N8487B (ALI M3721) Firmware Dump Tool

[thameesha7]

Hi

I Have a new receiver Coship N8784B
this receiver build with the ALI M3721 chip I need to dump the firmware of this device
is their any tool to get the firmware backup of this device using RS232 serial connection
I try few erom update tools to dump it but all the tools give me this message "set stb memory error" and stopped working.
when i read few forms article they are said this happening because of the mismatch of the chip and the tool so
If you have any tool support this chip please attach it to this post

Thanks.
