[Q] Extract Galaxy S4 App and Priv-app folders

Can anyone extract Galaxy S4 Android 5.0.1 App and Priv-app folders?
I'm sure someone can extract the folders. But will they? I doubt it, unless there's a good reason for it. So what do you need the folders for?
Or flash a stock rom, root it, access the system folder and copy the app and priv-app folders onto the sdcard.
If it is possible

[Q] Why this edited and signed ap doesn't want to install?

I have changed several png files (icons) in this app, deleted META-INF folder and signed using ZipSigner.
When I try to install this apk I get "Application doesn't install" (Android 2.2.2).
I try to copy apk to data/app folder, but I get "App isn't installed".
I try also one_click_signer.
Original apk worked well.

[Q] How to install cereberus.apk as a system file?

Hi
I have a question because I don't know how to install cereberus.apk as a system file.
I have single .apk file but in system\app I have some folders with apk files inside.
Do I need to make folder for my apk file or only copy this and change permissions (644)?
And which is the best place for this apk:
*system\app
or
*data\app?
Thanks a lot
If you are rooted you can use titanium backup to change it from a normal app to a system app.

Alternatively you can drop the apk into system/priv-app, fix its permissions and then reboot.

[LGH870][Oreo] How to integrate apps update in rom.

After update from nougat to oreo, I've have problem with integration updated apps in to /system.
I do it like this:
1. copy apk file from data/apk to sd card
2. rename copied apk file to name of /system apk
3. extract lib folder from apk
4. copy newer file to proper folder in /system/app or /system/priv-app and replace file in it
5. Copy lib files extracted form apk to right folder /system/lib or /system/lib64
6. Uninstall update from /data/app
7. reboot + dalvik-cache wipe
In nougat it was working, but in oreo, app after integration, breaks. It cannot be open, and app name changes to random words (ex. google docs name changes to "write com.android").
To repair integrated apps I have to perform a full /data/ wipe.
Is it a some kind of protection? How to do it properly?
TitaniumBackup and Link2SD cannot integrate updates to rom properly without errors since Lolipop.
So no one knows?
or just nobody wants to write?
