WHY would you like to upgrade ? Because “people” say so ?! I still have a spare X96 with 1GB Ram and Kodi 16.1 and can still watch 720P series and movies witn NO buffering. Well, nó build so nó garbage and ónly the 2 addons that I use and a fast VDSL internet connection. So…..YOUR Box seems allright ! Factory reset, delete what you never are going to use, install the latest Kodi and ONLY the Repo(s) and addons that tou REALY NEED on a daily basis. Have fun.
