Bootloader ?

[SirEagle]

Why can't Developers/Hackers figure out how to unlock a bootloader? If it's just some code or something in software can't it be done? Just curious as to why it's not crackable. Is the bootloader like the BIOS on a PC?

It's cryptographically signed using rather strong encryption techniques that, using brute force techniques and the fastest supercomputers available today, would take on the order of unthinkable years to guess the encryption key used.

I don't know which method Motorola uses, but assuming that they sign with a 256 bit AES random key, if you had a computer (or array of supercomputers) than could brute force guess 1 trillion random keys per second, it would take up to approximately 2 billion trillion trillion trillion trillion years to guess, on average (specifically, 1.8 times 10 to the 57th power years.) My math may actually be off a little bit, but not on the all of the trillions. It could be something to 10 to 56th or 58th.

So, it would be better for Motorola to give a method to unlock the bootloader.
