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

I publish here the LineageOS Builds 14.1 & 15.1. I create them with the Docker Image from MicroG, but without any MicroG components. Therefore GApps can be installed without any problems.
I'm only testing the 14.1 builds, as I'm currently using them.

I assume wipe is required if going from official build to this build?

If you go from 15.1=> 15.1 or from 14.1=>14.1 it should not be necessary.

What are the benefits you find in 14.1 as opposed to 15.1 on the shield tablet?

In 15.1 HWC is corrupt, so some apps are crashing( like netflix) Steel01 is hopping that he can fix it in Android Q.
In 14.1 all is great.

Ok, I just tried installing your build over the official build 15.1=> 15.1.
It just bootloops, Nvidia logo -> LOS load screen -> Nvidia logo -> TWRP -> Reboot from TWRP -> Nvidia logo -> LOS load screen -> Nvidia logo -> TWRP -... loop

Me too... Will try a fresh flash later...

I'd suggest wiping system but keeping data partition and then install the los 15.1 of your choice...

 

[The-Saint2k]

I have a feeling there might be a problem with my builds.

Has anyone done a dirty flash with gapps without any problems? (I only did this without gapps times and otherwise I always had to do a full wipe due to various tests anyway)

If there should be problems I would take the builds offline and test it completely by myself.

 

[TheToxicant]

I did a clean flash for 14 with the exception of wiping internal storage and had a flawless installation.

I wouldn't take them offline for that really...
Like I said if only system is wiped, users will still keep all their data and app settings even fingerprint data and the likes... I would 'ever suggest a dirty flash between different builds of the same os even of they are both lineage os... Sometimes the device related adaptations are different and drivers conflict or the likes can arise because of this... At least that's how I experience it

Which Magisk build? Magic hide enabled?
I've never seen this not working on latest builds

 

[Steel01]

You can't go from official to unofficial builds or vice versa without wiping data due to signing key differences. Anyone coming off officials to this will have to wipe and start over. Just like when I release unofficial builds myself.

Hello, everyone,
the August patch day is approaching, so I have now tested updating my builds extensively. I noticed that the 14.1 build is not updateable. It comes, as already described once, to an ERROR 7 error in TWRP.
The 15.1 builds do not seem to be affected. To control this I created a new 15.1 build for testing.

Currently I am planning to change the build image for the 14.1 version to eliminate the bug.

LineageOs15.1 Test Build
Please let us know if it works. And importent is to test it with dirty flash.

 

[The-Saint2k]

as already announced, I changed the build environment for LineageOS 14.1 because of the error " Error 7". I tried several workarounds (adaptation of "update-script" etc), but without success. I deleted the old 14.1 builds and replaced them with the new docker image from jfloff. With this I created two images on different days and could update them without any problems. Unfortunately you have to do Full Wipe otherwise you get Error 7 again, at least with me.

Maybe I'm saying something absurd but the other day I watched Avengers Endgame with MX Player and could use HW+ mode. As far as I know this mode uses mx own framework and the video played smoothly without major battery drain. Does this mean that at least with mx player hw acceleration is working?
