Need firmware for ATJ2051N
 

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

Well I completely dismantled it and here is all the info on it.
It has a ATJ2051H , two Samsung K9F4G08U0A (512 Meg)memory chips, SP3767HN FM radio chip ,EU-BL-0020/68-07851 on the displayand a lithium ion polymer battery. Thats all there is other than a few descrete components.On the battery there is a bar code sticker that has:
20/16 MIW060203004
7J548PNFSJB MA004X/A
Also MP3 Upgrade Tool said it was a Wilson Co. version 3.5.37 before I overwrote the firmware. The firmware info screen displayed on the MP4 player had PMA300_010
2006/05/25
3.5.37
2006/07/20

With all this detail someone out there must have the proper firmware for me.
Thanks

radarshop , it is not possible to identify which firmware would work properly with your player as there is no proper versions control with the player manufacturers. So basically you'll need to try all the available v3.5.37 firmwares until you hit the right working one.

It's not an easy task, but that's often the only way to recover a dead player.
v3.5.37 firmwares here http://www.mympxplayer.org/actions-3537-dc16.html

And also try the v3.5.35 firmwares if all the v3.5.37 do not work. List here http://www.mympxplayer.org/actions-3535-dc15.html

What does the name "Actions" refer to? MP3 Upgrade said that mine had a version of "Wilson Co." What does that refer to?

Well I kept trying different firmwares until I have now locked it up. I can see the memory and and able to write to it with windows explorer but now when I try to send new firmware to it using the mp3 upgrade utility it will disconnect itself from the USB port everytime I try to connect. I then have to physically remove it from the USB port to get it to connect again through windows explorer. Any one know how I can get it to allow me to connect to it so I can try another firmware?

radarshop , i'll suggest you uninstall the current MP3 Utilities & install another version, see if the problem still occurs.

If it still occurs, then you'll need to perform the Dead Player Recovery guide here http://www.mympxplayer.org/dead-play...ide-vt567.html
It is normal to brick your player whilst testing with various firmwares. And you may need to perform the recovery guide a few times.
