LineageOS is an operating system for smartphones, tablet computers, and set-top boxes, based on Android with mostly free and open-source software

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.


I've built this operating system with select userdebug .

It's unnoficial LineageOS17.1 for Galaxy S6 (ZEROFLTEXX)(SM-G920F).
I strongly recommend to perform a backup of your current rom before installation.

Hi gapps included in ur ROM?
And can I install other boot.img files? I have tried that.
I know it won't work but a question..
Still will download and test..

Almost everything works except Volume control while calling the same problem on 17.1 ROMs but everything else works fine I can just adjust volume from my file I'll just patch it with profile text lol thanks.. Very nice work ??????☎?

 

[Johannesdavidsen]

Yup this is my other account here.
and only on my laptop..
But i managed to get my favourite Kernel to be installed thanks to this beautiful work and kernel i installed is enforced and my ( favourite Kernel )
is pemissive so it depends on kernel and i don`t give a f... nice work man.. Thanks..
I can`t say thank you enough because i have tried other roms to get my thing install`d lol THANK YOU..

 

[AnErare]

Are there any issues with audio on incoming or outgoing calls? Did you manage to get both the front and back cameras working? Most other custom roms have a combination of issues there.

EDIT: I just noticed Johannes did mention a call volume issue

 

[L1feGuard]

add support 925f zeltexx pls

EDIT: I just noticed Johannes did mention a call volume issue

It has that same sound software problem.
But I think everything else is working. I try to restore boot from my previous backup it works but (sim not showing).
I try to restore other backup stuff but, of course did not working.
But it amazing i can use other kernel just by restoring from backup
They might be better ways to use other Rom's kernel.
I will use it like that soon without any possibility to have Sim card
I like my kernel lol..
This phone ( I ) use is near death so let end it Battery life with that Kernel I use... Lol
I'll test permissive only file download soon and try to restore boot from backup. And see
Or I should try to install Boot.img from the zip

Edit: It didn't work but first with enforcing SE always boot up no matter what i restore from my backup boot/cache/data/efs. I didn't test other rom enough yet.
And I will test more soon for fun..
Btw.. I got 3 mods installed on my backup so I'm gonna have to test new install's from all rom's and re-test from all over.. Or from start lol..
I want to know you guy's have any mods to make system faster or battery-friendly mods
I have added some text to build.prop and installed 3 mods I think. Maybe not all installs patches:
First for Fullscreen Gesture (Q) from Magisk modules.
Because my ROM is old and I removed some system apps.
And then I install kernel mod from this site. Lol (kTweak) it can be seen from Magisk
And 1 patch from here XDA post few days ago
And my build.prop tweak it looks funny:

ro.min_pointer_dur=0
ro.max_pointer_dur=40
wifi.supplicant_scan_interval=9000000000
windowsmgr.min_events_per_sec=0
windowsmgr.max_events_per_sec=60
debug.sf.nobootanimation=1
logcat.live=disable
ro.media.enc.jpeg.quality=100
profiler.force_disable_err_rpt=1
profiler.force_disable_ulog=1
ro.mot.eri.losalert.delay.delay=1000000000
ro.kernel.checkjni=0
ro.kernel.android.checkjni=0
persist.android.strictmode=0
ro.config.nocheckin=1

That it if I didn't forget something
And make Settings less cpu hog or how to say make it CPU friendly lol .
1 more thing I have edited Sound mixer from System files
You can search it on my comments on my other account Johannes Davidsen
On Enezusun's 17.1 Lineage Os Multitarget rom
I couldn't post attachment's so I have to copied text
That all.
Here, there are 3 sections i think : https://forum.xda-developers.com/showpost.php?p=83187603&postcount=310

This ROM has still the sound volume issues, but camera is working here, right?

This one https://github.com/enesuzun2002/lineageos-ota/releases (28. Feb build) has working call volume and also working cameras, right?
The 13. April build of it has sound issues again and fast battery drain?
It's hard to keep track of what's working in each ROM build and what's not.

Why don`t you test them by yourself sometimes same device have different problem with same rom and it is very confusing..
For me all of them have working camera and all of them have, calling sound software problem that i just fix by editing sound file..
Have a nice day..
And yes cam is working on this new august build,
same on sound problem too

For me cam is working, only problem i so is the same software problem when trying to lowèr volume on calling or say on earpiece i`ll just replace sound file with the file i already have edited but it is very low.
You can test it i have commented on Enesuzun`s rom i think it started on page: 31 or 32 there are 3 comment sections i use for text

good

 

[schlombie]

Nice work. Thanks for that selinux enforcing rom. Unfortuately I cannot enable encryption. After set in security settings the boot in a bootloop.

I have exactly the same problem. And are there any other things to do to make the device even more secure? Some Modules ?

 

[schlombie]

My dirty trick to enable encryption was, I installed e rom for the device. Enabled encryption without a pin direct after the installation.
Than I installed the 17.1rom without format data. Only wipe system, data and the caches. The rom boot up allready encrypted.
I only set a pin and thats it.

 

[progamfa23]

hello or a little problem with the download link, just don't have the link, can you try s create a link on mega or google drive ???

to another thing i wanted to say, i am surprised that you are creating a rom for android 10 with the SElinux Enforcing, i wanted it a lot to increase the security, but the problem of this that lead to lose some battery, however i am interested to try this rom on my samsung galaxy s6 SM-920F i just have to understand where the link lol.

in my opinion, however, thanks to the rom with the SElinux Enforcing maybe this rom could become official if you want, and put on the lineage os website, but honestly I don't know how it works, this is just my opinion

I wanted to say another thing, that second it was better to do lineage os 16.1 because it is much more stable for this device, in fact existing official resurrection remix with android 9 that I use that not a bug, or tried official evolution x with android 10 but the problem of the wi fi that turns off and that you can disable it on the lock screen, and this and these 2 are a big problem, and that problem also exists in the lineage os 17.1 of another creator, everything to see if in the future when there will be lineage os 18.1 for this device with android 11 maybe the wi fi and lock screen security will work prevent you from turning off the wi fi from the lock screen


i am using google translator, hope the translation is right

 

[AnErare]

A wipe basically formats a partition, so what exactly do you mean, that you wiped the encryption too?

I'm sure this ROM doesn't support whatever encryption /e/ may support that you're suggesting.

But maybe I've got this all wrong

Thanks. It works for me.
I have one problem with this rom. Bluetooth headphones don't work. I can connect to the phone but the conection is unstable and stop working. it something like: connected, not connected , connected, not connected each 10 seconds or so.
Sorry for my English thanks a lot for your attention.

Someone please can explain to me step by step how do this trick for enable encryption ?
I've tried 6 times and nothing works maybe I'm misleading something.

Hi, i just wanted to ask how you compiled lineageos for the s6. I tried to compile los 17.1 with the files provided by enesuzun and have massive problems with lunch detecting the files. Many are missing and even if i collect all it just acts weird. Since enes provided many working images these file should work to compile, don't they? Do you know any good tutorial? Most of them are only either for official builds or completely new unsupported devices.
Thank you in advance.

What gapps? opengapps is provided for 10.0 only...
I have LOS 16.0 from enes but wanted to give it a try.
After wiping (system, cache, data) and installing this rom with opengapps 10.0 and magisk zips,
the reboot stucked in boot loop.

For LOS 16, which is Android 9, you have to use the OpenGApps for Version 9. You can download them at the OpenGApps Project Homepage.
Try one step at a time when flashing or try the newest version from enes.

Oh, I mean: what gapps does this ROM (17.1) need? (with opengapps 10.0 I got into bootloop)
