All files received will be treated as confidential and used for analysis only.
The NBU file is used by Nokia software in order to back up information from a Nokia phone. The information backed up will commonly include the contacts, calendars, alarms, and other data from the phone. This can be used to restore the data to either a phone which you are resetting, allowing you to restore the data to the same phone that you pulled the data from, or to a completely new phone.

I have a Nokia telephone model E61i. Unfortunately it does not work anymore. However I have a file with the name "E61i_2011-08-09.nbu" with 385 Mb. I have used the OVI program. I would like to know if your Noki Explorer could help me to recover the information in that file. I have tried to download your "Noki trial version" but it seems there is a problem. I would be grateful if you could help me with this matter. If you have some program to get the information in your facilities I could send you the nbu File.
