After instaling the Enigmah Final and you turn the XBOX back on for the first time it should boot to the original M$ dashboard. If you get a black screen then the most probable cause is that you haven't selected the right jumper for your bios version. Also there are 2 Final enigmah's 1 With PCB Error 1 without the PCB error. If you have selected the right jumper and followed the fitting diagrams for your specific Enigmah version then just recheck all your connections.

Hope this helps you.
