I have been pulling my hair out for 2 days trying to figure this out. I've been trying to install 2.1 and when I get to the part of extracting the Droid Helper.apk to the root, that is where I get nothing. Do I extract the apk and then drag it into the root? If so, then I have done this and when I go to ASTRO it does not show up as something to install. It will ask to extract and then when thats done I have nothing!! I am a noob but I know how to follow directions. Need some serious help!
