The file explorer app doesnt matter, forget
@SSEAD tutorial and do just what i say in post.
Every time you gonna play, check if data/data/com.survival.last/ lib folder is deleted (sometimes the game creates again the folder) and in
data/app/com.survival.last-xxxxxxx(x its random for anyone) and inside /lib/arm/ you will have a file name libanticheat.so, edit this file with properties and change permitions to :
Owner Read:yes Write:yes Execute:no
Group Read:yes Write:no Execute:no
Other Read:yes Write:no Execute:no
...all other options is off.
ps: what mod your using?
