Okay, whilst crossing my fingers I checked Google's Android developer downloads and downloaded what appears to be a last-updated 07/17/2013 adt-bundle?this, oddly enough and albeit producing the same error outputs, worked. The phone also froze at the boot animation for quite awhile, remembering another having similar problems I scrolled up and tried the unlock/lock oem-bootloader... viol?! I'm now reinstalling and setting up the new phone!
After this experience I see why it's understood that it's nigh impossible to brick a Nexus device! I'm only partially an ***** when I'm impatient!
Nicely done! And thanks for sharing, as I'll have to take a look and see if I need to update something or link to these files as well.
