DS-2CD2132F-IS multilanguage from v5.2.3 to v5.2.5

[tul9033]

I have several of the DS-2CD2132F-IS cameras (from China with English language) with mixed firmware. Half are 5.2.3 and the other are 5.2.5. Not a big deal normally, but there are several screens that are different between the 2.
I've looked at the stickies and I can't find anything about safely upgrading v5.2.3 to v5.2.5
Any tips, pointers, or links are much appreciated.

I'm not sure that is a good enough reason to risk bricking them.

But they're not my cameras... so meh.
