I have a Mag 250 STB provided by my ISP. It has proprietary software from the operator to watch their list of TV channels but I am still able to access the internal portal through their menu. Now I have loaded an IPTV list into the internal portal and save it. The list was of more than 10000 channels and now when I try to access that list my STB freezes and eventually I get only a black TV screen and an unresponsive STB. So, is there a way to delete the whole IPTV channel list from the internal portal considering that I cannot access the list to select them either one by one or the whole list as I did with smaller lists?
