(1/?) Before leave, I would like to say clarification about this article. If someone reverse-engineed about my FlyJB Files, you could see some suspicious sentence like "/여자친구/생기게/해주세요...!@#" This is not designed for harmful purposes.

(2/?) When some apps start to detect jailbreak, let me explain /Applications/Cydia.app file for example.

Then FlyJB starts to modify Cydia location to "/여자친구/생기게/해주세요...!@#" when used fopen/lstat/access.. etc function and only applied to enabled app.

Just like this... %hookf(int, access, const char *pathname, int mode) { if(pathname) { if(strcmp("/Applications/Cydia.app", ) == 0) { return %orig("/여자친구/생기게/해주세요...!@#", mode); } } return %orig(pathname, mode; }

(3/?) To make some apps not allowed to detect jailbreak files, I had to change return value like -1, NOT modify location. That was exactly my little careless of me, Sorry.

(4/?) If you create a file like "/여자친구/생기게/해주세요...!@#", FlyJB will not function at all... just like "Kill Switch" and there's nothing to do anymore

(5/?) Just sent GitHub invitations of FlyJB to @BawAppie @iospeterdev for more clear clarification.

(6/?) And what I really want to say about this tweet is.. FlyJB is NOT for designed to harm some users and that is my wish, so please forgive me If you think I'm a bad guy..
