How to decrypt .LUA files?

[Bahamuuut]

I managed to decompile the apk using AdvancedApkTool by BDFreak. Some guy in other forum told me that I won't find anything in its lib folder. He gave me a hint that it uses lua and told me that i should decompile/decrypt it. So how do I decrpyt lua files? The one i found in the internet was decrypting .luac files not the lua files itself. I opened some of its lua files using Sublime Text 2 and it contains a somewhat memory addresses. Any help out here?

What do you mean? Lua files can be opened by any Text editor its just lua runnable text. Can you send a screenshot or the text itself?

@Skullboyq here take a look at this: http://imgur.com/hQ6VCxD

By the way, this game is called Pocket Three Kingdoms (Pocket Summoners). It is a server-sided apk which i am trying to create a modded apk. Any suggestions?

Here was the post I posted on the other forum that i was talking about:

You can look at circleous comment at my post. He wasn't replying to my comments so I posted a help in this forum.

Hmmm i don't understand much of that i think we'd need @Enyby he is the lead coder here so he can help you more than me but i will do my best too and share my results

Really? Thanks @Skullboyq ! Finally, a decent tutorial for apk modding... but question, is it modifiable? Apps that are server-sided? 

[Skullboyq]

Most Serversided Apps are modifiable but some are 100% Serversided which are impossible to mod i think

You need find point of load these lua files and look what used to decompile it.

It can be anything custom way.

@Enyby hmmmm like what?

Sorry guys i really tried to google things...

[Enyby]

I think this point located in .so file. It can be some xor for each byte of file as example. Find this plsce can be hard and complicated.

[Bahamuuut]

@Enyby in its lib>armeabi it contains:
-libc++_shared.so

-libcocos2dlua.so

-libmp3lame.so

 

I put all of them in IDA PRO 6.8 but i found no functions like health skills etc. The guy from alphagamers.net said i wouldn't get anything from these files.

[Enyby]

This code located in someone sub_xxx function. It hard to find.

 

Guy say this about lua file, not about all info. In this files no lua file, but they contains code for work with lua.

[Bahamuuut]

@Enyby yup there's plenty of sub_xxx function there. I tried Shift+F12 but didn't get any results. Also tried to find in the Functions Window. Maybe i need to do a live debugging?

[Enyby]

May be. But it complicated stuff. I can not help with it. You must do it yourself.

[Bahamuuut]

What programs do i need to use when live debugging?

[Enyby]

For example gdbserver + IDA. It is not only one choice. You can do it with gdb only. Or with some other tools.
