okay so wrote a post and someone was kind enough to answer.
I basically wrote that my MP4 player had the hour-glass screen and nothing would happened. They told me it was due to corrupt firmware.
So I'm here to see if someone can help me.
This is a pix of the board
mp4 player
How long does the board number have to be?
I really don't see anyway to remove my battery to see it.
It's glued together, if I do remove the battery I think the buttons would just fall off.
Hopefully this is of use
