[ROM][UNOFFICIAL][11][EAS][SM-T820][SM-T825][2022-05-08] LineageOS 18.1 for Galaxy Tab S3

Search This thread
I'm still getting the Google drive file from 11-30, not 12-3 when I click the OP link -- or does 11-30 include the new kernel you referred to in the 12.3.2021 update?

Is everyone using the 20211130 ROM who's posting about it?
Yeah, 20211130 is the latest version now. I'm sorry for the ambiguous titles.
Will change them to the same date. 😀

First of all I would like to thank Awesometic for the excellent job. I have installed the previous to the last rom and my t825 works continuously for 1 month without any problems at all. Two things I had to change were to follow a procedure I found on the internet for otg to work properly ,and a procedure I found (using magisk) to make the t825 pass safetynet tests. Now my tablet is certified and fully functional.

I need though your help PLEASE. I want to update the tablet with the latest ROM. The one with the new kernel. I saw that I have to wipe system and cashes. Do I have to reinstall and gapps because of this? Is the tablet going to be certified after the installation? Or I have to repeat the procedure to recertify t825?
Thanks in advance...

Thanks in advance...
At least I did flash them together with the ROM.
You could try without of course.
I don't care about "safety net" so idk.

@Awesometic : I still have the same issues with the secondary/non admin user as described in my post https://forum.xda-developers.com/t/...-18-1-for-galaxy-tab-s3.4293069/post-85588047

Will you be able to fix this issue somehow. It looks like a permission issue for non primary users as the system shows that there is unsufficient space. As a hint which may help to localize the issue. When trying to start amaze file manager as a secondary user it will instantly crash with a file I/O exception. Please have a look. I can provide additional information if needed.

BTW, with the last version the WIFI MAC was changed. Not sure if this is on purpose or not.

Ah okay, will reproduce that issue on my device too.
But for now I'm focusing on the kernel upgrades for battery improvement and better UI experience. Through that work, I might fix the Android OS side issues too. So please test again later with the upcoming kernel versions. :)

Sorry but I could not find how to update in the post you sent neither in the posts close to it.

Is there some set of instructions? I really want to update mine.

Dirty flashing will work. This means, just flash the new version using TWRP, and wipe caches.
But moving to F2FS requires you to format the current data partition. So please be aware of that before continuing. Currently, F2FS is an option that has better I/O performance but a little bit unstable than EXT4, very relatively.

Quoted here what "dirty flashing" means from a Reddit post.
A "dirty flash" refers to the process of flashing a new version of your ROM over the top of the one you have, without using the "Wipe Data/Factory Reset" option in recovery. Even if you intend to dirty flash the update, you should always wipe cache and dalvik cache.

  1. Wipe Data/Factory Reset: This option erases all data on the device. Every application, and all data generated by those applications, will be erased. If you do not wipe data, all the data files generated by every app on the system will persist through an upgrade. This includes the data files generated by core system apps, like the phone dialer, the Android UI, its option menus and core features. Remember, everything you do on Android is an application that generates data! NOTE:The storage you see when you connect to USB will not be erased.
  2. Wipe Cache: Every application on the system, even those that run things like your UI and the options menus, generates cache files. These cache files are more or less unique to the current installation of Android you are using, and are generated dynamically. These cache files help Android load and run faster. When changing ROMs or updating to a new version of a ROM, you should always wipe the cache partition, or you're gonna have a bad time: Force closes, boot loops and sluggish performance are just some of the perils that await you.
  3. Wipe Dalvik Cache: Android executes programs inside of software system called the "Dalvik Virtual Machine." The DVM interprets and runs APK files for Android. Dalvik maintains its own cache to again improve performance for your device by offering faster app loading and execution. The Dalvik Cache is again unique to the current installation you are running, and it should always be wiped whether you're installing a new ROM or simply updating versions.

Performed dirty flash but kept EXT4. Everything works fine till now.
Thank you very much for the perfect ROM and your help

Great job. All 4 working speakers have brought life to this tablet.
Found something else that doesn't work:
The cover is a book. The screen does not go out and does not light up when opening and closing the lid.

Yeah, while I was upgrading the kernel to merge the upstream patches seems like I broke that feature. I'm using a flip cover case too, so that is quite an annoying bug :confused:

I found which function handles that flip cover flips, and checked that function does listen to the status (opened and covered), but the screen is not actually responded by that function. I'd like to fix this issue too.

Hi, this sounds like a great ROM!

I've got one question regarding Wifi Display/Miracast. The changelog mentions Wifi Display was removed in v. 2021.8.13. Is this a temporary state of affairs or is it a general restriction (maybe due to Google pulling support for Miracast in stock Android)?
I'm asking because I rely on Miracast when using my tablet for teaching, so if this feature is permanently disabled, unfortunately I won't be able to use this ROM. But if there's a chance the feature comes back at some point, I'd love to try it out!

It's so annoying that Google decided to abandon Miracast claiming that "it's not widely used" and that one should use their stupid Chromecast instead, when the Chromecast clearly doesn't allow you to do what Miracast can do, namely connect to any Miracast enabled device (or use the Wireless Display dongle) and directly cast to it without the need for internet access. Sorry for ranting, but I just want preempt suggestions of Chromecast as an alternative - I got one of those and it doesn't work without connecting it to some sort of network first, which makes it largely useless in most mobile teaching environments. Using a phone as a hotspot is, to my mind, no alternative - why should I burn through battery (and data?) on an extra device when there should be no need for internet access in order to project local data to a local device in the first place? (Imagine an HDMI cable that only works as long as it can access the google servers :p )

    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. 😅
    1
    ....... , when I tried to turn it on for the second time, it got stuck in a bootloop.
    P.S.: I can't access recovery
    Download mode still accessible?
    If yes it might be worth trying to just flash TWRP via Odin and, when rebooted to recovery, to make a clean flash (incl format data) from SD but this time with LOS19.1 which imo is much better anyway as being more stable.

    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.

    # 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. :)
