Hi all,

I have a strange issue, I did not found any information how to solve it.

Coming from the Stock rom (latest)

I installed the twrp-3.3.1-0-herolte -> Fine

I downloaded the latest lineage-17.1-20200311-UNOFFICIAL-herolte, and open_gapps-arm64-10.0-nano-20200408

I have to admit that i had some issues with the data partition, which was encrypted.

I formatted it to EXT2 and then back to EXT4 -> Fine

Through twrp then I Wiped Dalvik cache, system -> Fine

Installed the two packages lineage-17.1-20200311-UNOFFICIAL-herolte, and open_gapps-arm64-10.0-nano-20200408 -> Fine, no errors

Reboot without installing the TWRP software... -> Fine

I am now waiting since 2h the booting...

I tried to reset the S7 by holding 1 min the power button, no way

Suggestions?

I will wait till the battery will be empty.. but maybe there is another way..

---------- Post added at 08:27 PM ---------- Previous post was at 08:19 PM ----------

Found the way: Home + Vol. Down + Power

I will try again to install it.. :)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Digger_m:
Dont forget to Wiped Dalvik cache after you install the rom and gapps . That may be why it failed to boot.

Here I posted a guideline (should be the same for LOS16&17): https://xdaforums.com/showpost.php?p=82148025&postcount=2065

Take care of steps 10-12
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Ruller:
I had the same issue.

Don't flash the gaps at the same time with Lineage.

Do it in 2 times. First flash lineage then boot and afterwards flash gaps and then boot again.

Hope it helps.

When crash, to make a reset use only button power and button volume down with 5 seconds. If it doesn't work, connect power in usb and then volume down and button power for 5 seconds.

With me works all the time.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Incineroar:
Been trying it for a few days and haven't had any luck. Turned it on in settings but no dice, even after countless reboots and even a clearing of the cache.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] :
Normally when using Gapps, you always install them both without a boot (and so, the Lineage setup) in between. I installed LOS AND custom kernel AND Gapps package and then booted without any issues.

Issues are probably related to not wiping cache/ dalvik, encryption or other issues. When you have these issues, I would recommend formatting /data, after that wiping all disks, reboot into recovery, copy the packages back to phone and then install. This should always work.

First time boot will take a little longer, but not longer then about 2-3 minutes max..
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] downhere:
Try Pico Gapps instead of Nano.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tyl:
Seems a little loud with distortion at the highest volume.

Still have the original problem of the device defaulting to using the phone speaker (at low volume) instead of the main speaker after a phone call. Rebooting fixes this until next call.

Appreciate you publishing the XML though.

Hi

I have been using 17.1 rom for a week now on my samsung s7. The os is great and smooth, the only problem i faced is that, the speaker output is reduced. that is, the volume is muted (speaker output works well in cosp). Hope you can fix it. And is there a way to improve the ram usage, about 2.4 gb of ram is consumed when compared to 1.4gb from cosp.

Thank you

And keep improving

Yes. I am facing the same problem
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] dadevi:
same problem also with "G930FXXS8ETC1_G930FOXA8ETC1_BTU" fw

Hi,

i have the same problem, i install latest samsung fw "G930FXXS8ETC1_G930FOXA8ETC1_BTU", and then install "lineage-17.1-20200311-UNOFFICIAL-herolte.zip" and Gapps "open_gapps-arm64-10.0-pico-20200403.zip".

The phone dosn't boot, if i install "lineage-16.0-20200311-UNOFFICIAL-herolte.zip" it work fine.

Any idea to fix?

thanks you

i dont know why but still got some problems when i longer not used my phone it stuck and i need to restart

also when i click on weblinks it loads and i need to reopen my apps to make them work again
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Nk_07:
Try wiping (format) your phone before flashing the new software. It might work.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] dadevi:
Hi Nk,

i format ( dalvik /ART cache , System , Data , cache ), install LIN-17.1 + OpenGapp , wipe Dalvik cache and reboot.

Phone don't boot.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Timthedog:
Hi

Just confirm that at least the call sound comes from earphone speaker. To me it seems to happen when I've used the earphone speaker (talked to somebody in ordinary phone). Like you I have to reboot to fix it, but I've also noticed that if I put on the loudspeaker during the call and close the call, the sound remains the same, the call sound comes from the main speaker. So it looks like the problem is that main speaker isn't connected again when a call is closed.

By the way, really nice rom. Thanks Ivan!

So from what I read there are issues related to the audio.

Is there a way to add the necessary blobs in case of microphone noise cancellation?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Mint Julep:
Some people reported issues but I haven't had any.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] votemarvel:
I've done a clean install of the rom and booted it. I've install gapps. My problem is that any app I attempt to download just gets stuck at "Waiting for Download."

There isn't anything else waiting to download and no system updates that I can see. Any advice on how to actually get downloads to work?

I've cleared davlik and cache. I've cleared the cache of the Play Store itself. I've changed around whether downloads are allowed on wifi or data (each option). I've restarted the phone more times than I can count. Downloads will not start.

Edit: Interestingly if I sideload an .apk the Play Store will update it with no issue. it just won't download anything directly from the store.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Kippy51:
My experience with Playstore on ANY of my devices is that Playstore Will display 'waiting ...' for up to 4 or 5 minutes before it actually starts downloading. So normally I just use a backup of Titanium BU or Migrate to install an app and then just let the Playstore update it. When it's a new app you want, you'll just have to wait or get it from somewhere else ...
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] votemarvel:
On my devices the download will start pretty much straight away, I've certainly never had to wait more than a minute, even on my Amazon Fire HD8.

I'll try a complete reinstall and see if that helps, it's not as if I don't have the time during this lockdown.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Digger_m:
I have issues with play store too but I think it's dew to the number of people stuck at home playing on there phones during this pandemic. I'm on a different ROM .
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] votemarvel:
That's certainly a possibility as I know a lot of companies are throttling speeds at the moment to ensure the networks don't crash.

However I appear, fingers crossed, to have solved the problem. It turns out that installing the rom, starting it, then rebooting to recovery to install gapps causes the problem. This time I selected the rom, then picked the 'add another zip' option for the gapps and installed both at the same time.

Now everything is working as it should. It's weird as all the advice I've read in the past says not to install two things at the same time, yet it is the only thing that has worked.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] sooperior:
I'm afraid you have to install gapps right after rom (add another zip, as you say). Otherwise you will run into problems and very likely can only be repaired with a full wipe.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] :
As far as I know and how I do it, the rule is as following;

- ROM and Gapps always first install without reboot in between;

- Magisk first install always with a reboot in between, afterwards you can install ROM - Gapps - Magisk in one run if you want

- When not wiping /system you only have to flash Gapps / Magisk on an update after flashing ROM, /system/addon.d will take care of the rest

[MENTION=4610599]Ivan_Meler[/MENTION]; will LOS17 become available as official with you as maintainer?

Asking because LOS17 is the ROM with the largest user and dev support group and would be nice to come to the point where we get nightly or weekly builds with all development what is done at the moment.

LOS recovery is also in active development at the moment. When you want to keep using LOS and do not care about backups, scripting etc...., automatic OTA in combination with encrypted storage and LOS recovery would be a nice addition when becoming official...

Chrome issues

For me also Chrome is basically unusable unless visiting only one site. When browsing within a few links it hangs requiring long press back button kill. Reopening Chrome the page works ok for a while but very soon Chrome hangs again.

I'm trialling a Chrome Dev and Firebox but can't say yet if same issues. Sure I've seen something about a FOSS port of Chromium, or is this issue upstream.? I've sure I've had this on my old S5 kltedv also LOS 17.1 but I'll have to confirm that.

I saw a solution to the low speaker volume and downloaded the file but I'm not sure what to do with it?

Has a spontaneous reboot. Log is attached.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] 0RF30:
Hi,

I'm using it for almost two days with MoRoKernel 8.1 and openGapps pico, a major issue for me (on g930S in my case) : I have a lot of WiFi disconnections. Same for you guys on g930F ?

I also experienced a boot loop after flashing, I came too late for the down + power tip ;)

I think it was because I magisk + remove encryption right after flashing the rom or something like that, without rebooting between. Anyway my second try I flashed the rom, reboot, configure the phone, and then apply MoRoKernel, which applies magisk just fine. No unexpected reboot/shutdowns for me with MoRoKernel.

I experienced some slowdowns and micro-freezes (mostly when scrolling very long lists), but nothing crippling.

Dark mode looks better than Lineageos 16 unofficial, but not perfect (a lot of daily used stock apps doesn't supports it, for example : calls, contacts, sms...).

Strange thing, android 10 navigation gestures seems not showing in the menu (but I watched a youtube video dated from a month ago where it was working).

Otherwise seems pretty nice and stable already, a good overall experience, and a keeper if it wasn't the WiFi disconnections problem (wich I hadn't on lineageos 16).

Thanks for the work ! :good:

Bug with Build 7 and 8:

You charge the battery to 100%, but you keep the charger still on the phone for several hours. Suddenly the green notification light goes off. It never goes on again (neither by charging, notification, or in the settings menu to set notification colors). You have to turn the phone off and on again to get notified again for new messages or see the charging-LED.

The sound problem is fixed so far, but the old fingerprint issue, some apps (keepass, PayPal..) not accepting fingerprint login, still remains .

There still seem to be audio routing issues:

- Headset mic doesn't work at all in Facebook Messenger video call.

- At the end of the day, the mic for regular handsfree phone calls doesn't work. Speaker does. Mic still works for non-speaker calls. Reboot solves the problem - mic works for handsfree too again.

If you didn't apply permission then you are probably not using it (S7 is applying some kind of defaults).

I have been using the previously uploaded mixer_paths_0.xml file. The loudspeaker call volume is ok but the other person cant hear me at all.

That is, when in loud speakerphone calls i hear myself but the receiver end person is not hearing me. But when switched to normal earpiece call, the receiver hears me clearly.

Let me try this file, and will update you.

What might be causing this problem.
