Galaxy S2, help required roms etc

[willij5]

Hi guys

This is my first post, I am trying to follow this guide:

http://androidforums.com/galaxy-s2-...7-12-dummies-guide-installation-settings.html

When I try to download the Tar and Zip files to my computer, they keep coming out as a zImage file.

I have managed to install the gingerbread 2.3.6 firmware on my phone the other day via Odin.

But something seems to have changed PC side.

Is there a programme I should have on my pc so when I download the tar files, I can save them as tar files?

Thanks in advance
