MAG 250/254 writing a software to remotely setup ntpserver

I need to update to the new stalker version 5.1.0 on my MAG 250/254. Unfortunately i was not aware that I had to set the ntp server, so I have lots of STBs in clients home without the correct settings. So when I attempted to upgrade to version 5.1.0 my clients devices locked due to a synchronization problem. Setting up each client individually will be almost impossible as I will be forced to recall boxes thats been shipped all over the world. Informir have advised me to attempt the below things: Reasons such problem: 1. The STB hasn't ntp url server Solution a. Specify ntpserver in Settings/System settings/Servers/General (I cant do this individually). b. By side your Stalker MW specify next variables in [login to view URL] stb_ntp_server = <your_ntp_server> overwrite_stb_ntp_server = false/true c. Create firmware with your ntp server and URL of your portal. If you have custom image you can create autoupdate from Stalker MW. I am looking for someone who could fix this problem and update my stalker to version 5.1.0
