You can fix it by USB :
You need to Download the Update MS-Diamond-Z2_V3.4.1_2018-10-24 
And put it in USB Drive in Folder  

Then Change both the name of Folder and the name of update File to 

Folder : RomUpdate 

File:      RomUpdate

Then turn On  your Mediastar Z2 while you are pressing the Power button in Front till reciver Screen Show update

Then keep your hands away 
And Receiver will do the Update Automatically
