Cant Downgrade Firmware

So I am trying to downgrade my firmware so I can use the NFZ. On the site it shows that I need V01.00.100  So I downgraded my Mavic 2 with assistant to V01.00.0300 as that shows you can downgrade via NLD client. Then I try to Downgrade to the V01.00.0100 using NLD. It just hangs at 15% saying that its checking the Modules MD5 and never goes any further. Anyone else have this problem or know of a fix. I have submitted a support ticket.

Thanks
Craig
