Well it didn't hang. It threw an error but left me without a /system because it had already erased it. Me being stupid I rebooted which then didn't allow me to access the bootmenu.
I did the same thing and the Chinese fastboot files worked for me...
I fixed my problem using the fastboot from the successful downgrade thread in the general. i just wanted to thank you for all your help
