Halo 4 Terminal? Seems odd...

Remember that random terminal pic a few weeks ago? (Octuber 30th, 2012-ish) Well, I think I just solved it. http://i.imgur.com/1RJCV.png
And it gave me this error…
anyone interested to find out what this means?

I solved it. for me it unlocked raider shoulder pads.

Have you completed Halo 4 on Legendary and found all 7 terminals in game?

I’ve found all the terminals, I’m starting legendary this weekend.

Edit: sorry, Morpheus, I thought you were talking to me, not the OP

Oh, thanks for finding that! Can you at least put all the terminals or something, more info?

And what about mythic difficulty, people?
