Being such a huge Nokia N97 fan, I am often asked how to hard reset a Nokia N97 and thought that it would be best to post this on my blog.

Performing a hard reset on your Nokia N97 will essentially wipe all the data on the phone memory  and return all the settings back to default, which is the equivalent of performing a format on your Nokia N97 phone memory. Please also note that the mass memory is left untouched during this process and retain your data (as per my experiments)

It is highly recommended that you backup your data from your Nokia N97 using the backup utility within the Ovi Desktop client before performing a hard reset.

Performing this is at your own risk!

After backing up your phone, switch it off.

Then hold Caps/Shift, Delete and Space Bar. While holding these 3 buttons, press the power key and hold, until you hear the Nokia welcome tone. This process takes a few seconds and you have to hold all four buttons down during this process.

Remember that you always have the option of a soft reset, which will in essence reset the phones settings back to default without changing any data. To do this, simply go to Settings > Phone > Phone Management > Factory Settings.
