Help Samsung Galaxy 550 update problem

[dobledosis]

I bought this phone (GT-I5500L) that came with Android 2.1 i manually updated to 2.2 with "OdinMultiDownloader v4.28"
Europa "http://www.multiupload.com/8RHO5C274Y" (I dnt know what is this for).
Froyo rom 2.2 "http://www.multiupload.com/UPKSVCZ7KU"

Now i have a problem. I cant use the external volume keys to set the volume when im lisening to music ot whatever and the phone is locked.

I think that this froyo is not the oficial samsung update, when i had the 2.1 Kies said that my phone was up to date (2 days ago).
Where can i get the official rom from samsung? Im from Argentina. Thanks!!

Samsung are said to be rolling out official Froyo 2.2 update via their Kies software during March. So keep plugging your phone into Kies and maybe you will be lucky!
