PS3 Mods menú Call of duty

[xRoWnS]

Hello, I am quite new to the CFW topic. I have fully configured the Dex console. But I want to try a couple of menu mods in Call of Duty games but so far no "Good" mod has worked for me and I'm on DEX, what could be wrong? the eboot? Does it have to be from the same region? I put the eboot in the "GAMES" folder and the sprx in "TMP" but either the screen remains black or the menu is not a solution? Thank you very much for the help You are always helping Happy new year
