LineageOS 19.1 (Android 12L) [Signature Spoofing][OTA updates] for S7 Exynos

[spec_au]

After installing this ROM, does the ROM get updates automatically (like regular android os) including security updates - or has does this need to be manually done each time there's a release provided here ?

Also, if manual, is there a process without wiping the installed apps & data ?

Hi, it is manual.

Just dirty flash over the current ROM without wiping anything.

Is there a way for you to provied us with option to enable AC3 and EAC3 audio codecs?

From what I have read to use those codecs you need a license from Dolby so they were disabled by default in LineageOS. They were implemented in OneUI Samsung roms I used before.

Hi man, I'm also new at this and after a quick google search to see how I can dirty flash this December update, I found that people generally agree to do a Dalvik and Cache wipe in TWRP and than install the new ROM over it.

I did that and got a nice case of the good ol' boot loop, which in turn dosed me with a nice amount of the good ol' cortisol. After trying to make sense out of it, I managed to figure out that you also need to flash gapps over it and magisk if you use it.

Now everything is up to date and working as it should. No data on the phone was deleted and all my settings remained the same.

TLDR - To update ROM
1. Wipe Dalvik, Cache
2. Flash ROM, gapps (bitgapps_arm64) & magisk if you use it.

This worked for me flawlessly. Hope that helps.

Where is cards and passes to deactivate GooglePay? and where the advanced bootmenü to reboot directly to recovery? Maybe next Image?
I found on https://forum.xda-developers.com/t/...t-w-wallet-controls-on-android-11-12.4339025/ a interesting solution for a power menu with a button to boot direct into recovery.!!!!!!!!!!!!!!!

I can confirm #17:
Upgrade from latest 18.1 with BiTGapps worked well:
Flashed latest TWRP - 3.6.0_9
Wiped system, cache, Dalvik, but not data
Installed lineageos 19, BiTGapps, Magisk 23, flawless reboot into system
SaftyNet test success

Great job, Ivan!

Hey Ivan, thank you for this update. I found the following issues (compared those with another Android 12 device):

1) the date on the lock screen should be a bit more up near the top of the screen (with no notifications shown)
2) the clock color is accent color and should probably be white as it looks out of place
3) in the app drawer, the app search bar is partly on top of the first row of apps
4) after using the app search bar, filtered apps won't come back after removing the search term

Not sure if you can do anything about it, those are probably all LOS related.

Edit:
5) Touch gestures are sometimes difficult to trigger, e.g. unlocking the phone, swiping notifications, etc.

After trying to make sense out of it, I managed to figure out that you also need to flash gapps over it. So I wiped it again, this time I also selected the system, because I felt that maybe it could help.

Now everything is up to date and working as it should. No data on the phone was deleted and all my settings remained the same.

TLDR - To update ROM
1. Wipe Dalvik, Cache and System
2. Flash ROM & gapps (i use the recommended bitgapps_arm64)

This worked for me flawlessly. Hope that helps.

thanks for responding.

When selecting "system" in TWRP to wipe, wouldn't it remove the installed apps as well ?

That's the "data" partition. As long as you don't wipe it your apps wouldn't be wiped.

thanks.

so the only shortcut not available is the full download of the new release (as in, there's no 'patch upgrade' available with only changed files... )

Huh, really weird. I've actually noticed my playstore is not connecting to the internet. I can search apps, but when trying to download, it just say pending and in the playstore app manager it says your offline check your connection.

I've tried clearing playstore data/cache, uninstalling and re-flashing the rom, but nothing seems to work. Anybody has any ideas?

@spec_au that is correct, there are no automatic updates. You have to download the rom and flash it again.

Happened to me too. Someone said a reboot fixes that so I tried rebooting but I still had the issue. Then a day later it just worked (after another reboot). I don't know what causes it, but you can try a few reboots and be hopeful.

touch and hold to move a shortcut doesn't work

Hi,
could you please clarify GAPS flashing.

"nstall gapps right after installing the rom itself don't try to boot to system before that if you want to use gapps (Or wipe data before installing them)"
In the bitGAPS docs you can find:
"Standard Installation:
Installing BiTGApps from recovery. No feature enabled in config. But config is still there in internal storage.
Usage:
Install ROM
Reboot to recovery
Install BiTGApps/Addon Package"
and
"Avoid installing BiTGApps just after flashing system image. Instead reboot to recovery or reboot to system then install BiTGApps packages."

What is the correct scenario?
Flash GAPS right after ROM or
Flash ROM than reboot to recovery than flash GAPS.

Or do not take into head, both are ok?

Thanx.

I have moved from 18.1 to 19 and have found that...you need to ensure you have flashed latest TWRP - 3.6.0_9
dirty flash .. Wipe cache, Dalvik...
Install lineageos 19, BiTGapps or NikGapps (and any other add ons...I did Android Auto for NikGapps)
Install Magisk 23
Then reboot System....
As 'usual'... Ivan's ROMs...are pretty good...so...suggest...buy him a coffee!

Hi,
I was on FloydQ for a quite long time and now try to move to a12.
Very very nice,
but the echo issue makes me very sad.
When smbd calls me he hears his echo and it makes simple sound call nearly unusable for my opponent.
I tried PE12 - the same and the most sad, that this is "due to samsung sound driver which cannot be implemented here. Never."
Will try to move to Ivan's A11. Is there also echo issue due to "samsung sound driver"?

unfortunatly, if u want no echo, u need to use stock rom.

 

[krege]

have an issue with application list (slide up on main screen): search not works and after search list become empty. reboot helps. believe it's an lineage issue anyway.
connectivity issue: sometime mobile internet just gone. reboot helps.
