Battery life is pretty good on the last build, nearly 9 hours sot of which 5h25m a rather battery unfriendly game (foe), before the 15% battery warning kicked in.
On 16.0 I always had that message after 6 to 7 hours max.

I just installed this ROM and I have a couple of problems. Antutu benchmark freezes at the 16% mark and screen goes black. I have to close the app to get the screen back. The other problem is that I can't get a TWRP backup. I get a createTorFork() error 255 while backing up the data partition. And I did format the partition to get rid of the encryption. The error occurs about the time the data partitionis almost finished backing up.

I haven't tried Antutu but I get the same problem with TWRP backup.

Are you using a work profile?

Are you using any apps that let you run multiple /dual copies of apps (like shelter)? I believe that can result in the TWRP error that you mentioned.
I'm not running anything like that. And TWRP has been backing up the apps I use on my other tablets. SM-T580 and T510 both running Lineage 17 ROMs.

Not gonna lie, I kinda don't really care about antutu. This is not something worth spending time on, it's not like you're going to be playing with antutu every day lol.

Well I requested TWRP rebuild, no idea how long that's going to take but if you really need TWRP backup right now, you can flash this build https://f.kremowka.xyz/get/6dddfb78-4c47-47ac-9a35-7a283d66f7b3 (rename to recovery.img)

I've been using LineageOS a couple of years on Motorola phones, and would like to use it on this tablet, too.
Before flashing, I have a question:
Is it possible to take a backup/system image of the stock android, which can be re-flashed in case I want to go back to stock? E.g., if I want to sell it, or if LuK1337 stops developing on that device (and I fail with compiling on my own)?

There's no point in doing that. Samsung images are always available to download on sammobile/updato/samfirm.exe and flashing stock FW that way is more reliable than twrp backup anyway.

Thanks for the fast reply (however, doesn't exactly answer my question). But I didn't know about sammobile either (am new to samsung devices at all). Will have a look there, too.
Keep up the great work, Luk1337.

I followed every step of the install instructions from stock but ran into problems. Maybe someone here explain how I can fix it?

After installing the TWRP recovery via Odin and booting into it, I get the oldschool non-graphical TWRP menu which has way less options. The file I installed was twrp-3.3.1-4-gts4lvwifi.img.tar. How can I get the new TWRP menu?

Well, I did.

1. Unlock the bootloader
- Connect to WiFi network
- Enable OEM Unlock in developer options
- Turn off the tablet
- Boot to download mode manually by plugging in USB and holding all the buttons for few seconds
- Follow instructions on the screen
Done all of this, it is definitely unlocked.

2. Connect to WiFi network and make sure OEM Unlock in developer options is still checked
It was still unlocked and the option is even greyed out.

3. Flash custom VBMeta image ( https://dl.twrp.me/gts4lvwifi/vbmeta.tar.html ) in Odin ( use AP slot )
I did that.

4. After flashing VBMeta, boot to stock. It'll likely ask you to wipe data, if so do that
The old-shool text TWRP told me to wipe and I selected "Yes" and did so.

5. Connect to WiFi network and make sure OEM Unlock in developer options is still checked
It was still unlocked and the option is even greyed out.

6. Now you can flash TWRP ( https://dl.twrp.me/gts4lvwifi ) in Odin ( use AP slot once again ), for convenience you can hold volume up while flashing it so that you boot to recovery right after it's flashed
I did that, too. The only difference is that I get a Samsung splash screen that tells me that the device is unlocked and unsecure. In this screen I need to let go of holding volume up, press power and then continue holding up. This brings me into the oldschool text interface of TWRP.

Umm which twrp file did you put in Odin?

    Well… It was working. After a few reboots and installing among other things Magisk, afwall and EdXposed, I'm again with no sound and no screen rotation… full logcat from boot until unlock here https://paste.ubuntu.com/p/Cmmbf7kxqp/
    looks like /system/bin/audioserver crashes this may explains the sound problem but not the rotation one.

    Any one knows how to solve those issues?
    Uninstall EdXposed has to be the very first thing any sane person would do. It is known to be the source of endless headaches and badness.

    LineageOS does not just do random things and stop working without any reason. You need to reverse whatever you did that made things not work, and then figure out how to live without them.

    I would estimate that around 75% of all complaints about "this ROM has stopped working" are self-inflicted wounds. And it is quite frankly just pollution in the forums.

    On my end flashing CTK1 did end up with :
    - no sound (volume rocker was fine though)
    - no rotation
    - no video decoding
    - long boot time
    was still on 17.1.
    Flashed 18.1, behavior did not change.
    Flashed CTI1, problems aforementioned disappeared. (while keeping 18.1, no userdata format)
    Was previously on what seems to be a mix of ATE3 and BTG3.
    Now I guess I'm ATE3/CTI1.
    Might be because of me flashing manually with TWRP (BTG3 and later) so not everything may be writable.
    You can't flash firmware with twrp.

    LineageOS is a free, community built, aftermarket firmware distribution of Android 10, 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 gapps
    • Reboot to recovery
    • Flash the latest build and gapps
    • 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)
    • If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log
    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.

    8. Format data
    9. Reboot ( make sure to not install TWRP app when TWRP asks you to )

    Also Odin download for those who can't find it on their own https://build.nethunter.com/samsung-tools/Odin_3.13.1.zip
    ( sha1sum 1057496afa34bfdf7e77caf0b99207dca77fcb2d )

    Builds 20200824+ depend on Android 10 firmware, and thus from now on the recovery will abort the installation if you're still on Android 9 one.

    You can update the firmware by flashing following Odin package: https://github.com/luk1337/gts4lv-fw/releases/tag/T720XXS2CUA3.

    After the firmware update you should be able to flash newer builds.

    Hi, 20190928+ OpenGapps builds should work just fine without doing anything special. B-but there's a catch, you'll need to update to TWRP 3.3.1-4 or newer ^.^
    Have fun~!

    Also OpenGapps apparently moved their builds there ~ https://sourceforge.net/projects/opengapps/files/arm64/beta

    Do you think there is chance lineage based on android 11 will support this tab?
