Bought you a small 10$ coffee via paypal for more tab s3 t825 lineage updates, cheers!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Say_YO:
Hi,

I can confirm that this was the only method that worked for me, had a lot to do, had to instal stock FW first, then Clean instal 19.1 and then dirty 20.

Works fine until now.

Thx
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Say_YO:
Some other thing...

i flashed TWRP 3.6.0_9.0 as Recovery, and every time i want to get to it, it gets stuck, restart or wenn the Tablet it's shut down, so i always go into download mode, flash it again and then i get to get in the Recovery, is it only me or am i doing something wrong?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bouuman:
had same here with lineage 19.1

if i want to go back to twrp then i have to flash it again via odin

after first reboot its gone

since 19.1 -> dirty flash 20.0 , i can start twrp normal via tablet reboot and power+volUP
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] vonschau:
Send an other 15€. Hope it helps for a new device😉
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Finally I got a new one. Will upload the new version soon.

Thank you all for supporting me! :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] geopapa:
Can anyone confirm if Disney+ works with this ROM? It doesn't work on Lineage 19.1 (it works for a while and then it crashes when a video is loaded).
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] hamletiano01:
Thank you Awesometic for your work.

Just discovered this ROM as bought the tablet a few days ago.

1- Volume in earphones is way too low compared to Android 10 -if I'm not wrong this is something present since Android 12, but does somebody have any tip? I use the tablet for drumming and can barely listen the music in the background...

2- Reading the known issues - any hope the microphone will ever work on videocalls?

Again, thank you for your dedication.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
To fix the Bluetooth earphones working (and more that I don't remember), I changed it to build audio HAL from the source. Before that, we're using the prebuilt audio HAL from the OTA firmware.

This makes us use the main features of the Android audio system, but at the same time it also breaks some tunes like volume or some features such as voice calling since we can't use the same configuration file that in the firmware. We need to re-write that file to use all the audio scenarios flawlessly..

Consequently, the audio issues like volume and voice calling are caused by moving from the prebuilt file to the built one, and I need to find the correct line and name, and the value in that config file to fix them.

Yeah, I wrote this to inform for those who wonder why the audio has been broken since Android 12. 😅
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] hamletiano01:
Thank you very much for your explanation.

In my noob understanding... Does this mean that eventually both issues could be fixed? Because that would be just AMAZING!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Hopefully, as Android 11 (LineageOS 18.1) could do.

But don't expect too much 🙈 I'm going to try my best, but still there is a possibility that I couldn't fix them.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] hamletiano01:
Of course won't blame you if you can't, but got my faith in you after seeing your work! Can't really help you with anything technical besides testing builds if that helps you on anything... Thanks again!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] eossam:
@Awesometic, the Calxy-Team had the same problem (LTE not working) when migrating to CalyxOS 4.2 > CalyxOS 4.2.7 (Android 13). They were able to solve it with the help of LineageOS and PixelExperience.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Thank you for the information. It seems like the patch is already on the LineageOS side then.

Currently I'm working on fixing the boot loop problem with TWRP Android-9.0 build. From my understanding, it should not be stuck even if there is no support for FBE. It seems something unsupported thing is there in our device tree. I doubt that is mdfpp Keymaster thing for now..
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Edmondo Occhipinti:
unfortunately bootloop (twrp, android 12, crdroid) at first boot after instructions :(

will wait for next revision
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] MachineMasher:
Are you getting the boot loop with just the LineageOS ROM? Or did you try to put GApps of some kind with it?

I've often found it to be kind of finicky to make it work with GApps (sometimes requiring that I modify the GApps ROM to resolve), but I've never encountered a boot loop with just LineageOS on its own.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Edmondo Occhipinti:
the first time i tried with gapps. Then i formatted everything again and tried without them. Unfortunately, same problem
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] chrysopra:
So far, dirty flashing over 19 seems to be the best workaround, when you encounter a bootloop. I believe, Awesometic is working hard to enhance the stability of this ROM. Unfortunately, that's not an easy job, and he seems to be quite alone in maintaining the S3.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Thank you all for understanding. It is right, I'm trying hard to fix the boot loop problem, which is the top priority at this moment.

I tried many cases about encryption and keymaster thing, but nothing has succeeded yet. 🙈

Wokring on both LineageOS system and TWRP.

After a few more shots, I think I may need to leave it as broken, and need to write installation instructions about that workaround for using Android 13 ROM.

Currently dirty-flashing from LineageOS 19.1 is the best workaround. Sorry for this inconvenience.

Plus, I think I can upload CrDroid 9 ROM too. I built one, and will test it tomorrow with CrDroid 8 for the dirty flashing. It is too late today :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] chrysopra:
Coming from stock, I first started with TWRP 3.6.x which refused to start. Reflashing with 3.2.x solved the problem. As far as I remember then I flashed first successfully again the 3.6 followed by the Lineage 20 with no bootloop. Maybe there are files or structures which the older versions have and the newer ones not? Therefore a dirty flashing keeps some essential data, which are not included in the newer versions??
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] eossam:
@Awesometic, yes, please do it!

Official crDroid ROM supports signature spoofing. Will your UNOFFICIAL crDroid 9 ROM support the installation of MicroG?

Signature spoofing support for your LineageOS 20.0 ROM would also be a nice addition for all users who don't want to install NikGapps or other GApps.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] gukovsem:
Very nice Rom, thank you for your work, tablet got new life. Installed dirty over Android 12. Used twrp 3.7.0_9. Waiting fix for microphone.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] hamletiano01:
Definitely, hopefully @Awesometic is able to fix the audio/microphone thing because this tablet would have reborn. :love:
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] MachineMasher:
Just wondering...there are a few apps that don't list in the Play store that I know for sure are compatible with the device because they are there for other Android 12 devices and they also work fine when sideloaded. Thinking it's because the app creator lists it as requiring a stock rom (it also didn't show up on Awesomtic's Android 11 or 10 ROM either).

Would installing Magisk make the ROMs show up in the play store (I've never used Magisk before)? Is there any other trick that I could use to make the apps show up?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Sage:
Great work! Can't wait to see this progress!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] EthanCrane22:
Since this ROM is not play protect certified, a lot of different apps won't appear in the play store. The only way around that is either to use magisk and spoof your device signature to a device that is play protect certified. Or to do what I do and just sideload the apps you'd like! I've attached a couple photos showing that the ROM is not play protect certified.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] paul_ramone:
Thanks a lot, Awesometic!! I installed the ROM without any problems. The tablet looks like new again! Wonderful job!

The only thing I was not able to do was to encrypt the tablet. I am not sure if I am doing something wrong. If I go to "Encryption and credentials" and click on "Encrypt tablet" (not sure if this is the text in English, because I use a different language), nothing happens.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Helg.es:
I have two tab s3s, first i had both on 12l, and now one on this one.

Problem is,they both get the same Mac address with these roms.

Both ending in 5c:d8.

Any way to fix this?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] 908070:
Same here (...5c:d8). It's normal?

Shouldn't the mac address come from the hardware?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] EthanCrane22:
Typically, the MAC address

is

based on the hardware, you are correct.

Android has a built in feature called "MAC address randomisation" that changes the MAC address anytime you connect to a network for security. In this ROM however, the option to enable randomisation is actually missing... I was able to find the developer option to "enhance" how random it's pick is but it doesn't appear to work.

It looks like from what I've read online it's apparently "device specific" for MAC randomisation so it might be something Awesometic could enable or implement into this ROM and fix those issues!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Hello all, it's been a long time.

Last few months, I tried to fix the boot-loop problem first but I couldn't succeed. 😓

So for now I give up to fix that, and I will look into fixing the existing problems first such as the audio one.

I uploaded the new LineageOS 20 ROMs, which are synced with the latest LineageOS source codes.

Please see the new instructions too for clean installation.

# How to install

To fix the boot-loop problem, we need to install the previous custom ROM at least once.

Unlock the bootloader.
Download TWRP and flash the recovery image via Odin.
Download any Android 11/12 based custom ROM, such as LineageOS 19.1 for Galaxy Tab S3.
Download LineageOS 20.0 for Galaxy Tab S3.
Be aware of the board name.
Download GAPPS for Android 13 and the others you want to flash.
Enter TWRP recovery.
The first boot to TWRP might be very slow because of the unmatched file systems.
Format the whole system, data, cache partitions using the format menu.
You will type `yes` to do that.
Install Android 11/12 based custom ROM, such as LineageOS 19.1.
Boot once, and if the initial setup screen appears then reboot and enter the TWRP again.
Erase the partitions using the advanced wipe option.
It'd be the system, data, caches, and internal storage.
Flash the images, including LineageOS 20.
If you're going to install GApps or something, you have to install the LineageOS first.
Reboot the system.
Done.

The point is, if you have installed my Android 11 or 12 based custom ROMs at least once and haven't formatted the partitions using TWRP's format menu, you can install the Android 13 base custom ROMs only with wiping system, data, caches, and internal storage partitions using advanced wipe menu in TWRP.

And, I will upload CrDroid 9 soon.

PS. Keep in mind that you should make a backup of the current system/data partitions before updating. It's on the ALPHA stage yet.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] MachineMasher:
Wiped my SM-820 device that had the previous Awesometic's previous LineageOS 20 image on it and successfully clean installed lineage-20.0-20230102-UNOFFICIAL-gts3lwifi.zip with NikGapps-core-arm64-13-20220908-signed.zip WITHOUT a reboot between them. I didn't have to modify either ZIP file at all.

As far as I can tell, everything is working except for the known issues of the green bar and inability to use mic or speakers in Zoom or other call apps.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] mmcfly42:
Which version of TWRP did you use for a clean install without going through 19.1 + a dirty flash of 20 ?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] MachineMasher:
The old twrp-3.6.0_9-0-gts3lwifi.img.tar one that Awesometic had posted before the most recent update.

I think it's worth mentioning that the tablet has, in the past, had Awesometic's 19.1 ROM installed on it, and I wiped rather than formatting the tablet using TWRP. It might be because of that that it worked without getting the boot loop issue.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] jpmartinho78:
Hi everyone. Just gave some more life to my tab S3 and still testing but have some gripes.

It seems I lost the button on the left of the HOME button;

Pixel launcher keeps crashing;

Can´t work with the original Samsung keyboard cover.

Advice?

Thanks and very good job on this ROM.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
@Awesometic flashed today ontop of your LOS19.1.

First I flashed your TWRP 3.7.. hoping it would recognise the size of "System" as less than 2GB what it said on TWRP 3.6.0.. but it shows the same size. Don't believe it's really that big.

Wiped only what you wrote so I kept Data.

Flashed ROM, Magisk, NikGapps64.

Booted fast and all apps/widgets showed up and seem to work.

Nova prime, google account, fairemail aso.

BUT it's not only "no LTE" as quoted in #1 as it's NO mobile connection at all not even 2G. "Emergency calls only" it says.

Did I overlook that in the thread?

When testing @phovals LOS 20 version for my T325 it took a lot of logs from my side and a lot of brain and time on his 'till he got it working.

SIM worked on 19.1 T825 btw.

Fun fact: Signal messenger doesn't notice missing SIM as it's working in Wifi mode like before.

Thanks very much for your work.

Edit one day later 2 things:

1 When device rests for some time (~1h or more) fingerprints doesn't work as it tells me that after reboot (which I didn't) only PIN will unlock the screen.

2 After an even longer time WLAN connects to router but T825 tells me no Internet (Wifi Logo +!) only system reboot helps. (no matter if I shut off Wlan before or not)

Really peculiar behaviour that today 7h after the edit both m. a. didn't occur.

Logs available after reboot and when not reconnecting.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Manlycookiebear:
Wonderful ROM, thanks a lot for your work!

I have just one question. Is it possible to get rid of the software navigation buttons in the lower part of the screen? I already disabled the option in the settings, but that does not get rid of the buttons.

Something seems to go to sleep really that deep when letting it rest for some hours.

Then it connects to router but no internet connection possible until after reboot.

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] MachineMasher:
At this point, we're pretty close to the release date of the next Android security fix, so it would probably make more sense to wait for that and get it included in the next update rather than rushing one out now.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] 7ftPhil:
Same experience for me.

Enabling Wifi Scanning has made this happen less often, but it still happens.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] 7ftPhil:
@bmwdroid - this works for me:

Set tablet to Airplane mode

Reboot

Disable Airplane mode

Connectivity now works until next reboot.

Please let me know if you experience same.

I'm not able to turn off the taskbar on the current ROM version. I installed this ROM today, after previously using the v19 ROM. I didn't have any difficulties turning it off with that ROM.

Here's a screenshot of the buttons settings. As far as i can tell, the taskbar should be turned off, but as you can see the taskbar is still present in the screenshot.

Any thoughts as to what is wrong here?

Thanks!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] gerega:
So sad! Managed to install the latest ROM smoothly. I then put my SIM-card into the tablet, but it wasnt recognized. I tried to set to factory defaults, but nothing happened. Then I tried to start TWRP again. Since then the TabS3 is stuck in TWRP on splash screen. I can turn it off, install the TWRP again, but it still hangs on splash screen. Even when I install v3.2.1 from another thread.

Seems like it is bricked now.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
Had nearly the same problem after noticing that I can not miss LTE.

TWRP hang and flashing earlier ones didn't help either.

Had to go back via Odin flashing multiple part stock ROM.

Startet without SIM or Wlan so it didn't know date and time.

OEM unlock appeared after rebooting with SIM card and then I flashed TWRP again and later 19.1.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
@gerega btw. as it's mentioned in #1 LTE isn't working anyhow
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
I experienced the same before I returned to 19.1 again which was quite a hazzle as I had to start from scratch.

Don't wanna miss LTE and camera as it's my main tablet atm.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] gerega:
Thank you so much! I was afraid that it will end like this. Damn! But at least I know that it will work this way. Many thanks to you... and awesometic for his work!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] gerega:
I have really read everything and have hoped that LTE wont work but maybe 3g and 2g would do it.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
afaik 2+3G are turned off or going to be in most countries.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] gerega:

Everything seems to be working except for the known issues with the green bar in Zoom and the fact that the mic and sound both don't work in Zoom either.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] kotoy1982:
I have recently installed the latest version (2023.2.13) and my tab s3 has never been smoother, thanks to Awesometic's work. There is only one problem and I would like to ask for your help.

The details are as follows:

When the screen is switched off (e.g. left idle for a minute), there is a certain chance that the system will reboot (LineageOS logo animation). After that reboot, the wifi function does not work and the system often stops responding, and only after a manual reboot does it return to normal.

Thank you very much!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] MachineMasher:
This is strange - I've seen others report the same thing, but haven't encountered it myself at all.

Just wondering: are you using an SM-820, or an SM-825? I'm using an SM-820, so am wondering whether maybe this only happens on the 825.

EDIT: I have now reproduced the issue per this post: https://xdaforums.com/t/rom-unofficial-alpha-13-eas-sm-t820-sm-t825-2023-2-13-lineageos-20-0-for-galaxy-tab-s3.4510785/post-88191063
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Giasko:
I have also experienced this issue on my T825, but managed to narrow down the issue to it. For me, the problem occurs only when I bring the S-Pen near the screen and then lock the tablet. The tablet doesn't do a full reboot, just the LineageOS logo, and then the wifi stops working until next reboot.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] MachineMasher:
Wow! You're right, I tried doing exactly what you said on my SM-820 and encountered the problem for the first time!

The S-Pen doesn't have to be close to the screen at the time the tablet is locked; I can pull the S-Pen away and wait 30 seconds and the issue will still happen.

I guess I just almost never use the S-Pen, so I don't encounter the issue.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] retiredtab:
@Giasko @MachineMasher , it would help the developer if you can easily reproduce this and get a logcat which you can then attached as a zipped file (text files don't seem to get attached properly).

# clear the logcat first
adb logcat -c
# start logcat trace
adb logcat > problem.txt
# reproduce problem
# wait until problem has occurred,
# then stop trace by hitting ctrl-c then zip the problem.txt file
# before uploading it.

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] kotoy1982:
@Giasko @MachineMasher @retiredtab

Thank you for your replies, I hope this problem has a chance to be solved.

My device is T820, I have found a process that can trigger the bug 100% on my device, maybe you can try it.

1. completely shut down and restart. (Away from the s pen)

2. After entering the system, *finger only* , repeate opening app, turning off the screen, turning on the screen, opening another app ...... everything is fine.

3. Pick up the s pen and do any operation on the screen. (like draw a circle in the note app)

4. Close the screen, then the LineageOS logo animation will appear and the system restart.
