Is it default that players with fw 9.0.50 have ACU7513 chip
Because my 1.8" 2gb ipod nano look mp4 player was faulty on arrival i had to open it, and found quicly the defect, it was a defective flatcable between the button/charge/usb board and the mainboard, it was easy to resolder it.
So now the player was open i noticed that there was an ACU7513 chip in it
And it hase firmware 9.0.50, is that why other firmware lower than 9.0.50 don't work on this player?
