[Windows Phone 8 Development and Hacking] bruce142:
[MENTION=3529492]GoodDayToDie[/MENTION] : Do you think the zmz could be intercepted and another program could be put into place? Like putting the WP8Diag in the place of another program of the same size and thus bypassing the interop-unlock requirement for writing to the registry? Just brainstorming here.

Did anyone notice the Samsung.M8X60SOC.SecureBootKey.dsm.xml in the location Samsung ATIV S\Phone\Windows\Packages\DsmFiles, maybe it's not just a blown fuse which causes the bootloader to be locked? It's refering to a cab with some sha1 hashes in it : Samsung.M8X60SOC.SecureBootKey.cat located at Samsung ATIV S\Phone\Windows\System32\CATROOT\{F750E6C3-38EE-11D1-85E5-00C04FC295EE}.
