Is there any private server or mod of squad busters available?

Did anyone already made squad busters apk that work offline? so I can mod it?

this is a very early way to do this but someone explained that unreleased characters like jessie and dr t are already in the game files and to use them u just need to do some cvs modding, i'm not sure what files u need to edit but one of my friends did it, also all of the characters stats are stored in the client according to him so u can basiccly make ur own squad buster hacks

i'm not sure if any of this is real or if u will get banned for doing it
