[Q] What is "fastboot"? (Solved)

---

Whenever I SBF my phone, I always see "Fastboot" as the first option... I've always been curious as to what it does. Can someone explain to me what it's used for? The only information I've found on it is that you can use the command 'fastboot oem unlock' in ADB. People have said it unlocks the phone/bootloader (not on the droid X2 obviously).

I'd just like someone to clarify what it actually does.

Fastboot is protocol used to update the flash filesystem in Android devices from a host over USB. It allows flashing of unsigned partition images. from Android Wiki

I'm guessing this is something that wouldn't really be using on Moto devices, considering the locked bootloader.
And the command "fastboot oem unlock", is that just for unlocking a bootloader or will it actually unlock phones that have otherwised when 'locked' for some reason?

No clue on that but im guessing your right about not being able to use it unless the boot gets unlocked and that's never gonna happen on purpose

It has uses other than unlocking the boot loader. In fact, I would guess most anything you can flash in CWR can be flashed using fastboot. It's just a matter of knowing how to use it. You use it from a command prompt in Windows. If you happen to have ADB installed, you have fastboot too. It comes with ADB.

I used fastboot to change the moto logo on my x2 so at least its not completely useless.

Pretty sure the bionic users have fast boot files available via team black hat.
I think they use them to return to stock image or something to that effect lol
