I think I will need your help regarding this now... I'm stuck at the situation where I will have to go back to the stock GB as somehow my copy of HC is bad and a restore/recovery is impossible (somehow a mismatched MD5), now I'm stuck the recovery as I am not sure if the GB would work on a HC HBoot.

What exact hboot do you have?

Procedure added.

So how would I upgrade to S-OFF Honeycomb, if one of the steps for HC->GB downgrade is to use the HTC unlock? Or is step 5 ("Relock the bootloader") undoing the HTC unlock?

Step 5 covers that.
