ATJ2051H Firmware
 

I have a MP4 hacked player that boasted 4G, but is actually 500M. Chip is ATJ2051H. I didn't read enough before I attempted to update the firmware because the player was rebooting constantly. SO, I have a player that I finally got back to a blue screen after following the dead player recovery guide on this site. I have attempted to upgrade the firmware from a model exactly like mine, but when I am in recovery mode it says the firmware is invalid. How do I get a full dump of the firmware? The MP4 player I have is exactly like the one posted here:
