turn off your phone first then follow the steps

how to format nokia 5800 xpressmusic

1. *#7780# – Restore factory settings – resets all the settings to the default ( you will not lose any data)
Make sure you back up your data as you will lose all of it when you perform option 2 or 3 on this list. The default code for all operations listed here is 12345

2. *#7370# – Reformat your phone

3. This you perform as a last resort. Nothing else is working.If the phone is not showing any activity, proceed with hard formatting , turn off your phone, hold the following buttons while pressing the power button. (the default code is 12345)
hard reset – hold the following buttons *, 3 (number button) and talk/green key. turn on the phone and do not release those buttons until you see the Nokia boot up screen. once you feel the phone power up you can let go off the power button while still holding all three buttons ( for Nokia 5800XM – use the following buttons to do a hard reset, GREEN/RED/CAMERA keys pressed all at once on power up. this will only work on 5800′s that have firmware version 20… and up. )

If these codes are not working the only thing for you to do is contact your Nokia Care Center/Service for assistance.
