I had my problem solved today. I did a reset for the thousandth time, but this time as soon as I connected to the Internet during the configuration the box restarted by itself, I went back to the configuration menu to finish, when I went to update it updated the version and finally the necessary update appeared, IPTV working perfectly, already properly configured. Thank you all for the support and to those who actually solved the problem.
Nice to know, please what model of device is this?
