i6+ on iOS 12.4.3 won't demote

[arinc9]

What device + iOS version are you on? i6+ + iOS 12.4.3

What checkra1n version are you using? 0.9.1 What are the steps to reproduce the issue?

1. checkra1n_gui -d

What do you expect, and what is happening instead? It's stuck on exploiting stage It's either I need a special hardware in the middle or it just hangs.

Any other info, error logs, screenshots, ...?

Arncs-iMac:~ arinc9$ checkra1n -d

Granted, the log doesn't reflect well what's happening, but if you run with -d -v you will see that it actually enters demoted state, and then just stays there, waiting for a debugger to attach. So this is in fact working as intended.
