treequell I thought the same and wanted to check the option, but when I go to recovery mode i actually get the rescue mode (the dead Android robot). Is this a bug or am I missing something?
Anyway, if this works it would be the best way, because not only does it take less time and works from the power off state, but the process is also more secure in case somebody takes your device by force. Instead of an unlocked phone they just get a phone in it's extra secure pre first unlock state. It's also easier to operate blindly in your pocket because you use the hardware buttons and could memorize the order of button presses.
