Sorry, confirming this for your 2nd build, plus turning off only from TWRP didn’t even work, It had booted back into TWRP and was still in recovery mode, when I grabed it just now.
Now I could turn it off, by long pressing VOLdown & OnOff – it just shows the loading annimation now
just refer to
https://forum.xda-developers.com/t/lineageos-19-1-android-12l-signature-spoofing-ota-updates-for-s7-exynos.4368995/
and the sources are here
https://github.com/orgs/8890q/repositories?type=all
I’d put the device, kernel and vendor data in the respective folders. Then did apply the patch
https://github.com/8890q/patches
which was successful.
After this is run breakfast / brunch and build went fine. Sorry I don’t have the logs any more
I’d tried now also a T build but got this error which I cannot address. Maybe someone can help?

The error suggests these things have not been pulled into your environment for some reason. As a first step you might look at lineage_herolte.mk. On my “samsung_device.mk”, this is mostly about these tasks:
# Inherit from those products. Most specific first.
# Inherit common Lineage phone.
# Set those variables here to overwrite the inherited values.
So you might look further into
$(call inherit-product, $(What you find here)
Secondly you get clues, by looking where the libs come from – for instance I recognise libOMX.Exynos.AVC.Decoder from a Samsung__proprietary-files.txt so this one might be some wrong / missing vendor source.
Thanks. Got it! Was one of samsung slsi linearo packages… so lets see how this proceed
Alright. Build was successful. I applied the patch and let see if it works. I assume the chances are low since R and S did not work but let’s see:

This is Ground Control to Major Ron
You’ve really made the grade
MVB of the Month Aug/Sep here on the forum => @ronnz98
BTW: Always setting up WiFi, scanning a QR code
What do you mean with that?
So does it work?
Yes, it’s a tripple check in one go WiFi, Camera, QR scanner 
Just now, I also used an app password QR code from Murena.io to set up Nextcloud app that way, worked too.
ok great. I presumed that it might not work. Did a build for the S7 Edge now too
You might check out the scripts within docker here https://gitlab.e.foundation/e/os/docker-lineage-cicd/
You might try this method to check out the underlying repo build scripts.
$ mkdir Build_Primer
$ cd Build_Primer/
$ repo init -u https://gitlab.e.foundation/e/os/releases.git -b v1-t
Downloading Repo source from https://gerrit.googlesource.com/git-repo
Your identity is: make-nz <you@example.com>
If you want to change this, please re-run 'repo init' with --config-name
repo has been initialized in ~/Build_Primer
$ cd .repo
$ mkdir local_manifests
Write / copy a one project manifest; SaveAs .repo/local_manifests/build.xml

Now you have two folders with stacks of scripts and READMEs without the distraction of trying to build a ROM ! 
@aibd This is great thank you!
@ronnz98 as I have not just one S7 and S7edge, I would like to build for them, too.
I’m still wondering, what the missing parts were, which stop it from booting!?
I dont know. I’m not a developer. But the T version works right?
But you know, what you changed before!?
I did not change the build. The respective sources are different for R,S and T for this device. The patch can only be applied on S and T. To understand why it does not boot one need to debug
So, now I got it, I think… I wasn’t sure anymore what was in the builds that did not boot and thought you fixed something in the same version.
It’s kind a safe to assume something did not get back ported for version R…
And in any way, having the newer Android version run on the S7 – with blueooth working, better WiFi and better battery life – is awesome!
Hope we will not here a:
This is Major Ron to Ground Control
I’m stepping through the door…
Thanks again @ronnz98
Hello all,
@make-nz , @anon29344687 do you still use your S7 with the T build from @ronnz98 ?
If yes can you confirm me that your phone is working fine or if you found some issues ?
Thank you for you answers.
