Title just has it...

What are fastboot files for? everyone keep saying it's a good thing and etc... but I don't really know what's the biga deal

It's the phone os in a file.

Different from the old .sbf, in that it doesn't destroy user settings, accounts, sms etc.

To add to that it is for recovering from a soft brick. So it is kind of a big deal. It may also helps devs not be so gun shy.

If u install a costum rom, fastboot files let you back to moto stock rom

Thanks guys!

So is there any fastboot for the GSM version yet? If not, is there any way to extract it?

Spend about 2minutes and look at developer threads, you can find them

Bit confused here; the boot loader is locked so you can't change the kernel (os). Is the fastboot stuff everything but the kernel; just the jvm; not the jvm but the basic files that are executed by the jvm; the ...???

The kernel can be flashed by these files, since it's encrypted with the correct password.

We'd need that password to bypass the hardlock, but unfortunately noone will ever want to experiment with that since it may blow e-fuses, rendering his or her phone forever dead.

By the little I know of cryptography, the fastboot only has half the key.

Previously no phone actually used an e-fuse (it was proven on earlier moto phones that e-fuse was not enabled). Does the razr actually use an e-fuse ?
