What i did was download the update on the phone : click on the 3 dots next to the download update button and paste the link on your browser, when you finished downloading reboot in recovery and simply install it. Hope i helped!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] hippo66:
The other way - copying the download URL, downloading it and trying to install manually with TWRP fails, too. Its a ZIP signature error then (from TWRP message).
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] SpinStudios:
I don't know which s7 model you have nor the twrp you are using but i'm using the latest official twrp 3.7.0_9-1 without any changes to the settings on a g930f herolte. Also OP said a few messages above that if that doesn't work you can disable signature verification in twrp.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] gabriolinari:
hi guys, jumping in here with a sort of related problem.

@Ivan_Meler

Today had the notification for the 16 June OTA update to 19.1 from 19.0 - from system menu - update would say signature failed. Read a bit here and I thought no worries! Downloaded the .zip from the GIT link, flashed it in TWRP there, it went through and now phone doesn't start completely. I had TWRP, root and magisk, overall running OK.

It goes past the lock screen (encryption), and it recognises if i do a wrong pattern on purpose, but it doesn't boot up system. It's spinning the lineage logo from left to right then back to lock screen.

I can go to recovery. Is it bricked again? Or there's a quick "do this X Y Z thing" and it will boot fine again?

thank you and sorry to disturb so much (wrote about the BT issue if you remember)

hvala!

Gabrio

WOW, i had to patch the previous build and phone worked, so guess something's breaking my encryption thing. At least it's back. in case it help others
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] SpinStudios:
Quick question : Does this rom have adaptive battery like on modern samsungs where it learns how you use the phone for a certain time then battery life gets better? Cause i can't find a similar option in the settings but i could when my modern samsung still had android 13. So is it just a feature the manufacturer implements or is it os based?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] hippo66:
That's right - this was my next step - I unselected the Zip signature verification in the Install option of the separatly downloaded file and voilà - success. Sorry for my delay!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] netra3441:
Installing the update from June 16 via TWRP (I still use the elder 3.7.0_9-0) and with dirty flash works fine, ZIP signature verification is off - but I never had used that anyway.

I have LOS20 running on my testing Samsung Galaxy S7, and I prepare to install LOS20 or maybe elder version on my daily driver S7 too in the next days, if there will not be an update for LOS21, what I actually still use on the daily driver .
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Alucard_75:
Hello Mr Meler, Google blacklisted LineageOS (Play Integrity), can you do anything about the blacklisting ?

If you can't do anything about it, it's not too bad, some apps don't work, but you can still make calls. :)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Mitsch79:
Same here. The Updater downloads the file and the verification fails. This usually happens when the zip-file is corrupted. Which can happen either when downloading it to the phone or when uploading it to the server. Since there are several users with this verification failure i'd think the file on the server is already corrupted. At this stage it has nothing to do with the zip signature verification.

I'm on may update at the moment and will wait for the next update, that will probably be ok by then.

I would not recommend trying to flash a corrupted zip file.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] SpinStudios:
The file isnt corrupted i downloaded it on the phone with the 3 dots next to download button and installed it via twrp thats it!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] ScanX:
18.1, 19.1 and 20 builds with June update will have to be manually flashed instead of being flashed thru ota,

Thats just a one time thing and next months build will be flashable thru ota again.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] SpinStudios:
Is it possible that you could implement screen resolution options? Trying to save as much battery on this phone.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Soni03:
Hi, I do have a strange behavior (bug ?) on my Lineage OS 20.0 that is working fine otherwise : after a certain time (random time) I have a black screen + timeclock that appear as a screensaver. Impossible to do something after that, except an hard reboot. Someone have the similar behavior ?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] easylivin:
Yes, but very seldom. Last time I experienced this it was very likely caused by a crashing app.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] aki42:
Did you place the smartphone somewhere near a magnetic field? IIRC I saw this type of display, when I put the smartphone on the back of a tablet having a magnetic back cover.

Try to place the smartphone near a magnetic field again - e. g. the magnetic seal of a refrigerator (though I don't know if the seal's field is strong enough).
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] haumich_blau:
Yep, as mentioned: magnetic field. If a weak magnet touches a specific edge of the phone, it thinks it is in a foldable case, with the small clock for the window of the case.

The foldable case of my ebook triggers it when they are in the same bag. Then I have to drag the magnet of the case over the phone edges to unlock it again
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] steve8x8:
And once you've triggered this behaviour you may disable it (but not earlier - which is something I consider a design flaw) - check for "smart cover" in the settings.

Samsung's original firmware was built for their book covers with a window in the top one-third (and a small magnet), and this feature made it into custom ROMs as well
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] bibold89:
Hey there,

third time installing these files:

lineage-20.0-20240616-UNOFFICIAL-herolte.zip

NikGapps-full-arm64-13-20240420-signed.zip

After the S7 runs out of battery and shuts down, I am not able to unlock it. It starts, shows me the display for entering the pin for about 1 sec and then just turns dark. That's it.

How can I fix this?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] netra3441:
Well... als long as you do not exactly describe, HOW you had done installation, as long no one can tell you more.

So please tell us exactly, step-by-step, what you have done.

Most of of time there are misunderstandings by not reading the HowTos exactly, some use very old TWRP (actual one is twrp-3.7.0_9-1-herolte) or do mistakes inside of TWRP, and others.

Therefore it is essential to know, how you did it...
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] bibold89:
I was using lineage-20.0-20230718-UNOFFICIAL-herolte before this one.

I did a clean flash with TWRP version 3.7.0_9-0-herolte.

- Backup of my files via USB

- Boot into recovery

- Factory reset (dalvik / system/ cache)

- Install lineage-20.0-20240616-UNOFFICIAL-herolte.zip

- Install NikGapps-full-arm64-13-20240420-signed.zip

- Reboot

So a fresh start but this time I used the full NikGapps package. Yesterday I had the same problem but let it charge over night and this morning the display worked when my alarm went off.

Did I forget a step?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] netra3441:
@bibold89

Your TWRP is elder. Take the newest TWRP version, as far as I know the new LOS-Versions need the newest TWRP.

For Europe and the Samsung Galaxy S7 you find it here:

Download TWRP for herolte

Download TWRP Open Recovery for herolte

eu.dl.twrp.me

For America here:

Download TWRP for herolte

Download TWRP Open Recovery for herolte

dl.twrp.me

I used the newest TWRP on my Galaxy S7 and it works fine.

Better not to use the full *Gapps, use the smallest version, at NikGapps this is Core, I guess. Never forget, that Galaxy S7 is more than eight years old, so do not burden it too much.

Hint: Myself I do not use any *Gapps, because Google stuff is really not neccessary. All *Gapps make the S7 slower...

Another Hint: try LOS21 instead of the 20, because this runs fine with Galaxy S7...

Informations about Ivan Melers LOS21 you find here:

LineageOS 21.0 (Android 14) [Signature Spoofing][OTA updates] for S7 Exynos

LineageOS 21.0 for herolte /* * Your warranty is now void. * * I am not responsible for bricked devices, dead SD cards, * thermonuclear war, or you getting fired because the alarm app failed. Please * do some research if you have any concerns...

xdaforums.com

Please be aware that when installing recovery or rom, always before have charged your S7 full. Low battery and then system operations is not such a good idea.

Beside that it looks you did well.

Good luck. Hope these infos help a little.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] netra3441:
Hi guys,

does anyone here use LOS 20 from Ivan and has installed Instagram app?

If so, does your S7 gets hot, means really hot, when you watch videos in Instagram?

ADDENDUM on July 29, 2024:

Some of you may have also noticed, that the Instagram app on our S7 overheats, the Samsung Galaxy S7 here then gets so hot that you can no longer hold it in your hand.

At first I thought that this was due to LOS 21 QPR2 (what I am using) and that it was the same with YouTube, but that's not true. LOS is not the reason for that.

Because iPhones also have the problem with Instagram, the manufacturer Apple has already made public allegations to the company Meta, which publishes Instagram, that the Instagram app is also making iPhones hot recently - you can google this, there are a lot of informations about.

But I found also a solution on the Internet how you can continue to use Instagram to read and watch without using the app itsself, and the smartphone (here the S7) hardly gets warm:

You install the Brave browser, which is very data protection conscious and stops advertising, work through the Brave browser settings, and then use instagram.com in Brave, and you get the same as with the app, just without the smartphone running hot.

Maybe this will help someone.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] crusader290:
Awesome work! Makes my S7 look and feel brand new.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] blazethelight:
@carli_nero:

Maybe if Lineage OS 20 Support Batterysaver Mode?

First impressions of the Rom is great for me.

All working except (maybe only because Android 13 too new?):

- Paypal App, Sparkassen Banking Apps, Intune App (require device encryption)

- Clock - Alarm Labels to small if edited label names

Whishlist:

- Root access

- Device Encryption

- Working Banking Apps, Paypal and Intune Apps

- Change display resolution (can't find into settings and I I mean, I have only HD ready resolution 720x1280 active)

- DPI Settings

- Hardware keys lights (isn't a device tree bug or this dev)

- Device very hot if loading

- Batterysaver option

- Screensaver functionality (is there but not working)

Just did a clean installation, no GApps. I encounterd 2 issues. First when I swipe up there is no app drawer, just an option to search for apps which also doesn't work and second, I can select gesture navigation but only the swipe up function works. When I swipe to go back nothing happens.

Did another install and again same issues. The md5sum checked out fine. Any ideas?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] MNNR:
Go to settings>Wallpaper & Style

Scroll down to App Grid and change size to 5x5 or lower, That should fix it.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chomsky55:
Indeed it did..hopefully this gets fixed soon but so far great work by the developer.

What about the gesture navigation, is there a fix for that?

This will surely be corrected in a following rom. Patience. ;)

Great, everything's working so far, its just when unlocking the device it crashes and goes back to the lockscreen on first attempt and screen recording is broken while recording a video longer than 10 secs, the system ui crashes. everything else is working perfectly well.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] przvl:
Android 13/LOS 20.0 looks and feels great on Galaxy S7!

However, it worked well for 2 days for me, but now I'm stuck with most apps constantly crashing after a couple of seconds (seems to be related to apps using the network connection, system apps like camera, gallery etc. work fine). I don't get any crash reports or error messages. Whenever I open an app it crashes back to 'desktop' (what's that thing called in Android? :D)

I'm running latest TWRP (3.6.2.), did a clean flash and use NikGapps Basic with latest Magisk (25.2).

Any idea on how to solve this issue? In this state the phone is almost useless (except for calls and sms - but who still uses those). Help very much appreciated.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] MNNR:
Webview related apps started crashing for me sometime after installing the initial build,.

What I did is, Wipe system, Install latest build , NikGapps-Core, And Magisk.

I suggest you give it a try and see if that fixes the problem, Not sure if that's what fixed it for me though.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] przvl:
Alright thanks! A quick wipe of system+dalvik-cache and reflash of LOS+NikGapps-Core+Magisk did the thing. Although it makes me wonder how long It'll work this time and what caused the crashs to begin with.

The only problem that does not allow you to use this firmware, when the interlocutor hears himself, he has an echo. This problem is probably on all custom firmware and it can not be solved in any way. It is extremely inconvenient to use because of it. If there is a way to fix this, please let me know.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] kjoetom:
I'm sorry to have to disagree with you, but the echo problem is definitely not solved for everyone. LineageOS 16 is the highest version under which the echo does not occur for me. I have just tested this again with the latest version of Ivan.

Perhaps the only reason you read less about it in the forums is because those people who have an affected S7 have resigned themselves to the fact that there will be no newer LineageOS versions usable in their cases (at least not for making calls and keeping friends at the same time). ;-)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] meesam3379:

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] grindim:
Recently I tried LineageOS 19.1, there was an echo, so I did not try again. I've been using LineageOS 20.0 for several days now, everything works very well, the battery keeps well. There are no serious shortcomings. The browser could not access the memory when downloading the file, and did not figure out how to fix it, put Chrome, there is no such problem. Unfortunately, the interlocutors constantly complain about the echo, so I'm waiting for the problem to be fixed, I don't want to return to the original firmware, but I don't see any other alternative.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Ivan_Meler:
New builds are out, here is a brief changelog

- Added button backlight control

- Unpinned deprecated updatable media apex jar from ram

- Allowed system to override some bluetooth props

- Performance and stability improvements

- Synced with LineageOS source (Almost all of lineageos features should be there and work now)

Almost all of the lineageos features have been ported to Android 13 now and are working, there still might be a missing few compared to android 12.1 like toggle for software buttons which is work in progress at the moment.

There are also some device side changes that should improve performance stability and battery life

But I will be better in the next time, I hope, and then I'll gonna get the bull at its horns... :cowboy:
