I want to unlock FPS of a game named laya's horizon. I have dumped it's protected il2cpp file and attached the results. What would you guys do next ? Edit application.targetframerate ? Some other parameters ? At what RVA will you use the hex editor.

Yes, you can hex patch get_targetFrameRate.
If the game is for pc, then you would also need disable vsync (set QualitySettings.VSyncCount to 0). But this game is a mobile game, right? Then you don't need to worry about vsync.

So yes, just editing application.targetframerate should work

Well, there are three references in dump file for that function. And only one has a rva value with it. It is, application target framerate set(int 32)().

I don't know hex editing or arm8 hex code editing. Do you have any idea how to actually edit the value.

There is that get method I mentioned in your dump, use it's rva:


There are many tutorials here like this one for hex patching
ll2Cpp Dump + Modding
But basically, first you need a hex code which you replace the original code with:

This should do: E0 7C 80 D2 C0 03 5F D6, code for int number 999.
You can make your own in armconverter.com by replacing the 999 with another number.

Then open libil2cpp.so in a hex editor, ctrl+g and paste the part after 0x of that rva: 194ae80 and enter.
You are now in the address of the rva. Then copy that hex code and press ctrl+b to replace original code.
Then save and build your apk with the edited libil2cpp.so

I took the hex value you gave and put it in the address. I then copied this file to my rooted android, in the game lib's folder and game crashes. Any idea why ? Should the game crash if i just replace lib ? Do i need to compile it ?

I suspected some corruption so I started the project again. This time the game didn't crash when I replaced the hex edited file. But the FPS didn't unlock either.
