magatron002, About 99 percent of these players are unbranded. Wholesalers who buy large quantities can get their players labeled but most do not. Most of the so called manufacturers that put these player together do just that they source components like mainboards, cases, LCD panels, batteries etc from various different places usually based on price and there are many suppliers, then they just assemble in sweat shops. This means that parts constantly change as they source cheaper and newer components so there is no way to define a players make.
At wholsalers web sites you can find photo galleries of all the players they make but generally they do not hold them in stock, once a bulk order is placed they then source the parts and produce the players prior to shipment. This means that even if a buyer goes back and orders another 1000 of the same model they may have the same external casing but the internal and firmware may not be the same.
The short answer to your question is that there is no way to identify exactly what type of MP3 Player you have as the firmware is generic and labeled the same on them all except for version numbers.
