You didn't really read what I suggested to do in #315?
Actually, I did, and in fact I read those instructions before I made my first post. Unfortunately, those instructions assume that I already know how to unlock the bootloader and use Odin, hense my initial post asking whether there are more detailed instructions somewhere.

Well, I eventually got it installed, but then it got stuck during initial setup, but wasn't able to get through the initial setup.

When I booted up after installing both LineageOS and OpenGApps, I got the following

Getting your tablet ready...
Chose my network
Copy apps and data: Chose "Don't copy"
Just a sec...
Checking info...
Then I got a black screen.
After a while, I was able to get it back by pressing the power button, but then it just went back to "Checking Info", and then the black screen again.

Tried this with both "Stock" OpenGApps version and "Nano" version.

After struggling with this for a while, I gave up and re-installed the stock firmware (which was a bit of a challenge in itself).

I think the mistake you have made was that you flashed the ROM and opengapps together. The way to go is to flash the ROM. Then boot the tablet. Then reboot to recovery and flash ngapps for Android and 11.Then reboot the tablet again and follow the instructions. If you want root then you reboot it in recovery again and flash it to magisk 23.

You're right - I did flash LineageOS and then OpenGApps without rebooting in between.

Thanks very much for the suggestion. It may very well be that that will fix the issue, but I stressed myself out yesterday too much when I felt on the verge of bricking my tablet, and I don't think I am ready to do that to myself again just yet. Maybe I'll try it again at some point, but not right now. :)

I asked and the havocos forum regarding viper4android. Has anybody successfully installed it with this ROM? I have installed it in my t825 but it doesn't seem to change the speakers sound at all. I tried changing all the parameters with no success.

Do I need an SD card to install or will it work with internal memory? My SD card slot doesnt work…

You can install a custom ROM using ADB sideload in TWRP. SD card is not necessary.

Turn on the ADB sideload mode in TWRP then enter `adb sideload rom_name.zip` command to flash.

On my T825 Privacy browser and Vivaldi are the only ones I use and I have no probs with them.
yeah but brave, chrome, kiwi, opera, lite browser, etc are crashing, have jittered scrolling which affects the whole system after a period of time, only other browser i used is firofox/fennec, just need to know if im the only one and/or if there is a fix for it.

First of all I would like to thank Awesometic for the excellent ROM. I have been using this ROM from the first day it was uploaded without any crashes. Everything works perfectly and I managed to pass safetynet test so my t825 is certified under magisk 23.
As a long term review now, I have to issues to report:
1) Every time I use OTG (with a flash drive) my WIFI does NOT function correctly, or does not function at all.
2) Quad speakers function all the time but it is my impression that the power coming out of them is less than 50% the original power, i.e. the power when the original ROM was installed.
Has anybody noticed similar issues, and if yes, does anybody know how to fixe them??

Fantastic rom , I too am having the volume issue how do we go about boosting it , is there some way a non dev like my self could assist?
Thank you for the fantastic rom
 
....
1) Every time I use OTG (with a flash drive) my WIFI does NOT function correctly, or does not function at all.

Was just about to test it but the stick wasn't correctly recognised.
Although just tested as usable in another device.
When trying to copy something onto it from the NAS using Total-Commander it just showed what's in the pic.
Properties rwx were the same as SD (770).
Format vFat might be the cause I thought so sitched to TWRP and formated as ext4.
Reboot - > system says problem with the stick (do I want to format?) so I did - > vFat.
Gave up but no WI-FI probs meanwhile.

Just another info: battery usage in deep-sleep (fmight-mode) turned on is brilliant ~0.1%/h.

I found the following in the internet to overcome the OTG problem and be able to use a stick right away. NOTE THOUGH that after this I had the problems with the WIFI that I mentioned in my previous message, only when having the stick plugged though, but I got used to it.... either WIFI or OTG....
So the procedure is the following:
use a terminal emulator and type su to become superuser ( you must be rooted to do this and I am via magisk).
While you are superuser type the command: sm set-force-adoptable true
Then press enter
That's it

    Hello all,

    I updated LineageOS and HavocOS and uploaded them to the forum.
    In this update, besides the latest Android sources, I added some more fixes including the fingerprint recognition issue.

    Please check the update changelogs, thanks. :)

    @Awesometic thx for the info and your time for our device but even with the existing bugs I'll keep my T825 on your LOS19.1.

    I do have a plan to fix the major bugs on my LOS 19.1, I hope I can fix them soon. 😅

    Thanks for the update! My wifi tab s3 was having black screens after trying to unlock the screen from sleep on the previous version. Seems to be fixed now.

    Thanks you so much.
    I made an update via TWRP, straight flashed without any wipe.
    Everything is working fine, before the update I had sometimes that black screen after fingerprint reading, now after a few days that failure is away.

    I've been running this ROM on my Tab S3 for well over 6 months (and of course updating as soon as a new version is released) and I have to say I'm quite impressed! I do have some bugs every once and a while but nothing a simple reboot doesn't fix! I greatly appreciate the work you've put into this! :)

    # LineageOS

    LineageOS is a free, community built, aftermarket firmware distribution of Android 11, which is designed to increase performance and reliability over stock Android for your device.

    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

    Hi all,

    Finally, I can take a picture with my Tab S3 :)

    But still, there are some annoying bugs about the picture resolution, a flashlight behavior, ... but yeah it is usable when I take something using slightly lower resolution without the flashlight.

    Also, for now, both the LOS camera app and Snap camera are not working well while Open Camera and Google Camera seem to be working well.

    For now, the major problem is that if I use a flashlight in the camera app at least once, the overall GUI animations slow down even I closed the camera app.

    So, when I publish the camera fixed version, at least I will fix this most bothering thing even though I can't fix it all for the camera.

    Hello all.

    I uploaded the new version, including fixing the power-off mode charging.
    I'm using the LPM binary that is from Samsung for the power-off mode charging. When you plug in the charging cable while the tablet turns off, you can see the original charging screen you might see in the stock firmware. :)

    And I tried to fix the Bluetooth inputs and the OTG drives issues but I couldn't. I can reproduce these problems but I cannot find how to fix them for now. But I can confirm that the wired input devices are working such as a keyboard and a Playstation 4 controller.

    Please check out the first post of this thread. :)

    Great news here. The next release will include the fully-working quad-speakers. :D
    And I also have implemented the audio rotation codes for the screen rotation.

    Actually, I already have used it for about 3 days, and I think it looks working flawlessly.
    And, for the alternatives of the Dolby Atmos, I have tested with the Dolby Digital Plus module with Magisk and I can say that it is awesome. :cool:

    The new release will be uploaded before this weekend. :)
