Something great is coming 😉

If you are asking about this
This is a solution for the owasp challenge UnCrackable-Level2
In this tutorial you will learn how to analyze full the app and understand its behavior, to bypass root detection by Frida and manually by patching the app, find the activation code which will be in the native code and this will open your eyes on how the integration between java codes and native codes is also what is JNI at the and finally how to patch disassembly by radare2 to bypass the checks of the secret code and more !

I know that there are a lot of people solved that change but I worked on it in a different way with various methods to solve problems
