Installing a service pack is a very simple task that can be performed by following these steps:
1. Download BES 4.1 SP 5 using this
LINK
2. Log onto the BES using the BlackBerry Service Account (e.g. BESadmin)
3. Run the SP5 installer and follow the prompts. Don't change any options as it will detect the current configuration.
4. After the first stage of the update is completed you will be prompted to restart. Once the server has rebooted log onto the BES with the BlackBerry Service Account again and the installer will automatically launch.
5. Follow the prompts without changing any settings and just continue to press Next until you are prompted to start the services. Please note that the database upgrade screen may appear to freeze but this is normal and you should leave it even if it displays "Not Responding".
