Start from scratch making a CLEAN install.

Here a detailed Instruction:

========================================================

1. In your ROM, go to Settings -> About device. Tap 7 times on Build number to enable Developer options.

2. Now go to Settings -> Developer options. (above About device)

You need to enable OEM unlock, otherwise you might end up with boot problems or be unable to flash later on.

3. Extract Odin to your computer.

4. Install Samsung Mobile Phone Drivers for Odin to find your device.

5. Download a .tar image of TWRP for herolte.

6. Reboot your device into Download mode. To do this, select reboot from the power menu and hold the [Volume Down] + [Home] buttons while your device reboots.

Once you reach the Download mode warning screen, press [Volume Up] to continue.

7. [Optional] Install latest Bootloader / Modem firmware:

Open Odin and place the Bootloader in the [AP] and Modem in the [CP] slot.

Disable Auto-Reboot Option, then press [Start].

8. Open Odin and place that TWRP tar file in the [AP] slot.

Disable Auto-Reboot Option, then press [Start].

9. Hold [Volume Down] + [Home] + [Power] to get out of Download mode and immediately swap [Volume Down] to [Volume Up] (continuing to hold [Home] + [Power]) when the screen blanks.

If you don't see then TWRP boot splash try again from step 6.

10. At this point, you will reach the screen asking you if you want to allow system modifications.

By swiping right, you will trigger dm-verity, and if you don't follow the next step you will be unable to boot!

11. After allowing modifications, go into Wipe and choose Format Data option

(no need to format differently and then format back again)

12. REBOOT back into TWRP recovery again using the option in the reboot menu

13. Download the latest ROM for your device.

Without exiting TWRP, transfer the ROM zip to your device over MTP* and flash it using [Install] in TWRP.

14. [Optional] Download the latest GAPPS for your device.

Without exiting TWRP, transfer the GAPPS zip to your device over MTP* and flash it using [Install] in TWRP.

Important: Flash Gapps and Mods right after Rom Installation, no reboot in between!

15. Go to [Reboot] -> [System].

12. Wait 2-5 minutes for your device to finish setting itself up.

LOL. I have given to try to "make emergency call", write a random number, and then now it works.

[MENTION=4610599]Ivan_Meler[/MENTION] Now we have to use video conferences. Tried skype and jitsu. Joining the conference the members complained about chirping sounds. Myself I do not hear it. That is only happening with my device. So I assume it is LOS related. Are there still audio issues?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rdelmont:
that's the same behavior you have with whatsapp audio messages, very old topic about mic noise cancelling features, which for S7 so far are not open source. Btw I lately used skype, jitsy meet, google duo, whatsapp video calls and others and yeah, your mic might be crackling a little bit still it's usable and does not impact the call per se. Think that's a good compromise, anyway... Unless someone starts cooperating with LOS team by writing open sound drivers for S7 with open noise cancellation features as well.... But that'll never happen.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rho-bot:
I have a question regarding build.prop:

- Why is the rights for this file set to 600, and not 644? Is there a reason behind?

Another Question regarding Camera2 API (I don't want to start a discussion about cams!):

- Could not find "persist.camera.HAL3.enabled=" within build.prop. Is the API supported by this ROM? Is it enabled by default, or has the tag to be added?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] OllyFunkster:
It is supported but you have to enable it either by patching the zip or by flashing a camera2 enabler zip. After that (and installing e.g. microG) gcam works (more or less).
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rho-bot:
Thanks for the quick feedback. Maybe ZIP is the better choice, as is persists ROM updates.

Will try this one from CM: https://www.cyanogenmods.org/downloads/camera2-api-enabler-zip-file-download/

Do you know if GAPPS (GSF) is really needed for running the modded GCams (e.g. IDan)?

I prefer to keep the system G-free ;)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] OllyFunkster:
You need something, either gapps or microG. GCam won't run at all otherwise.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Athasgames:
Already had problems once... (lol)

Hey, Just wondering if the download links and everything are up-to-date.

Also, just to be sure, because I have had this problem already, this is compatible with the Snapdragon version of the S7, correct?

All the builds of Lineage that I have tried, I find out can only be installed on Exynos devices.

Also, if there's anything I need to know upon installing this that people have found through their experience with this build, I would greatly appreciate you sharing :)

Does this have root built in or do I need to do that myself? Or is that even possible on Snapdragon devices?

Thank you, Ivan_Meler, you are amazing :D
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rho-bot:
The DL links are working fine.

This ROM is for Exynos devices only! Thread is located under "Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveries, & Other Development"

The reason you will not find ROMs for Snapdragon devices is that for these devices the Bootloader is locked, and you cannot even use Custom recoveries...

New build with april security update is up

Here is a brief changelog

- Merged April 2020 security update

- Imrpoved wifi speed while bluetooth is turned on

- Imrpved dual band and background scan support for wifi

- Sycned with LOS source

Los 15.1 and 17.1 build will be up soon, 17.1 is still in process of being completely rebased which is taking time and due to curent situation its taking longer than expected as i had to deal with some stuff in personal life too, Big thanks for everyone who supported this project in past as without them this project wouldnt still be alive

Hey

How cann i simply update my LOS 16 built 26 to build 27?

Is there a way to flash and keep your phone settings, aplications and personal data? Or you must flash the new built and setup the entire phone again and install all aplications?

Thanks and best regards!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Beanvee7:
You just dirty flash, i.e. you just flash the new zip via TWRP and don't do any wipes (you can optionally do cache/davlik). Basically the equivalent of an update.

Bluetooth range and quality

Hi! Thanks Ivan for April update.

I have updated and it runs fine, but I have a Bluetooth headset, Jabra Elite 25e, but the range and quality is not good, stuttering sound. Can you look into this?

I have tested Lineage 17.1 on Samsung s6, and on this device my Jabra is working better.

Thanks!

Wbr Roger
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] OllyFunkster:
Latest update installed, seems fine. Bluetooth audio working fine with my Jabra Evolve 75 on a cursory initial test. Thank you Ivan_Meler!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Roger-lindahl@hotmail.com:
Hi OllyFunkster!

Good that the Evolve headset works, it is highend. I came across a Plantronics Legend mono BT headset and the range is very low, and stutter is present. Tested with Lineage 17.1 and Samsung s6 and it works on that device. I guess I would have to wait for 17.1 for Samsung s7?

Bugs on Build 03.11.2020

Hi, I'm using LineageOS 16 for one month now. I really love this ROM but encountered the following problems:

- Camera stops working without any reason (front and back)

- Apps are closing without any info about the close

- Call volume is low (can hardly hear the other person), even on speaker mode

- Other caller is hearing himself double (some type of echo)

Is someone encountering these bugs too or have any fix for this?

Thank you in advance for every answer!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] libove:
Google Camera v5, or OpenCamera with Camera API v2 enabled

Hello andreas21042,

I found it necessary to add a different camera - com.google.android.GoogleCamera version 5.1.018.177470874 which I found online as GCam_5.1.018.177470874.41362666__SG7Exy_V8.2.apk (file is 39.296.446 bytes).

Aside from that, OpenCamera also works (the normal copy from the Play Store) AS LONG AS you enable the Camera API v2 in OpenCamera settings.

(The reason I chose to go with the Google Camera, despite that I personally prefer Open Camera, is that I'm unable to get Open Camera to be able to take pictures from the lock screen without entering the PIN first).
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] pineloko:
I have had this ROM for a while now and as with all Lineage ROMs I'm getting random reboots every few days.

But since installing the latest updated I've gotten ~5 in a day. Few times a week was tolerable but this is just bad.

Could my dirty flash have anything to do with it and should I bother clean flashing again or? (It was recommended here to dirty flash)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] ScoobDoob69:
Which GApps variant should I be using?

I tried the "super" variant and my S7 did not boot for hours, it was just stuck on the lineage loading animation. My phone just got really hot and the battery was almost dead despite being plugged in.

I'm downloading and going to retry installing with the "full" variant to see if that works. But, if there is an ideal variant others seem to be able to boot up after 20 minutes, I'd like to know... I'll keep trying to search too :)

Thanks

Did u wipe cache / dalvik beforehand before doing it? I've dirty flashed upgraded and have had no reboots on both versions
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] pineloko:
No ????

Is it too late if I do it now?

Or wipe just cache/dalvik and then flash it again?

I thought about it but deemed it unnecessary as someone on this thread said "just flash it in TWRP"

Also strange that you're having no random reboots ever, I've had them regularly on pixel experience, havoc and here. I just assumed it's what AOSP does on the S7
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rho-bot:
No. Just go in TWRP and delete cache/dalvik, no need to reflash rom (although it may not hurt...)

For me, the Roms run solid without reboot, only some flaws wit LiveDisplay and LED notification

Hello

I've compiled the kernel but do not know how to flash the dts and dtb along, could anyone help?

I haven't seen these files in my previous ROMs on other devices, so sorry if it's a tiny bit offtopic.

I actually wanted to apply the HID patch on the new version of this ROM, so that's why I need to compile it.

Edit:

It's fixed, I just need to use AIK. Thanks
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] OllyFunkster:
No random reboots here, only the occasional one when using GCam which seems quite unstable at times. Bluetooth also works fine with my cheapo Anker Soundbuds Curve.

The notification LED still stops working after a while, and the night mode colour is still hilariously bad (I assume that this is a general LineageOS problem) on the latest build.

The lockscreen message (one can set in Settings -> Security -> Lockscreen) does not appear on the actual lockscreen.

Any help/advise? THX
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Roger-lindahl@hotmail.com:
Hi!

Maybe it is because the headset Anker Soundbuds Curve uses a different soundcodec, from what I found on the internet, codec is: "APTX". I have checked that mine Jabra Elite 25E uses soundcodec "SBC" under developer options. I am only guessing here. I have uploaded my logcat (se link below) where I have stuttering in my headset, between the time 20:02 - 20:04 (Spotify app). The bluetooth device ID is: Device ID: 74:5C:4B:13:06:C2. https://pastebin.com/PKf8rL63

Hey there. Im using this rom for a few days now and it's awesome. I just have a wierd bug. i can't get the fingerprint scanner to work. It's stuck at the "Locate you scanner" Screen, I can't do anything, nothing when I touch an no next button.

Any help for that?

Thanks!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rm43115:
At first I had the same problem and thought my finger scanner is broken (because I had ordered a new S7 from China).

I got it by trying it out, i.e. tried again and again (including pressing the home button) ... at some point it worked ... from that point on I had no problems.

Sorry that I can not provide a direct and easy solution!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rdelmont:
For me fingerprint worked out of the box... Really, no issues. The only thing that I'd say is that when I enabled that I was not using Magisk but LOS root instead, but It might be just coincidence.

Not sure if this is a bug, or has been mentioned elsewhere; not sure how to search for it...

When nighttime "blue shade" is on (~2900K temperature) any blue on the screen gets super-bright/saturated. It's clearly in the display somewhere because if I take a screenshot and send to another device, the colors look perfectly normal.

Anyone?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] inoxa:
Yeah you're not alone, same thing happens for me.

I haven't seen others mention it anywhere so I'm not sure if it's a LOS16 issue or specific to S7?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] OllyFunkster:
I've mentioned it. LOS16 on my S4 Mini Plus doesn't do it.

I started digging into the code that's responsible for doing this colour adjustment but the trail went cold before I found any actual maths - I think Lineage just sends a colour temperature to a hardware driver somewhere, and I guess that hardware driver is doing the sums wrong or adjusting the wrong parameter in the display hardware.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] inoxa:
My apologies, I obviously hadn't looked hard enough.

...and good on you for trying, is beyond me.

But I have LOS 17.1 (and previously 16.0) on my Nexus 6 (Shamu) and it doesn't do it. Neither LOS 16.0 on my Galaxy S4. So it's specific to herolte.

Led notification gets bugged

I installed lineageOS on my galaxy s7, everything works fine. The notification led for some reason gets bugged after some time, yesterday the led was blinking normally, (yes the blinking is setted to on and everything). But today i experienced that even while changing the led color and having a preview, the led wasn't showing up. I had to reboot the system to fix this.

Hello, is it possible to get a link to download build 27? The 28 one is buggy on my phone: audio is completely fragmented on one bluetooth speaker (another BT speaker is working fine).

I cleared BT cache, unpaired and re-paired the BT speaker, without any good result.

The BT speaker works well with another device paired.

Or if somebody has something I could test to get rid of this fragmented audio…

That is probably not a build 28 problem, try a clean install starting from a twrp wipe. You can make backups so that even if the bugs didn't go away, you can revert back your data.

I've upgraded from 27 to 28 without any new bluetooth audio problems arising.

Hey Ivan thanks a lot for your hard work !
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Zera01:
THANKS Ivan for this great work!

I really love it, but I have two problems.

1. Playing audio in background ist stuttering from time to time when the display is on. If display is off, all is fine.

Tried different apps. No help.

2. I can't control display colors. All LiveDisplay settings have no effect!

I am not happy with my contrast and saturation. It's all too dark and saturation is unnatural too high.

Tried different apps. The only one that worked for saturation is called sa2ration. I reduced saturation from 1.0 to 0.66. Colors look more natural now.

Still having the problem with the contrast. Dark grey and black is nearly the same. My brightness is at 95‰

Anyone knows a working app for color and contrast corrections?

Kcal is not supported by this kernel, right?

Test pattern for contrast and brightness.

[IMG="test pattern"]https://www.burosch.de/images/zz_492.jpg[/IMG]I can't see differences in black... The 4 darkest grey boxes are all black.

Edit: I found a LiveDisplay enabler script, which works.

Now I can adjust colors and nightmode (blue filter) is working.

Install with TWRP in recovery mode.
