Download Stock x8 Rom/or Costum ROm [i see alot of Costum Rom look like Stock x8 Rom] and grab all what you want. launcher,music apk. etc. in /system/app folder.
P/s : any question post in Q/A section.
You go try a couple of the "prepackaged" ROMS that look like an updated UI for the X8 such as SEMC Debrand Xperience and its predecessor Achotjan SEMC Debrand. These use custom ROMS, (and kernel) and have a revamped UI. I am running SEMC Debrand Xperience and love it!
