Hi guys, searched and didnt find any posts pertaining to flashing without serial, my mark IV doesnt have a serial connection and my laptop only has usb connections. any help would be great. Also, downloading infusions isnt working so i either need to flash the firmware again or downgrade. The percent bars say 114% and 130% while trying to download and it just sits there. And even though i have a WAN connection the LED doesnt light up. any help would be great! thanks guys
