I was see on the youtube some tutorials and i was remeber that i never use it so much this mp4 player in this 2 years i mean i never charge the battery i was only plugg it to the computer usb transfer some data on it and turn it off could be the dead battery and that why does nt want to start??
i mean even if i plug it to the computer with usb cable and if the battery its dead that why does nt want to start?? by start i mean to enter in the Menu
because now all i have its a blue screen and sometimes that hourglass and that it does nt want to enter in the menu PLEASE IF SOMEONE KNOWS COULD TELL ME IF ITS THE BATTERY I CAN CHANGE IT BUT DOES NT WRITE ANYTHING ON MY BATTERY I DONT EVEN KNOW WHAT POWER HAS..... MAYBE SOMEONE CAN TELL TOO HOW TO FIND OR MESURE IT THANK YOU VERY VERY MUCHHHH!!

first install the mp3 player utilities v 3.68 then connect the mp4 and you will see a Found New Hardware screen after you give all you pc will recognize it as adfu device then is ready to install the firmware then open the mp3 player upgrade tool and a window of recovery mode look for the firmware I sent you to load and then you give in and begin upgrading the firmware is installed and will extract safely disconnect it and just turn on the mp4 should work with this good luck ¡
