Try this : download and install (Nokia Care Suite PST 5.0 2013.13.4.4) and (Nokia Data Package Manager) you no longer need Navifirm as Nokia has closed its servers to all but the latest update for your phone, in other words you no longer have the option to choose different firmware to install on your phone, wich is what Navifirm was for, the Nokia server will only allow the latest single firmware update for your model phone and the Nokia Data Package Manager is how you get it, Do Not Update the Nokia Care Suite Application Launcher or it will ask you for a pass word that only authorized Nokia employees have and be sure to check youtube and watch how to use properly (I have used these tools recently and they work) Navifirm is a waste of time at least untill Nokia opens its servers to the public again. Good Luck
