To tell the truth... I can't remember.
I ended up buying a new programmer and also a faulty board, to get the chip from, assuming mine could be faulty.
I did the procedure and... nothing. Board still stuck on 5V. So I thought it have not worked. Because, according to what I found, it should be 19V even when on DFU mode. As I didn't have a newer Mac here to test this, I left alone.
Just past month I tried it, on a friend's MacBook Pro. And... even at 5V it was fund on his Mac. And I was able to get it back to life.
I bought a T48 programmer, but I don't remember exactly...
