Removing Custom Kodi Add-Ons From Android Box

Hi,

I have an Android box that came with Kodi on it but this version of Kodi allows to watch anything and everything I want and I’m wondering what the steps would be to bring it back to it’s original form of Android.

I am unaware of the model of the device other than the “MX” label it has on the surface of the box.

Thank you.
