Didn't you activate trusted person settings? And now you've a headache to remember the security code you've set up ! You can retrieve the forgotten security code using Nemesis Software Suite.

How?

- Download and install NSS

- Connect the N9 in "Sync and connect" mode (you may need to wait for the driver to install)

- Run Nemesis Service Suite (NSS)

- Click on "Scan for new devices" (top right hand button)

- Click on "Phone info" button

- Click on "Scan" button.

- Switch to the "Permanent Memory" tab.

- Click on "Read" button and let the program read memory contents. When it finishes, in the last line in the status window it will inform you about the location of the log file containing memory contents.

- Go to that location and open the file, e.g. with Windows Notepad.

- Find [308]

- Scroll down a little bit until you see a line starting with 5= followed by a numerical string, e.g. 5=31323334350000000000

- When you remove the "3" digits on ODD locations in that string, you'll get the security code. E.g :

31323334350000000000 = 12345 i.e. your forgotten security code (of course this is just the example showing the unchanged factory code).
