Hi all I can find about it at this point are the APK filename 1arSo81b5NE6U6Gow7GkEteJ2wdq4vjEc.apk. The version info is 5.1.018.177470874. Not certain but it is possibly from this post https://r2.community.samsung.com/t5/Galaxy-A/use-Gcam-mod-for-better-photo/td-p/284540https://r2.community.samsung.com/t5/Galaxy-A/use-Gcam-mod-for-better-photo/td-p/284540 Note I realized this also has the issue with low volume for video.

If not then this is the problem, you have to remove password and a delete file .. read installation description

Just tried a dirty install of V14 and get a reboot to TWRP. Tried a second time with Gapps just to see if that would work but no luck. I am reinstalling V12 for now.

The phone appeared to run through the boot process but then went back and booted TWRP.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rm43115:
I have the same behavior with a PIN and TWRP 3.4.0 therefore encryption is not useable.

Sailorpito, do you found a solution?

Has somebody an installation with LOS17.1, TWRP 3.4.0 (3.3.1) and working encryption (means accessible data-partition from TWRP and therefore backupable)?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] RickBH:
After trying to go back to V12, now I am locked out of the phone with a "Custom binary blocked by FRP lock". Not my primary phone at least.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] sailorpito:
I haven't tried again with latest build because nothing related to encryption was mentioned in the changelog. Probably is like [MENTION=5592554]Hemuli[/MENTION] said: TWRP version must support hardware encryption. From what [MENTION=6005084]ripee[/MENTION] posted here https://xdaforums.com/galaxy-s7/development/recovery-official-twrp-herolte-t3333770/page159 latest TWRP build is from [MENTION=4610599]Ivan_Meler[/MENTION] updated source, so maybe we just have to wait for the next TWRP build.

Great ROM only LED Notification not working.

Coming from LineageOS 16.0 for S7 build 30 to LineageOS 17.1 for Galaxy S7 build 12 and now 14.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Pilzinsel64:
Hello.

Today I updated from build 10 to build 14. For some reasons on my two devices some apps can't reach the internet using mobile network (both telecom).

Some examples that can't reach the internet in mobile network mode: Telegram, Play Store, Nextcloud Talk

Some examples that can reach the internet in mobile network mode: WhatsApp, Firefox, Chrome

Could you provide me a link to built 10 until you fixed it, please?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] downhere:
[Build14]

Modified mixer_paths_0.xml:

- increased output volumes for speaker, handset

- increased mic input volumes, especially for cam video recordings and video calls

Copy the file to /vendor/etc. Adjust permissions to 0644. Reboot.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Pilzinsel64:
Sorry, but that didn't work. I placed the file in TWRP in /data/vendor/etc (creaded etc folder with 0644) and changed permissions to 0644. I rebooted but I still have the issue with the mobile network.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] downhere:
Use RootExplorer or similar.

I don't know at what point /vendor/etc is mounted in TWRP, but in /data/vendor/... you're at the wrong point.

The folder /etc as well as the default mixer_paths_0. xml already exist, so no need to create any folder, and you have to overwrite the existing file.

This has nothing to do with any network. It's about low audio volumes.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Pilzinsel64:
I have no root installed, that's why I tried with twrp.

But thanks to clarify that it doesn't have to do something with my problem.

However, I just want build 10 to downgrade until the bug is fixed. Does someone still have the build? If yes, could someone provide it me please?

EDIT: I found the official download link in the official telegram update channel.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Incineroar:
Yeah. I had the same issue. Had to use a VPN to get Telegram to connect. However, it randomly decided to start working properly today.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] krege:
Just a kind not relative reminder: you need 0755 permissions for folders. 0644 are for files only. That's not a solution for the issue described but may be one day you will need to create new folder so...

Hello sailorpito, thank you for your assessment, but it's still strange:

If TWRP is Ivan's 3.4.0, why does his LOS16 work but not his LOS17.1 with encryption and TWRP?

Anyway, I think you're right, we have to wait for new builds.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Pilzinsel64:

Hello guys,

First of all, thanks for the awsome content. I have install the 17.1-20200805 build and works very well on my GS7.

By the way, is there an easy way to upgrade the build with the new one (17.1-20200811) without a fresh reinstall ?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] crazydrive22:
Yes. Just flash it via twrp.

You don't need to wipe anything.

(except Dalvik&Cache when flashing is done)

Hi all, I flashed and running on 08/05 stable build's since round a week, running very smooth and well, even if a lot of trouble with ext memory, loss microsd after every reboot, and a touch's lag sometimes.

A little troubles with Android Auto too, sometimes Spotify players starts without voice and just a reboot to starts normally.

as a whole they are just small problems that can be easily solved and do not significantly compromise a job well done as this Rom is, always congratulations to Ivan

Now...what about a dirty flash for the new build?, maybe a need to disconnect before from my banking app and token or goes just like an ota?

Same problem here, it's really annoying. Hope it will corrected, I like this ROM and aims to keep it if possible.

Also I wanted to add there is this one game (Evertale), colors are completely OFF (Very Yellow).

When I put the application in background I can see the "color filter" disappear and the real colors. But whenever it goes foreground again, it's yellow.

I don't have LiveDisplay nor night mode. And other applications seems fine.

The game hasn't a "filter color" feature I checked.

The latest 17.1 Version 14 Does Not Boot SM930W8

After my FRP lock when trying to do a dirty flash from V12 to V14 I managed to use Odin to install the original Samsung firmware and remove the lock. Then tried to install V14 from a clean system with no luck. It just starts the boot process and then reboots to TWRP. V12 boots fine. I have tried the install on 2 phones and the result is the same.

I have had no problem with Ivan's 16.0 on the phones but was unable to get 17.1 to boot until V12 (20200805) and it works fine. Now the latest version 20200811 will not boot. The problem is slightly different this time in that it boots back into TWRP after booting for a few minutes. before the phone just kept running the boot process forever.

I agree it is strange but according to other posters there may be some hardware differences between phones of the same model. No details known though. I am hopeful that Ivan will discern the changes in the lasted build to make it work again for me.

This will not be fixed. The Speaker is directly next to the microphone so you need definitely really good noise cancellation. But the module is a proprietary blob from Samsung. So the only way to make this work is reverse engineering. Everybody who wants to do that is very welcomed. But don't expect that anybody will do this work for you. Because it's a lot of work.

If you search for it, Ivan Meler explained this several times.

Upgraded from Build 12 to Build 14 (dirty flash), but Google Photos no longer works. The app just shuts down as soon as it opens, then a pop says it "keeps stopping" on repeated attempts. Attempts to delete cache and data in the app do not cure the problem. Works just fine falling back to a TWRP backup of Build 12.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] iankelly2001:
Replying to my own post. It appears not to be a ROM related priblem, but a problem with Open Gapps dated 20200814, which I dirty flashed at the same time. Dirty flashing just Build 14 of the ROM and leaving Gapps alone cured the problem.

Hi All,

I added downhere's mod of the mixer_paths to a Recovery Flashable Zip.

It is useful for me so I thought I share it ;)

For those who do not know what this is, it's a flashable zip that you can install in twrp the same way as you install Lineageos, gapps and so on.

It creates a backup of the original file, copies the modified mixer_paths and adjust the file permissions.

Happy flashing!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tha_G:
Hi [MENTION=6129594]john-soda[/MENTION],

I also think you might be confused. What you say is true for when you put your phone in speaker-mode. But we are talking about a regular phone call. This was OK in previous versions of Lineageos.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Zuikkis:
LTE+ means that carrier aggregation is active. That means it is using multiple LTE bands at the same time, to get more bandwith.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] DroidHero2002:
Your zip file can't mount system.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tha_G:
The only reason I can think of is that your system partition is at a different location than mine.

If you can send me your system location I'm happy to include it in the script. To do so you can use 'adb pull /etc/fstab'

For my phone the system_root out off '/dev/block/sda14 /system_root ext4 rw 0 0' line is the important part
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Louskan:

I didn't end up doing this, however I have found a OneUI 2.1 port for our device that appears to have fully working (and loud enough) phone call audio and all that jazz.

With 'all that jazz' you also mean no echo in normal phone calls?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tha_G:

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] padraigdoran:
That's not the problem they are taking about. Sure the speakerphone always has instant feedback for the other side, but it happens occasionally on regular hold the phone to your ear type calls. A reboot always fixed the latter on LOS16.

---------- Post added at 12:04 PM ---------- Previous post was at 11:53 AM ----------

Yes, this is correct. The speakerphone has always been a problem and that is fine. The problem is sometimes the feedback exists on regular calls. Restarting the phone always fixed it on LOS16. I'm not sure but not be related to turning speakerphone on/off over time and then it just stays stuck where the ear piece audio is directly routed back to the mic thus the other side always hears echo.

So, to summarise, this is NOT an noise cancellation issue.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] shaq1907:
I hope Ivan can fix these problems for next builds. Cos I really liked ROM. And I don't want to install original firmware but every phone call I do, receiver complains about it.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] DroidHero2002:
From what I've heard talking on the phone, there's no echo. It's perfect.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chrisrevoltes:
None of my call partners had complaints about echoes. But I did a quick test now, and I had really really silent echo.

(So no problem for me, and absolutely useable)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] downhere:
Are you using default mixer_paths_0.xml file, or did you modify something?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chrisrevoltes:
I didn't chance or modify anything. I didn't thought it was necessary, because my volume was not low. At least I think so ?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] JakeSmith:
+1 for getting this to work, it's actually a cool feature of the S7.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Zuikkis:
These stable releases are really loud, can't have volumes nowhere near the max. I don't understand why people still twiddle with mixer file?

Beta releases were quieter but still loud enough for me, I never felt the need to modify anything. But perhaps in really loud environment it would have been too quiet.

And yeah, never had echo issues either. I think people reporting echo problems should also mention if they are running modified mixer..
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] S4von:
I'm having the echo issue and all I did was just upgrade from lineageos 13 (or 14) to this version and thats it, no further changes/modifications.
