There appears to possibly be a new firmware/hardware revision for the LiteOn drive that was originally posted on these German forums. It is being discussed on our forums
here
So far, it is just speculation at this point. It appears the user is claiming the key's are coming back all 00's. We are unsure if it is user error, or a new protection. Any users with this revision please email iriez at xbins dot org with any information. If it truely is new protection, we will need to get our hands on it! Donors will be taken care of!
