FOR FLASHING- TOTAL RESTORE: (Do this if your phone does not boot up) - you can say this one gives you the "New" OS, and of course deletes all user info

How to do it:
1) Remove the battery, and then wait for about 20 min or so before putting it back

2) Press and hold these three keys together -Green dial key, Star key[*], Three key [3]

3) switch ON the phone.

4) Do not let go the three keys until you see the WELCOME screen displayed and just let it complete the boot process
