I decided to try to update my firmware on my 1 Gig MP4 player that looks like the following. It had Wilson Co. version 3.5.37 in it and was working fine other than it was coming up with the "VOIP locked needs update" message. I thought maybe if I reflashed it with a version of Wilson 3.5.37 I downloaded it might fix it. Well now it is dead. I have tried many different firmware files and still dead. Some gave a blue screen and some a black screen. It has only one samsung 1 gig memory chip. It has "Menu" on the top button and not "M". I do not know if this makes any any difference when it comes to firmware. It has a 1.5 " screen and the ATJ2051N. Again it looks like this one
