Hello,
- On some forums it is reported that you can make your NOkia 97 work smoothly (after a crash) without formatting it;
- Turn off your phone
- Connect the charger
- Remove the charger when the screen lights up and wait until it goes off.
- Turn on the phone immediately after using the Power button on top.
- After the vibration at start up, plug-in the charger.
For formating follow these Just follow the steps
Make a backup of contacts in your another sim.
Switch-off your phone.
1. Press and hold three keys at a time;it is called "3 finger reset" which is depress these three keys simultaneously "*" "3"
"green phone" and then power on phone whilst keeping those same three keys depressed until you see formatting.
If you dont understand, again follow the step.
You will use three finger for pres three keys ."green phone"+ "3" +star( *) and pres the power on switch.
All switch will be pressed at a time.
Soon an formatting text, will appear ,then stop pressing those switch,
Remember.
2. After a few minutes when the Full phone formatting completed, your phone will back to original system and factory
stetting.
Hope this helps.
