The firmware 2.51 is the right one to use in a premium hd jynxbox ?

[marcel.crash]

the 251 is for the original jynxbox ultra HD v1 or v2 it has a clone kill in the file . so if there is a chance that you have a clone don't load that file .
if you just bought the receiver check system info and see if the file is already loaded . they usually come pre loaded

The system info :
Jynxbox P1
loader 1.2.20
Hardware 1.0.3
Database 1.0.1
Firmware 1.2.39

it has the 239 and that is a working file and clone safe . you should be good to go
