There's a program named "7zip" that might help. It's free, try downloading and installing 7zip on Windows. ".gz" is a compression format, I believe, like .zip. Just "removing" the file extension won't help, I'm afraid. I think you need to decompress the .gz file. Then, you'll have your shiny SBF.is this a dumb question? the file name ends with ".gz" and im assuming i just removed that and use RSDLite?
so, if I am on a old apex rom....and want to upgrade to GB....can i just sbf using this file or do i need to sbf to Froyo, then ota upgrade from there?
Thanks!!
