Btw, I have received 3 of this player
http://www.tinydeal.com/index.php?ma...roducts_id=427 from TinyDeal. These players came with a bad programmed firmware: the sound volume is not adjustable anyway. I reported this problem at TinyDeal, but they didn't gave a useful answer. I experienced that always, they have no competent employees to solve technical problems. They providing some downloadable firmwares not compatible with the actual players, just brick them, if anybody make an update with them.
