Tutorial : How to hard reset Nokia N900

UPDATE:

You will need:

• N900 (Charge up to at least 50%)
• PC
• Micro USB Cable
• Your IMEI number (go to settings>About Product or under your N900 battery)

Before you look at the instructions:

Backup the N900!

This process will wipe your photos and videos. Save precious data onto your computer. Simply drag and drop them over.

For content such as contacts/settings/bookmarks/applications list, use the Backup application on the N900, but backup to a memory card only. Do not back up onto N900 as that will get wiped.

You can drag files back over and restore backup from memory card afterwards.
