I was using Titanium Backup previously. It was working fine when I rooted my device before a month. But Because of some problem in my phone I again rooted my device, and now when I install this app, I'm getting error 504.
I tried so many things: I tried with different internet connection with high speed. I cleared Google play cache/ services cache clear data etc. I reset app preferences. I downloaded apk from apkmiror. I tried with signed testing APK. I tried with the edit common files like change app name.
