So I went an enabled "Jumbo Frames" on my 4200 and FW just frozed. When I tried to detect it with Raidar, it finds the device but when I click on "setup" I get an error "Class not Registered"

Does your router or switch support jumbo frames?
Perhaps try a direct connect from the ultra to a PC, and see if you can run frontview that way.
If your ultra is set up to use DHCP, what you do here is
(a) connect an ethernet cable directly between the NAS and the PC (nothing in between)
(b) set up the PC connection temporarily to use
IP address 192.168.168.100
subnet mask 255.255.255.0
gateway 192.168.168.1
Then open a browser and enter https://192.168.168.168/admin
If it works, then turn off jumbo frames.
