If you get the following error while trying to update the firmware on a Nokia Phone…

Nokia Software Updater has attempted to connect to the internet but has failed three times. This could be because of a poor-quality, slow or intermitent internet connection, or restrictions due to a firewall.

If requested by your firewall, Nokia Software updater needs the following applications to gain access to the internet:
nsl_host_process.exe
nsu_ui_client.exe

Try setting your default browser to Internet Explorer.

If you still have trouble, open Internet Explorer and make sure that “Work Offline” is NOT ticked.

All should work fine after this…
