[split] Is this KODI Box useless?

I bought an MXQ box, which uses the MBOX launcher and am now unable to watch most of the tv programs we like to watch. I have no idea how to download the 17.1 Krypton onto it. I tried to do it using the tv, but had no success (because I have no idea about what I am doing) and I also took the chip out of the box and tried to download the Krypton onto it using my computer hard drive.
Any help would be much appreciated.
Thanks,
Greg
