Hi Blackdog7 you wrote
"I have the same message always. How did you format your card to a successful android install?
I tried format with flashformat, format with XP and win7 too. I tried the cab and the zip version too. I have a 256 MB Sandisc card. Is the capacity enough?"
I don't think that 256 MB is enough, go for a 2 or even 8gb they are so cheap on amazon. In windows XP just right click on the removable drive and choose format, don't do a quick format. Then follow the instructions to install android, preferably the cab file on to the card.
Hope this helps.
