The md5 hash calculation of the update file : DPOD-update-<version number>.md5

Copy the software update to the DPOD server

Copy the update files to the following directory on the DPOD server :

/installs/update/fix/TODO

If the directory is missing for some reason, please re create it :

mkdir -p /installs/update/fix/TODO

Install the software update

Run the following command from the location you downloaded the update files to.

MonTierUpdateInstaller.sh -u DPOD-update-<version number>.sfs -s DPOD-update-<version number>.md5

For example:

MonTierUpdateInstaller.sh -u DPOD-update-1_5_0.sfs -s DPOD-update-1_5_0.md5

After running the command you will be prompted to confirm the software update process. press "Y" to confirm or "N" to abort.
