I had the opposite prob. Stuck in 1X after rooting and the metro-dawgs couldn't help me. ninjasinabag referred me here, and while whiterabbit didn't help me find the SPC, I was able to get it from meidconverter.net.
from there it was a matter of choosing the LTE/CDMAevdo auto option and I was back in bidness again.
so again, mucous garcias mi amigo
