Just a quick heads up... If the device you use has a boot loader and requires the use of fastboot.exe from the android-sdk/platform-tools/ folder to make a connection to unlock your device or flash recovery then read this...
I just found out yesterday after attempting to flash a new recovery to my device that somehow my fastboot.exe had gone missing.. Come to find out when you update your android-sdk it removes fastboot.exe from your platform-tools folder.
Anyways... Here is a link to fastboot.exe in case you come to find out your missing this too...
Download : fastboot.exe
