Nevermind. In case someone was wondering, yes, it worked.
I'm a bit confused...seems to be my normal state of mind....I'm rooted and unlocked on my xt926. I did a temp unroot using Voodoo and accepted the 9.20.1 upgrade and then restored root. All went well, I think....except my baseband version is ...64.09P. I thought I should have received an updated baseband with the system upgrade. Am I missing something?
