[ROM][UNOFFICIAL][13.0] LineageOS 20 for Galaxy Tab S6 Lite

[Linux4]

LineageOS is a free, community built, aftermarket firmware distribution of Android 13, 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:

• Follow the instructions here

Downloads:

• Builds: https://lineage.linux4.de
• GApps: MindTheGapps

Reporting Bugs

• DO NOT Report bugs if you're running a custom kernel or you installed Xposed
• DO NOT Report bugs if you're using TWRP
• DO NOT Report bugs while having Magisk installed (especially with Zygisk enabled)
• 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.

If we already have LOS 19.1 and recovery, do we still need to install the new recovery and factory reset?

edit: I renamed the new recovery image to recovery.img and then used 7zip to make recovery.tar and flashed it with Odin. But when I booted to recovery, all I got was a blank screen. Had to reflash the 19.1 recovery to get it back.

May I ask for screenshots? This is amazing work

May I ask for screenshots? This is amazing work

It appears the dev wants you to use Telegram for support and doesn't answer questions here in XDA. But I didn't get much support there either. When I asked what gapps to use, It just pointed to the Nikgapps site. But when I flashed the CORE version for T, Play Store didn't recognize the internet connection. Tried to revert to 19.1 and it wouldn't let me. Claimed it was a downgrade and not allowed. Had to flash the latest stock version via Odin, with all of the Samsung and Google bloat.

 

[lewmur]

Well, I got it to work in spite of the lack of support. Had to use the OMNI version of Nikgapps instead to CORE. One little nit pick discovered so far. /Setup/System/Status Bar setting to change the battery icon to text and show percent doesn't work. But that is easy to live with.

LOS 20 recovery here. I do think we have to use same recovery version as the instructions say.

The image has been updated today and now I see the lineage OS 20.0 recovery.

if flashed it with the old recovery but the zip check false and then you have to flash anyway
i check and the file size of both recovery where the same thought that is just for the ones that need it for flash for the first time

Just downloaden every thing with a AVG Antivirus alert.
For now I'll wait and maybe test later.

edit: the alert was from a know false positive.
For me better safe than sorry.

Well I built that zip myself, I can assure you there's no malware.
BTW Antivirus apps on android are only a waste of resources.

Updated with September securitypatch and more lineage features

 

[lewmur]

Is the changelog link broken? When I try it to see if I want to flash the latest version, it just times out.

You're not owed support by anyone. OP could flip off every user and **** off forever, but they'd still have done their work for the community. Thanks for the tips, though!

I didn't claim I was owed support. I merely stated that I didn't get any and that I was able to get it working in spite of that.

Device reboots after opening camera. Probably issues with camera hal

 

[chuffy123]

So far so good, except I cannot for the life of me get the Google keyboard to work...all other gapps are fine...

 

[lewmur]

Well, the dev for this ROM has convinced me to sell my S6 and buy a newer tablet that has support here in XDA. Apparently, he will only offer support in Telegram because, in that app, he can ban anyone who disagrees with him. So, no support if you want, TWRP, Magisk, Nixgapps, custom kernels or anything else he doesn't like.

What reason would we have to ban people who want support? He doesn't provide support for TWRP because it's a discontinued project and because it worked terribly on the tablet. That's like asking Samsung for help on a flip phone you bought in 1994 that's been discontinued for quite a while. I don't think I recall him actively rejecting people's technical support for Magisk, NikGapps, or Custom Kernels when I was in his Telegram, he only said that he recommends alternatives to Magisk and NikGapps. I don't know if you're writing this after you were banned but the only time he proactively rejected support in people's devices is when TWRP was in the equation.

{Mod edit: Quoted post has been deleted}

It is being actively supported by legacy devices that can't handle encryption and on ROMs made by unknowingly devs.
Also you were told multiple times that encryption is not an optional thing, especially on T. And some users do care about their data not being just accessible when the device gets stolen.
