XG Firewall Home Edition on XG 135 Rev. 3

Question

Hello 
 I'm trying to flash the XG 135 Rev. 3 with XG Home. When trying to flash it with an USB it returns the error of "Detected Sophos physical device". I've read that you can do away with this by removing some partitions with GParted. However GParted doesn't seem to boot. Other Live-USBs with a GUI don't seem to boot as well E.G.: SystemRescue. 
 Does anyone have experience with this?

Alright, I did manage to do this. 
 First connect a screen and a keyboard to the firewall, this does not work over the console cable. Also connect an USB DVD drive. 
 Burn the GParted ISO to a DVD via Rufus and boot it. Once loaded choose other boot options and pick the load into RAM option. Typ "forcevideo" in the cmd to launch the graphical interface. There you have to option to remove the current partition, do so. Make a new partition, I chose FAT32 and press Apply. Remove the GParted DVD and insert the Sophos Home DVD and reboot. 
 This worked for me, hopefully it will work for you too. I hope we can ditch the DVD drive in the future. 
 I did notice that the upper 4 ports (1-4) are not working. I had to use port 5 for LAN and 6 for WAN.
