fyi dremos, he has a copy of the onda that he bought in Chinatown from a non reputable source. the likelyhood of this being a real or OEM onda vx858 is very slim
well, from what I have read and seen, there are many chinese makers coping the onda style and interface for these itouch clones.
if the player is not branded by Onda or bought from a reputable source then i wouldnt even try to "upgrade" the firmware, because with the number of copies out there, there is a chance that it wont work.
but hey, i dont claim to know everything, i just know even the OEM onda players were having great deals of problems upgrading the firmware because the manufacture decided to stop using onda's firmware and create their own, per MP4nation.net

and even then, their is no guarantee the non onda firmware will work.
so like i said, if its not broke, dont fix it
