hi
unfortunately unless you have the original firmware for your player then modding is impossible, you need to be 100000% sure you hve te right firmware, do not rely on the look of your player, therr are so many different manufacturers of this type of player all with different firmwares
see this link for a mild warning

basically it a very difficult to impossible task to find the right firmware for these types of players, and risky, at the moment you may just be better to enjoy the player until it breas down then make sure your next player is one that can be modded easily
cheers and sorry if this is a bit of a dowwner, but i just hate the thought of people bricking these players
