[Android General] ShaDisNX255:
You got me there, that I didn't do. But now checking with MiXplorer, the folders (app and priv-app) have ALL permissions (Owner, Group and Others set to Read, Write and Exec)

Ok so here is what I got so far:

Copying the /framework folder makes it so that it doesn't boot

Recovered from backup and only copied over app and priv-app folder.

It boots

However, some apps (like Samsung Keyboard) keep crashing over and over, reading the logs it says something like this:

From what I understand is that it is not finding this lib file (the .so file), but upon looking through the apk with winrar, I see the lib folder intact and with all the .so files in there

Even copying the lib folder directly in the SamsungIMEv3.0_MASS folder does nothing

There are a couple of apps crashing because of this exact same problem like FOTA agent (looking for lib files and not finding anything)

The FC pop ups are really annoying lol

But yeah, that is what I got so far. I even deleted the com.sec.android.inputmethod folder from data/data and no luck either
