Do you have S-OFF?

No, someone told me that would work with S-ON
I wanted to restore to Stock and upgrade to the new Hboot and everything (still using .57)
But when I use the stock updater it just says USB connection error 170

You need to have S-OFF to write to recovery partition.

You can try installing the AT&T 2.2.2 update using this alternative method explained here: http://forum.xda-developers.com/showpost.php?p=18541475&postcount=145
