Can't dowload songs from PC to my N10. This problem occured after entering service mode and probably changing some data there. Could anyone tell me which menus in the service mode are responsible for net md function and their right settings? Oh, and another problem: when i connect my player to the charger (not original) the unit shows Hi DC in, though by some manipulations i'm able to charge the player. The needed voltage for charging is 6v. I tested my charger with a voltmeter and it's ok. The most strange thing about this is that, when setting the voltage on the charger to 4.5v the red light lights up and unit begins to show that it's charging, but actually it is not. Sorry for my English, i'm from Russia
