Hello,
this is a guide to unlock bootloader!

Prerequisites:
WPInternals: http://www.wpinternals.net/index.php/downloads (Download the latest one, 1.2)
WDRT: http://go.microsoft.com/fwlink/?LinkID=525569 (Needed for drivers)
HEX loaders: Link
FFU Image of your phone (You can download it from WDRT or from the site www.lumiafirmware.com)

SBL3 Engineering: Link
(SBL3 is supported only on: L520-620-625-810-820-822-920-925-1020)

Optional:
OSFMount: http://www.osforensics.com/tools/mount-disk-images.html

Procedure:

1) Download and install Windows Device Recovery Tool (WDRT)
2) Download Windows Phone Internals (WPInternals) and extract that in a folder (for example C:\WPInternals)
3) Create a folder named "Loader" into C:\WPInternals
4) Download HEX loaders and extract it in the folder previously created.
5) Download SBL3 engineering archive (Only if you device is in supported list)
6) Create a folder named "SBL3" into C:\WPInternals and extract the SBL3 Engineering archive.
7) Download FFU image of your phone from WDRT or from lumiafirmware.com

You should get this:

Now, connect your Windows device and start WPInternals:

Go to "Unlock bootloader" (on the left) and press ok, your phone will be rebooted into flash mode:

After entering flash mode you should do:
The first one you need to select an FFU image
(If you downloaded it from WDRT, go to C:\ProgramData\Microsoft\Packages\Products\RM-xxx\ and select the ffu image file. WARNING: ProgramData is an hidden folder!)
The second one, select the folder "C:\WPInternals\Loader"
The third one, if you device is supported, select your SBL3 Engineering image (In my case, Lumia 920) from the folder "C:\WPInternals\SBL3".
BEWARE that you can brick you phone if you flash the wrong image.

You should get this:

Now press continue and wait.

DONE! You have successfully unlocked your phone!

If you flashed the SBL3 image, you can access to Mass Storage Mode.

Is there a way to do this on other version of WM 10 than the ones supported by WP Internals?

Yes, it should work with that version.
Beware! I just tried unlocking the bootloader of 10586.242 on a Lumia 925 (RM-892) and got stuck at "Sending Loader". Next I'll go the recommended way:
  • Flash a Windows Phone 8.1 FFU
  • Run Windows Update until you have at least version 8.10.14219.341 of the OS
  • Unlock the bootloader using an Engineering SBL3 (only possible on compatible phones)
  • Run the Windows Insider tool and update to Windows 10 Mobile, possibly needs to run Windows Update a couple of times for the latest build
  • Enable Root Access directly on the phone
  • Bonus: Create a Cusom ROM

// update:
After several failed attempts (*aaaahahhhrhhrrgggg!!!!111111eleven*) I finaly got it:
Drivers from the Nokia Care Suite and the correct(tm) loader ftw. :)

    is it necessary for what?

    Editing BCD, creating custom roms, and so on (and someone expert can create custom rom based on android for example!)
