I've attached full captures of the serial console on the working PE and the broken PE with EE firmware. (note the "Edge>" prompt on the broken one vs the "EdgeJr>" prompt on the working one)

Things to note...

Same exact hardware shows a bit different init screen... DRAM size.

Working PE:

Where to go from here? I'm not an android hacker (yet), lots of u-boot options, like Solaris OpenBoot... so I imagine something looks here to try to force a firmware/rom flash. I'm open to suggestions?!
