions can be flashed when they are .img using the old TWRP.

Gotta select "image" not "zip" in TWRP and flash to "recovery" not "boot".

Afterwards boot into new version directly.

.tar to be flashed using Odin.

Depends on what you downloaded.
[Galaxy Tab S2 Android Development] dmarshal17:
Same for me and my t810. 16 works fine, 17.1 won't boot. Updated twrp to 3.4.0.0 same results. Appears to flash with no problems.
[Galaxy Tab S2 Android Development] srvoleti:
Just flashed the latest 03082020 version. Clean installation on my T815 with TWRP 3.4. Working fine and buttery smooth! Thank you [MENTION=6005084]ripee[/MENTION] for the excellent work!!

Has anyone tried upgrading via dirty flash?
[Galaxy Tab S2 Android Development] dombo1970:
I tried it the dirty way, but failed. T810.
[Galaxy Tab S2 Android Development] Davivigo:
Last night my T715 begun to crash sometimes and have to hard boot. If I wait some minutes then it starts on TWRP 3.4 recovery. Could it be the problem, maybe?
[Galaxy Tab S2 Android Development] MrBlubke:
samsung tab S2 t810

installed lineage-17.1-20200803-UNOFFICIAL-gts210wifi.zip + open gapps 10.0 mini 20200805

stuck at samsung logo

suggestions welcome

---------- Post added at 10:43 PM ---------- Previous post was at 09:51 PM ----------

well I went even further in the dark... couldn't even revert to 16.0 on top of that in a desperate attempt I flashed a wrong twrp version, and my tablet appeared dead... no access to recovery no access to rom or data...

I dug up ODIN and reflashed TWRP 3.3.1.0 since I figure when the old version TWRP can't install the newer roms the same might be true for the newer TWRP not being able to install los 16.0 and I'm back on LOS16.0 now

so now you know TWRP 3.4 can't install los16 ...

I still want to give 17.1 another try, but not now...
[Galaxy Tab S2 Android Development] falconetab:
T710 - everything is working (except buttons lights) with v16 but impossible with 17.1 - tried everything i could

Thanx a lot for keeping these devices alive !
[Galaxy Tab S2 Android Development] wwmhf:
Moving to 17.1 on this old T710 is exciting! I appreciate rippe's contributions. Many thanks even though I could not get it installed yet.
[Galaxy Tab S2 Android Development] sal82:
Try unchecking "install TWRP as a system app" when installing. I have the same tablet and had the same problem with pie.
[Galaxy Tab S2 Android Development] MrBlubke:
just pressing the "do not install" instead of swiping isn't enough? I'll have to try that again then...
[Galaxy Tab S2 Android Development] MrBlubke:
well apparently that wasn't it...

no luck here... you said you have the same tablet? t810?

can you share the exact steps you did? maybe we missed something...
[Galaxy Tab S2 Android Development] Davivigo:
Finally I had to flash 16.0 again. 17.1 had too many crashes and I try to know if were caused by TWRP 3.4. But 16.0 works fine. I hope this problems will be solved, but great job anyway!
[Galaxy Tab S2 Android Development] snsnse:
I just upgraded from the latest LOS 16 by dirty-flashing 17.1 (20200803) and opengapps 10 pico on a T815. All went fine and no problems so far. Since dirty-flashing didn't seem to work for most people, I thought I'd share what I did:

* reboot into recovery

* wipe dalvik, cache

* upgrade TWRP to 3.4 using .img and rebooting into recovery after flash

* reboot system, then shut down

* reboot into recovery

* wipe dalvik, cache

* install LOS 17.1 and latest opengapps 10 pico

* wipe dalvik, cache

* reboot system, do NOT install TWRP as a system app (whenever you're prompted)

* boot process finished without problems (i.e. no boot loops, no re-booting into recovery, etc)

The excessive wiping of dalvik/cache is most likely unnecessary. Although there's nothing exceptional I did, this worked for me. No guarantees, though.

So many thanks to ripee for all his great work, on this ROM and otherwise!

HTH
[Galaxy Tab S2 Android Development] syd-3:
on my SM-T810, I try a lot of thinks with 200803, like dirty flash, clean install, wipe all, install without or with pico, twrp 3.4...

nothing works, stay on android black screen, or boot in twrp in some time, no lineage animation.

came back on LOS16 with restore.

waiting for other version of ripee rom to flash...
[Galaxy Tab S2 Android Development] MrBlubke:
yeah, same here on T810

also checked if ripee had some custom TWRP like he has for some other devices, and the gts210vewifi.zip doesn't work (name seemed rather similar enough, but apparently still some other device)

also have to restore 3.3.1 to be able to install 16.0 again TWRP 3.4.0.0 trows error 7 when trying to flash los 16.0
[Galaxy Tab S2 Android Development] metterschling:
After flashing TWRP and rebooting to TWRP 3.4.0, wipe System, Cache and Dalvik, then reboot to recovery once more. After that flashing might work.. This extra wipe and boot cycle got TWRP 3.4.0 working for me and many others on another device (Grouper) where we had the "error 7" condition as well.
[Galaxy Tab S2 Android Development] MrBlubke:
well this at least let me install 16.0 using TWRP 3.4.0, so thanks for that... no luck for 17.1 yet though...
[Galaxy Tab S2 Android Development] snsnse:
With respect to the "black screen" situation I have to say I'm seeing this too on my T815 when trying to reboot. After the S2 logo the boot process would not start and the tablet screen stays black.

Going into download mode (power - volume down - home) and then cancelling by pushing "volume down" fixes this and makes the tablet reboot normally. Curiously, I usually have to do this twice for it to reboot successfully (three times on one occasion). Looks a bit like a race condition to me, whether TWRP is to blame I'm not sure. After the system reboots everything is fine, no issues with the ROM per se.
[Galaxy Tab S2 Android Development] MrBlubke:
at least those get past the Samsung tab S2 screen... mine is just stuck there... although oddly enough, after about 10 seconds when connected to PC I get the usb connection sound.... which I wouldn't expect when being totally locked up, right?
[Galaxy Tab S2 Android Development] bmwdroid:
But you can access dwnld mode and reflash or can't you?
[Galaxy Tab S2 Android Development] snsnse:
MHL/HDMI connection causes UI freeze on T815

With the latest LOS 16 I could use the MHL interface for HDMI connections on my T815. With 17.1 the screen freezes whenever I connect an HDMI device (TV in this case). The UI freeze stops as soon as I disconnect HDMI, so it's not causing the device to crash. Turning on "Disable HW overlays" in developer options fixes this and the screen is mirrored to HDMI as expected. But the UI response becomes more sluggish.
[Galaxy Tab S2 Android Development] MrBlubke:
I can still access TWRP if that's what you meant... so yes I can revert to 16.0...

so far 17.1 is a no go... unfortunately I will try again with next builds though
[Galaxy Tab S2 Android Development] ripee:
gts210vewifi is a completely different device! T810 is gts210wifi!

Follow snsnse's steps and let us know.

"ve" standes for Value Edition, which is Samsung's fancy way of calling the 2nd edition, in this case the following model year, 2016, which has a different chipset than the 2015 model year.
[Galaxy Tab S2 Android Development] MrBlubke:
do you have a custom twrp 3.4.0.0 for gts210wifi cause I couldn't find it... with the regular 3.4.0.0 (from twrp site) let's me install the rom, but stuck on samsung logo, but like I stated after a while (when connected to pc) I get the connect sound, which I assume I wouldn't get if it really locked up at that screen, right? am I right in assuming that?

so is this what you were refering to when you say to try the steps snsne suggest?

or is it the post before that... cause the post before that I did without success unfortunately... I did however not try the going to download mode and canceling that yet... I could give that another shot... I'll report back...

report: no luck with the download mode workaround either... it just goes back to the TAB S2 screen...
[Galaxy Tab S2 Android Development] numbfall:
Hi all,

T710 (gts28wifi)

no luck with the los 17.1 and gapps 10 and twrp 3.4

really excited for future though. thanks ripee for the excellent work sir.

[Galaxy Tab S2 Android Development] MrBlubke:
that was the one I'm already having... I know about TWRP.ME I just figured there might be an adjusted one for this situation...
[Galaxy Tab S2 Android Development] aboulafia1901:
Sometimes i reinstall stock rom (rom in 3 or 4 files

not the tar

), before installing new rom custom .I know in the past ,this solution resolved the "error 7" for me and since then I do it every time I install a new rom like here where we go from android 9 to android 10. Perhaps it is the solution for you .
[Galaxy Tab S2 Android Development] kabelgleichung:
I am experiencing problems on my SM-T715 with at least the two latest versions of 16.0 (20200714 and 20200810). When using standard applications (browser, mail, youtube), the tablet starts lagging exremly and then the screen freezes while staying on. I cannot use any of the hardware keys and cannot switch the screen off. I already tried a clean install - same problem. To exclude a hardware failure, I went back to a backup of stock rom, where the problem does not exist with the same app configuration. Any ideas how to debug this?
[Galaxy Tab S2 Android Development] MrBlubke:
thank you for trying to help, but the error 7 with TWRP 3.4.0.0 has been resolved by taking the steps mentioned earlier in this thread, and occurred only when trying to install los16.0 with TWRP 3.4.0.0.

I have just updated to August 10th build of los 16.0 with success... installation of los 17.1 doesn't give any errors, it's just sits at the Samsung Tab S2 screen for ever...

on that matter... is there anyone at all with a t810 that has a success story with 17.1?
[Galaxy Tab S2 Android Development] kabelgleichung:
I tried the AOSP Extended ROM ( https://xdaforums.com/tab-s2/development/rom-aospextended-rom-v6-7-t3979381 ) and encounter the same problem. As I supposed it might be a hardware issue, I went back to the old stock ROM, where the problem does not occur, so faulty hardware might not be the issue.

I think the problem occurs during more or less heavy GPU usage (video playing or scrolling in maps). Any ideas how to further investigate on this?
[Galaxy Tab S2 Android Development] MrBlubke:
does rhe phone heat up at that time? does it feel hot?
[Galaxy Tab S2 Android Development] kabelgleichung:
The sensor exynos-therm is at ~55°C, the device does not feel to hot. I am going to investigate further on that.
[Galaxy Tab S2 Android Development] dombo1970:
On my T810 the latest LOS16 (20200816) has a strange behavior. It's loosing the well-known wifi-network, when trying to reconnect it's turning wifi off completely. Can't reconnect. at all, the wifi-network is not visible on the Tablet (but it's avaible and working, I can see it on the mobile phone).
[Galaxy Tab S2 Android Development] yoshkapundrick:
I tried 8/16 on my T810. I connected to a hidden network and an open network with no problem. Network detection sees numerous active and open networks. Used settings to connect and disconnect with no apparent problem.

I did not connect for an extended period of time so I did not determine if dropping of signal became apparent after longer connection.
[Galaxy Tab S2 Android Development] dombo1970:
Working now, don't know what happened.
[Galaxy Tab S2 Android Development] Davivigo:
I've installed again the 17.1 version (0803 build) on my T715 (gts28ltexx) I've back TWRP to 3.3.1.0, but without istalling TWRP App. Clean installation. Running ok since then, two days ago. The only bug i've noticed is the GPS (it doesn't work).

I will continue to test it.
[Galaxy Tab S2 Android Development] MrBlubke:
latest 16.0.seems to work... I'm very happy with your work, but of course still looking forward to next 17.1 build to see if ot makes any difference... any insight in what's basically different between the boot process of both? what might cause the 17.1 not to boot into the installation?
[Galaxy Tab S2 Android Development] ultrax1887:
How can i go back to Stock Rom? I have no Backup...
[Galaxy Tab S2 Android Development] bmwdroid:
Download stock for your region in sammobile.com or samfrew.com or use samfirm tool.

Then flash it with Odin.
[Galaxy Tab S2 Android Development] jenom:
I can confirm that for the T810 the 17.1 image does hang on the Samsung logo and with later tries hangs and then reboots into TWRP. I have tried with TWRP 3.3.1 and 3.4 as well as with and without SD card present, dirty and clean flash.
[Galaxy Tab S2 Android Development] MrBlubke:
Yes, that perfectly reflects my experience...
[Galaxy Tab S2 Android Development] blackspp:
That's why I'm still on the latest 16 release
[Galaxy Tab S2 Android Development] MrBlubke:
same here... I'm still eager to move to 17.1 when a new build comes... I'm on los 17.1 on all my other devices (except my daughter's NVIDIA Shield which is even still on 15.1) so would be nice...

Lineage imho still is the best Android experience for me ?
[Galaxy Tab S2 Android Development] blackspp:
Actually I more or less decided the S2 has to go. It's too slow for many modern websites, WiFi receiver is kinda weak. In my garden I hardly get half a bar while on my Mate 20 pro I have all 5. Battery is sort of OK after I replaced it.

But I'm looking for something that will last another 5 years again. Maybe the new Tab S7 plus. Al tough it's **** expensive. Maybe the 6 is better, al I do is surfing anyway haha
[Galaxy Tab S2 Android Development] kabelgleichung:
Can you check the intervals at which connection is lost?

I did some investigations: I loose my connection exactly every 600 seconds, which is a common interval for WPA group rekeying. There might be a but in this ROM when handling this rekeying.
[Galaxy Tab S2 Android Development] dombo1970:
I don't have this problem anymore, guess it was something with the wifi router.

With display on the wifi is not disconnecting.
[Galaxy Tab S2 Android Development] alias4ever:
How does this (16) compare to 17.1. I have 17.1 on my T710 now but the standby battery is not the greatest. :( This have any better battery? Thanks for all the hard work on both ROMs! :D

I dirty-flashed the 20200902 17.1 build over the previous 17.1 build on a T815/gts210ltexx (opengapps pico). First reboot after the installation went without issues.

The next reboot resulted in the infamous black screen after the S2 logo, and I had to repeat the procedure described here about 5-6 times before the tablet would reboot normally again. But ultimately this worked for me so far.

Otherwise, no issues with the ROM.
