I bought my T705 Tab 8.4 october 2018,

actually lineage-14.1-20211231-UNOFFICIAL-klimtlte

installed on it and it works fine so far.

I installed lineage-17.1-20220223-UNOFFICIAL-klimtlte.zip

open_gapps-arm-10.0-tvmini-20220215.zip

on it using twrp-3.6.1_9-0-klimtlte.img

but it works unstable - so I switched back to 14.1

Is there a way to find out, which official Samsung Firmware I had installed on it?

Baseband-Version is T705XXU1CPH3

latest nandroid-backup I find is named 2018-07-22--07-58-07_MMB29KT705XXU1CPJ4

latest firmware I find is

6.0.1 T705XXU1CPJ4 from 2016-11-22

Latest Samsung GALAXY Tab S (SM-T705) - DBT firmware

All Samsung firmwares for GALAXY Tab S in Germany with model code SM-T705. We offer free and fast download options. Check them out now.

www.sammobile.com

Looks like my latest backup already was based on latest firmware.

So I wonder, why 17.1 was running unstable :confused:

I checked battery-contacts lately as well.

THX in advance
[Galaxy Tab S Android Development] :
Not unless you recorded it at the time, but anyhow, any stock rom for that model would be fine, as long as it has your language, just find the latest or the oldone that suits;

Just make sure you have the correct model; then sift through the sites and see which is reputable and free.

For examples yours is T705XXU1CPH3 (NEE); here is one:

https://galaxyfirmware.com/model/SM-T705/NEE/T705XXU1CPH3

https://samfw.com/firmware/SM-T705/NEE/T705XXU1CPH3

Possibly the older one is something like this?

Have anybody tested if the May 2022 build supports LTE data @ Samsung Galaxy Tab S 10.5 LTE (chagalllte) SM-T805?
[Galaxy Tab S Android Development] HYKK:
Does this rom work for T805K Korean version lte? It has exynos 5433. I tried flashing t805 twrp for the device but didnt worked. Although I could make twrp for my device I wonder if this rom would be compatible with my t805k because the cpu is bit different
[Galaxy Tab S Android Development] OldButNotObsolete:
@Skyh, FYI, the Libby feature of Settings, Accessibility, Reduce Motion = On made a slightly noticably improvement, if you haven't tried it.

[Galaxy Tab S Android Development] pacc:
To anyone on klimtwifi (T700), is the new May update with mic still broken?
[Galaxy Tab S Android Development] teohub:
Yes. Mic still doesn't work on latest crdroid for t700. Hope Dev will fix it in future builds. So far a good rom.
[Galaxy Tab S Android Development] emon1618:
ok so I unzipped the crdroid file for the sm-t800 (chagalwifi). I actually didn't know about error 7 until now (since I've only learned how to flash official builds before) but yeah I removed that assets portion in updater script and recompressed the whole folder again to unzip in twrp.

The problem arose with the newest arm 10 pico gapps file when I booted into the system - speech services would crash and I was forced to connect to the wifi since there was no skip option, so the thing kept reloading and trying to find updates.

Luckily I had a file for arm 10 pico from June 2020 so I unzipped that and was able to access the rom. I tried some of the customization features like pulse visualizer which was laggy and the default browser would start glitching a bit, I am able to pair my devices with the tablet via bluetooth like my earphones but still cant nearby share but the tablet is functional.
[Galaxy Tab S Android Development] mithrandir42:
Not exactly with Tab S 10 (chagalllte) , but with SM-T705(klimtlte): No mobile data with SM-T05 with the May build.
[Galaxy Tab S Android Development] Matt_Selvans:
Installed Rom from the mentioned link

This rom lineage-17.1-20220504-UNOFFICIAL-chagalllte.zip 2022-05-06 15:36 436M

On my Sm-T805

but I had to remove the assert line from META-INF\com\google\android\updater-script cuz it was giving me error 7

I tried flashing open_gapps-arm-10.0-aroma-20220503.zip and open_gapps-arm-10.0-pico-20220503.zip

Both X86 arm

But google services crash

So I followed the advice from this link

Detailed Guide for LineageOS 17.1 on Samsung Galaxy Tab S (SM-T805)

Detailed Guide for LineageOS 17.1 on Samsung Galaxy Tab S (SM-T805) - main.md

gist.github.com

Which says

Broken play services:

Download apk compatible with android 10, arm, (nodpi)

-I downloaded this one Google Play services 21.42.59 (120700-410919843) (120700) APK

-From https://www.apkmirror.com/apk/googl...s_slug":["nodpi"],"minapi_slug":"minapi-29"}/

unlock develoepr options

enable adb debugging + root debugging

adb root

adb remount

copy apk into /system/app

chmod 644 this apk

reboot

But Google services keeps crashing

I would love to find a solution. Thank you in advance
[Galaxy Tab S Android Development] Alesky07:
Open gapps did not work for me causing bootloop (Trying many times). But I have success the first time with BiTGapps.
[Galaxy Tab S Android Development] Andrey.a.b:
hello, after the last update it gives an error, how can I solve it?
[Galaxy Tab S Android Development] CessnaBroon:
Try connecting again, if that doesn't work, click another network, it'll probably let you continue with setup, and you can connect manually, and it'll prompt you to complete Setup through the Wizard. Hope this helps
[Galaxy Tab S Android Development] LeWZ:
Happened to me too with my T805. Would also really like a solution!
[Galaxy Tab S Android Development] son1c:
Flashed the newest build on my T-700 but after selecting my Wifi nothing happens. i then go back and and press next again it start searching for updates and shows the wlan symbol on top, then it just states "No internet connection". Tried diffrent gapps and the cr droid version too, anybody knows how to fix this?
[Galaxy Tab S Android Development] son1c:
yeah, thats exactly my issue
[Galaxy Tab S Android Development] W@$T3:
Same problem here. Wanted to bring my Tab back to live but unfortunately no Wifi works. Tried several Wifis and a HotSpot.

When I only flash the ROM without Gapps, it will boot direct into LOS Startupscreen and not into Google Setupscreen.
[Galaxy Tab S Android Development] sacalul:
Same problem here ... no Wifi ... any help? pls
[Galaxy Tab S Android Development] wolus666:
Same here. Flashed rom and pico Gaaps, stuck at wifi. If I don't install gapps during rom flash then the tablet goes into lineageos bootloop.

PS: I was flasing from LineageOS 14.1 with latest TWRP
[Galaxy Tab S Android Development] wolus666:
Can you elaborate what is "wiped evrything"? data, cache, dalvik or system also?
[Galaxy Tab S Android Development] ID000001:
Everything as in everything. All of the above. Plus whatever other options

I install it from a MicroSD card so that is the only thing I didn't wipe.
[Galaxy Tab S Android Development] wolus666:
Hi whatdo you call a full wipe in TWRP?
[Galaxy Tab S Android Development] wolus666:
I did wipe all, still same issue with wifi and checking updates
[Galaxy Tab S Android Development] ID000001:
No wifi issues with my SM-T800. I remember checking the update part needed a hard reboot once though.
[Galaxy Tab S Android Development] runekock:
Just a general remark - I haven't tried the new build myself:

OpenGapps tends to be broken some of the time. If you can't find a known-good build, you are better off with another gapps, such as MindTheGapps.

Redirecting…

Edit: see messages below: @wolus666 tested MindTheGapps as not working. @Athawulf recommends BitGapps.
[Galaxy Tab S Android Development] wolus666:
i'm on klimtwifi (sm-t700)

MindTheGapps do not even install and are throwing error cannot mount system partition.

Opengapps install normally but wifi does not work and stuck at checking for updates

Now trying older gaaps
[Galaxy Tab S Android Development] wolus666:
For all those having issue with wifi and not being able to skip check for updates. I solved it by installing older Gapps , try version PICO from January 2022.

EDIT. After using it for few hours i spotted that in chrome the touch input is shifted, have to click like 5mm above. Also in chrome when I play video fullscreen the boundaries of video are beyond screen.

Anyone knows how to fix?
[Galaxy Tab S Android Development] Athawulf:
use bitgapps
[Galaxy Tab S Android Development] wolus666:
You mean to fix the touch screen misalignment?
[Galaxy Tab S Android Development] Giblet535:
I'll confirm that wifi does not work on t705, with or without gapps.

(Simplest install: Wipe data, cache, dalvik, then flash only the rom)

The symptom is "authentication failed" or "wrong password, try again" during initial wifi setup. If you skip past initial setup and try from Settings, same error.

Edit: The crdroid variant's wifi doesn't work on a t705 either. Same error.

Interesting. LOS 14.1 won't boot (boot logo forever). CM12 is the same. I presume that's a Last Vendor Update weirdness in ... partitioning, maybe?

I flashed stock just to be certain I could and to re-re-test wifi from the device. It works fine. Is this likely to be an issue correctible by building from Luis' code manually and grabbing the stock ROM's props files with the LOS provided script? Lordy that's big...
[Galaxy Tab S Android Development] foolone:
I have open_gapps-arm-10.0-mini-20210901, which works well with the new build on T800
[Galaxy Tab S Android Development] Kate6:
Follow the guide at https://wiki.lineageos.org/devices/chagallwifi/build with the following two changes -

(1) When initializing your repo, use "-b lineage-17.1" instead of "-b cm14.1" at the end of your "repo init" command.

(2) After you run "repo sync" grab a copy of https://github.com/exynos5420/manifests/blob/lineage-17.1/roomservice.xml, put it in ~/android/lineage/.repo/local_manifests/roomservice.xml and then run "repo sync" again

(3) Profit!

... You're welcome.
[Galaxy Tab S Android Development] BombGuns:
Greetings! Does anyone know how to restore the operation of LTE networks on t705? A very good assembly, but without mobile data, the tablet is castrated somehow. Its most important functional does not work.
[Galaxy Tab S Android Development] porcino:
Is anybody else having problems with video playback with this ROM on SM-T800? In Brave/Chrome/Firefox videos are rendered in a wrong scale, which also depends on the resolution of the stream. In many web sites the resolution of videos changes dynamically, thus resulting in erratic change of the scale.

The last ROM free of this bug seems to be a good old LOS-14.1, with which I am stuck for now due to the video playback issue...

https://xdaforums.com/t/rom-7-1-2-unofficial-lineageos-14-1-sm-t800.3545080/

Playing the videos outside the browser in an additional app is not an option, because all bookmarks are stored in the browser.
[Galaxy Tab S Android Development] hberntsen:
Thanks a lot! For convenience, I created a repo that can build the image in Docker https://github.com/hberntsen/docker-lineage-cicd-sm-t800
[Galaxy Tab S Android Development] Athawulf:
no it is to prevent the google play service error that happened to me with the gapps indicated in the first post
[Galaxy Tab S Android Development] SkOrPn:
For me and my T700 this build has so far worked well. However I am reporting very early as I just finished the install an hour ago. I was on RR 5.8.5 (7.1.2) from Dec 2020 (or was it 2019?) and I already had TWRP 3.3 and easily flashed twrp 3.6 img (latest as of today) with no issues. Then I wiped everything (except microsd and usb otg) with no issues. I then installed LineageOS 17.1 20220504 and open_gapps-arm-10.0-mini-20220110.zip (first build of the year I believe). Everything went well, it signed into my wifi without issues and all the apps updated. I did not transfer data from googles cloud as I wanted it to run as is. Fired up the play store and updated more of the already installed apps without issues. Going to install brave, a dedicated video app and my file manager of choice and be done with it.

So far I am having no issues. Going to use this for mainly watching movies during camping and some rare web browsing, maybe some email checking every now and then. Overall I am impressed that it is running as smoothly as it is.

Thanks for the Android 10 love on this old tablet.... I was shocked to see this available.... lol
[Galaxy Tab S Android Development] a3r0n1:

[Galaxy Tab S Android Development] a3r0n1:
Many Thanks, @8224Freak

T800: Only used for media/browsing and mucking about.

Installed without issue, Twrp wipe, Pico and Magisk.

Wifi 5Ghz, and BT pairing. All good. (Headphones)

Video playback in Brave and Kiwi browser, working.

Battery life is excellent with no significant drains.

Music player/Eq, camera, torch, location, airplane mode, battery saver and settings all work.

Rom feels fluid and problem-free. for me.

Works right out of the box. (3 days of testing without mishap)

Breathed new life into my forgotten tablet.

Outstanding work!

Thanks again.

Update: Reduced the screen resolution to 1920x1200 and DPI to 240 as suggested by @Ledah

Positive impact on performance.

App: Easy DPI changer.

Thanks.
[Galaxy Tab S Android Development] wolus666:
try gapps version PICO from January 2022.
[Galaxy Tab S Android Development] porcino:
The DPI Changer... Is it the same as running the following?

adb shell wm size 1920x1200

adb shell wm density 240

adb shell reboot

(an option is to try 1280x800 160 - looks a bit washed out in GUI)

The original values are 2560x1600 and 320 (in case one needs to restore the settings). These can be read by running

adb shell dumpsys display | grep mBaseDisplayInfo

Have you checked playback of videos extensively? What I saw when trying this ROM a while ago was that the videos were played, but frequently the scaling of the video was changing, so it became "zoomed" on the left part of it. Could you please test this with youtube videos played in Brave or any other browser?

If setting up the lower resolution helps, then it is time to celebrate!
[Galaxy Tab S Android Development] a3r0n1:
I haven't done any extensive testing, just light to medium use.

I don't game on it. Used for media, browsing, and tinkering around of late.

Unable to comment on Adb, but probably the same result.

App is straightforward.

Scaling @1920x1200/240, no video playback problems. (YT/Twitch)

Currently using the 1280x800/160, I'm assuming it's less demanding on hardware/battery, and visual not all that different, I could be wrong tho.

Found "Kiwi" browser to be faster in loading times than Brave, also being able to add extensions is a plus. (more tinkering^^)

No crashes or serious flaws to report.
[Galaxy Tab S Android Development] porcino:
Thanks. Tried this ROM again (lineage-17.1-20220504-UNOFFICIAL-chagallwifi), different screen resolutions, different screen densities - still intermittent video playback issues in browsers including Brave. The fault manifests itself as the video being zoomed in occasionally (not always), so that only a part of it remains visible.

I must say, however, that this ROM is faster than LOS-17.1 by minashorky when playing videos.

So, going back to the old lineage-14.1-20220107-UNOFFICIAL-chagallwifi, which feels cleaner, much faster and has SELinux+encryption working.
[Galaxy Tab S Android Development] amrsh0009:

I

'm stuck with combination file

on my T705 I got from https://samsungcombinationfile.com/flash-samsung-combination-firmware

COMBINATION_OXA_FA44_T705XXU1AOC1_OXA_1725373_REV00_user_mid_noship.tar.md5

I flashed it, using Odin3_v3.14.4 , but there's no working recovery-mode.

Since I flashed that only flashing this leads to "PASS",

other flashing attempts with odin lead to "FAIL" - tried

SM-T705_NEE_T705XXU1CPH3_T705NEE1CPH4_T705XXU1CPH3_T705XXU1CPH3

twrp-3.6.1_9-0-klimtlte.img.tar

SM-T705_1_20161226141339_4b12u2bjgf

(I tried this because I didn't get OEM UNLOCK neither after several attempts with date-tweak nor after waiting for more than 2 weeks)

I'd be grateful for help.

Why u not answering on 4g not working? SM-T805. Even IR remote not working.
[Galaxy Tab S Android Development] Specktäter:
Thank you very much, this one worked for me.

I installed it over original firmware "DBT-T800XXU1CPHF-20161014121729", took the "lineage-17.1-20220504-UNOFFICIAL-chagallwifi" and "open_gapps-arm-10.0-nano-20220215". Had to set the Wifi 2x, since there no bugs seen.

I have two questions: how can i enable/reinstall the Samsung Kids mode with this operating system?

And the original firmware looked for my eyes before disabling the display - how can i enable this function here?

Thanks again for your hard work!

Find the TWRP of the .img extension (not the .tar)

root with a one click root app like kingroot or kingoroot

use flashify or whatever to flash the TWRP.img into recovery.
[Galaxy Tab S Android Development] xdafant:
Thank you very much - you helped me out of THIS trap!

Now I got a new problem I haven't experienced yet

twrp-3.6.1_9-0-klimtlte could't install - Failed to mount "/hidden". I found one old thread from 2018 that ended without solution.

So I'm stuck again at another stage :-(

Odin couldn't install T705XXU1CPH3_T705NEE1CPH4_T705XXU1CPH3_HOME.tar.md5 as well - FAIL (last message "cache.img")

Complete(Write) operation failed.

Odin still only capable of installing Combination file :(

Reminds me of the film "Groundhog Day" "Und täglich grüßt das Murmeltier" in german :sick:
[Galaxy Tab S Android Development] runekock:
Try Heimdall instead of Odin, like described in the old LineageOS wiki:

Install LineageOS on klimtwifi | LineageOS Wiki

wiki.lineageos.org

(This is for T700, but the T705 should be similar).
[Galaxy Tab S Android Development] Petyay:
This is the biggest problem in my opinion.

I do not understand why the author of the topic does not indicate in the first message that LTE data does not work so far !!!
[Galaxy Tab S Android Development] LR7875:
You can request, however the developer has not been since April, so maybe wait a while.
[Galaxy Tab S Android Development] QuiGonJinn37:
Same problem as many with a SM-T800, the WIFI dosen't work, "Check Password and try again" message or "Authentification problem". It only works with my Galaxy S20 FE in Hotspot mode.

[Galaxy Tab S Android Development] LR7875:

To fix most internet related problems such as video playback errors on live tv websites etc update webview to build : Android System WebView_v102.0.5005.78 maybe developers can also do that in the next build , The Rom is working very good now.

Hi I found my old t705 in the cupboard and was just needing a stable version, with wifi, doesnt have to be the latest and greatest just stable with wifi. Can anyone point me in the direction of a stable version thanks again.
[Galaxy Tab S Android Development] runekock:
The unofficial LineageOS 14.1 is generally considered the most stable for these tabs. Here is the download link:

index - powered by h5ai v0.30.0 (https://larsjung.de/h5ai/)

index - powered by h5ai v0.30.0 (https://larsjung.de/h5ai/)

download.exynos5420.com

I'm sure there is a forum thread somewhere as well.

The roms in this thread are more beta-quality: many things work great, but bugs exist. E.g. missing LTE and the mike not working.
[Galaxy Tab S Android Development] LR7875:
@roscore1000 only asks for wifi rom. Is there any bugs except LTE for this android 10?
[Galaxy Tab S Android Development] runekock:
1) When I tried it on a T800 late last year, there was some stuttering in streaming video

2) Some people report WiFi not working - I assume it depends on the settings of their router

3) Microphone not working on some models (T700+705, I think)

4) SE-Linux permissive according to reports. Without SE-Linux, Android has very little protection against malicious apps
