Adb and Fastboot commands

In this list, you will find some regurarly used ADB and Fastboot commands, with some explanation on them, what do they do.

Preparing:

In order to use the commands below, you’ll need the Minimal ADB and Fastboot program installed.
You can download it from HERE.

When installing the program choose such a folder, that you can copy a few GB sized files into it.
You should copy the files you are want to flash into this folder, because it’s much easier to type only the name, instead of the full path of the files.
After flashing these files can be removed from the folder.

After the installer has finised, you’ll find a shortcut in your Desktop, but you can use the MAF32.exe in the install-folder to fire up the command line.
