Ok, i fixed the problem myself.
Even with no Nethunter App visible on phone or within the Apps Section, it seems that there are some artifacts on the device.
Since i had no idea about the internal package name, i used a adb logcat session.
Whilte logcat was running, i tried to install the latest.apk
Code:
adb install latest.apk
On the logcat, you will find a message like this:
Code:
PackageManager: Package com.offsec.nethunter signatures do not match the previously installed version; ignoring!
So i could use those information to call adb uninstall
Code:
adb uninstall com.offsec.nethunter
It succeed.
So i could call
Code:
adb install latest.apk
again, which also succeed.
