No Luck Installing

This is for general information only. I am not complaining, just want others and Ivan to know that there is some sort of item that is not allowing the boot to complete on some versions of the S7. I hope to be able to use 17.1 eventually when it is the new stable system so it would be nice to get the phones to boot.

I have tried installing 17.1 on my S7 (S-930W8), unsuccesfully since the first release. Wiped everything including data reformat, installed 17.1 and GAPPS pico. The install goes cleanly with no apparent problems other than it does not finish the boot process. Left the boot run for 30 minutes this time. before shutting it down and collecting the logs from TWRP (attached). I am wondering about burn-in of the boot animation on my screen because it has run so much.

I have another identical S7 (daily phone) that runs 16.0 with no problems. I tried installing 17.1 on it yesterday with the same bootloop result, so I expect that the problem is not the particular phone but with something in the components that is different from most.

I have tried many times with all of the 17.1 versions, tried all of the GAPPS that I could find, tried not wiping everything, etc. I have other Samsung phones and have not experienced anything similar with them. I have noticed that there is no boot.prop in this Lineage 17.1 or I would be looking there to see if I could see what might be wrong.

I have noted this previously and I tried all of the things suggested at that time with no change in the resulting bootloop.

Thanks to Ivan for keeping the phone current.

Thanks for the detailed explenation. I did put it in the right folder (as it was greatly explained here) but I don't know how to apply permission (my device is not rooted if that matter)

if someone could kindly explain how to do it, I will be happy to try the latest version that was just posted and report back

thanks in advance for your willing to help!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Nk_07:
Hi,

Being not rooted is ok.

Hope you have followed the steps in the twrp recovery menu mentioned before.

After replacing the file (mixer_paths_0.xm), click on it. Certain options will be shown, one of them being chmod.

Click chmod and type in 644 in permission and click enter.

Then reboot your device.

After doing this, provide your feedback here.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] mustardman29:
I did this on my G930W8. It was fairly straight forward. Lots of guides how to do each step but these are the versions of software I am using in the order they were installed.

* Odin v 3.13.1

* twrp v 3.3.1-0.img.tar

Then, install the following using twrp.

* Lineage v17.0-20191008-UNOFFICIAL-herolte.zip

* Magisk v19.5_c42a51dc.zip

* BiTGApps-arm64-10.0.0-v0.2_signed.zip

---------- Post added at 05:35 AM ---------- Previous post was at 05:31 AM ----------

You root the device using twrp, after you install LineageOS. You just install Magisk the same way you installed LineageOS, from twrp. There may be other ways but I think that is the most common and recommended way.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] RevinEvan:
Ok thx I downloaded everything but magisk once I download that I'll give it a shot.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] mustardman29:
You need Magisk v19.5_c42a51dc.zip or (presumably) newer. My phone would not boot with older versions of Magisk.

Flash & flashlight not working. Problems with audio. I grabbed a Matlog ...also some errors on startup ..boots in like 20sec ....really quite smooth
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] KevMetal:
Here is the Matlog I could grab . I had to flash back 'cos phone is my daily driver .
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] KevMetal:
Boot into twrp

"Wipe"

Install Rom

Install Bitgapps

Install Magisk

Reboot

It will reboot once (dont worry)

It boots to system very quickly

You can dismiss the error on startup

Be careful and make sure to install Magisk 19.5 or later ..anything lower gives a loop ....

I am a person who would rather read than ask, always solved problems with custom ROM in this way. So this is my first post, which is to say that [MENTION=4610599]Ivan_Meler[/MENTION] is the man! Congratulations and my huge thanks for making the S7 a Highlander !!!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] CapSel:
I wasn't aware that S7 had such sensor like heart monitor.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] KevMetal:
Yes friend, look next to camera under the flash ....

Or look at Google for more information or install an application that tells you your hardware when you are on stock
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] KevMetal:
Here we can see it working on stock but on custom rom it says "cant connect to sensor"

And NO it does not use camera flash like with cheap imitation applications ..it uses laser ..like in hospital

Flash burns finger and is not accurate ......
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Michael1986:

It's quick support like this that makes me proud to cling onto an S7.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] psyalemao:
So the list of bugs and not working features till now:

-Heart rate sensor

-Fingerprint sensor

-GPS ? (for me it's working fine)

-Software backed video playback

-Audio inside games doesn't work (for me at least)

-Vulkan API (stock nougat and oreo have it, but I don't think [MENTION=4610599]Ivan_Meler[/MENTION] is gonna implement it since mess with mali gpu drivers sounds trouble)

-Settings>System>Status bar>Battery percentage next to the icon doesn't work

-To change system colours and style you have to go to the developers options instead of Settings>display>style

-Live display doesn't work too, for blue light filter/set the color temperature to display

-CVE 2019-2215 Vulnerability? https://hernan.de/blog/2019/10/15/tailoring-cve-2019-2215-to-achieve-root/ and https://github.com/marcinguy/CVE-2019-2215/

-Some apps will auto rotate the screen even if the option is toggled off when using the phone in landscape mode

-Random freezes and reboots

Battery status doesn't get displayed

Hi, good job!

Except the known issues I recognized that even if I change the setting the percentage of battery doesn't get displayed in status bar. The battery icon doesn't change too after changing the setting. Fixing this would be very nice!

Thank you very much!!!

Hey,

Is there a way to improve ram usage or ram management.

My phone had forced restarted while using, couple of times.

When compared to cosp which only consumes about 1.4gb.

Hope it can be improved
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Zuikkis:
Are you sure it's not just cached data? I'm running MoroKernel which has the convenient MTweaks -program, it's showing over 1GB of "cached" memory.. That should release automatically if running out of RAM.

Moro seems more stable than stock kernel, btw.

Hey guys, currently running LOS 16.0 on 2x heroltes (wife & father-in-law's). Would you all say 17.1 is ready for a daily-driver for someone else's phone? Or does it still need a few tweaks? The only issue we really have with 16.0 is the speakerphone echo since Ivan can't use the Samsung proprietary noise-cancelling. I assume that's still an issue in 17.1? Thanks!

My phone recently crashed and restarted while i was just watching videos on youtube. I dont know why.

I have had issues of phone hanging on normal usage and had to force restart the device.

Do you use wired earpieces or Bluetooth?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tvfan1:
I am referring to the actual volume coming from the device itself- all other settings (rings, notifications etc) are very loud and can be adjusted to a lower level. Call volume is at the maximum level and is very very low (I have to really push the device to my ears to hear and yes,my hearing is fine :)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] downhere:
OK... adjusted earpiece/handset output levels.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] vand3537:
what value(s) do I need to adjust to bring up the speakerphone even more?

and also to bring down the keypad tone volume
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Digger_m:
The only sergestion I can think of is to reinstall the OS you had before and see if you can restore from the Google backup. If that works then boot to recovery and backup data reinstall this OS restore the recovery backup. It may work.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tvfan1:
Thanks, I will install, run it in the next day or two and will report back

Thanks [MENTION=3146909]downhere[/MENTION] for your support and responsiveness

Update: Earpiece volume is MUCH better in the new XML file but only when set to Maximum. if you can adjust it to higher level it'll be great (so that the current max will be 80% in the new scale (needed for noisy environments) , I'll test it as soon as you'll post a new one. Thanks again!

Guys, I'n still on Superman ROM 3.0.0 (adnroid 8 oreo) and last time I updated to another ROM (9 pie) it wanted to format my SD card which is a no-go for me because I linked like all my apps and the whatsapp-folder to the SD-card.

How can I prevent it from doing this?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] xyloth:
As always, thank you Ivan for maintaining LOS for the S7!

One Bug that i've already noticed in Build 7 and that is still happening in Build 8 is that sometimes i can't take calls.

The Phone would vibrate (can't say anything about ringtones bc i have my phone on silent) but the typical Calling Screen where i can accept or decline the call just doesnt appear, so theres no way to take the call.

I have the feeling it happens more when i have the phone already in use with screen on, but thats just a theory. I think it has happened with screen locked and dark too.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] downhere:
[Build 8 - mixer_paths_0]

Changes to previous version:

- increased earpiece/handset max volume level

- decreased speaker max volume level
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] downhere:
In the output volume stage look for

AIF4TX1 Input 1 Volume

AIF4TX2 Input 1 Volume

If you ask me, the speaker level is already too high... I use max 50% volume .

... and don't blow your speaker or ears... ;) The risk is all yours.

I haven't played around with audio routing, so I can't say anything about keypad.

wifi not stable

First of all, thank you for maintaining Samsung Galaxy S7!

I installed the rom (lineage-17.1-20200423) on my S7 yesterday. Flash rom, wipe cach and davlik cache, flash gapps nano, flash cache and davlik cache, reboot; it takes some time but finally S7 boots.

So far everything works. What I found is that the wifi connection breaks as soon as the wifi is not visible. In the view of the available wifi's you can see a constantly refresh. the first time refresh after you have set the wifi to invisible, it disappears ... is there a fix for this?

Hi guys

Firstly i'd like to say a big thank you to Ivan for all his hard work. I'd also like to thank downhere for persevering with the volumes, much appreciated.

I have noticed something with the call volume tho. If i open the volume panel and move the call volume slider up and down, the 'beep' noise gets louder and quieter, all good.......but when you're making a phone call and you move the call volume slider up and down it doesn't work, the persons voice stays the same volume. Just wondered if anyone else has this? Cheers

Hi Tobias,

thanks for the investigation. I wait since LOS 15 for a possibility to use my eID.

I checked the amendments with the "AusweisApp2". The app did not complain about the not supported ext. lenght of the NFC. I was able to enter the pin but run into a "NFC reading error" at the end. It seems, that the AusweissApp2 was not able to read all data out of the NFC chip.<

ADB logcat attached. If you need more / other information please let me know.

I am loving this ROM on my very dated phone, it is working beautifully for the most part. For the little issues I have I did search the post but my search fu mustn't be very good.

My minor issues are:

- I can never see the lock screen, I press the power button and it wants me to unlock my phone, I press the home button and it wants me to unlock my phone. Is there a way to just look at the lock screen?

- The phone locks whilst on a call, how do I stop that?

- The included camera (Google) did not work in selfie mode would just crash, have replaced it with open camera and is working fine.

- I have had intermittent issues with the Speakerphone, it mostly works, but when it doesn't it is too quite and I cannot hear the other person.

Again great work, loving it!

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Zuikkis:
I had initially stability problems, phone would sometime freeze randomly or restart spontaniously.

Then I flashed MoroKernel, which seemed to be much more stable. However it was not very smooth, animations and games looked "jumping".

I then dirty-flashed this LineageOS again, to overwrite the kernel back to original. I did clear cache+dalvik of course. And guess what, now it is stable and smooth. So apparently there was something wrong in my original installation.

I am using the pre-installed camera and it's working fine. Also I never have had audio problems so I haven't touched the xml people are talking about.. :)

My only real problem, sometimes I lose the wifi. It just switched off and cannot be switched back. Reboot fixes it, and it can take several days before it does it again, so it's not a that big deal.
