With the format possibilities of the 3 key combination and the *#7370# hard-reset code, the Mass Memory and the Phone Memory get wiped. Often users, including me – wish to delete just the Phone Memory. An application that Nokia N8 users should know if you play with it often, is Phoenix : with this same application, the user can any drive of their choice.
It is necessary to connect the Nokia N8 with the USB cable in Ovi Suite Mode and start Phoenix. Then proceed to scan your device, then select local or test mode and select file system format which can be found under product. Make sure that Symbian APE is selected on the new window, choose the drive you wish to format, select format method and press start.
