I wish I would have taken a pic but I will try my best to describe it. once the error occurs it prompts you to check the cable and to put the car in off position. I just pulled the key off. I unplugged the cobb and started over. The first time it just gave me a error was when it tried to read my tune. it failed, after that it tried to rebuild my flash using the recovery mode on the cobb menu and it would fail after 2%. I did try something different the 2nd time and that was remove all the tunes from cobb so it was like it came from the box just updated for 07. then I tried the recovery again or it tried to rebuild my stock map. that time it went to 90% or so, once the error popped up I took the key out and put it back into the on postion and started again. once it finished I unplugged everything reloaded the tunes and tried to load the 91 tune. that took about 10min. I notice when it first started the recovery it took a while for it to increment in percentage. once it was out of recovery it was loading a whole lot faster. I know what it feels like. I almost smashed the cobb I was getting so frustrated...
I hope this helps. I honestly was just trying everything I could think of at the time. I was so pissed I was going to leave my car over the weekend I was not thinking straight at the time or else I would have taken video to post, but once installed and I was over my anger I took video of the DYNO runs...

However, I'm interested to learn that you were eventually able to succeed in getting past 3%...did you do anything differently the last time around? Also, could you describe the recovery mode that you entered? I haven't seen a prompt for that or an option in the menu. I've tried to install about 15 times and have consistently had the exact same outcome.
