I'm trying to extract models from this game, I've seen some floating around the internet so I know it's possible (although most tutorials are in chinese/don't work anymore).

The most recent tutorial I used was https://www.youtube.com/watch?v=Dp90rbVntb0&t=78s which has me using Nox and Ninjaripper.
But it only works with Nox versions 5 and below, which at most use Android API 19 and that's unfortunate because Love Live All Stars only runs on Android devices (and emulators) with at least Android API 21.

A previous tutorial I used was https://www.bilibili.com/read/cv3755709 ... icleDetail but unfortunately it is in chinese so I'm at the mercy of my browser's automatic translator~
This one has me using the APK and Asset Studio along with some Blender/Cinema 4D and MMD.
I remember using this a little while ago and had it working but I got stuck in the last couple of steps so I decided to put it off for a little but now that I'm back I can't find the right APK.
I used APK pure to get the file but when I load the folder into Asset Studio I get pretty much everything EXCEPT the mesh files.

If you've got the time and the knowledge, please help me out!

I recently started RE-ing this game. Only issue im having is finding where the code is getting loaded from since the libil2cpp.so seems to be mostly blank.. it must get loaded on the fly but i havent see any difference from my ram dumps made via game gaurdian.. i have a symbol map dump essentially but no code.. need that code to find the keys.

Edit: Seems libil2cpp has some really obfuscated snippet of code in it that appears to write bytes to mem. So im guessing its just really, conveniently packed/compressed/encrypted

Edit2: Finally figured it all out.. Got the assets dumped!

ARE YOU SERIOUS?? That's AMAZING news!!!

I'm sorry for the late reply but could you please share the files with me? I'd also really love it if you helped me through the process you used to find the dump the files (though I understand if you don't want to go through the trouble) so that whenever the game updates with new assets, I'll be able to acquire those too! Please let me know if you're willing to help me out!

I was able to get the game files and extract them in 10mins using APK tool.

Click on assets.. And load them with Unity.


Extracted/Converted

I appreciate your help! But unfortunately this method doesn't get past the game's encryption and only delivers assets such as textures, shaders, etc. I'm trying to acquire the 3D models used in-game. The only meshes obtained through this method are the default Unity objects, such as planes, cubes, and cylinders. I arrived at this outcome before, using Asset Studio. Back then, the method worked and I was able to use see the meshes I wanted, however, it does not work anymore and I'm assuming it's because the files are now hidden behind a new encryption.

Still I'm thankful for your suggestion, I wasn't aware of your method until now!

This has models, textures, sounds, animation. Everything. What do you mean ?

If that is the case, then I must be doing the process incorrectly. I apologise for my assumption.
I downloaded Easy APK and opened the APK file and decompiled it and assumed that was what you meant. Unfortunately, my error does not lead to the proper game models.
