Chromebook stuck on white screen (Of death?) after installing RW_LEGACY Firmware

I’ve been following along with Mrchromebox’s “Getting started” documentation (Getting Started | MrChromebox.tech) but after installing the RW_LEGACY Firmware I rebooted my device and now it’s stuck on a white screen.
I have not yet tried to do anything more for fear of bricking the device.

Is this salvageable? How so? or is by device already bricked?
My boardname is MAGMA in-case that matters

This is probably just due to powerd being disabled while running the firmware script to prevent automatic suspend, but has the side effect of preventing chromeos from rebooting normally. You should be able to force power off the device and turn it back on.
