O2 Mini WWE to Imate Jame Portugues ROM How to?

[jrivero]

I Have and 02 Mini with the EnglishROM 1.11 WWE which I would like to upgrade to a portuguese ROM.

The only portuguese ROM i have found is the

JAM_10605_169_10500_ship

When trying to upgrade I got the country error and then after doing the MaUpgradeUt.exe I got the
"ERROR 150: ROM UPGRADE UTILITY ERROR
This ROM Upgrade Utility does not design [sic.] for you device.
Please get proper ROM Utility Upgrade and try again!"

How should I proceed in order to achive the upgrade and Language Change?
Can any one lead me to the correct Portugues ROM? Is is poosible to go from the O2 ROM to the I mate jam ROM?

Thanks

I forgot to mention that I am running Vista with the Windws Mobile Device Center. Will that impact the upgrade. Should the upgrade only be done under XP and Activesynch?

I also forgot to mention that the only reason that I am trying to download to the Jam Portuguese ROM is that when I downloaded the Magician Portuguese ROM in the Wiki {http://wiki.xda-developers.com/index.php?pagename=HTC_Magician} the file would not unpack and or work. Whenever I clicked it nothing would happen. When I tried to extrat files with the win rar app I get the folowing message "The archive is in unknown format or damaged"

Help!! thanks

I finally managed to upgrade my ROM to a different Langauge. I was previously unable to do it since I was working thrugh windows Vista once I moved to an XP computer it worked on the first try.
