How to Reset or Format S60v2, S60v3, S60v5 Mobiles

If you like to test every new game and every new application on your mobile
handset, you will/have
face(ed) a common
situation where you need
to reset or format your
mobile device to make it as new as it was when you
bought it. Reset a s60vc,s60v3
mobile is easy if you know
the reset code, but
resetting new touch
mobiles like N97 and 5800 which don 't have physical keyboards seems very
difficult if you don 't know the procedure. Here I'm
explaining the way: The first two methods are
standard for all symbian
mobile phones, but the
third one is only for touch
mobiles.

1. Soft Reset/Normal Reset: With this method,
the mobile setting are
restored to factory
settings. But it does not
remove applications , games or anything installed. To do
this reset press *#7780#.

2. Deep Reset: It is the most common way to reset your
mobile. It will erase all the
bugs and errors in your
phone including all installed
applications and games on
your phone memory. *#7370#

3. Hard Reset/Format: If due to any problem you
are not able to go to the
screen of your mobile to
enter the above mentioned
codes, then you will have
to do the hard reset or to format it. Symbian so0v2,S60v3
and S60v5 mobiles have
different method for reset
but N97 and 5800 have
different.

a. To reset the mobiles other than N97 and 5800,
keep pressed the following
three keys on your mobile
keypad and restart your
phone while still pressed
these keys. * + 3 + Call button (green button).

b. For Nokia 5800 XM: In this case, press the keys at
once Red (End) + Green
(call) + Photocamera
Button and hold and switch
on the mobile.

c. For Nokia N97: Press both Shift keys + space bar
and BackShift, hold, turn on the phone. Note: All data will be lost during this process, so
back up all your data
before you go for these
procedures.
