What if Firmware doesn't match CDA?

I'm trying to flash a w380 CID53, in the combo on the right of the [continue] button i read Europe_1 (and only Europe_2 option is available).
As I need to flash Europe_5 firmware (which is available), I'm asking if there is any problem doing this, even if the two Europe versions dont match.

what are the two fields about? the second one is the firmware, but the first one?

thanks:confused:

the first one is just the location of the FTP server,you can choose the nearest FTP server to get a faster downloading speed.
