If you are still flashing the GB files try to grab a screen shot with the errors. This might help some others to know what to expect as normal errors. Just click the window and expand it. Hold down the alt key and do your screen shot. On my dell laptop I have to press the function key and F11. Then open paint or picture manager or something similar. Click paste, save and post here. I should have thought of that when I did the jump last night. The webtop part takes the longest, it's the biggest image.
That's not a bad idea. Having run into so many issues, I specifically went through the batch file to look for errors. The only ones I recall seeing are the ones that say "INFOPreflash validation failure". I think I had 2 or 3, but I can't be sure. I just don't remember seeing any other types of errors when it finally worked.
