kodi 17

Hi,

I installed kodi 17 from usb stick today, onto an android 5.1.1 box.

I am thinking that there is insufficient space for it to work correctly. I say this because when I open Kodi, I see the lefthand side menu, however in the main screen is a message that there is nothing in the libraries. I get the same for each category.

When I click on the Settings icon, I get a blank, black screen.

How can I reset everything and reinstall 16.1 – which was working (but not enough variety)?

Thank you

Wal
