Sometimes you find stock ROMs consisting of only one file to flash in AP slot of Odin while I prefer those ROM versions which consist of 4 or 5 separat files (AP, BL, CP, CSC).

For wifi Tablets CP may be missing.

Oo,i have thats file,n i flashing my tab but still need nv_data.bin ,to restore my imei.

My device is t815y ,i need help anybody to send me nv_data.bin inside folder efs 🤕🤕🤕
[Galaxy Tab S2 Android Development] bmwdroid:

Hi,

I've also got issues with battery and Chrome hangups with 20211208. Can you get me a link for 20211103 on the T815 ? Thank you in advance
[Galaxy Tab S2 Android Development] aboulafia1901:
Hello ,

I send you a mail .
[Galaxy Tab S2 Android Development] Older Fogie:
I need to ask, too:

Dear @bmwdroid could you give me a link to the 20211103 gts210wifi build? Thank you!

Hi Guys! Any chance to get 20211103 gts28ltexx build? Would appreciate it very much. Thanks in advance!
[Galaxy Tab S2 Android Development] MrBlubke:
It would be sweet if you could add me to that group 😚😅
[Galaxy Tab S2 Android Development] bmwdroid:
Sorry, wasn't possible.

Had to start a new one for us two.
[Galaxy Tab S2 Android Development] atatdotdot:
Hi @bmwdroid, could you send me a link to this known-good build too, please?

Also, pardon my ignorance, but is there a need to use specific gapps builds or will the latest be fine? And can you confirm that gts210wifi is arm and not arm64?
[Galaxy Tab S2 Android Development] seanw712:
@bmwdroid sorry for the bother, but I'd be very happy to get the link to this build too!

Thank you :)
[Galaxy Tab S2 Android Development] bmwdroid:
Got PM.

After having to often problems with Opengapps I've switched to Bitgapps.

It has Octacore CPU and ARM64 should be correct.
[Galaxy Tab S2 Android Development] atatdotdot:
Sorry, do you mean that you've sent me a PM? I don't see it. Sorry if I'm being stupid, I haven't used this forum before!

I'm not sure any longer.

Just looked up in PhoneInfo SAM and saw Kernel Version is 3.10.9+ 32bit.
[Galaxy Tab S2 Android Development] aboulafia1901:
Hello ,

I think also it is arm .Arm64 are for T713-T719-T813-T819 .@ripee treated the subject separately here .
[Galaxy Tab S2 Android Development] bmwdroid:
Afaik they have Snapdragon therefore need a different ROM anyhow.

These here have Exynos.

Both have 64b CPU but I doubt that a 32bit kernel would support 64b Gapps.

[Galaxy Tab S2 Android Development] simon-edwards:
Appologies for the double posting. Not sure how to delete a post.
[Galaxy Tab S2 Android Development] metterschling:
Sure, PM sent.

It looks like development has ceased, unfortunately. As we're getting into severe security exposures, I've started looking for a new device. For my uses cases the SGT hardware capabilities are still more than enough so from a sustainability perspective it's a bit of a pity but this is how's it is. Thanks to the great work of ripee and ananjaser1211 the tablet already greatly extended its life with recent ROMs.

Hello )

I got this device

T710x / Android 5.0.2, in a completely stock variant

it comes with 16gb ROM and no 3g support

the question is - which ROM should I flash in order to get as newest and stable as possible Android version (would be ok even if it would be Android 8.0 doesn't matter too much), with everything working correctly (wifi / camera / etc) ?

and what are the exact things I have to do in order to get everything right ?

would kindly appreciate your help )

thanks in advance

Would you please so kind and tell me why that image (lineage-18.1-20211103-UNOFFICIAL-gts210wifi) is such a secret ?

What is special about that build ?

Just wanted to give it a try on my T810, because the current ROM is ~ 2 years old.

Hello ,

I did it with pleasure but considering the message that @bmdroid received (see post #2,362), I see myself obliged not to do it anymore. Especially since @ripee is no longer involved in this thread, we don't know his position on this. .Reading the conversation thread ,I still think that the latest build for the sm-t815 poses less problems than for the sm-t810 .For info ,personally, I'm currently using a Resurrection Remix ,which is discontinued, also from @ripee, under android 10 which allows me to replace the gapps by the MicroG-Gapps module under Magisk. I'm sorry.
[Galaxy Tab S2 Android Development] dcaffeine8d:
I started using this build now - lineage-18.1-20220410-UNOFFICIAL-gts210wifi.zip. This is from this thread - https://xdaforums.com/t/unofficial-rom-beta-lineageos-18-1-for-sm-t810-april-10-2022.4430349/.

It has the latest Android Security updates and will be continually updated. Installed this and no issues so far from what I had with the lineage-18.1-20211208-UNOFFICIAL-gts210wifi.zip build.

I don't see the wifi issue anymore when it goes to deep sleep (I think @retiredtab fixed it in his build. Plus Netflix and the Plex app is now working. Did not install Magisk this time. Best thing is that it's selinux enforcing so Playstore has it as Device Certified!
[Galaxy Tab S2 Android Development] computersalat:
Hi,

what is the problem wth that message ?

I do not understand why this image is such a secret.

I used that image, too and no problems so far. Even not with WiFi.

BTW all latest builds from @ripee are still accessible via the first and second post, except this `magic` image not.

Thanks to all
[Galaxy Tab S2 Android Development] dcaffeine8d:
That's the word - "magic"! It vanished into thin air I guess. :sneaky: Anyway, I'm in that time of the year where I'm rolling ROMs just for the fun of it when I'm bored.
[Galaxy Tab S2 Android Development] aboulafia1901:
I don't really know but I think it's normal to ask for @ripee's agreement, but @ripee doesn't intervene anymore. I'll ask him and see if he'll answer.
[Galaxy Tab S2 Android Development] ripee:
There is no secret with this build, I may have it somewhere on the build server I use but I can't promise that it's still available.
[Galaxy Tab S2 Android Development] aboulafia1901:
I sent you my link :)
[Galaxy Tab S2 Android Development] yoshkapundrick:

Hi @ripee

You've got a PM 🙏
[Galaxy Tab S2 Android Development] bmwdroid:
For T810 owners ONLY:

there's a thread with a new ROM by @retiredtab and his crew which I switched to.

ROM seems to be stable (although still beta) and WiFi connecting whenever turned on.
[Galaxy Tab S2 Android Development] lpedia:
Hi, @bmwdroid. Glad you're finding the ROM stable!

There's a similar @retiredtab thread for the SM-T710: https://xdaforums.com/t/unofficial-rom-beta-lineageos-18-1-for-sm-t710-april-11-2022.4430339/. This ROM has been very stable on my T710 for months now. I invite other T710 owners to give it a try - and let us know how it goes for you. 🙂

Please note that both of these threads are ONLY for the named model.

Hi, I have a SM T-715 (gts28ltexx). When installing lineage-18.1. from the first post of this forum, the sim card (mobile internet) does not work.

I tried to find a solution on this forum, but I didn't find anything. Does anyone know how to solve this problem?

Alternatively, does anyone have an older version of lineageOS? E.g. 17.1 for Samsung Galaxy tab s2 8.0 LTE (gts28ltexx) SM T-715.

Thanks

is there any guide for this?
[Galaxy Tab S2 Android Development] Michiel0912:
The internet is full of guides.
[Galaxy Tab S2 Android Development] ripee:
TWRP is a separate product, so it has its own thread ;) I linked the bootloader and modem there as well since it's also rom-independent, and although not really related with TWRP, still something worth considering updating while you're updating TWRP.

Edit: moved the bootloader_modem instructions to the TWRP thread.

one more thing.. I already flash the rom n gapps..

Just to provide some feedback: per app battery optimization for the respective apps is not solving the above mentioned problem with Wi-Fi disconnecting while those apps are still active/streaming. As I mentioned, LOS 14.1 behaved differently for me, other thoughts on this are most welcome.

So is been a looong time since I have installed anything like this. Everything seems to have went well but root isn't working. 815 version, any ideas why? Thanks to the dev!!

I assumed you flashed root

https://download.lineageos.org/extras
[Galaxy Tab S2 Android Development] republicano:
samsung 715y

So i flashed this rom with pico.gapps

i think these issues have been noted or if its related to RIL

i noticed the fingerprint sensor does not need to be pressed to unlock as you do in stock rom so the sensor was on the whole time so i remove the fingerprint and went back to pin, disabled body sensors with google play.

i was having gpsd and vfsspi wakelocks, must be related to RIL
[Galaxy Tab S2 Android Development] samw52000:
Just to confirm that I can still dirty flash and clean temp/dalvik to flash different version updates.

Also is OS 16 on the horizon? I've seen a single built thus far that I was able to flash but ended up giving me lots of grieves... and errors. This particular version runs smoothly on my 710... real happy about finally getting some realtime security updates.

Hi all, this ROM has been great on my 815 but I'm wondering if anyone has any battery life tips? I understand there's a deep sleep issue but is there any way to force this state with 3rd party apps or anything?

[Galaxy Tab S2 Android Development] dombo1970:
How official or published is the LineAge v16 which can be found in the download folder?

Dirty flashing at least wasn't successful.

The screen is 90° rotated.
[Galaxy Tab S2 Android Development] jimcnt:
Screen Rotated

Same as above. Installed ROM as per norm. When i arrived at the pattern enter screen image was rotated 90 degrees. The touch screen appeared to be normal. Was able to boot back into recovery and am installing the feb rom.
[Galaxy Tab S2 Android Development] ripee:
Can you please explain in detail what you are referring to as the image being rotated 90 degrees? As an example, what happens if you tap on the top left corner of the screen? Which other part of the screen acknowledges that you touched it, since we know it's not the part of the screen that should acknowledge the touch, which is below your finger.
[Galaxy Tab S2 Android Development] jimcnt:
Screen Rotated

Sorry. I have tried to install the Feb release and am having issues so i can't say exactly what is happening.

When the March release booted and the enter pattern screen was up, it was rotated 90 degrees left. If you turned the device it would follow, but when you went to enter the pattern it would respond as if it was not rotated. I was able to guess where to press to perform a power off. Then booted into TWRP and tried to install the Feb release. This for some reason hung (would go through the loading and then reboot.) I am currently doing a full wipe and re-install of the Feb release. This has completed and i am now restoring the apps.
[Galaxy Tab S2 Android Development] gege0202:
hi, the last version still have idle drain for t815 lte?

thanks for answers
[Galaxy Tab S2 Android Development] ripee:
Build 20211103 is back up for all 4 variants!

In response to popular demand, I have dug up this build in the archives of the build server I use, and I uploaded all 4 builds earlier today into their respective folders as linked in the OP.

In regard to what bmwdroid has been doing with my builds, I do not support their being posted elsewhere, however I know of course that I have no control over what anyone does with my builds. I can only appreciate the sentiment, but only so far as it does not violate any XDA rules.

As for the newer builds, as they are less stable, I will be removing them at the earliest convenience.
[Galaxy Tab S2 Android Development] jenda_13:
Thanks, but it looks like build 20211103 for gts28ltexx has the same problem as the newer builds i.e. non-functioning mobile internet.

Anyway thanks for your time.

[Galaxy Tab S2 Android Development] shalannn:
can you give me a link ??
[Galaxy Tab S2 Android Development] simon-edwards:
Thanks for supplyting the older build @ripee.

Will you be doing any more up to date builds with the S2 WiFi blobs back in place?

Are there any instructions for building these ROMs myself ? I have a 715Y and would like to see if I can get the LTE unit working. I also like to set SELinux enforcing by default. I thought I found a post with instructions whilst idly browsing a while back, but now I can't seem to find it.
[Galaxy Tab S2 Android Development] metterschling:
Maybe this one: https://wiki.lineageos.org/devices/gts210ltexx/build - for the 10inch one but most likely easy to adopt.

I had similar thoughts this weekend 😉. The great recent work by @retiredtab for the WiFi variants is truely inspiring. Started trying to build using the Container-based build environment.

Separately I patched libsec-ril.so with patchelf 0.9 myself (see attachment) to explore if using that one will fix the LOS18.1 RIL issues. Based on the vendor blobs from here. Unfortunately I did not find the time to test yet...the T715 is my primary device.
[Galaxy Tab S2 Android Development] pilspeda:
Did a clean install with the latest build and my wifi keeps dropping (irregularly).

Any idea what I can do ?
[Galaxy Tab S2 Android Development] simon-edwards:
Which exact build did you use?
[Galaxy Tab S2 Android Development] pilspeda:
lineage-18.1-20211103-UNOFFICIAL-gts210wifi.zip

Downloaded from the link posted in the opening post (https://drive.google.com/drive/folders/1lhTriEjKRoDosIQHwACcTzH282jeQ0ag)
[Galaxy Tab S2 Android Development] simon-edwards:
Assuming that I only needed to replace these two in the system area ...

/system/lib/libsec-ril.so

/system/vendor/lib/libsec-ril.so

... then I see no difference in SIM recognition after an initial re-boot.

After wiping cache and dalvik and re-booting, there was still no change in behaviour.

There are a dozen or so copies of those two under various vendor directories (I feel its strange they are not symlinks. Does android not support symlinks in its filesystem?) and I didn't try to replace all of them.
[Galaxy Tab S2 Android Development] metterschling:
You did exactly what I had in mind, thank you for trying. It'd be nice if you could check your logcat if it still contains the libsec-ril.so dlopen errors as observed here or if using patchelf 0.9 as recommended by ananjaser1211 at least fixed that issue.

This commit provides the context, there only the two above locations are used.

If you perform a

find /system -type l

you'll find a bunch of symlinks on your Android device. I've got no idea why these lib copies aren't symlinked.

Hello ,

I have a Tab S2 is a SM-T810 WiFi

I have TWRP twrp_3.1.0-1_sm-t810_13317

I cannot get any newer version of TWRP to boot when holding down PWR+VOL UP+HOME buttons , it just stays on the samsung loading screen and if I hold them long enough the screen just turns off

I was running 5.0.2 android version on the device itself (official version)

Please help!
