I followed these instructions diligently. After re-assembly and booting the system, I am experiencing intermittent video, mostly black screen with flashing grey and brief appearance of the Apple logo. While I cannot say for sure, the boot process makes it as far as the filevault login screen. I have tried multiple boot drives with no change. It seems like the system has been bricked.
Has anyone seen this before? It does not matter if I tap into the HDMI or mini-display port.
Thanks in advance.
