My SCS-26UC4 is bricked

As a note, I bricked my unit. Inside U-Boot, in the MDOC interface, I picked a menu item Update/Verify. To note, this isn't a menu: it updates, and then it verifies. Since I hadn't loaded anything explicitly, it loaded garbage to the preboot environment (IPL or Initial Program Load). This happened a while ago,  and hadn't posted about it. This is actually my second unit, as I bought one from the Verizon Store, then returned it as I found one $100 cheaper. Anything from here on out is static analysis, or analysis of the device without the CPU running.
