Help finding LZO key of a client

Hello, elitepvpers's community!
The server I'm playing on has a very bugged switchbot and the owner doesn't want to change it, so I tried to inject TyKode's switchbot into the client, but it won't let me. So I thought they have some protection inside root, but EterNexus won't let me decrypt the files. ( .eix / .epk )

From what I've searched it means they have changed LZO key. I watched some tutorials, but I can't figure out what is the key.

I opened the process with HxD and searched for " AVCEterPack " like in the tutorial, but this is the output:

HxD output -> It means that it's crypted or something? Can you help me find and teach me how to do it? Or give me links to some resources from where I can learn? I did search, but haven't found anything.

It passed a week since I first started and couldn't figure it out...

I'll also upload the client and the patcher if it comes in handy for you :)

Thank you!

Try this.
Add me Skype ( rikyu.elitepvpers ) if you have Problems.

It doesn't seem to work, it returns the key next to the selected text in the picture of my first post.
It returns this:
That for the client, if I use for the patcher I obtain this:
I've changed the LZO of EterNexus to those, but it doesn't decrypt any file from the pack folder

I've added you on skype :)
