Its very simple just press *#7370#. Then it requests for the security key whic is 12345 by default or enter your security code if you have changed the security code.. Or turn off your phone, hold *+#+call button (green button) and then turn on your phone. Keep holding until the word nokia is appearing. Please note that all the data on your phone will be deleted so kindly make a back up. Kindly rate us in fixya if i am helpful
Hi,Turn on unit until the red light flashes and the error code(E 73) shows up on the screen. Next insert toothpicks in the back of the console(while unit is running) into the cooling fans, this is to suppose to overheat the console and start two red lights flashing. Turn off console when this happens(unplug all cords from console) and turn the system back on. This solution will fix your problem for sure.Thank you!
there are many causes identify it and your problem will be solved
1) check in the options you might have turned it off if so turn it on
2) may be due to firmware problem so fix the firmware problem you can give the "restore factory settings" this will fix all your firmware problems
if you still persist the same problem
3) if you are good at opening then open the handset and check the flash light is in good condition or not and also check is there in loose contact .. if so make it right..if the flash light is dead then replacing that will solve your problem ..
