ADB, the Android Debugging Bridge. If you want it to connect to Android > 4.2.2, or in other words, anything from this century, you can’t use anything less than ADB 1.0.31. By default, mobisec comes with 1.0.29, so even if the device is rooted, the device appears to be offline.

To upgrade adb: First download android-sdk-linux, from here: https://developer.android.com/studio/index.html near the bottom where is says “Just the tools” Once you download, unzip and all that, cd into android-sdk-linux and run: tools/android update sdk –no-ui

To get 32-bit adb: http://askubuntu.com/questions/710426/android-sdk-on-ubuntu-32bit, as of this writing, it resulted in version 1.0.32 of adb.

Installing Drozer: (Drozer site) Need the .apk for the device, and the platform. Both are available at the Drozer page. Start up the agent on the device, and it should be running on tcp:31415, then do the port forwarding in the platform. If the device and the platform connect, all good, and fire away!

If we get:
mobisec@mobisec:~$ adb devices
List of devices attached

Then stop and start the server with sudo.
