I need tutorial how to hack .apk with 2 days trial and without google play billing? Only uses activation cod buying on site... I don't know what to change exactly... I've been decompile with the apktool, but I still don't know I've been trying something
Galaxy Max HZ 8.1.apk https://github.com/tribalfs/GalaxyMaxHzPub/releases
