I used UniBeast 7.1.1 to create a bootable USB device.

I have also tried to run with -v -x as startup parameter. But then I got this error:

I have noticed a lot of people posting config.plist, so this is my file:

I hope somebody is kind enough to help me. I desperately need to make this work

Kind regards
