Upgrade failure prior to device reload

Perform these steps if upgrade fails prior to device reload.

1. Examine your installation details:
   • Verify the command arguments and the upgrade path options.
   • Is there a requirement to install intermediate firmware before installing the desired firmware?
   • Is there a command option requirement?
2. Examine if the build downloaded correctly—by comparing md5sum for the downloaded *.tar file with the source.
3. Redo your extraction of the *.tar file, preferably under Linux.
   

   Note

   If you need to extract the *.tar file unders MS Windows, use the 7-Zip shareware utility.
4. Perform the upgrade.
   

   Note

   If the same failure occurs, contact your device support provider.
