NEWBIE ADVISE FOR UPDATE PROBLEMS

so long story short. I got a Zidoo x6 about a year ago and did all the install. but my internet sucked to I just never used it. I got my router replaced so I plugged it in and loved it.
then I got the message to upgrade to kodi 17 and everything went downhill. i uninstalled it and the reinstall didn’t go well.
i can only add cbs as a channel and nothing else is there.
im not using a computer just the usb plug in and the Zidoo box.

any ideas on what i didn’t do? or what i can do going forward.

and thanks for any help ahead of time.
