Even if i analyze the file the options still remain the same as i have shown on screenshot, just that they are not greyed out anymore. Pressing f5 or shift f5 does not show me the pseudocode.

Maybe you don't have a decompiler available. Try installing snowman

I've already tried it and downloaded it.
But I couldn't open the libil2cpp.so file through idapro.
I'm sorry for my poor English skills.

What do you mean?
Also, since it is off-topic, you should post on MODDING QUESTIONS & DISCUSSIONS

I am not sure what does the code do after adding the header

 

[Tonikun]

Its always in the same place? I mean only in jsb-adapter, jsb-builtin.js or main.js?
