SONY NWD-B105 it says
BOOT ERROR and it shut down
Hey,FRIEND!! I actually found out a solution regarding on the problem by myself,accidentally, lol. As you guys mentioned, everytime you try to play a song, the device automatically turned off itself. Now, i'll tell the trick behind. You may simply hold the "Play/Pause" button and don't let it go. At the mean time,try to select song by pressing "Next/Previous" button. The moment you select song, you let go the "Play/Pause" and hold it on again within a million second (that's mean you need to do it damn fast). Right now, you're listening your favourite song,but you can't just let your thumb keep pressing the "Play/Pause" button,right? Here is the "HOLD" button comes to work, you flip the "HOLD" button to activate it. TADA! You can let go your thumb and relax yourself with the songs playing. The battery will eventually dies out,nevermind though, you always can recharge it. Repeating these steps everytime you want to listen songs, my mp3 actually fixed on its own. I admit that it's still not the best solution it appears to be,but you guys should really try it out, you're not just going to give up your mp3 like that,agree? haha, all the best and good luck!
IT IS EFFECTIVE, PLS RATE IT, THANKS
