Recovery of bricked unit

Douglas

In setting up a new oak4 d pro w unit, a flashing of the os has seemingly bricked the unit. I don't see any led light, no device in adb devices, no device from lsusb. The process for reprogramming the os was the same as I have successfully performed on another old oak4 d pro unit previously. I was flashing 1.6.0 from luxonis_os_rvc4_debug-1.6.0.tar.xz linked https://rvc4.docs.luxonis.com/software/depthai-components/luxonis-os/#Luxonis%20OS-Updating%20OS-Full%20OS%20Flash

What is the correct way to go about resolving this? I see there is a reset pin. I don't see any specific instructions for v4 devices, but in other issues I see described to push the reset button, boot up the device, and then let go of the reset button. After doing this, I don't see any usb device via lsusb, is there some other process?
