crosh no longer runs sudo, vt-2 doesn't have 'su'

[Waffull]

It's been a while since these instructions have been updated. It appears chrome has worked to secure itself even more. You can no longer use sudo in crosh. You can go into VT-2, but no way to install su and it's not built in. So after getting the suzyq cable connected, there's no way to send commands to cr50 at /dev/ttyUSB0

Does anyone know how to proceed through this step at this point?

I appreciate any help.
