Freezing Sagem Dbox2 1xI , Please help

Hi all,
Recently bought a dbox2 plugged it in and scanned for channels. Got loads of channels but the picture kept freezing, sound seemed to work. Flashed a commando 2.0 then sportster 1.75 image on to the box, found 300 channels with the sportster image but again the channels keep freezing but the sound seems ok.

changed the ucodes trying both 001A and 0014, and changed evocams but neither seems to solve the problem.

Dont know what to do next, can anyone help?
all help greatly appreciated!

 

open the box up and unplug the modem cable from the main motherboard.

 

Should everyone unplug the modem cable or only if it is causing problems?

Cheers

 

Hi, i have already removed the modem and it made no difference at all. really dont know wat to do next
