Okay much better. First off, you're going to have use use the utility again and use option 1 to restore to stock ics. The reason it's failing is because there usb probably still something installed that is blocking the installation.
Once you do that, re root your phone and install voodoo again and do this:
Backup root
Temp unroot
Restore roof
Temp unroot
Restore root
(make sure to do it twice just to be safe)
Place the zip on your sd card, yes the file you have is right. Moto names them weird for some reason. Just like the . 181 update said .173 in the file name.
Boot into recovery, and install zip from sd card.
Let it do its thing.
After booting if you can't get root back with voodoo then you will have to download another tool that Matt made that recovers it, but you have to make sure it was backed up with voodoo before you flash jb or you can't recover.
