I did some research and it seems that “kbox” is a pre-loaded Android box with a lot of kodi add ons. Over time, add ons are shut down, they change etc, so a preloaded kodi box will not work at some point.
Personally, I would erase the entire content and start from scratch and install the add ons one needs. Keep it minimalistic. I also would not upload a “build”, as this is overloaded with useless stuff.

Nathan has a great guide on how to set up a kodi.

We have a K-box we bought from Westcoast Streaming. We can not get any streams for the tv shows we watch now. can you help us.

Why does my kodi box not let me get into shows?  It says cancelling sources?

Is there any updates the Kbox I have not been able to contact west coast streaming support.

I have a Kbox is there any updates I have not been able to contact the support for West Coast streaming.

You were right, I deleted all my IP addresses and just entered my wifi password.  And now I am connected and was able to download a lot of add-ons also, by using the directions from your web site.  I so appreciate your help and thoughtfulness.  Thank you very much.  

I have an older K Box (2015) I think. My home screen doesn’t look the way it used to look. There are no available updates but when I go to movies or tv shows there is nothing available. I can only watch what I have saved in “Favourites”
Can you help me? Is there a new cloud word that I can use?

So my Kbox showed an update due so I ran it. I am now showing Krypton and a whole new look when it rebooted. Nothing will work. All the movie and TV sources are blank. Anyone else having this issue?
