[X Style (Pure) Q&A, Help & Troubleshooting] lmulli:
Instead of flashing TWRP as the permanent recovery, just boot to it by putting your phone into Bootloader mode and use the command Fastboot boot twrp.img (replace twrp.img with the filename of your twrp). Then you can install either SuperSU or Magisk as you desire. If using SuperSU, I would recommend using the SuperSUConfig to ensure that it is installed in Systemless > SBIN so that you can then install SUHide in order that you can get the likes of Snapchat working. Magisk of course has this all ready built in so you don't have to mess about flashing extras.

All being well, your device *should* then be able to accept any further OTA's, although I wouldn't hold my breath for any further ones being released.

You might also want to look at Flashfire by the same chap who gave us SuperSU.
[X Style (Pure) Q&A, Help & Troubleshooting] XxperexX:
Thanks a lot! The only problem was that suhide doesn't seem to want to flash. However my root works and so does my snapchat

Edit: Logging out of snapchat wont let me log back in? So is there any way to hide the root?

Edit 2: Nvm. You have to flash SuperSu-SR4 instead of the normal 2.82 one. I was now able to flash suhide and get everything working :)

[Galaxy Tab S Android Development] DarkExistence:
No this will not work on your T805, T700, T705, T805C T807C or whatever you have. Only T800.

Yes there are bugs in this still so please don't make comments saying 'this is buggy' etc as I will have them removed. It is a 'BETA' Only post a bug report if you provide a logcat, and it has to be a major bug not the 'hangouts' issue or any of the other issues I mentioned below.

Flashing this is at totally your own risk and if you damage your device during the process I take no responsibility for it. Please refrain from commenting on this thread with how do I fix my device as I want to make it easier for me to find bug reports.

On first start it will say process system has stopped, just press OK and it wont come up anymore.

Main bugs:

Camera broken.

This thread is purely for people who want to see how the O experience will be on the Tab S.

No ETAs please

Yeay! And I just realize Bluetooth works (but no wifi), and my galaxy s8 I able to share internet (hotspot) via Bluetooth , and it works with my an s7edge (s7 edge was connected to internet only with Bluetooth, data and Wi-Fi disabled. So I will try and I hope it will work on this rom for the tab s :) (of course it's a bit slow like 0.3 mb/s but still works !)

And of course I will try , coast nothing to test and then roll back to nougat , but will by using it for a long time as soon as Wi-Fi works
[Galaxy Tab S Android Development] DarkExistence:
no, t800 only. t700 is still being worked on.
[Galaxy Tab S Android Development] DarkExistence:
awesome! Trying pretty hard to get wifi working, no idea why it isn't. Its exynos5420 brethern, n1awifi and ha3g have wifi working, klimtwifi hasn't had a bootable build yet so unsure if it will work on that. Oh chagall and its wifi... always messes up things
[Galaxy Tab S Android Development] robhug:
Il test "bluetooth Internet " on this tab this afternoon but if it works it would be great because without internet it's not very usable ,but just to test Oreo is already great! I'll let you know if it works :)
[Galaxy Tab S Android Development] Dnorris55:
I got the "setup keeps stopping" errors when I first tried flashing it using Dual Boot Patcher. It wouldn't work installed on extsd or in a Data slot. Finally wiped the Roms I had installed, and installed this on "bare metal". Don't get the setup wizard error.

How's this for ETA; when I get off work tomorrow around 430p, I'm going to take a shower have dinner and proceed back to this channel. It will be at that exact time that I WILL download the new build and install. I will then play with all the new features including WiFi and 1080p then I'm going to hit the sack....then go to sleep :D. J/k! Was able to get posted build working - Pretty sweet! Keep up the good work man no rush, deff appreciate it!
[Galaxy Tab S Android Development] pinsb:
Thanks for this, threw the August build onto a spare 800 I had.

Very impressed and please keep up the great work.

Two questions though....

Location services don't appear to work (Is this related to the shims you mention earlier in the thread?).

At startup I keep getting a google system not working error, which I wait and doesn't reappear, is this common?
[Galaxy Tab S Android Development] DarkExistence:
Yeah theres some GPS errors, and yup, trying to figure out the cause of that error message. Luckily it just happens once though :p
[Galaxy Tab S Android Development] pinsb:
Thanks, I've dropped back to 7.1.2 till location is working, once again great work.

Thanks for your work on the wonderful Tab S!

I do not want to annoy, I would be interested to know how to continue? LOS 16 is coming out soon. LOS Changelog 21.

Does that have an affect on this rom or on the official 14.1?

[Galaxy Tab S Android Development] kdcmert:
Of course
[Galaxy Tab S Android Development] DarkExistence:
Done, thank you :)
[Galaxy Tab S Android Development] Saison2018:
Sorry if it was asked before: Is there any change log available? If yes, where can we find it?

Just want to know if builds are only merging LOS changes or adding any other thing from "Unofficial" development.

Thanks
[Galaxy Tab S Android Development] frittentheke:
It's really awesome that my trusty tablet is kept alive and kicking by running a recent Android, thank you very much for all your work.

Is there a chance to move to LOS 16 at some point, or are there blobs and drivers that would not make that jump (easily) possible?
[Galaxy Tab S Android Development] DarkExistence:
We are hoping too yes, the thing stopping us from pushing more builds atm is the camera. We are trying to get it up and running, and when you have about 6+ different devices to try and get it working on (as its the exynos 5420/22 range) takes a bit of time.

Once we get camera I believe we are going to start work on LOS16.
[Galaxy Tab S Android Development] Tares_PL:
I finally managed to install this beta rom, but unfortunetly, I have some serious video playback issues. All video programs don't work (Twitch, Youtube, MXplayer). I mean the sound is there, but the video is stuck on the first frame. Any ideas, what can I do?
[Galaxy Tab S Android Development] ElsaReyes:
LOS16? Would that still be Android 8 or are you now jumping ahead to Android 9??
[Galaxy Tab S Android Development] frittentheke:
LOS 16 is Android 9, also called "Pie"
[Galaxy Tab S Android Development] Saison2018:
Does someone have an idea / answer?

Thanks
[Galaxy Tab S Android Development] bravomail:
Hey guys, ROM creators! I wanted to shout out why Oreo and higher is important - 24 bit sound! On my newer phone I saw a drastic change in audio quality (GSE7). So I'm very much looking forward to working Oreo or Pie ROM for GTabS! Keep up the good work and Happy New Year!
[Galaxy Tab S Android Development] ElsaReyes:
Um yes, I was just wondering, now that everything but the camera works, I want to update my tablet to LOS 15. But I want to know, the downloadable copy in the first post, is that with everything but the camera working, or is that from when other things weren't working either?
[Galaxy Tab S Android Development] DodgeBullets:
Hi

E read the entire thread and 2 times this question poped but with no answer....

Wich GAPPS to use? i keep getting errors while instaling

Link please

Latest TWRP installed 3.2.3.0
[Galaxy Tab S Android Development] bouwew:
Best to use OpenGAPPS: https://opengapps.org/

Select: ARM - 8.1 - Nano

That worked for me. Feel free to try other variants (pico, micro, etc.)

And then press the red download button. Download the zip to the same directory as where you keep the ROM-zip.

Good luck!
[Galaxy Tab S Android Development] DodgeBullets:
Thanks i managed to get it to work but went back LOS 14 -------> Netflix APP not working. :(
[Galaxy Tab S Android Development] ashyx:
I should imagine it would boot as is, but without sim support.
[Galaxy Tab S Android Development] tayyh89:
I don't suppose it would. Exynos 5420 vs SD 800. Different SoCs.
[Galaxy Tab S Android Development] ashyx:
This is incorrect. T800 and T805 are both Exynos.

Only some T807 models are SD.
[Galaxy Tab S Android Development] tayyh89:
Okay, I wasn't aware of that! Always thought all LTE versions are SD.:o
[Galaxy Tab S Android Development] veggav:
Just installed it and while I can access the files on my external sd card using the built in file manager I can't access those files using anything else.

RetroArch, PerfectViewer, Es File Manager, nothing.

Every folder inside /storage/ or /mnt/media_rw/ is empty.

Is there a way to access the files on external sd card with this OS?

---------- Post added at 12:53 AM ---------- Previous post was at 12:26 AM ----------

I'm experiencing this exact problem.

Can you post the file you used to flash that fixes platform.xml? Tried some from 2016 and none worked.

Also without root this file is not accessible.

EDIT: Followed your google advice and this is the first link:

https://xdaforums.com/showthread.php?t=1458021

Didn't work.

This also, did not work.
[Galaxy Tab S Android Development] wbedard:
I'm pretty busy over the next week or so but I'll try to locate the file I used. However, I'm pretty sure I just edited the file in-place on the device.

While that is certainly true, I'm assuming that it is not an issue for you. If it is, I'm not sure how much I can help you.

End of the development of lineageos 14.1 :(

[Galaxy Tab S Android Development] j1gga84:
Something is wrong with the link.

nevertheless it only means that the official development will stop.

It does not mean that unofficial development will also stop immediately ;)

regards
[Galaxy Tab S Android Development] lurgainn:
Yes, but considering the troubles that arises every when you swap from unofficial to official ROM (mainly the data wipe, so...backup all...restore all...;) ) generally I prefer to wait for official releases: so official 14.1 for our T800 is like dead; official 15.1 is into a future ( far? :crying: ): this is so sad! ;)

Is this ROM still being maintained?
[Galaxy Tab S Android Development] Mrodfr:
The development will restart during next summer we all hope (I'm sure !). The developper is buzy with scool and exams soon ATM. Next summer approach (3 months).
[Galaxy Tab S Android Development] DarkExistence:
Yes this project is still alive, Mrodfr is correct, just finished the first two parts of my final exams so was pretty busy. Rest in June then freedom! :)
[Galaxy Tab S Android Development] pinsb:
While there are some who would want you to focus on this, focus on your college stuff, it's far far far more important and this can wait as we have an almost perfectly functioning build (the 705 and 805 version are quite distorted in phone calls and a couple of other minor niggles, but no showstoppers).

We'll all be grateful if you come back to this at some point in the future and if you could go PIE even better.

Slainte.

When will there be a SM-T700 Version ?
[Galaxy Tab S Android Development] Nukeer9578:
Fix for the memory access problem

Hi,

I'm also using this rom and had the same problem. I was able to fix it by flashing Magisk and installing this module. You still have to root the device but I usually root my devices anyway, so this was no issue for me. Hope it helps!
[Galaxy Tab S Android Development] mac231us:
Pinsb...where is the 705 version (Android 8.1)? Thanks
[Galaxy Tab S Android Development] kaodd:
read the first post !
[Galaxy Tab S Android Development] mac231us:
I already did hence my question... Am not one of those who fast forward to the last page. (maybe need visual aids if am missing something) OP says will not work for 705 700 etc (actually in the 2nd post not the first) but pinsb's post mentioned... Oh well I should say read pinsb's post! Hence my question!
[Galaxy Tab S Android Development] pinsb:
Sorry, I should have been a bit clearer in my previous post.

I meant generic Lineage, rather then specific Lineage 15.1 (8.01).

https://xdaforums.com/galaxy-tab-s/development/rom-lineageos-14-1-sm-t705-t3534828

I too would welcome a jump to 16.1 (Pie) as that would extend this tablet to 2021 for me and as I have eight of them in total (being used for assorted Video, CCTV monitoring, Smart Home management tasks) so would save me upgrading.
[Galaxy Tab S Android Development] Eliar:
Sorry for my bad English :)

If the tablet in the off state is connected to charger, then a screen with a battery appears. There is no animation, neither reacts to any of the buttons, nor to the combination of pressed buttons. When charger is turned off, the screen remains on and still no reacts. I had to disassemble the tablet and disconnect the battery.

Is it just me having such a bug or did someone come across?

Version TWRP can influence on it? TWRP 3.3.0 from here: dl.twrp.me/chagallwifi

I think what to do, try to reflash or try to change the parameters so the system starting when the charging is connected .
[Galaxy Tab S Android Development] ashyx:
You didn't.

Holding power + down until reboot would have been enough.
[Galaxy Tab S Android Development] cookie1338:
Please OP make T700 version too!
[Galaxy Tab S Android Development] airtower:
Just flashed this on my wife's seemingly dead T800, and I have to say I'm quite impressed. She wanted a new Chromebook so this will do nicely for me to replace my T520 which is all but on life support.

Couple issues though:

Google set up had a few hiccups, but the back button got me through it

I had to modify permissions.xml to allow user apps access to the internal SD. External worked fine.

Ambient light sensor doesn't seem to be recognized. No option for adaptive brightness.

Random, but infrequent wifi drop outs

Small horizontal visual artifacts during some transitions, and when screenshotting

Whatever TWRP I was using threw an error 7, but I flashed the latest official and it worked fine

Other than that...

Runs great, no random reboots

Battery seems decent

BT works (at least with the OEM keyboard)

Location services work (edit: only "coarse" location, presumably via wifi. GPS "fine" location services are not working)

Works with magisk 19.3

Keep up the awesome work! I love seeing new life breathed back into these abandoned tablets. Can't wait to see what comes next!
[Galaxy Tab S Android Development] mdc0ffey:
What did you modify in permissions.xml to get access to internal storage?
[Galaxy Tab S Android Development] airtower:
I'll post the file later when I get home. You will need to be rooted however.
[Galaxy Tab S Android Development] airtower:
here you go. its platform.xml not permissions.xml. it goes in /system/etc/permissions
[Galaxy Tab S Android Development] mdc0ffey:
Awesome, thanks for that. Will try it later. Cheers.

Worked a treat. Thanks for that

Has anyone managed to pass SafetyNet in magisk on this rom?

[Galaxy Tab S Android Development] Mrodfr:

[Galaxy Tab S Android Development] hiddeninfrontofyou:
I have been using the Oreo version some months. Really good, but a bit laggy and with some troubles when playing video and/or audio. Maybe I did something wrong when flashing it. In addition, I could not install Netflix. Anyone with the same trouble?.

So, I returned to Nougat, waiting for the new Oreo version.

I am a old (twenty years ago) Linux Sysadmin, and know how difficult is to make all pieces in order to get a functional ROM. Selecting the right kernel compile options and parameters, finding the right setup xml, filesystem, permissions, libs, etc. This is an art, actually.

So, Darkexistence, many thanks for your time.
[Galaxy Tab S Android Development] airtower:
Netflix did not appear in my play store (I believe they whitelist device/OS version combos or something to that effect, and we're not on that list). I was able to sideload, but the app would not run.
[Galaxy Tab S Android Development] mdc0ffey:
Same here. Kept getting restart device error
[Galaxy Tab S Android Development] hiddeninfrontofyou:
It was in mine. I'm from Spain. Maybe the play store contents vary depending on the country?.

In any case, it seems that Netflix doesn't run on that particular version of Lineage, which sounds rare to me.
