This wont work i have a depatch Thread here on mpgh back in july.
and the latest update depatch will work any were below will disconnect you from the game this also counts for putting in the newest map patch.
the reason this wont work is because the servers contain a specific area of were the items will be placed if you change things like installing the newest map from us the EU server wont recognize that and it will disconect. further on depatching has been usefull tomee in grayhammer but the locations of the deathzone's aren't set in the maps them selves no the coördinates of the deathzone's are located at the Nexon server + i had graywalls removed because those are ingame effects. im still trying to openup the .DAT files so i can edit the World Maps and i will delete all black walls (black walls only block you from shooting out of the walls and simply walking out of the walls).
here is your information about depatching or prepatching CAEU.
