What I know it should be 3 partitions. Here in your example the rootfs is missing.

Did the flasher were sending kernel image and initfs image successful?

With my N950 it sending the files but nothing happens. So it was only working with --enable-rd-mode --set-rd-flags=serial-console.

Did you get a warranty warning on N9?

But there should be somewhere a moslo rescue kernel with usb network and telnet from juiceme. I think this could be better.
