Moving to Ebon Hawk's Machine Room as this is an XBox question...
You don't edit any changes.ini files... those files are instructions to tell the Patcher.exe where to put what files and what to edit where. Also mods with models tend to not work on the xbox. See this thread. (

Lastly my mods were made for the PC version, and since I have no modded XBox, as such I can offer no real assistance in this endeavour.
Suffice it to say the patcher installer is meant to be used on the PC version of the game. The files can't be simply copied into override. Sorry
