VERY NOOB question, but if you have the Z2 do you need to unlock the HDD to bypass it?
Or can you just bypass it by doing the two wire ground and using the ISO image (never touching the HDD)?
Sinkoumn: please read the first post in this thread:

And no you don't need to unlock it, follow the directions in that thread.
