how to use the rom

Hi guys i am new in the forum. I downloaded the rom file for the echosmart dsb-771, but i dont know how to upload it to my decoder. I have a ready (fat32 formatted) usb, but i dont know what do.
Its the first time i try to do something like that.

Thank you for your time.

Which is the latest firmware for echo 791? v3.80?
and the latest rom boot please.
