No worries. It won't be the last issue we have. You should start to share logs though.

You're right :)
For which issues do you need logs ?
I do have 4 of them on my list: gps, cam, bluetooth and fm radio.

Hopefully I'm able to provide you with necessary input ..

gps is a bit tricky but I can gather the logs myself.
camera I won't bother looking into it until we have no more issues, so no need for logs.
bluetooth.. would be nice if you can start taking a logcat with the bluetooth off, then you turn it on, connect the headset, and play some music or video. That should help.
fm-radio I already have half idea of what is going wrong but if you share a logcat about it won't hurt.

Logcat regarding fm radio see attachment.
This evening I'll submit a logcat regarding the bluetooth issue
@juanysara: Thanks, that's exactly the app I used ..

    If you know how to use it, it won't damage. If you don't know, it can make it difficult or even impossible to repair by software ... Only suitable for the SM-T280

    Gapps not installed / are not visible in app list

    hi,
    i installed your latest lineage-14.1-20200908-UNOFFICIAL-gtexswifi.zip together with the pico gapps.
    according to trwp-3.4.0-3 everything worked fine...

    it also boots and starts without problems...

    but: the gapps (espacially no play store) are not there ... only the 15 "standard" applications ....
    even when i started from scratch again: full wipe, install 20200908, nano gapps this time => same result...

    i also tried to download / install the play store .apk but it does not work (froze on the first page)...

    do you have any hint what i could try ?

    thanks a lot, christoph

    I don't know why this is happening.. but a simple workaround is to mount system first, then install gapps.
    In TWRP: Mount -> System -> Go back to the first page and install gapps as normal.

    Hey there, Thanks for this awesome ROM. I can't seems to boot up this latest ROM. Just stuck on Samsung Logo. I am using the Latest TWRP 3.4.0.3, I tried dirty flashing the ROM, and also Clean Flash by Wiping Dalvik/ART Cache, System, Data, Internal Storage, Cache. And then Formatted Data as well. No joy at all. Anyone got any idea how to go about booting in , I would be really appreciated. Right now, I'm just going to use your previous build i.e Lineage 14.1 20200903

    Thanks in Advance
    Regards
    Lee

      LineageOS is a free, community built, aftermarket firmware distribution of Android 7, 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.

      Instructions :
      • Download the latest build and (optional) GApps
      • Boot to recovery
      • Flash the latest build
      • If you want GApps you have to mount system first:
        Mount -> System -> Go back to the first page and install GApps as normal
      • Reboot
      Downloads :
      Reporting Bugs
      • DO NOT Report bugs if you're running a custom kernel or you installed Xposed
      • Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
      • If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
      Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.

      Code:
      What is your--
      LineageOS version:
      LineageOS Download url:
      Gapps version:
      
      Did you--
      wipe:
      restore with titanium backup:
      reboot after having the issue:
      
      Are you using--
      a task killer:
      a non-stock kernel:
      other modifications:
      
      Provide any additional information (observations/frequency of problem/last version it worked on/etc) as needed:

      Known Bugs :
      • Camera doesn't work (use opencamera instead)

      For anyone trying to figure out how to get this or other ROMs working on the T280 with a valid google account (without FRP ruining all of your fun), here is what you need to know:

      * Follow instructions to install custom bootloader, ROM and GApps Pico (see OP)
      * Download ADB here: https://dl.google.com/android/repository/platform-tools-latest-windows.zip
      * Unzip to a folder, open a cmd prompt and navigate to that folder
      * On the tablet, perform initial setup and go into settings, Developer Options and enable root access (ADB only)
      * Connect your tablet to your PC.
      * Run the following commands:
      * adb devices (confirm that adb "sees" your device as connected)
      * adb root
      * adb remount
      * adb pull /system/build.prop
      * Now you will have a copy of build.prop in your adb folder. Edit the file with notepad, or some other simple text editor that will not insert hidden characters.
      * Find the following entry: ro.frp.pst=
      * Comment it out (disable it) by adding a # at the beginning of the line. Ex: # ro.frp.pst=
      * save the file
      * Go back to adb and run the following commands
      * adb remount -o rw /system
      * adb push build.prop /system/build.prop
      * adb shell chmod 644 /system/build.prop
      * adb remount -o ro /system
      * adb reboot
      * Add your google account. You could add your account before modifying build.prop, but if you forget and reboot you'll be out of luck and will have to start from scratch flashing the factory ROM, etc.
      * That should do it! You should now be able to reboot as much as you like.
      * If you want extra assurance in the event that build.prop ever gets overwritten, you can blank out the FRP partition with FRP destroyer (I recommend): https://forum.xda-developers.com/t/frp-destroyer-flashable-zip.3920067/

      When I tried FRP destroyer without modifying build.prop, I never got to install it with TWRP as FRP would already be blocking me from booting. It is possible that I was doing things in the wrong order, but I thought I would share just in case someone finds themselves stuck like I was. I am not a pro at this, I have used CM on a few devices in the past but have never dealt with FRP before. I prefer to share my learnings to hopefully help others in the future.

      Cheers!

      GPS should work now.
      Let me know.

      I'm having difficulties uploading new builds.. if anyone is building for themselves and want to share builds with the community, feel free to do it here.
