Zodiac DZR 1900CI .....

Hello,
I've understood that this decoder is a clone of Arion 1900CI and Ferguson 5018, i've found some files to update it in this splendid forum, now I'd like to know how to operate and ask you if there is a guide or if someone knows the proceedings and could help me. Thanks a lot in advance....
Ciao

Hello,
It all seemed to have gone well but unlikely my receiver didn't last more than 10 minutes, now is dead, nothing on the display e no connection port (com 1) anymore, I uploaded all the latest firms and every action taken was ok , once I plugged it back, it was dead....now what I ask to someone who knows is if, by chance, there is a program to relive it.
Thanks to anyone who answers to these questions.
