[Q] Error while installing Mango

[tbvnz]

After step 6 while trying to install Mango I recieve error code 801812c1. I've tried to find what it is and tried to use the Fixit wizard, it tells me everything is fine. but I continue to get the error code. Any ideas?

For the NoDo install, I was getting an error until I power cycled the phone, including removing/replacing the battery. Not sure it will work but worth a shot.
