ah ha! Got it sorted. So, the screen going blank was very odd. turns out after sending reboot, that state is two things
1. blank screen with not indication of being powered on
2. persistent through cutting the power (disconnecting battery)
So, seemingly, the devices is totally non-functional. The issue was, in the linux VM I am using, I had to go manually select the USB devices because the identifier changed from the prior Amazon device to a mediatek device. So it was in the right state, I linux just didn't auto connect to the new USB device.
All good the in the hood. continued and worked just fine. Just PSA to others, that boot state seems like the device is just off!
Are you unlocked, TWRP installed and rooted?
