Hi everyone,
i just flashed the latest 17.1 on my T819 (gts210velte). I still have the wifi issue a lot of people have reported. Wifi drops at random then reconnects. Is there a solution out there?

I have tried some apps, but they don't work. Some say the device can't handle 5Gh network. Maybe i should create a second Wifi Network with only 2.4Gh.

Would anyone have an idea/fix?


Edit:
One more question: will the Wifi ROM work on the lte model? I don't need LTE / Sim functionality. There seems to be more development on the gts210vewifi model, so it thought maybe i would use one of those ROMs.

No, don't ever flash a different model firmware. It's the only way you can hard brick and Android device with LineageOS.

And I fixed this by reflashing the newest stock firmware, via odin. Which was counterintuitive, because it was already on that before I switched to LineageOS. But it worked, I reflashed LineageOS after, and WiFi works great on my sm-t713 now

Thank you for this great Dec_update! A clean install makes my S2 T813 fly. Wifi, gps and fingerprint works fine. Sometimes I have a reboot but then I clean the cashes ..And everything is ok.

After clean flashing latest update (lineage-17.1-20221203-UNOFFICIAL-gts210vewifi.zip) on a new to me T813, no issues except this: Roblox loads a white screen. I realize this is super app specific and I should contact Roblox devs (already did), but can anyone think of why Roblox loads the loading screen, then just goes white? I have reinstalled/cleared data/cache/clean reflashed rom, and it's always the same. How do I even go about troubleshooting this app on this rom? TIA, my kid will not accept the tablet without Roblox lol (Google Family Link is enabled but set to T for Teen with no time limits on Roblox).

After applying the latest update, my WiFi dropouts have gone from a few a day (which I've always had on this ROM) to pretty much every hour.

I see there is a previous suggestion to reflash the stock firmware to fix this. Probably my ignorance here but, I can't see what this will achieve if I'm just going to restore this ROM again afterwards, so I just wanted to check if this was a known problem with any other solutions I could try first.

Thanks.

No issues with WiFi here on this ROM. However I am facing issues with YouTube. When I minimize to pop-out view and resume to normal view the screen goes black. The audio plays fine and video only shows for a micro second if I pause the video. Any thoughts on what could be wrong?

Just got this device and it's been a LONG time since I've messed with any custom roms and flashing. How's the stability on T813? Are there any min/max requirements for Odin and/or TWRP?

Very good, despite GPS being broken, the battery life is of several days.

There were/are some TWRPs that allow encryption for this tab, but personally I use it with standard TWRP and I go unencrypted.

Coupled with microG is still a valid device that receive security updates.

Hopefully we will have new interest in development of this tablet.

Like I said, it's been a long time since I've messed with custom roms. I have TWRP 3.7 installed and I'm able to boot to it. But now I can't mount any of the partitions when I go to wipe. I'm guessing it has something to do with the filesystem but I'm not sure what to change it to. I'm also trying to flash without an SD card, will changing the filesystem wipe my internal storage?

Edit - I was able to figure this one out. However, after installing the ROM and Gapps, it just seems to sit on the LOS loading screen. I've tried wiping and installing again with the same result.

Normal for this rom the first time, you have to force shutdown the device and reboot then will work.

Hi all, trying to add Bromite webview to this rom - methods I find all require "treble"-enabled devices which this tab doesn't seem to be? Anyone a working link that explains it for LOS17? TWRP, Magisk, root, adb, all available - only not the straight-fwd guide I'd need...!?

I upgraded to 17.1 from 5.December, and now my camera is not working anymore.

I have a SMT-813.

Before i was on Version 17.1 from 9.June - the camera worked like a charm.

Yesterday i updated to newest release from 22. December - changed nothing.

Have you got an idea how to fix this?

    Hey, No camera currently Not fixed in The Release of 3. March 2023.

    It worked until a few months ago and was then patched broken. I wish I hadn't made an update 🙈

    Looks like Google dropped support for AOSP 10. The LineageOS team will backport some fixes to LineageOS 17.1, but the Android security update version will remain on February 5 2023.

    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.
