The new Kodi versions would not work on the older Android Operating Systems.
So a team created the FTMC to replace Kodi and was able to work on older Android OS .... is why they look the same or similar.
FTMC is referred to as a 'fork' of Kodi
You could still use that FTMC if that is what you want.
You could find a version of it in apk file format and sideload that onto your T1
Use the File Manager/Browser to load an apk and install the app
An apk is a carrier of an app.
Think of an apk file as a suitcase with a pant suit inside, and the pant suite being the app
Or the FTMC may even be found in your onboard Market.
