This looks far better than the combination of fresh flash and no mounted partitions. Still it is too early to tell if software or hardware is borked.

But you need some kind of root enabling packages, be it rootsh, which i prefer, or sudser or openssh.
You need to check the file systems and, may be, repair them, You need to mount partitions and check their content to evaluate the success of the flash of the firmware. Please uninstall some applications in Hildon Application Manager to have space to install any of the suggested root enabling packages.
