With the Android SDK it is possible to run the "adb shell" command to shell into an Android device plugged in via USB. I would like to know:
Is there another way to log into an Android device and gain root access to all its files and folders without having to install the Android SDK, for instance using Putty somehow once the device is connected via Wi-Fi to a router on a common network?
On Unix there is a program called "last" allowing you to see the most recent logins and the associated times. Is there a similar utility that can be run on Android once root access is gained that would allow you to view the most recent times when the device was used or unlocked?
