sabar_op do you have a tablet? Or do you make assemblies without it?

Syslog or logcat please. We need to be ready that this bug maybe be never fixed. Sabar doesn't have sdcard and without sdcard big games should install well. Being the developer is a hard and often ungratefull work that takes huge period of time.
Bluetooth may not work because of SELinux enforced.
I also wanna say without the sabar we would have los14 and no more. And even what I built, some nougat roms, I did that with his huge help. So we must really grateful to him.

My log is at https://gist.github.com/mcfisch/4d4ceaf37f3cdfcf5d3127f6bc234189.

I also can't get the encryption going. Other than on another device (Moto G5+) where I'm not getting any forward I here I'm at least still able to boot. The respective error that was logged (overlapping partitions due to not enough space or so) I was able to fix be shrinking /data, but it still doesn't encrypt. It just reboots and that's it.

You are using SGP712 (karin windy) and not tested by myself ( I am using SGP771).
In your log looks Bluetooth HAL is crashed...if in the prev version bluetooth is working it because SELinux is disabled. It means there's sepolicy denials during boot up. Try grab log once your device is boot as fast as you can or use your pc to adb logcat since power on to catch sepolicy denials.

Check prev post, encryption is still not working in this device.

Thanks for the new build As mentioned before there is a Problem with deepsleep on my karinwindy since build Form may 6th. Device doesn't wakeup from deepsleep. Only way to "wakeup" the device is to push the Volume button + Power button.
Unfortunately same problem occures with the last build Form may 16th.
Ging back to last build from March.

Similar answer with prev post for karin windy...it may because SELinux...quickly grab a log once device boot up and send me through pm..

Will this work without root? I've had issues rooting my Z4 tablet (wifi), before.

About big games downloading https://xdaforums.com/t/rom-11-0-un...-1-sumire-stable.4174189/page-7#post-85090751
So seems all kitakami devices have this problem.

Thank you very much for the hard work.
Just wanted to share a small thing regarding battery consumption in stand by mode (wifi, lte off and battery save mode on. And no use).
The version 20210302 is using 0,1% pr. Hour
And the 20210516 are using 0,2% pr. Hour.
Just wanted to share my experince with you guy´s
Thanks again for keeping our z4 karin alive.

Try latest boot.img in my link. Flash it using twrp.

 

[torben5247]

That fixed the battery drain issue

Try latest boot.img in my link. Flash it using twrp.

The boot.img fixed the battery drain issue, thanks

 

[torben5247]

Hate to repport this, but there are an issue regarding deep sleep in the newest version even if a flashed the boot.img it uses 0,9% pr. hour when laying and no use, only wifi switched on. that is almost double consumption compaired with the version 20210302. But if wifi is switched of it is less than 0,1% pr. hour if it isnt used for 2 day´s or more.
Thanks for keeping our tablet karin allive, and thanks for the hard work ;-)

Yes...that's is a known issue in los18.1 and it's related to latest wifi HAL from lineageos which not supported by our legacy device kernel.

There may be some update to solve this issue...and I will update it in next build.
