You need to flash the rom first, then magisk 19.1 - I would suggest the cannery build for the manager, ( you can just uninstall the one that comes with the zip, and install the cannery apk) you also have to flash gapps 10, or you will not boot properly; I would also suggest flashing the dm verity encryption enabler ( It came back on for me, better safe than sorry). After that you should be good.

Rom --> magisk 19.1 --> gapps --> dm verity --> reboot.

If you don't have those files, - remember, you have otg as an option, you sd card, and usb debugging. If anything goes bad, just format the data, advance wipe, and you should be good to go!

I saw a post stating that if you have magisk installed you can go to your terminal emulator to be able to edit the build prop. You would have to type " 'su' then 'setprop' following with your command without an equal sign. (so a space where that would be) ... You should be able to write anything to the build prop; now I'm on Q like everyone else, and my goal for this glitch of a rom , is to at least get on screen Navbars on my tablet (smt820). I know Q is read only, but I'm desperate, guys.

Has ANYONE been able to figure this out?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Veritas06:
Thanks, I'll give that a shot. I'm hoping to avoid installing GApps at all, would rather just work with Magisk & Nanodroid\FDroid for apps. Will play around with it again & see if I get lucky by flashing in the same session. I've been trying to pretty much flash one ZIP, reboot, back to recovery to flash the next... Fun times ;)

Pie bootloader

I had this same problem until I went to sammobile and downloaded the latest firmware files and then flashed the pie bootloader with odin. I actually flashed all the files with odin going back to stock first and then OEM unlocked the bootloader, reflashed twrp with odin and flashed the February build and it worked finally. I don't know if you need to flash all the files and go back to stock first like I did or if the bootloader alone is enough but this did the trick for me.

---------- Post added at 01:32 AM ---------- Previous post was at 01:27 AM ----------

I had this problem as well. I downloaded the firmware files for stock from sammobile and then flashed them with odin to fix this. I then re OEM unlocked the bootloader, reflashed twrp and then flashed this rom and the screen rotation worked fine.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Veritas06:
Thanks, I'm going to try that. When I ran getprop from TWRP, I think I'm seeing some Oreo or earlier entries for the bootloader, so hopefully upgrading at least that part to Pie will fix this for me.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] reductoexpulso:
Hope it works out!

A few problems

I installed this firmware on my wi fi version and now I have encountered a couple of problems:

1.When I start using the microphone everything hangs and I have to restart the device

2. Has anyone tried to fix a problem with the speakers?

Hi Only Malinka. thanks for your advice. I followed it exactly and after I loose my data (which is normal) and reboot I have to fill in all information again. After that I reboot to TWRP and again data partition cannot be reached. 0 mb..https://cdn-cf-3.xda-developers.com/images/smilies/frown.gif

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] VVombat:
You have to format DATA in TWRP, flash LineageOS, and then reboot as stated in this thread. This worked for me.

Nvm, tried different approaches and none of them worked for me. Anybody else has an idea?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] VVombat:
On a side note: This is definitely wrong. I'm using this ROM without gapps.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] myfishbear:
i had the same problem, all i had to do was wipe all the partitions in twrp, reboot into twrp and install my zips from the sdcard rather than internal storage.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] BrMBr:
Thanks for the dev's effort. To those criticizing, his job is for free and no complaints are acceptable as the risk is all yours.

Despite that, this build is kinda crap. No mic, no palm rejection, terrible camera, many bugs and crashes. Tab S3 proved to be the biggest piece of S**** tablet of all times. It's difficult to implement any custom roms. Tab S2, S4, S5, S6 are way easier.

My advice: go back to stock rom, root, debloat and be happy. If you wanna do so, start here.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Neo3D:

Hi, I´m on #1 can I just flash #3 directly (dirty flash) to update or should I do a clean flash (after a complete wipe)?

Is it right to jump directly from #1 to #3?

Thanks in advance

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] elreymon:
Yes
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Neo3D:
It is much quicker, but I have 2 issues:

Very unstable, every 30 secs or so, it slows down to a crawl and have to do a force reboot.

Can't install Netflix on it, tried every workaround I could find, nothing worked.

I've reflashed this about 8 times, similar results every time, what's your experience?

MicroSD works fine for me, here's how I flash:

[Power] + [Vol Up] + [Home] to go into TWRP

Go into wipe menu and format user data

Power off the tablet

Go back into TWRP again

Wipe the entire thing except microSD

Flash lineage-17.1-20200211-UNOFFICIAL-gts3lwifi

Flash open_gapps-arm64-10.0-nano-20200325.zip

Flash Magisk-v20.4.zip

I use Samsung brand microSD. LineageOS can use it as either portable or internal storage, but neither improve this ROM's stability.

---------- Post added at 07:40 AM ---------- Previous post was at 07:34 AM ----------

After having (tried to but really couldn't because it froze every 30 seconds) used this ROM for a week and reflashing it 8 times, I have to agree 100%.

People who got this to work stable, how did you pull it off? Step by step please?

How long can you use your tablet with a different launcher before it freezes?

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] KeepingItCuttingEdge:
Dead?

So is this attempt basically a no-go for now? I just got one of these because of the screen aspect ratio being 4:3 and AMOLED. Was hoping to put Lineage on it like I have working wonderfully on my Tab S2 (also 4:3 and beautiful AMOLED display). Not everyone watches movies on tablets and the 16:9 is just cumbersome and pointless for non-movie browsing.

For those who haven't purchased and are considering, the screen is GREAT and beautiful on these. Wonderful sound. But stock firmware is SLOW. It's fine to browse FB and send messages.

Just my two cents worth FYI. :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] piero60:
Does google assistant work in this rom?is there any way to make Bixby work?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Pact:
Can someone who uses the pen, explain in detail on the palm rejection issue? Say you were drawing a straight line, then your skin touches the screen, what happens then? Is the line disrupted/ink stops flowing out?

Also, assuming you manage to not touch the screen while using the pen, does it otherwise work fine? Pen pressure, pen button, cursor etc

Someone earlier in the thread said they're fine with all the issues since they're just using it as a book reader device; my usage is nearly similar too but I use the pen actively. If the pen works fine aside from the skin rejection issue, I might try to write from the shoulders lol.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] schmolch:
None of that will work.

I don't use the pen either but the horrible battery-life and only half of the speakers working made me switch back to the tweaked stock rom, which actually runs pretty well once you remove all the Samsung crap.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] coolguy001:
thanks for the rom. any plan to update this rom monthly?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Edmondo Occhipinti:
It takes a lot of time to boot for the first time, is it normal?

Surely it's booting for at least 30minutes. Does it take 1 hour? My other modded devices with Los take so much less. Maybe it is the device, not the rom.

The device is really hot and the Los logo began to lag.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] JordanBleu:
Hmm, that looks like you had a big bootloop...

I didn't find anything on forums and YouTube, but I guess you should press volume up, down, home button and power button simultaneously until it reboots.

And after it reboots, try very fast and press volume up, home button and power to enter to TWRP and flash the ROM again.

My advice is that instead you flash OpenGapps, which are full of bugs on the Android 10 version, flash NikGapps.

If you enter again to a bootloop, go to TWRP and wipe Dalvik/Cache.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] JordanBleu:
Hi ! Will this rom be updated someday ? It's almost three months since you uploaded the February version....

You are not forced to do it, it's not in your obligation, but there are people like me who are frustrated with this complicated tablet, and want a recent ROM which works entirely (and not only to read ebooks).

Is it possible to solve the speaker problem and the palm rejection ? Also, it would be great if you include April or May security patches.

And maybe a newer Kernel ? Please, all your ROMs are great, and I think it's not fair that while your midrange tablets like the A series got the newest version of LOS 17.1 with Kernel 5.0 and up, this beautiful and expensive top tablet that is the Tab S3 is being abandoned.

Samsung abandoned it, I agree even if it's not fair, but please keep on supporting the Tab S3.

Thank you, Valera.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] myfishbear:
Love the rom so far! thank you for your work!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] andoyskee:
does the 4 speaker now works?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] JordanBleu:
It seems like not.

I advise you to "trebelice" your Tab S3 if you really want a good ROM instead of this, at least with GSIs almost all seems to work.

Anyway this LineageOS will never be updated, because suddenly Valera abandoned the Tab S3 on the profit of the Tab A series, so don't expect a lot about this guy...

It's better a good GSI that at least will be updated, than an outdated and unofficial thing that is this ****ty ROM.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] andoyskee:
what does it mean by trebelice? Any ROM you could recommed for T820? I am currently looking for something that has the 4 speakers and adoptable storage working.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] giannisk:
Do you propose something in particular ?

I have a T825 that want to speed up, cause samy's rom is slower than turtle

Thanks
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] JordanBleu:
"Trebelice" is a way to say that you make this device compatible with Treble, since by default it's not compatible, and with this you can put any ROM that is compatible with Treble GSIs.

Try with this and read it carefully (only the firmware and TWRP for your version) : https://xdaforums.com/galaxy-tab-s3/development/project-treble-based-android-9-0-t3918235

The ROM that I think will work is Havoc OS 3.4 Official GSI, here : https://sourceforge.net/projects/havoc-os/files/arm64-aonly/

Be carefully and select only "ARM64 A-only" otherwise it won't work.

In this link, there are two versions, the version without gapps and the version with gapps ; if you want something that fully works, I recommend you to select the gapps version.

I hope that it will work for you, and please tell me your experience after flashing it.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] andoyskee:
I flashed the custom TWRP using odin and using stock Oreo. I have followed the instructions and got an error installing the treble-16.0.zip.

Then I get a bootloop after installing Havoc image and reboot to system. Did I do something wrong?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] JordanBleu:
Hi.

If you don't know how to Treble, please read the other post I posted.

For GSI, I highly recommend Offical HavocOS 3.4, with gapps.

Here's the link : https://sourceforge.net/projects/havoc-os/files/arm64-aonly/

If you want that I will fill work at 99%, flash with the gapps prebuilt option.

Please tell me if this works and if Netflix works at Full HD, because that's why I still didn't put any ROM on mine.

---------- Post added at 03:40 PM ---------- Previous post was at 03:36 PM ----------

Yes : the link I posted was if you had the PIE firmware and bootloader on your Tab S3, so obviously it didn't work for you...

Instead of panicking, flash with Odin the latest version of your firmware you can find on Sammobile (logically this time Pie) and retry.

I'm so sorry I didn't specify if it works with the Oreo or Pie bootloader, I thought all people had Pie. I'm a big dumbass .

Please tell me if this time it works, I also want to test it on my Tab S3 (T825).
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] giannisk:
Thanks, i will try to treble.

But at first i want to find a pretty stable custom rom to have base and backup for anything wrong.

Do you have any clue on this ?

Right now i just installed twrp 3.2.1-1 i found in other thread.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] JordanBleu:
Did you installed the Treble TWRP ? Otherwise none of any GSI will work.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] giannisk:
No. The treble twrp works as the non-treble ?

Do you know a stable custom rom non-treble ?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] JordanBleu:
Treble TWRP that Valera made allows to flash GSI images and non GSI , without any complication and problem.

A stable ROM without Treble is impossible for this tablet, since the the only rom we have for the Tab S3 is this LineageOS 17.1 which is totally outdated and plenty of bugs :(.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] andoyskee:
Hi Jordan,

Here are the steps I did

1. Flash stock Pie firmware using odin 3.14.4

2. create a .tar version of the custom twrp recovery.img

3. flash custom twrp.zip "AP" using odin odin 3.14.4

4. boot to recovery

5. install treble-16.0.zip.

I still get the same error

Target: ...

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] JordanBleu:

Can you try this other one ? It's Descendant X https://downloads.descendant.me/

It's our last chance, so please try again and sorry for all.

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] JordanBleu:
Thanks for telling me your experience and I'm so sorry...

If you only can put Pie ROMs in this case is better to keep the original firmware, which totally works.

It showed us that not only this tablet is a big piece of ****, but that developers for this tablet doesn't exist, and the only one who "maintains" this tablet is incapacitated to make proper ROMs.... We are so lucky...

On the site they have several versions but I cant figure the correct one for this device (that appply for both; Havoc and Descendant).

Thanks
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] JordanBleu:
Hi!.

If you already "trebelice" your tab (making it compatible with Treble and these ROMs) you have to search for ARM64 A-Only ROMs, otherwise it won't work.

But if you can I'll suggest you to wait until tomorrow, because I'm testing a ROM I ported to the Tab S3 (both T820 and T825) and it's Evolution X 4.4.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Alex20137:
OK so in 2020 what is not working and is it stable?

I think I'll install it as my daily driver
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] JordanBleu:
What doesn't work:

- Screen rotating

- 4 speakers (only 2)

- Dolby Atmos

- Camera is buggy

- The pen isn't recognized and doesn't have palm rejection

- The ROM itself isn't very stable (from what other people said, sometimes it even bootloops)

What works :

Almost everything else (but I'm not very sure).

But, consider that this ROM is already abandoned (even OP doesn't update it, the latest update being from February....)

If you want some good and stable ROMs, I highly recommend you the Tweaked ROMs, they're stock roms, but highly debloated and deknoxed, and it works pretty fast on my Tab S3.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Alex20137:

Hi,

if there any chance for a new release of a kernel? The current one dated from February 2020.
