I have a nokia 5220 music express and forgot my sercurity code, please help to master reset the phone, ime# 3536620102490959 urgently please?

use this master reset shortcut to reset your phone to the factory state. Press and hold these combination of keys at the same time: on/off button, green/call answer button, the *button, and the number 3 button. Press and hold these keys for at least 2 minutes or until the date and time settings or location settings appears on screen with the default nokia theme.
the phone must be off before doing this, so this combination turns it on and also reset it.
Hope this helps.

Reset your phone. Enter *#7370# from standby screen. Then it request the code is 12345. Or turn off your phone, and then hold *+3+ call button (green button). And turn on your phone. Keep holding until the word nokia is appearing.
CAUTION: IT WILL DELET ALL OF YOUR DATA IN PHONE MEMORY. So, please make a backup first. Please rate us in fixya if i'm helpful

I have nokia c5 but web does not open,shows errer not enough memory to perform operation,delete some data first. what is the solution and how to delete the data

This is what you get when you fill up the phone memory too much. There is not enough virtual memory to run the web application.
The best way to go about this is to do or run a complete format of your phone memory. It is quite useful for you to know that running a format would wipe out everything on your phone memory.
If you want to go ahead, you can follow the instructions below
1.- Basic Reset or Soft Reset This option restores the .ini files from the ROM.
Does not erase data (photos, videos, documents) nor applications from
a third party. Key Code *#7780# (click this combination of keys on the
keyboard in the mobile)
2.- Total Reset or Hard Reset This option restores the original operating system from the ROM.
Formats the C: partition and deletes all data including the memory
card. Key Code *#7370# (click this combination of keys on the keyboard
in the mobile)

You can also reset the phone by doing the 3 button reset.
To do this, you have to turn off your phone.
Hold the *(asterisk) button + the green/call button and the number 3 button then turn on the phone whilst holding these 3 buttons. Wait till the phone comes up with the initial set-up screen.
Note that you must have full battery or have your phone connected to power before doing this.
Hope this solution was helpful? Please comment for more information

3 ways to format N95 are :-

First: if the phone menus work there is a; go to menu -> tools -> settings -> general -> factory restore. note: the defualt code is 12345
Seconed method requires you to enter these into the dial number area. Nokia Code : *#7370# : NOKIA Format phone (Soft Reset)
Nokia Code : *#7780# : NOKIA Factory Reset (Hard Reset)

Found these in the N95USERS fourm. Note: the defualt code is 12345

Third: is a button combination the needs to be done during the phone powering on
Hold down. 3, * and Green Call button While holding this combination press the power button once to start the phone Note: this does not require any codes; if this works the phone will prompt you to be set up again

Soft/hard reset combination keys doesnt work for nokia 6280

try this for soft reset

12345 is a standard code and 00000, but if you change it and you have forgotten your unlock code, you'll just have to reformat it

key combination which is used to hard reset the phone (similar to #*7370). It is useful in some cases, for example when the phone cannot reboot.

The trick is
Switch off the phone.
Hold down the following three buttons: Green (call answer) button, * button, and ‘3′ button
While holding these buttons, press the power button and switch on the phone
When the message ‘Formatting’ appears on the screen, release all of the buttons...

reformatting your phone will delete all your data and also will restore all the defaults of your phone, and any corrupted application will be reinstalled, but if the formating doesn't work, you'll just have to re flash it, the safe way is to go to a near repair shop of your phone and have then to re flash your phone,
