If you get this message:
Invalid package – This package is not valid update package. Do you want to try another one?
while trying to update a Vista console.

  1. Check that you are downloading the correct update package for your console. There are two packages, one for the L5 and newer I3 consoles and another for the T4, T2 and older I3s
  2. Check that the file is actually a .tgz file. Sometimes it gets renamed during the download process to .tar or other file type. If this you will need to change the settings on your browser.
  3. Check that the size of the file corresponds to the size shown on the download page. The update package is a compressed file and sometimes gets automatically expanded after being downloaded. Vista will only accept the compressed file
