NOKIA 6600 FORMATING
If you face problems like nokia 6600 gallery is not opening, camera is not working, Bluetooth device of mobile is not working,mobile is operating much slowly, u’r celll is infested by viruses like commwarior (we’ve an alternate solution for this )..and many other problems then first RESET your phone so that it’ll get theoriginal factory settings. First format by secret codes here and then if the codes failed go for full hard formatting via keys (step 3). Resetting just solves many problems and if the problem still persists go for other alternatives found in our ‘PROBLEM SOLVER’.
RESETTING PHONE BY NOKIA SECRET CODES (steps 1 and 2)
1st step : SOFT RESETTING NOKIA 6600
A Soft-reset is the process of resetting all the settings of the phone to the factory default! No applications are deleted.
Take backups of ur phone books,calender and others, then simply enter the code
*#7780#
It will ask for “Restore all phone settings-phone’ll restart….”
Then it asks for security code enter ur security code whose default value is 12345 then the phone is resetted after restart.The phone will be restored to the time when you purchased the phone.Default apps are not deleted.
2nd step : HARD RESETTING BY CODE
A Hard-reset is like formatting a memory disk. It formats the phone memory. Everything that has been installed other than default apps at d time of purchase are deleted.The phone’s setting will be restored to the time when you purchased the phone.Default apps are not deleted.
Just enter the code-
*#7370#
Then it asks for security code enter ur security code whose deafault value is 12345 ….then proceed as in previous step…..
NOTE:
The battery must be full or the charger has to be connected to the phone so that it does not run out of power and make the phone unusable.
Take backup of the contacts and other important data in MMC .
FLASHING
3rd step :’FLASHING 6600′ : ANOTHER METHOD FOR HARD FULL FORMATTING
If any of the above methods failed to make your phone formatted then try this step-mainly try this step if the problems are following-blank screen phone unable to boot, phone is only able to boot-up to Nokia screen ,unable to uninstall any installed software, unable to delete certain files on C drive(phone memory).This step is known as flashing of phone. Always do this step at last (after 1st 2 steps are over and u are not successfull) as these problems might be solved by resetting using codes.
To format the (restore factory settings) phone here is a way .
1. Make sure you phone is fully charged. (At minimum 3/4 of bettery should be left)
2. Backup your contacts list and personal files to MMC memory card (if possible).
3. Switch-off your 6600 phone.
4. Press and hold these three keys together
-Green dial key,-Star key (*)-Three key (3)
then press the power on/off to swtich on the 6600 phone.
Do not let go the three keys until you see the “formatting” screen displayed
5. After a few minutes, the format will be complete. Your 6600 will now be at its original factory settings (It will reach the same state as that in when you purchased it). All inbuilt applications provided by nokia will not be deleted)
I’ve written this tutorials after many case studies with cells of my friends. I’ve collected a lot of informations from internet by searching and from communities like “nokia 6600 “ in  I’ve also used all above procedures to my nokia 6600 successfully.
DISCLAIMER: I will not be held responsible for anything that happens to your phone as a result of following my guide. Use this guide at your own discretion and risk.
