Ok, this is very bizarre. I am trying to load this OS on my son's 8330, using the same laptop that I upgraded the other one a few hours ago, and his device doesn't detect the new OS. At all.
Vendor.xml has been deleted. I don't get it. His MEID starts with the same first 8 numbers as the one I just updated.
No longer a BES Admin, but it was fun while it lasted!
