Soft Reset

A Soft Reset will clear pending errors and bring your mobile phone back to its preset state by restoring the factory settings. To operate this function on your mobile, the code is: *#7380#

Hard Reset

Hard Resets are sometimes needed after the soft reset was performed but the problem was not resolved. Enter the code: *#7370# then press Yes to confirm initialization.

For the Hard Reset, it is recommended that you backup all info, such as phone numbers, contacts and any data you would like to keep.

If the Nokia Mobile Phone will not turn on, press these 3 buttons at the same time: ( on/off) + ( * ) + ( 3 ).

With these tips, you should be able to overcome your phone’s sluggish nature, giving you a working phone. For other problems, such as broken screens and keypads, please read my other posts.
