don´t upgrade last version MKT1100AHx2

Hi,
We have an MKT 1100AHx2, it version is 6.39. We want to update it to the last version of the POWERPC Model (versión 6.43.4).
We are doing it through the normal method of update:

  • FILES LIST - drag files - reboot
    But it doesn´t.
    Someone has happened something like this?

Thank you!

What’s in the log?
