A Nokia Lumia 625 failed to reload the system with the Windows Phone Recovery Tool 1.0.4 (released earlier in 2015 I think). The 625 had a Nokia screen initially but wouldn't respond to anything, or turn on, or recover using any of the Microsoft or Nokia tools. Completely bricked.
The good news is that can now be recovered. The latest version of the Windows Phone Recovery Software is 2.1.1. Spotted the phone right away, warned to charge the battery above 25%, then reloaded the system. Only took 10-15 mins, and the phone is back! De-bricked. Un-bricked. Whatever the word is.
