HELP! I can't go back. I flashed the May 06 update just fine. I flashed this beta just fine, but when I try to flash back to the May 06, it starts the progress meter, slams it immediately to 100% and says 'there were problems with the software upgrade ... Invalid Image ... Code 3' with a link to the website, where I can't find anything about code 3. This is the same May 06 image that flashed just fine before -- and just to make sure, I downloaded another copy of it before writing this. Any ideas ????
