Hello. I'm not experienced in Linux or Android, so apologizes for my probably "simple" question. But since I don't want to waste my perfectly fine Tab S2 tablets I need to ask.
If I flash this ROM of 01.01.2022 to my gts210velte, do I get rid of the notifications telling "This build was signed with public keys" and "SELinux is not enforced, your security has weakened"? I get those notifications with the original ROM of this thread which I installed like a month ago. I tried to search answers about the actual meaning of those, but no straight answer for a simple guy. It really makes me worried about safety of my personal data.

I will try to release updates on a monthly cycle when security updates are aviable.
Tested around with auto update functionality yesterday and it seemed to work.
Plans are to include that in the next release.

Iam by no means a developer, at least regarding Android, so the codebase is what it is.
Dont expect bugs to be fixed as I don't know if there is active development going on from team-infusion-developers side...

I want to echo thanks for your efforts in updating the SM-T719 / gts28velte with LineageOS 17.1. I can't seem to find a definitive answer in this thread, though, about whether LTE works on any of the Android 10+ ROMs like this one. At times there are suggestions that there were no radios for the Samsung Tab S2 available to port for 10/Q and later but I can't find confirmation and I'm loathe to wipe a perfectly good load of 16.1 just to see if LTE works as it does in Android P/9. Does your updated Lineage 17.1 ROM come with a working LTE radio? Thanks for your support. I'm all in for coffee if it is...

No, because the Galaxy Tab S2 is in terms of official LineageOS support deprecated. These builds here are unofficialy built and therefore cant be signed with the official LOS keys.
Second SELinux was disabled to enable development, and/or porting to LOS17.1.

As said before, Iam building on exisiting sources. The very first post states under bugs the Radio Interface Layer does not work for LTE enabled devices.
Most likely due to protected bootloader..
If it works on 16 I would not change it.

Wickenberg seems to be up and running again.
Just checked: there are new builds for all devices aviable - 16.0 and 17.1! :D

Flashed the 01-18-2022 image for sm-t813.
today the auto updater showed an available update -> 01-20-2022.
Download worked. Install failed because of a verification failure.

Any hints? Is the auto update routine ready to go?
So adb sideload or TWRP it is?
Thx!

Load the images from the homepage and flash them via TWRP. It works. For me, the image of 20.01.2022 runs perfectly.

If there are difficulties with the download, you can switch to "Desktop Version" in the browser. Then there is no error message and the download works. Or you can take the app.

I intend to do just that. Thank you to the developer. I tried building it myself a couple times because I really wasn't ready to let it go, but I had no idea what I was doing. Waiting a couple hours just to have it fail at the end, not fun.

Hi all,
if I understood right, even after the latest update GPS is still not working?
Click to expand...
Click to collapse
...unfortunately that is correct. The problem exists,beginning with all new builds around April last year.
Until now, no one was able to fix the issue, as there is no active development in this branch of the device tree. The main developer is still active, but engaged in another project.
I myself am able to compile my own builds as for example BKayNrOne does, but I am also no developer, so I am dependent on the sources as they are.
It is a pity, but it is like it is.

Camera App is not. 21.01.2022. SM-T813

...that position is for sure not GPS-related. Google is able to derive its postion from multiple sensors (Wifi, GSM...)
You have to check via a GPS-App like GPStest, if there are GPS-satellites in view. That is currently not the case, but I have to say on my device. But I doubt it. Sorry, but for me the problem still exists...
By the way, there are a few camera apps, that work...

    LineageOS is a free, community built, aftermarket firmware distribution of Android, which is designed to increase performance and reliability over stock Android for your device. All the source code for LineageOS is available in the LineageOS Github repo. If you would like to contribute to LineageOS, please visit our Gerrit Code Review.

    Code: 
    * [B][U]Your warranty is now void.[/U][/B]
I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or your getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at us for messing up your device, I will laugh at you.


    FREQUENTLY ASKED QUESTIONS

    (Please read them BEFORE posting anything in the thread!)​
    Q: The room is bootlooping the first time I attempt to boot into it after clean flashing. What should I do?[/COLOR]
    A: Force reboot using the Power and Volume Down buttons. The rom will boot properly the second time around. This is a known bug and it affects clean flashes only.

    Q: Whenever I try flashing any lineage-17.1 build, I get the following error in TWRP: Updater process ended with ERROR: 7
    A: This error appears whenever you try to flash an Q-based rom within a version of TWRP older than 3.4. Simply flash the linked below version 3.4 or higher, reboot back into recovery, and flash the rom zip again.

    Q: Will any of the variants ever receive official builds from LineageOS?
    A: No.

    Q: How often will new builds be released?
    A: At least once per month: as soon as possible after each new Android security patch level is merged and whenever a new feature is added or a bug is fixed.

    Typically if you do not do a Clean Install then you are not allowed to report errors or problems. If you Dirty Install and you do have problems then you will be asked to Wipe All and Clean Install and see if the problems still exist. This is a DAILY changing rom and any bug that you found was not working on the previous day's build may be fixed with todays daily build. On a side note, the code implemented to fix that bug could potentially break something that worked on that previous build. So reporting problems on a day old build that you dirty flashed over whichever build of whichever rom you had flashed previously will not be accepted as a true error.


    Problems known to happen after a Dirty Installation​
    1. A muddled up mess of a system. You are taking a rom and installing a newer rom with changes over the top of your old rom. Between these two periods of time during which you used your tablet and created data, changed system options, and used apps. This is absolutely increasing the risk of causing problems somewhere in the system/data partitions. Some people have luck with Dirty Flashing. However, it's always hit-and-miss because of what we mentioned above about bug fixes breaking previously working functions. Dirty flashing doesn't only create problems if the source code of the system data and the system settings of the new build are significantly different from those of your previous build. That's not to say that Clean Installing won't ever create problems, but only bugs present on a Cleanly Installed rom are relevant for development purposes.

    * Clean Install: Fully wiping everything and installing the rom onto a fully clean system/data partition of the tablet.

    * Dirty Install: Installing the rom and GApps over top of the older rom to save time and not have to reinstall all the user apps and tweaking system and app settings that usually take a lot of time to set up as you like.

    Bugs
    - The rom bootloops only after clean flashing. Force rebooting allows it to boot properly the second time and every time afterwards. See the FAQ's above.
    - The cameras work, but with a delayed response, so they are impractical to use.
    - T719 & T819: RIL does not work at all.
    - You tell us!

    Changelog
    All major features and bug fixes are discussed in detail by the developer in the thread, whenever they are implemented. All builds include the latest upstream Changes for all devices from LineageOS.

    TWRP 3.5.2_9-2

    The official TWRP for all four variants is built by TeamWin's servers from the outdated android-6.0 branch. A major bug in this branch is that mtp is broken, so I ran my own builds from the android-7.1 branch. I fixed hw encryption, which is why I bumped the version number up to "-2":

    Since all ROMs got deleted and it looks like there won't be any new ones I decided to do something about this.
    My T719 is still in perfectly good shape and it would be a shame to dump it to the landfill.
    So I spend the last two days digging through Repositories and recreated the build processes originating from ripee's original post, giving these devices a second life.
