Device disconnecting when attempting checkm8

[jonathanware]

Attemtping to dual boot. My command is ./pyboot.py -i iPhone8,2 13.5 -d disk0s1s6

The main issue I've been having is when it is attempting to run checkm8 for the first time. It times out due to not being able to find the DFU device. It seems that the device in DFU mode is disconnecting during that step and then failing to reconnect? I'm guessing that that's part of putting the device in PWNDFU mode or something. I've also had a popup saying that python has crashed during that step as well, but not every time.

I've only ever made it past that step twice. The first time I tried to run it and one other time.

I have an iPhone 6s+ with the N66mAP board running PyBoot Beta 0.6
