[ROM][11]LineageOS 18/18.1 Z4Tablet[SGP712/771]

[alex009988]

There is Android 11 ROM for Xperia Tablet Z4.
It's quite stable.
Kernel sources
What doesn't work:
- when the tablet is off, during charging, the diode will always light red;
- external SD Card as internal storage;
- restart into recovery;
- tablet encryption;
- SELinux proper configuration for a proper security.
How to install:
1) use TWRP 3.5.0.
2) do factory reset (wipe)
3) Flash the firmware, nik,bit or flamegapps , magisk 21 and that’s it.
Change log:
20201206- initial build.

Last builds (mirror) are here.

I found that I cant install vanced YouTube with lucky patcher or SAI, with vanced manager it's OK. But root version says google services is not supported on this device. I checked with both bit and nik gapps, but no luck. Anyway to use root version with los 18?

Update new rom dated on 11 Dec 2020 :
- camera now works
- fix some sepolicy denials.

I found that "reboot to recovery" doesn't work. Only Power + -val is only way to get the recovery.

Thanks for the R version for our device.

I found an issue on play store. I can't download some games (like Walking Dead Road to survival for example). When install begin it stop and an error appears.

Thanks for the report. Not sure why like that, perhaps due to LOS18 is still beta?

The same thing with war robots.

Battery consumption on karen-windy is huge as always on this. The android system itself lost 46% in 12 hours idle.

True. Battery drains to 0% when leaving the device switched off or on! Red LED stays on even when device switched off..

Any fix available or updated builds?

else need to revert back to stock...

Sabar made Los18.1 build which should reduce battery consumtion. But it also brings new bugs, no exfat for sdcard, half of screen is disabled after wakeup in many cases. I hope it'll be fixed soon.

 

[alex009988]

Half black screen bug is fixed with 20200103 rom. You may need also to reformat sdcard as external storage.

How's the battery consumption?

How's the battery consumption?

I remember los15 and 17 had serious problem with battery consumption so it was hard to use, now it's better. I use now aicp 16 but I was using stock marshmallow 32.2.A.5.11 several days ago. The stock is amazing, fast, no kernel panics, bugs at all. But I had a battery life there only for one day even with stock, as I have it with custom los14. So los14 maybe is more battery consuming a little bit. But don't except that android 11 is less buggy and battery consuming than los14.
As far as I tested android 11 it's more or less OK, even for now it can be used for daily usage. But it will likely to be a bit worse than los14 according to battery life. I think you can backup the stock with twrp 3.4.0 and try android 11. If it's not OK for you, you can easily restore the stock by twrp.

Do you use this marshmallow firmware with AICP 16 and LOS 18 ? If no, which one ?

And what about kernel panics, reboots and some games impossible to install on play store on your side on LOS 18 ?

I haven't used stock for years, but some days I've gone back to it just to see and find out what about root here. The last nougat there has no way to get the root, so I've downgraded to marchmallow. I also uploaded some stock ftp to my cloud.
Now I used aicp. Kernel panic are possible here but over two days I havent faced a one.
And yes, big games like war robots and call of duty are impossible to install with all nik, bit and flame gapps. There is some storage permission problem even though that I gave the neccesary ones. But you can find the games on 4pda.ru download and install them. The other bug is that vanced root YouTube doesn't work with all three gapps too. Maybe the reason of two problems there is still no opengapps for android 11.

 

[alex009988]

I found some info about YouTube bug https://github.com/YTVanced/Vanced/issues/201

 

[alex009988]

There is the error when downloading war robots.
01-07 18:15:19.260 E/Finsky:download_service(10456): java.io.IOException: Can't create file:///storage/emulated/0/Android/obb/com.android.vending/com.pixonic.wwr/temp.main.106419.com.pixonic.wwr.obb
So I decided to check storage/emulated/0. I tried ES file manager and root explorer. And find that emulated folder is empty. But it should be not. Maybe be its a clue.
