10.7: Restore Apple Hardware Test boot mode
Authored by: AKazak on Feb 13, '12 04:26:08AM

I've got MacBook Pro (15-inch, Late 2011) with Apple Hardware Test originally accessed by holding D at startup.
However after restoring Mac OS X Lion by the Internet using Lion Recovery D-key stopped working. I've followed the tip and copied .diagnostics folder:

ls -al /Volumes/Macintosh\ HD/System/Library/CoreServices/.diagnostics/
total 48
drwxr-xr-x 3 root wheel 102 Feb 13 16:06 .
drwxr-xr-x 125 root wheel 4250 Feb 13 16:06 ..
-rwxr-xr-x 1 root wheel 22590 Feb 13 16:06 diags.efi

and

ls -al /Volumes/Recovery\ HD/System/Library/CoreServices/.diagnostics/
total 48
drwxr-xr-x 3 User staff 102 Jun 27 2011 .
drwxr-xr-x 4 User staff 136 Jun 27 2011 ..
-rwxr-xr-x 1 User staff 22590 Jun 27 2011 diags.efi

However the D-key still doesn't call AHT as expected.
What else should I try?
