trying to upgrade PogoPlug E02 (4 replies)

I was following the UBoot instructions from an older pogoplug I had set up here back in 2014-15, I think the pendrive eventually went bad. I was still able to boot into the stock pogo OS and was following these instructions . I noticed I didn't have an /boot folder towards the end, setup netconsole and rebooted. Below is the output from booting.
Where did I go wrong?
