I'm using the Fortunecity app (https://play.google.com/store/apps/details?id=com.fourdesire.fortunecity)

However when I try to use Lucky patcher to create modified APK file, an error screen shows:

"Crack mode N1 - Failed"

"Crack mode N2 - Failed"

"Crack mode N3 - Failed"

"Crack mode N4 - Failed"

Is there any ways to solve this?
