JRunner crashes when comparing nands?

[harry123ab]

Ok so i have just installed the demon to my xbox before i install any glitch chips so i can read and write the nand to test for successful boots, it reads two nands then gets stuck on comparing and crashes, the demon is set to pc mode and is connected through micro usb. Here is the error log:

System.NullReferenceException: Object reference not set to an instance of an object.

Or can anyone tell me how to properly read the nand with the demon. I have everything soldered on the demon and connected the ribbon cable to the nand switcher then what?
Edit: Is the demon supposed to light up when i connect power and to pc?

the led signifies the demons onboard nand is selected, if led is off the xbox nand will be in use

is the demon icon showing up in JR?

if you haven't yet written a nand to the demon then it will be blank

so led off to read the xbox nand!

Jrunner also crashed on me when comparing nands.. I just read xbox nand, then wrote that to demon.. then booted console on both demon and original and made sure it worked

I had the same problem. Try using a different version of j runner.
