No worries. I had to find a new version of ODIN (since it's been atleast 1 year), ODIN-ed also latest TWRP, then Installed the Lineage ROM file at op's post.

Booted and worked.

So you don't really need to install original Samsung's last avaialble firmware (which is a good step to skil-as it's hard to find nowadays).
[Galaxy Tab S Android Development] cicisbeus:
The real problem with Lineage Os 17.1 are Gapps.

With the various replacements of Android System Webview, cache cleaning and clearing of storage spaces of the various apps, I had reached a decent stability, with some sporadic crashes of Chrome.

I have continued to study the problem that depends on the fact that the various Google apps interact with each other and. in fact, the developers who deal with it do daily tests to verify the interactions with the various updated components.

The latest Open Gapps are from today 8 July, but not yet available for download.

Instead, those of yesterday 7 July can be downloaded.

I downloaded the latter (Micro) and reflashed with TWRP, then wipe cache and Dalvick / Art, rebooted the system.

Lineage OS booted smoothly and after 2 hours of work no Chrome or other apps crash
[Galaxy Tab S Android Development] vpn560:
Whenever one tell about stability, a new app termination occured. No matter, with or without GAPPS. This firmware is the matter.

Аmong other things, I encountered a low sound volume.

Virustotal indicates viruses in the most of recent Webviewes. I have found some virus free items among major indexes of 84, 86, 88 and 91.

i don't know why my t705 clean flash, when i'm trying to use some apps including magisk app, the device will freeze and i have to force reboot
[Galaxy Tab S Android Development] SamuTnT:
Hi all, SM-T705 (klimtlte) here, anyone with this device has the fingerprint sensor working?
[Galaxy Tab S Android Development] steamrollerpark:
Trichromelibrary apk is what is missing. I reinstalled without GApps and when I tried to install Chrome I got the message to install Trichrome. Webview is not really the problem.

You can get Trichrome at APK Mirror.
[Galaxy Tab S Android Development] glennza:
I installed the latest Trichrome Library from APK Mirror but it made no difference
[Galaxy Tab S Android Development] fussle:
wowow - thank you so much for this build.

i do a dirty flash over the latest louis build for T-805 from 2020 - and - it works perfect
[Galaxy Tab S Android Development] vpn560:
it seems that Trichrome lib is needed with Webview.dev only and in any case does not affect on stability.

You will be surprised checking Webview.dev at virustota!.com.
[Galaxy Tab S Android Development] Nick2204:
T805 - A bit of stuffing around with getting TWRP installed, but lineage build with gapps (micro) working great.

My son installed all the apps he needed from chrome to zoom etc, and did home schooling on it all day with no hiccups.

Thanks!
[Galaxy Tab S Android Development] Marks_it:
Many many thanks.

Was running your rr for the chagallte, I followed the instructions.....working perfectly. I did note some lag initially but changed setting from balanced to performance in battery settings and now it screams along.

Thanks again @8224Freak

[Galaxy Tab S Android Development] masdaster:
Hi,

First of all: Thank you very much for this up-to-date ROM!!

Thank you too for your hard work optimizing the ROM!

I've got a SM-T805 and I would really appreciate using your modified boot.img. I've installed it today. It is stuck showing splash screen. I've extracted last_kmsg. Can you need it for fixing?
[Galaxy Tab S Android Development] ISoreo:
if you have logcat file or last kmsg please attach, i will look the it

while it booting up if it stuck at samsung logo please use adb logcat -b all -v time > sm-t805.txt
[Galaxy Tab S Android Development] masdaster:
Thanks for your reply! And of course your effort!

Unfortunately I cannot record a logcat file because the adb interface isn't ready until it stucks. I've tried it two times and there was no device recognized.

Attached you can find my last_kmsg file. I pulled it with TWRP right after a bootloop. I really hope, you can fix it soon and I will be happy to try it out!

--- Edit ---

Sorry... I don't know why, but I cannot attache files. They are removed from the post after saving. Here is a link:

[Galaxy Tab S Android Development] ISoreo:
you can do it while connecting the computer you can use adb to record file, ok if not work back to stock boot and then enable adb and flash my boot.img then if it stuck you can recording the logcat file while it stucking in bootsplash
[Galaxy Tab S Android Development] masdaster:
Thanks! Now I could record a logcat file! :)

Sorry. I still cannot attach files. I don't know why... :(

are you using crDroid? cuz i'm build for lineage only not for crDroid
[Galaxy Tab S Android Development] masdaster:
Yes. At the moment I'm using crDroid. If this is a problem, I will switch. Gaining performance would make me go back again. ;)

It's the same base, as far as I know. Do you think, using your boot.img with crDroid can cause problems?
[Galaxy Tab S Android Development] ISoreo:
i don't know much because this first time for my tab s 8.4" i using Lineage for a while and i build boot image for lineage only, i'm not sure i config the driver correct or not
[Galaxy Tab S Android Development] Skyh:
I decided to install this ROM today, and honestly I find it not to be smooth at all, the interface really is pretty choppy and laggy.

Anybody else find this to be the case, or was there something they did in order to fix it? I didn't find that changing the resolution did really much of anything at all, certainly didn't make it any better. When I disabled HW Overlays that made some stuff a touch smoother, but overall everything was just really choppy.

Any suggestions?
[Galaxy Tab S Android Development] maxq1:
^ use @ISoreo's kernel
[Galaxy Tab S Android Development] kodiak799:
Where is this kernel? Thanks

I came from resurrection remix, but had been on the latest official firmware. klimtwifi (T-700), and it's been pretty laggy for me. Most of the bugs other people reported, and fixes aren't working for me. Also, really weird that I can't uninstall system apps - tried every method, even Titanium and ADB.

I also found LOS14.1 to be similarly laggy. RR runs this thing like a new device, but because of its age newer apps don't want to work on it. Going to try flashing crDroid and see how that goes.

Still quite the achievement for a device nearly 7 years old. Form factor is perfect, IMO, and the screen resolution still blows away most of the new tablets out there.
[Galaxy Tab S Android Development] maxq1:
on t700 too. using this one. came from RR too then LOS 14.1 deathly then this

adjusted some mem kernel settings too via franco kernel mgr. min free mem defaults to 2839 KiB and zram at 1384 MiB. using 1028 KiB (figured it should be smaller than default as the t700 only has 3gb of ram) and 4096 MiB, respectively. working so far for my use case. background apps aren't easily off'd. chrome and netflix work though i still get some occasional launcher redraws. thinking this is coz of nova7 but i might be wrong
[Galaxy Tab S Android Development] Skyh:
I haven't really been able to figure this out from the thread, is the kernel compatible with the T-800?
[Galaxy Tab S Android Development] maxq1:
^ not sure but none works yet. kernel settings i posted might help though
[Galaxy Tab S Android Development] ISoreo:

[Galaxy Tab S Android Development] masdaster:
@ISoreo

May I ask if I can expect one more build from you for my SM-T805 chagalllte? I would really appreciate it. 🙂
[Galaxy Tab S Android Development] ISoreo:
i will try to build it, since i don't have that device also i'm not sure what's wrong when i build the image that make you guys unbootable
[Galaxy Tab S Android Development] masdaster:
Thank you very much!

If I can help a little bit, I would love to do so. Do you have some 'tutorials' or 'manuals' about building this? I'm a Java & C# programmer. So maybe I can learn how to build a kernel and help you with this device... 😅
[Galaxy Tab S Android Development] ISoreo:
you can find the source from first page and lineageOS website how to build kernel also rom
[Galaxy Tab S Android Development] toscha42:
Just curious where did you find crDroid for Tab S (SM-T805)? I googled it but just found some statistics but no link to the ROM itself.

Cheers

Toscha
[Galaxy Tab S Android Development] masdaster:
Just open the link in first post:

LuisROM / LuisKERNEL / Firmware / Misc

Below the lineageOS builds you will find the crDroid builds.
[Galaxy Tab S Android Development] masdaster:
Okay... I'll try to setup a build system... 😅

Can you send me your modifications please?
[Galaxy Tab S Android Development] ruthless10001:

[Galaxy Tab S Android Development] DiVisici:
Hi guys, sorry for being a noob but does anyone have step by step guide somewhere how to do it? I have never chose to venture into custom roms but I would like to try it.

Thanks!
[Galaxy Tab S Android Development] masdaster:
Hi DiVisici,

What device do you have and what is your current setup? Do you know something about Odin and TWRP?
[Galaxy Tab S Android Development] DiVisici:
Samsung Galaxy Tab S 10.5 LTE (chagalllte) SM-T805

I have read on a few occasions about the procedure but due to numerous options and steps that are a bit vague because most tutorials are usually general. I wouldn't take too much of anyone time, but if there is some new guide specifically for this one would be very helpful. Also, is wiping done from on device or complete wipe like clean windows install?
[Galaxy Tab S Android Development] masdaster:
Okay. I've got a SM-T805 too. Just follow the steps 8224Freak has posted.

If you are sure that your device has the latest firmware, you can skip step 1. This firmware is shipped with the regular updates from Samsung. If you have got all of them, you are fine. Due to the lag of updates provided by Samsung, the latest firmware is quite old. You can get it from several sources (e.g. SamMobile.com).

If your device is on stock ROM, you have to flash TWRP with Odin. Then all other steps need to be done with TWRP. Wiping data is also done with it.

Regarding your question if it is similar to a clean Windows installation:

You cannot really compare it. These systems are completely different. There are some partitions on an Android device (especially on new ones), you should NEVER wipe except if you REALLY know what you are doing. When installing Windows, you can wipe the entire disk, boot the ISO and you are fine. But Android ROMs do not contain the data of all the partitions. But these positions are only available, when you enter advanced wiping in TWRP and some are totally hidden unless you boot a modified TWRP version.
[Galaxy Tab S Android Development] masdaster:
I've successfully ported ISoreo's modifications to the SM-T805 chagalllte. My device is booting up fine and the system runs snappier. Apps are loading 'fast' and the animations are smoother (no stuttering). Thank you very much @ISoreo!!

The only modifications I didn't apply are all the governors ISoreo added. At the moment the default is ondemand which is the same as the default one of ISoreo's boot.img. If someone is missing them, I will add them in the future.

Here is the link for downloading:

Quick question on Upgrade from Lineage 14.1

I have a SM-T800 Chagallwifi currently running latest from https://download.exynos5420.com/LineageOS-14.1-Vanilla/chagallwifi/

Is it possible to upgrade to this OS without clean flash?

by using the approach detailed here for instance: https://wiki.lineageos.org/devices/klte/upgrade

I've read through the thread but have not seen a definitive answer on this.

Thanks!
[Galaxy Tab S Android Development] Limakos:
Jumping between 3 versions of Android system without clean flash is asking for trouble 😉
[Galaxy Tab S Android Development] cicisbeus:
From personal experience, with this Rom you need advanced wipes: data, system and cache (also dalvik / art).

Flash ROM and stop. Reboot into the system.

Then restart again in recovery and flash gapps
[Galaxy Tab S Android Development] Marks_it:
Thank you for this. Quick question. I download boot image and flash to boot partition in twrp? That's all?

Cheers.
[Galaxy Tab S Android Development] masdaster:
Yes. That's it. Additionally I cleared cache after that but I don't think that it is necessary.

Please backup your current boot.img to be safe if you find some bugs. ;)
[Galaxy Tab S Android Development] toscha42:
Many thanks!

Does it now also support the SIM card? That's not working here since I installed LOS 17.1. And as far as I can recall I'm not the only one.

Cheers

Toscha
[Galaxy Tab S Android Development] masdaster:
I did no modification regarding the SIM card. Can you grab a logcat please. Maybe we can fix it this way because I've no SIM in my device.
[Galaxy Tab S Android Development] ISoreo:
my opinion sim card should be rom and config idk, maybe my guess is wrong
[Galaxy Tab S Android Development] masdaster:
I think you refer yourself to this post?

Do you still have all of these issues? Do you have the latest firmware?

I thought that too. But he says that his device doesn't recognize the card. If it's on LineageOS side then you should see a card but you cannot use it. Maybe this has something to do with the driver configuration of the radio module.
[Galaxy Tab S Android Development] ISoreo:
some features might be build the rom to enable that feature i guess, also simcard might be in config or build.prop while building the rom or somekind that related to that issue
[Galaxy Tab S Android Development] Klaus20:
I have now installed LineageOS 17.1, boot_001.img and Magisk-v23.0.zip without an error message.

When installing the open_gapps-arm-10.0-stock-20210720.zip I always get the error 70.

In addition, the tab restarts every minute and the restart takes about 2 minutes ??

The Gapp error was already before the image and Magisk installation.

Does somebody has any idea ??

Have the following TAB: SM-T805 with a 256 GB Micro SD,

Regards Klaus

Addendum: The restart was probably due to the SD with the 128GB is no longer a restart.

Where can I find an explorer?
[Galaxy Tab S Android Development] masdaster:
Hi Klaus,

Our device can handle up to 128GB external storage. So your random restarts were likely caused by the SD.

When installing OpenGApps error 70 indicates that that there is not enough system space available. As mentioned earlier in this thread smaller packages are better for this device. Just install "pico" or "nano" and grab all other Google apps you need from the Play Store.
[Galaxy Tab S Android Development] Marks_it:
If it helps....don't flash stock gapps. Use Pico or another minimal gapps package and then load other apps you may need from the playstore.

I hope this helps.
[Galaxy Tab S Android Development] cicisbeus:
For Gapps, "micro" are also fine. I installed them on t800 and they work without error
[Galaxy Tab S Android Development] chevron9:
good morning ! I`m using a SM-T705 lte. Now i was delighted to see that there is an android 10 available. so i tried to install it. TWRP was already installed, which i updated... Now, after installing the 17.01. the system starts totally fine. After 1-3 minutes it just reboots. Gapps are not installed, just the 17.1.... any tips on a boot loop ?

thankful for any hints :-)
[Galaxy Tab S Android Development] masdaster:
Feel free to upload logcat and / or (last_)kmsg... 😉
[Galaxy Tab S Android Development] steamrollerpark:
No InfraRed for me, either.
[Galaxy Tab S Android Development] chevron9:
i really don`t know why... But.... The reasion why my tablet constantly rebooted was the... SD card ^^.... I unplugged the SD card and everything just worked fine. :) (Maybe the will be helpful for someone else ;) )

Tried a logcat, see attached. I'm not too experienced with it so in case it's too short just let me know. :)

[Galaxy Tab S Android Development] notasheepl:
I installed lineage OS chagallte with pico gapps and masdaster's boot image through magisk. I used to run the RR rom previous to updating to this.

For whatever reason, it randomly reboots a few minutes after unlocking, then after it does that repeatedly it will get stuck on the boot screen. The only way I have found to get back in is by forcibly disconnecting the battery, which I don't think is a very good thing to do.

Currently, I am running without the custom boot image, and it seems to be stable but a bit laggy.

Thanks for all the hard work everyone here has put in to keep our devices safe and up to date.
[Galaxy Tab S Android Development] zackteck:
Thank you for your work.
[Galaxy Tab S Android Development] masdaster:
It's not happening, when you have installed lineage's boot image? Can you reproduce it and get logcat for me? Maybe we can fix it. ;)
[Galaxy Tab S Android Development] masdaster:
Thank you very much! I'll take a look.
[Galaxy Tab S Android Development] notasheepl:
Stock boot image from 8224Freak's post with magisk works fine, though it is quite laggy.

It happens when the tablet is up and running at any time, mid-operation. Like in settings or any app. Sometimes, rows of thick black lines that seem to be equally spaced apart from each other appear over the screen before it reboots. All I need to do to reproduce it is flash the custom boot image.

Will upload the log as soon as I can.
[Galaxy Tab S Android Development] Sensational_:
Hi, Thanks for this update which was a welcome update for my T700 Klimwifi. I was getting a few freezes but have applied the boot001 fix and more importantly changed the dpi settings as advised which has made the system far less laggy and (fingers crossed) stopped the freezes / reboot. Keep up the good work!
[Galaxy Tab S Android Development] masdaster:
Unfortunately I could not find something suspicious up to now. Can you please send me one more logcat after switching air-plain-mode on and off twice?
[Galaxy Tab S Android Development] Machman19:
Thank you for your work. I have resurrected my old Tab S T805 LTE and it's working great. I had a little trouble with Android set up, but resolved that by installing nano Gapps and the ROM at the same time. Cheers a very happy man
[Galaxy Tab S Android Development] ISoreo:

[Galaxy Tab S Android Development] masdaster:
Thank you! I have excluded too many rows. xD

One other thing:

I've extracted Deathly Adiutor from LineageOS 14.1 because I could not find it anywhere. If someone needs it, here it is. All visible features are working with modified boot.img as far as I can see.
[Galaxy Tab S Android Development] notasheepl:
The first file shows the classic crash after unlocking the device. The black lines showed up like last time.

The second one was surprising.

After it crashed and rebooted itself, I unlocked it and it… DIDN'T REBOOT! For whatever reason it was “working smoothly” UI felt a lot smoother, so then I opened youtube, but the app kept crashing. A few times it was stable enough to play a video, but then it eventually crashed, and then I just left it on the home screen, and it was smooth, but then the whole thing crashed and rebooted like normal. Unfortunately, I didn't catch if the black lines showed up this time. Then I just restored the boot.img with twrp and went back to the stock image.

Hope this is useful.

Also, there is this weird thing with MTP.

I have to press File transfer then press midi for it to show up on my Windows 10 pc.

If I just press File transfer then windows just give me a “cannot recognize device” / “device malfunction” error.

Just something weird. If I do the midi thing I can transfer files to it.

And this might not be very important, but I have had it repaired by some random repair shop. It didn't charge, so I think they just replaced the USB port. And when it ran the RR rom there were 2 times when it froze, probably cause of overheating, the screen was stuck on the last frame it displayed and made the classic BSOD sound until it ran out of battery.

Edit: Unlike last time, this time the tablet was fully loaded up with everything and had 3 user profiles.

*Logcat removed*

[Galaxy Tab S Android Development] masdaster:
Thank you! Unfortunately I need more information and I cannot reproduce it on my device. I've installed YouTube but even when watching HQ videos, there was no crash... 🤔

Can you please upload last_kmsg after a crash? You can grab it with adb ("adb pull /proc/last_kmsg last_kmsg"), with a root file manager or with the file manager of TWRP. You can find it in "/proc".
