[Galaxy Tab S Android Development] jays note 2:
That's a good question,....and alot of Users here will all have their own opinions.

The question you have too ask yourself is.... what do I want too archive, the original Tab s 8.4 is getting on in age and unfortunately there aren't many Customs Roms available because of it.

I'm guessing the Tab S is running Stock 5.1.1 lollipop (Yack) lolz! I know that feeling.... Honestly I can't think of any Roms that aren't closed or not being Updated apart from these 2 .....The latest Lineage here and CR Droid

Both have there Pros & Cons and you'll need to read thru both OPs to get a better understanding of what too expect.

I run both Lineage and CR Droid on both my T705y tablets, and even though they run as they should there are bugs that...well are too be expected with a OS that's not really designed to run on older hardware.

My only suggestion is too look through the Tab S development page, Stay away from the older Roms as their links are probably dead. There maybe a couple AOSP Roms that will give you that Google pixel feeling but apart from that our options are slim to none.

Sorry I couldn't be of more help to you, Good luck!!! Remember if you need help....Your fellow XDA users no doubt will help you out.

Frank your tha Boss , thanks for all your amazing roms !

Hello, does anyone know if the SELinux permissive issue is being looked at? Are there any source files such that someone could pick this up and fix the ROM on that front?
[Galaxy Tab S Android Development] bluess57:
Yes the source is available

LineageOS

A free and open-source operating system for various devices, based on the Android mobile platform. This is a mirror of https://review.lineageos.org/ - LineageOS

github.com

https://Github.com/exynos5420

Building the ROM is not a problem for anyone with Linux and some disk space

[Galaxy Tab S Android Development] pawelluk:
Hello,

I have a SM-T800, with latest 3.6.2_9 TWRP and Lineageos 17.1 (20220619) but not rooted.

Could anyone suggest version of Magisk(zip) that would work through TWRP to root the device? What version of Magisk APK would you then recommend for it?

Thank you!
[Galaxy Tab S Android Development] pucci2:
Excellent rom apart from the non-existent data problem, too bad for such sporadic updates and you can not update them directly by downloading them from the android system
[Galaxy Tab S Android Development] LR7875:
You have a snapdragon variant, only 4 cores.

BTW, Android 5 is kaput in terms of app support, you can only install apps of a version a few years ago.

Can you elaborate your display resolution problem? Is there any problem except the YouTubes being a little bit less sharp and vibrant?
[Galaxy Tab S Android Development] hossputer7:
ok thx

it have zoom in 720p or other resulation in video online . when it zoom i cant see video in my screan in original dpi and my dpi its bad and zoom very badly in screan video . i see half screan besacse my screan hase big zoom .

but its not all video but it hase and very bad .

i can go in 1080 or in 480p and test it . it has not zoom . meybe ok meybe not.

[Galaxy Tab S Android Development] Concept48:
Not at all , see if a updated TWRP was released for your model if not try to flash the rom on the TWRP you are using for 14.1 , please report back if it worked for you , remember installing GApps will slow down the device , to overcome that problem , install Aurorastore 4.11 and use that as main source for applications , good luck.
[Galaxy Tab S Android Development] Concept48:
Remember , this is not a samsung ROm and stuff as dex etc are not available - find alternative was to do your thing on Android 10 , cables work to
[Galaxy Tab S Android Development] pucci2:
Why do you say that gapps slows down the device? Is AURORASTORE secure for the account? Can Aurorastore also be installed on Huawei devices without playstores and install regularly purchased applications.
[Galaxy Tab S Android Development] LR7875:
Yep aurora store works on Huawei, but I am not sure if it can install paid apps or not. It does not need to login account
[Galaxy Tab S Android Development] keshayen:
hi all, i have a SM-T805 and it keeps on failing to install the rom. Is there a rom for the SM-T805.
[Galaxy Tab S Android Development] paradroid28:
Yes - the title is misleading - has a typo ;-)

[Galaxy Tab S Android Development] maelstromm:
Running into the same issues as some others here with my T700. Tried flashing with and without gapps but still stuck on logo screen. Wondering if I should flash back to stock and then try again.
[Galaxy Tab S Android Development] xthakila:
Sometimes it does that. This always does the trick for me.

1. Flash rom. Wipe cache

2. Boot into os.

3. Reboot to twrp flash gapps. Wipe cache.

4. Reboot into os.
[Galaxy Tab S Android Development] toscha42:
Depending on from which ROM you're coming you may need to 'Format' data within TWRP. That's more than just wiping data and might be required.

Cheers

Toscha
[Galaxy Tab S Android Development] mckenzis:
Thanks for these settings. They've made a big difference on my SM-T700

The only thing I couldn't figure out was how to set up the zram. Anyone able to provide some direction?

TIA
[Galaxy Tab S Android Development] maelstromm:
No dice. I formatted everything and tried flashing from an sd card. And without gapps using the latest TWRP 3.3.1-0 (I incorrectly previously stated this was 3.5.9). Still stuck on the logo screen.
[Galaxy Tab S Android Development] minilandl:
A big thank you for building crdroid for this device testing everything works fine. Safeteynet passess with magisk. Haven't tried Netflix but video playback works fine using the jellyfin mobile app. I found you need to use micro gapps as anything larger doesn't work . SD card and adoptive storage also works fine.

It's amazing to have Android 10 on a device from 2015 the experience is very close to a pixel C a bit slow but that's expected due to the age of the device. I'm not complaining overall I'm very happy even if it's a bit slow.
[Galaxy Tab S Android Development] maelstromm:
Finally got it working using the silliest of things to do. This time, i skipped installing TWRP as an App and it booted in 5 mins without Gapps. Installed Gapps nano and it still loads quickly. Now to truly test this build. Thank you for all those who patiently tried to help me troubleshoot.
[Galaxy Tab S Android Development] ashton4life:
Hi there,

I appreciate the info! My problem is I keep getting a message telling me my tablet isn't rooted when I try to run Smartpack Kernel Manager. Any app that requires rooting is telling me this. I rooted it again in Odin and still the same problem. Any thing I can do?
[Galaxy Tab S Android Development] sdno:
Hi, Did you solve the netflix error 6.0??
[Galaxy Tab S Android Development] toscha42:
With LineageOS you better should use Magisk for having the device rooted.

Cheers

Toscha
[Galaxy Tab S Android Development] ruthless10001:
No, sorry i just stuck there for a while then had to go back sd if i have any progress i will share..
[Galaxy Tab S Android Development] minilandl:
Yes root apps expect to be on internal storage because they need access to the root directory / so they only work correctly on the internal storage. I had this issue with fkm moving it to internal storage fixes this.
[Galaxy Tab S Android Development] minilandl:
Apps seem to be force closing I presume this is due to lack of ram or some web thing this happens on both jellyfin and Firefox both installed on the SD card
[Galaxy Tab S Android Development] sdno:
That's okay. Thank you for your reply :)
[Galaxy Tab S Android Development] ashton4life:
Thank you for the reply! Yes I figured that one out last night and its working fine now.

Working on a SM-T700

I'm not too savy at this so I'm sorry for my jibberish! lol

After cleaning up a few options in settings like turning off the Google news on the left swipe panel as well as cancelling out the Samsung UI new install app to stop the annoying finish installation notice that keeps crashing, I've been able to get it running very well using the smartpack kernel manager as described by mckensis. I am testing for battery life now. I can confirm video recording crashes but pictures work. The mic doesn't seem to work either. The speaker seems to work but the volume is very low at max. Is there a fix to raise max volume? Does editing the mixer_paths.XML work to raise the volume? VLC media player adds more volume but playing youtube videos gives me very low volume. I tried to edit the mixer_paths.XML file but it wont save my edit using ES File manager or another root editor. Anyone figure this out?

Update: I installed Solid explorer to see the root file and Quickedit to make the changes to the file and bingo it worked to raise the speaker volume. I changed the "speaker" figure from 122 to 142 and it works great with youtube videos now. I didn't go higher just to be safe since I can feel the speaker vibrating in my hand now! If anyone needs the exact method in detail let me know! Also, the volume settings for the headphones are the there if you wish to try that too. :)
[Galaxy Tab S Android Development] mckenzis:
Will give it a try. Thanks for the info

It was actually @xthakila that described using smartpack. Thanks to him!
[Galaxy Tab S Android Development] ashton4life:
Hello!

I know how lowering the resolution on PC's normally speeds up graphics and the overall usability. I was wondering if changing the resolution helps take out some of the lag and speed up the overall use of the tablet? Is it worth it?
[Galaxy Tab S Android Development] djtallman:
Running it on my smt700 for a week now, awesome, only aroma variant of gapps worked for me! Thank you very much!
[Galaxy Tab S Android Development] CrackPL:
I just installed lineage-17.1-20220619-UNOFFICIAL-klimtwifi on SM-T700, with BiTGApps, so this also works.
[Galaxy Tab S Android Development] porcino:
It's about spreading heat from the CPU to the battery, frame and rear lid...

Sorry, I would rather not open the device now, because I also put some thermal paste under the rear lid... It is simple to explain without pictures. I used adhesive aluminium tape, about 5cm width. It is thin, so multiple layers are needed, say 5. You can't miss the processor - it's the hot metal plate to the North of the battery (near the camera). Lay the strips of the tape from the processor across the whole battery. Removing the lid is a bit fiddly - start from the USB port and use a couple of thin plastic implements (cards, guitar picks or collar tabs).

I've noticed that the kernel does not support HMP (8 cores simultaneously), although EXYNOS5420 is able to do that, and Linux for Odroid XU3 (EXYNOS5422) supports it beautifully. Sadly, one can't have it all...
[Galaxy Tab S Android Development] Jed D`Lagged:
Just bumping because I, too, have noticed that Mobile Data does not work with Luis's Lineage 17.1 or crDroid release. klimtlte, SM-T705

It can read the SIM (AP info pulled from SIM and displayed), but it does not seem to be able to communicate over the mobile broadband. Searching for other networks produces no results. I can force 3g over LTE, and my Mobile indicator shows a signal over no signal, but I still cannot connect to any AP, and searching for other networks is still blank.

SMS and Phonecalls work fine.

Wifi is fine

Bluetooth is... working, with some tweaking but I think those issues are unrelated.

I restored the Modem from my Lineage 14.1 backup, but the problem persisted.

It seems like a Logcat has already been produced, but if there's anything else anyone needs to help fix this I'm more than happy to help.
[Galaxy Tab S Android Development] bluess57:
Grab a logcat of radio topic

I know it talks about APN information, and I know the information it's showing in the log is legitimate. Hopefully this helps.

EDIT: I'm attaching the logcat but it's not showing on the post?

EDIT: Is there some kind of anti-logcat upload thing going on? I can upload basically anything EXCEPT this particular logcat file

EDIT: I put it in a RAR
[Galaxy Tab S Android Development] bluess57:
probably a file size limit. Host it somewhere, pm the link and I can take a look.

Unfortunately I'm awaiting tablet parts in the mail to get my SM-T805 back up and working (Prob a week or 2 away).

RILD logs everything as error category, so it's not easy to figure out if messages are real errors or not.

All the usual disclaimers ... Use at your own risk, I'm not responsibile if you brick your device.

Mobile data LTE works for me.

Video recording is broken still.

I don't know if anything else is broken.

Do a backup (if wanted) & WIPE FIRST.

This is a Selinux enforcing build.

The .apks are signed.

I don't use Magisk so don't ask me.

I will/can provide OTA updates for short period (whilst the Azure subscription lasts)

Yep I don't get LTE signal strength bars in the icon ,not all that important I guess.

I've found a lead on why video recording is broken, so I may be able to fix.

BTW the ondemand kernel governor seems a little laggy, so I'm trying the interactive governor instead, and I'll look at a deathly kernel build.

hey there!

I am having a strange issue with wifi on the latest builds for my SM-T800, both lineage and crdroid (lineage-17.1-20220619-UNOFFICIAL-chagallwifi). On stock android 6.0.1, everything works fine.

When I flash the lineage build, it boots properly, but is unable to connect to my mesh wifi network (saying to check the password and try again).

I have tried disabling the 5Ghz band to see if that was the cause, but I'm still getting the same issue. I know I have the password correct. Has anyone else seen this?

edit: after some more testing, this appears to be happening on minashokry's Lineage 17.1 builds as well, which makes me think this is a lineage issue. Lineage 15.1 and below works fine.

edit2: after even more testing, it looks like it has something to do with the security algo the network uses. I've tried "WPA2-PSK [AES]" and "WPA2-PSK + WPA-PSK[TKIP]" with no luck. If the network is unsecured, it works fine.
[Galaxy Tab S Android Development] pacc:
Many bugs are from component drivers, some are broken (ex. Mic on T700), some unstable and some work, unfortunately it seems to me this won't change any time soon.

First of all thank you all to help revive this device. I was using LOS 14.1. But now I’m confused. Can you give me a tip or something to install the "1. Flash latest official Samsung Firmware with ODIN"?

I tried search but I didn’t found many things. 1) How can I check/how can I know if I have the last Firmware? 2) In this site [https://sfirmware.com/samsung-sm-t800/] I found 2 files, one with the signal BIN (whats mean)? T800XXS1CSA1 (SM-T800_1_20190220102753_6o8ddzq9r1_fac.zip) (BIN one) and T800XXS1CSA1 (SM-T800_1_20190207222540_qevr4ncexn.zip)

Which one should I use?

I’m using now the "crDroidAndroid-10.0-20220618-chagallwifi-v6.27-LuisROM" with "the open_gapps-arm-10.0-pico-20220215" and it seems running very well.

EDIT:

I correct the name of the files. The both zip files are from 2019.
[Galaxy Tab S Android Development] runekock:
1) If your Tab has been running Samsung firmware, then you're probably already at the latest version. Generally, any Samsung marshmallow version is okay. This is just a precaution for those that haven't kept up with Samsung's updates, or have flashed weird stuff previously.

2) https://www.sammobile.com/firmwares/ has a good list of what Samsung has published for the different countries (not that the country really matters for a T800). Normally, I'd expect a CS version to be later than a CP one, so maybe your site has the dates wrong.
[Galaxy Tab S Android Development] hit321:
In the same files BIN and Normal theres files with name CS.

In the BIN file (T800XXS1CSA1 (SM-T800_1_20190220102753_6o8ddzq9r1_fac) there’s:

1. AP_T800XXS1CSA1_CL9407408_QB21693310_REV00_user_low_ship.tar.md5

2. BL_T800XXS1CSA1_CL9407408_QB21693310_REV00_user_low_ship.tar.md5

3. CSC_ZTO_T800ZTO1CSA1_CL9407408_QB21731972_REV00_user_low_noship.tar.md5

In the "normal" file (T800XXU1CPHD (SM-T800_1_20190207222540_qevr4ncexn.zip)) there’s a single file:

1. T800XXS1CSA1_T800ZTO1CSA1_HOME.tar.md5

So which one should I use and how to install it?
