After the new update we couldn't fuse some epics so i wanted to try that with an older version.

before updating i took backup with titanium so i have the older version but when i'm trying to log in the app forces me to download the new version.

 

i tried to modify some files but with no luck, so i would like to know if it's possible or maybe i can get a tip on where to  look at.

 

thanks in advance.
