How to reset NOKIA 5610d-1 to factory settings?
I tryed to enter *#7780# but i have no time to enter all this digits. I tryed 100 or 200 times and now i can enter this code too fast to see next screen and security code request. But it's no more possible to enter the code before the phone goes down.
The problem comes with some theme installed. Batteryes are charget completely.
I heared something about safe mode, but can't find any information for this model.
Not clear what you mean by 'The problem comes with some theme installed...' If the problem is with some particular theme.. then use Other themes.. Either do not use or un-install these themes.. If you are not getting time for all this as the phone switches off before you do anything.. then try switching ON with the charger connected..
If this also does not work then you may have to get the phone checked at Nokia Care...
