Seriously need help

Hello, I could really use some assistance in getting my KODI to do something. It used to let me watch films and tv shows. I haven’t used it in a while but I have no tv shows or anything. No apps etc. I have gone on youtube and tried to follow what they say, but I can’t even put it back to factory settings. I am so fed up with it but I don’t want to give up. Any help and advice would be greatly appreciated.

I have a KODI 14.2 Compiled Mar 27 2015
Operating system Android 4.4.2 API level 19 (Kernel: Linux 3.10.33
