Thank you very much for detailed replies.

I will try a cooling solution during TWRP backup.

I am not sure how to do it, maybe a fan blowing over the back of the T800 or putting it into the refrigerator during backup (no joke).

I have used the latest stock firmware available on samfw.com for my country.
[Galaxy Tab S Android Development] shaglord:
The thermal mod that is suggested on the forum is to put a piece of thermal pad on the cpu shield so it can dissipate heat better into the back cover.

It won't let you to avoid thermal throttling but it can raise your max sustained clock from 1300 to 1400/1500/1600. I run my T805 at 1800MHz max but I don't have sustained loads. It can do 1800MHz for about a minute before thermal throttling. That's enough for me.

Oddly enough my smaller T700 can do 1900MHz with the same thermal mod.
[Galaxy Tab S Android Development] saoudien07:
From when I got this Tab, I used BTU region, dont remember why exactly. I am not even in UE region, there is no firmware for my country, I dont remember exactly why I choosed BTU, but work fine.

About the cooling solution, some will laught at us but yeah, I put it in freezer even! I put it on some glass cup, this way most surfaces is in contact with cold, also remove the cover off course.

TWRP Backup/Restore are exhosting for devices, even phone get super hot, and reach crazy temps. Still be carefull, about the freezer, you need to check on it everytime, because after a while, there is some humidity accumulated, and can be risky. So, I use to set a timer of like 5min for each check, and when I see to much water on the screen, I let it sit on table for some minutes, then back in freezer, or just in refrigirator. A bit jonggling, but it is fine for me, and dont stress much little poor Tab :)

There is another method I use for phone sometime, a PC fan with 2 brackets as fets, so a standing PC fan, it also does the job.

Another heat solution is to use so thermal pad as some pointed out around.

remember saw it long ago, but dit not give it a try, I dont use that Tab much, even if I have dismantle it a lot lol

[MOD] Thermal mod of T805/T800 boost performance by 150%

Thank you both very much for your suggestions.

The refrigerator/freezer method is a nice way for reliable backups (hihi).

I am not sure if I had the courage to open my old T800.

I have thermal pads available but I am afraid to kill the tablet.

I mostly just use my T800 for BubbleUpnp to control my audio playback.

I have to (find) a good video how to do the thermal mod. Maybe it's easier than I thought.

The additional cpu freq reduction to 1600 Mhz is very interesting to prevent throttling.
[Galaxy Tab S Android Development] saoudien07:
I also dont use that tab much lately, but gona need it soon, so want to give it a fresh up...

About its open process, I found it to be one of the easiest possible lol , just have to pup up back cover.

Not easy to explain it with words, but check videos.

Just need to remove back side for this mod.
[Galaxy Tab S Android Development] Qu@rk:
Thank you very much! That looks easy enough.

Hi there i was wondering which version of the hazou build that has not gotten the mic and camera issues for t705

thank you
[Galaxy Tab S Android Development] Charuzu:
Reading manga through Mihon and 1080p 60fps YouTube works well on this rom. If you need help, I might be the best person to guide you on the caveats and features of this rom. How can I help?
[Galaxy Tab S Android Development] FrostGalactic:
Is this for the lastest hazou build from october?
[Galaxy Tab S Android Development] saoudien07:
As you, I was enable to install MindTheGapps.

same error "Could not mount /mnt/system"

updater process ended with ERROR: 1

I tried everything, with no luck.

TWRP 3.5.2 or 3.7.0 is the same, no luck.

Gapps is fine.

At start I used Pico, and got error about "Speech Services by Google" keeps stopping", at welcome language selecting in LineageOS after first boot, before to be able to choose language, had to close it. Then set up is ok.

I thought cause Pico doesnt include Speech Function stuffs, so I went again with Micro ( which include Speech stuffs). Same issue at Startup Lineage Inital Language Boot.

So went back with a Fresh start, Stock Rom >> TWRP >> Lineage + Pico , System Reboot.

I am using this a lot, reboot to TWRP & wipe dalvik+cache.

No Speech error this time with Pico.

Rom is working very well, but I experience an reboot issue (long Forever Reboot), and Power also: it stays on Lineage Welcome Screen forever ! I tried to turn Off and power

I go into TWRP, then wipe dalvik+cache, and reboot to System. Sometime it do not work from first try.

It does that like 8 times on 10, stuck on welcome Lineage Screen, really annoying!

I tried Lineage + Gapps only, without Magisk, same issue.

I tried different approch, reinstall the Rom + Gapps, and let it set for 6h to test reboot issue, without any apps or anything, pure Stock Lineage, and same issue with the reboots.

any idea, what can cause that??

Thx
[Galaxy Tab S Android Development] Bosjie:
Try: TWRP >> wipe >> Lineage >> REBOOT AND FINISH INSTALLATION >> REBOOT >> TWRP >> Pico

(I read it was advised to do it this way so I did and been running latest Hazou build without issues)
[Galaxy Tab S Android Development] saoudien07:
So in here, you are pointing the transition between Lineage and Gapps.

Remember back, contrary to what you are saying, they said Gapps of any kind or Patch or any stuffs related to Rom, should be installed straight after the Rom, so here, Lineage and straight Gpps/Pico, no reboot even to TWRP. Maybe Patch can be installed later... thats what I followed.

I did not think about to test only Lineage, without Gpps, I mean here, Long Reboot issue. Then we could reduce to the install way of Gapps/Pico.

So >> Lineage >> Reboot to System (Set up Lightly) >> Reboot to TWRP >> install Pico >> Reboot SYSTEM.

About the Wipe after Stock Rom, during the first TWRP, should I reboot to TWRP before to install Lineage.

I am kind of lost at this point, because straight after the first Wipe, it is even written in Wipe msg, "you need to reboot to TWRP before to be able to use Data". Thats the way, I always used with Custom Rom.

Meaning:

>> Stock ROM >> TWRP >> Wipe Data/Dalvik/Cache >> REBOOT TWRP >> Lineage

or

>> Stock ROM >> TWRP >> Wipe Data/Dalvik/Cache >> Lineage
[Galaxy Tab S Android Development] cicisbeus:
Sorry for my rusty English.

I'm on SM-T800 too.

I have never changed the original resolution of the tablet, which has been working perfectly for several hours now.

This, after the operation on the two "Android Webview" files.

I only have to test Netflix

Update:

also tested Netflix (original apk) and works fine
[Galaxy Tab S Android Development] Samtab800:
ok
[Galaxy Tab S Android Development] sdno:
Does anyone know how to make Netflix works? :(
[Galaxy Tab S Android Development] sirichais:
Just let you know for T705

I try serveral as instruction but boot loop. both of rom.

I come from android 6.x custom rom with full wipe as instruction.

so now flash back as previos rom.
[Galaxy Tab S Android Development] Samtab800:
To use netflix on a rooted tablet you must via

magisk install the liboemcrypto module first otherwise netflix will hang while playing .... Restart and install netflix.
[Galaxy Tab S Android Development] Samtab800:
For sdno

Update for Klimtlte : update some cpu governor (wheatley, conservativex, darkness, intellimm, lionheart) sorry for a long time i'm quite busy on kernel branch and other stuff
[Galaxy Tab S Android Development] pathyas:
This is simply awesome. I really appreciate the efforts Frank.

I have installed clean install crDroid on my SM-T805 but all my apps are closing and freezing randomly. Cleared Cache, restarted several time but no use. Also the Jio (Mobile Data stopped working too) Can any anyone help?
[Galaxy Tab S Android Development] ISoreo:
Update for Klimtwifi build same as klimtlte. I'm build it on my own laptop not server so that take time around 30 min for each boot image
[Galaxy Tab S Android Development] vpn560:
Thanks for brilliant prompt ! I also tried this way. Have tested the latest webview with Virustotal and found a potential bug, so used the ...Dev.apk in system app mode with trichromelibrary.dev.apk. In the {} Developers options switched webview to webview.dev and rebooted. Chrome does works without termination on such pages as our xda thread, but in comparison with LOS 14.1 rather slowly. So returning to use the wonderfull LOS 14.1 yet. Btw it continues to be weekly updated !

P.S. I guess that the reason of slowness is in WebViewDev in the couple with TriChrome lib.

(Tried LOS 17.1, not CRDroid, and no GAPPS on Klimtlte)
[Galaxy Tab S Android Development] lilroach:
Thank you, this helped me get past the logo screen.

I have an SMT 800 and everything seems to be working including the camera, flashlight, and fingerprint sensor. Thank you as you have saved me from having to buy a new tablet for my work.

The only issue I am noticing is that the browser, including on Chrome and on Firefox, crashes regularly.
[Galaxy Tab S Android Development] ruthless10001:
Hi thank you for including klimtwifi but when i try to install your boot image to my t700 it stuck on tab s logo and wont boot. i tried everything i can think of can you explain how can i clean install the rom with your boot and magisk?
[Galaxy Tab S Android Development] mckenzis:
Yes, thanks, @ISoreo but unfortunately I can confirm the same behavior: fails to boot.

My process

Patch supplied boot.img using magisk

Reboot to recovery (TWRP)

Backup existing boot partition

Install patched image to boot partition

Reboot system
[Galaxy Tab S Android Development] ISoreo:
ah okay I think I know what happened, i forgot to edit the config file that switch it back to use another GPU driver let me fix that thing and will release the boot image also I'm apologize that i forgot to check it
[Galaxy Tab S Android Development] ISoreo:
Update for klimtwifi : everything should be fine on this patched, please try it
[Galaxy Tab S Android Development] ruthless10001:
Thank you i will try as soon as possible.
[Galaxy Tab S Android Development] mckenzis:
Thanks @ISoreo. This one boots! Bit early to tell yet so will post again once I have run for a while
[Galaxy Tab S Android Development] ISoreo:
update for Klimtlte : add more cpu governors
[Galaxy Tab S Android Development] Royal Guard 007:
It's great to see that someone is working on the klimtwifi, the boot.img works and I'm excited to follow the development. If someone needs a beta tester for the SM-T700, just shoot me a message.
[Galaxy Tab S Android Development] acytoo:
Flashed the kernel too, booted normally, what's next, or what should I expect? Didn't notice any difference.
[Galaxy Tab S Android Development] Vinchester1986:
Hi, can anyone explain step by step procedure installing boot.img on my Tab S T700?

I have installed Magisk and original LOS 17.1

Edit: patched boot.img via Magisk then flashed it via TWRP. All seems fine. I'll write later about overall experience. Cheers.
[Galaxy Tab S Android Development] ruthless10001:
Hi i also have patched the boot then flash via twrp but oddly it didnt had the root so i flashed the magisk.zip in twrp again and now i have root but i am not sure if the boot.img changes has stuck tablet seems to slow down pretty dramatically actually :S
[Galaxy Tab S Android Development] ISoreo:
update for klimtlte : patched gpu up to 600 MHz from 533 MHz should be more smooth, add more cpu governors, i am trying to figure out about our ZRAM and lowmemorykiller how i can fix this problem
[Galaxy Tab S Android Development] ISoreo:
if the performance is drop flash stock lineage instead, i am do the best on my tab build and test on my own tablet so don't expect much also it's quite slow to build rom or kernel on HDD drive so don't expect much
[Galaxy Tab S Android Development] vpn560:
* Easy way to set SELinux to "enforced" during the boot is to put arbitrary named file with this script:

#!/system/bin/sh

setenforce 1

into /data/adb/post-fs-data.d

After reboot cmd "getenforce" will answer "enforced". No unpacking/repacking of boot.img and usage of init.d is needed.

* New BRAVE browser with Chrome engine and integrated ADBlocker works steadily.

* Local html files for file type links (file:///.../html) must be located in

/storage/emulated/0/Android/data/com.android.chrome (or com.brave.browser)/files/Download/

Now using Klimtlte with LOS 17.1, Android System WebView 92.0.4515.70 beta and no GAPPS.
[Galaxy Tab S Android Development] ruthless10001:
Oh no I wasnt complaining i was just tring to figure out what went wrong :) i really appreciate that you are doing something for us all. Keep up the good work and thank you again..
[Galaxy Tab S Android Development] glennza:
Is there anyone who can port ISoreo's custom kernel over to the T805? I would love to be able to upgrade to a reliable LineageOS 17.1
[Galaxy Tab S Android Development] cicisbeus:
Update:

1) I had deactivated the "Android System WebView.apk" system app and installed the latest version of the same app from Google Play;

2) The tablet worked for a while without crashing Chrome and other apps, then, sporadically, the apps started closing themselves again;

3) I noticed that despite deactivating "Android System WebView.apk" somehow continued to work (?!?). In fact, examining the occupied memory and the cache, they continued to gradually increase.

4) I downloaded the file of the latest version of "Android System WebView.apk" on external sd, without installing it. Then with Xplorer file manager (with root functions enabled) I deleted the system version of "Android System WebView.apk" which is located in the root in a subfolder of "product" along with 2 other subfolders. I also had to delete the 2 subfolders (which contained .odex files of the deleted app.

5) So, always with Xplorer file manager I copied the latest downloaded new version of "Android System WebView.apk".

................................

After restarting the system, the new version of "Android System WebView.apk" has been installed and all apps that require it (for example: Amazon) are working normally.

After an hour of work by opening Chrome, Gallery, Amazon, camera, ... everything works without crashing
[Galaxy Tab S Android Development] ISoreo:
here you are please try it, and give the result back also backup stock boot image first before try it, if the performance get worse please revert to stock
[Galaxy Tab S Android Development] vasid:
thanks for the best rom only jio not working any cure please help
[Galaxy Tab S Android Development] cicisbeus:
Summing up:

1) The problem of Chrome, Gallery, Camera crashes, ... is due to a known bug of the system app "Android System WebView.apk".

2) To solve it, replace the old system app with the new one in the Google Play Store.

I repeat that the system application must be replaced and to do so, the method I used a few posts above works.

After several hours, I no longer have any crashes on Sm T800.

The resolution remained the native one.

Edit:

Also Netflix works perfectly after flashing libemocrypto with magisk

New edit:

Now Lineage is very very fast and without bugs
[Galaxy Tab S Android Development] just_nos:
Mmmm no matter what im doing the rom wont boot at all :)

from ressurected to crdroid or lineage = no go

from stock 6.01 = no go

Always stuck on logo ( crdroid or linageos)

t700
[Galaxy Tab S Android Development] cicisbeus:
Wipe about Advanced wipes: data, system and cache (also dalvik/art).

Flash ROM and stop. Reboot into system.

2 minutes and new system go.

Reboot into recovery (last Twrp) and flash gapps
[Galaxy Tab S Android Development] just_nos:
but wiping system is removing stock rom instead of installing rom on top off it ? right

Weird , i did a flash over the same flash but then adden gapps pico and now its working
[Galaxy Tab S Android Development] cicisbeus:
"Gapps" are causes of many problems in this ROM.

Look at my posts if you have problems with closing apps
[Galaxy Tab S Android Development] tony9527:
Hi

My device is T805

I flicked in and couldn’t enter the system

I had to go back to the original file
[Galaxy Tab S Android Development] mckenzis:
@ISoreo So, it is definitely more stable. Thank you. Not flawless but much more stable.

Haven't gotten to use tablet as much last few days so will continue monitoring
[Galaxy Tab S Android Development] ISoreo:
i will looking in ram management and try to do the best on my own tab s first
[Galaxy Tab S Android Development] AndromedaTR:
Thanks for your work. My SM-T800 (chagallwifi) did not boot after installing openGapps Android 10 ARM. How Can I solve it? It happens only when I installed OpenGapps
[Galaxy Tab S Android Development] cicisbeus:
Gapps are Lineage's Achilles heel.

Download the smallest package (nano or pico).

From TWRP, wipe and install gapps.

New wipe and Reboot in system.

Lineage should start.

You'll then have problems with sudden closure of Chrome and other apps: read previous posts
[Galaxy Tab S Android Development] Numansheikh:
Thanks for this Rom .. Everything is working but Sometimes apps crashes .... can you please solve this or can you please make Android 11 for this tablet .. SM T705
[Galaxy Tab S Android Development] MZWiZard:
When I try to install this image through twrp, the t805 fails to boot.
[Galaxy Tab S Android Development] glennza:
I can confirm that this boot.img causes the T805 to hang on the first screen. Clean install, booted once without problems, installed boot.img and hangs!
[Galaxy Tab S Android Development] ISoreo:
OK i think i was know what happened i will build the new one of boot image
[Galaxy Tab S Android Development] ISoreo:
please try it, always backup bootimage first also i apologize that i forgot to switch to another gpu that cause stuck on boot logo mine was happened too
[Galaxy Tab S Android Development] glennza:
Sorry, still hangs on first screen!
[Galaxy Tab S Android Development] ISoreo:
ah please use stock instead for a while i don't know what happen
[Galaxy Tab S Android Development] cicisbeus:
With T800 and T805 you can safely use stock boot.

All the problems of apps that close on their own, can be solved by replacing the system apk "android system webview" as explained in previous posts.
[Galaxy Tab S Android Development] steamrollerpark:
Thank you so much for this Rom! Working brilliantly on SM T700.

Flash the rom, boot up.....and then go back and flash Gapps.

Have not tried Magisk yet, but quite happy with it even without root.
[Galaxy Tab S Android Development] vyper29:
Great ROM and thanks for this advice. What version of Android System WebView is working for you? I followed your steps and replaced mine with version 91.0.4472.120 (latest). Chrome still crashes often.
[Galaxy Tab S Android Development] MZWiZard:
Tonight I just compared this rom to a 7.1.2 rom. It was at least 50% faster than this, both at installing apps and screen smoothness. Has anyone figured why this one is sluggish?
[Galaxy Tab S Android Development] Bushcrafter:
Thanks for the ROM! It brings new life to my T-800. Congrats to all the Devs for making this ROM possible! 👊
[Galaxy Tab S Android Development] cicisbeus:
With version 91 .... of "Android Sistem WebView" there are still some sporadic closing of Chrome, as the cache grows.

Version 92 .. beta seems to be doing better
[Galaxy Tab S Android Development] cicisbeus:
The tablet works well, all apps run smoothly (even Netflix).

But sometimes, there are still sporadic chrome shutdowns (especially when I try to open images from the web on the same page, if I open the images on a new page instead, this does not happen).

There is still a test to be done, as soon as I have time, I will replace webview with an old version earlier than those that cause crashes

Update:

1) uninstalled all previous WebView and removed their traces;

2) installed WebView version 89.0.4389 ... (as in the figure) and restarted the system;

3) uninstalled Chrome (the only app that refused to work). Restarted the system again and then reinstalled Chrome from the Play Store.

Now Chrome works without crashing and I can even view images on the same page (which was impossible before).
[Galaxy Tab S Android Development] aljoscha81:
please can you send link for apk i am at the moment with my friend will have the fix ;)
[Galaxy Tab S Android Development] cicisbeus:
I find everything on APKMirror
[Galaxy Tab S Android Development] maxq1:
i was able to install webview via playstore on a t700 with this rom freshly installed. didn't uninstall anything. fwiw, i used open_gapps-arm-10.0-pico-20210529. weird though coz on my previous installation with this rom and my sd card partitioned for both internal and adoptable, can't install it even with the suggested methods. i suspect it's coz install was defaulting to adoptable
[Galaxy Tab S Android Development] ISoreo:
update from klimtlte : i think i do much on memory manager, app should not crash while open youtube alongside with browser but you will see launcher refresh itself due to lowmemorykiller kill it i think. btw, i'm running on this boot image for a while and always please backup boot image first before flash this rom
[Galaxy Tab S Android Development] MZWiZard:
Can you list the changes you have made - and will you do them for t805 as well? :)
[Galaxy Tab S Android Development] hippo2s:
Currently on LineageOS 14.1 (Android 7.1.2) for years. Wanted to upgrade with this rom.

I didn't re-flash with Samsung firmware - instead did Data wipe in TWRP, and tried to install this ROM and got a

E:unknown command [log]

Updater process ended with ERROR: 7

Error installing zip file...blah

Any ideas? other than going back to samsung firmware with ODIN?
[Galaxy Tab S Android Development] ISoreo:
I am not sure i can do it or not because most of all on sm-t805 they cant booting up, they told me it freeze on boot screen, mine on sm-t705 that one freeze too but take sometime to booting up around 5-7 seconds
[Galaxy Tab S Android Development] cicisbeus:
@ hippo2s

Wipe about Advanced wipes: data, system and cache (also dalvik/art).

Flash ROM and stop. Reboot into system.

2 minutes and new system go.

Reboot into recovery (last Twrp) and flash gapps
[Galaxy Tab S Android Development] hippo2s:
Didn't work.

After flash ROM and reboot into system.....

Now stuck on start up Samsung Galaxy Tab S logo screen. LOL Tried to hard reset it, still on startup logo.

Time to ODIN i guess...
[Galaxy Tab S Android Development] cicisbeus:
If I have understood correctly, the reboot remains on the Samsung logo and, therefore, does not load Lineage OS (lineage logo does not appear).

If so, I think you don't have the right version for your Lineage OS tablet.
