Unlike old S60V3 Nokia symbian phones that use the same key combination for hard resetting, newer Nokia screen touch devices use different key combinations to perform a hard reset. Performing a hard reset restores the original operating system from the ROM (Read Only Memory). You may want to restore your phone to factory settings for many reasons:
1. Slow operating system
2. Virus attack
3. Boot -up failure with ‘contact the retailer‘ error message
4. Incompatible applications that can’t be fully removed
5. General system error
Now, before you perform a hard reset on your Nokia N8 or any symbian smartphone
you’re using, you should back up your personal data and files as you
will lose everything on the phone. Nokia Maps and Ovi store may also be
gone after performing the operation.
There are many reasons beyond the ones I listed above and before
running to a phone specialist, you can fix the problem yourself and save
some time. There are actually two methods to do this:
If you can still access the menu to perform basic operations
For Nokia N8, Nokia 5800, Nokia N97, Nokia C6, C5, E8, E6 and almost all Nokia phones (both symbian and series 40), there’s a code that works generally if you can still access the menu and operate the phone.
- Power on the phone
- At the home screen, press *#7370#
- Enter your phone security code and the phone restarts.
It boots up with the default factory settings restored.
Now, If you can’t access the phone normally or it won’t boot up due
to certain reasons, you need to use some key combinations to get your
symbian device working again.
