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)

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".
