so i have this sony ns-11 128 mb mp3 player ,, which is originally Wilson .co .ltd !!!
when i plug it to usb , i can use it as a flash drive normally , the problem is that when i disconnect it it keeps about 2 seconds and then auto shutdown !
i tried to flash it with V43-SN320.fw as i saw the chip is atj2075 which is very similar to atj2085 but the MP3 Player Update Tool returning with "device not detected"
any help please
