After some more reading found the reason I was receiving the error message when attempting to install the OTA was that I removed some of the original apps after I rooted under ME7. So found out that you can flash the new MI1 build by following instructions found at XDA, [GUIDE] No-Wipe Factory Images (Restore from any soft-brick without wiping data) - xda-developers. I successfully followed these instructions this morning now just have to perform the new Root De La Vega instructions to get root back. Not really noticing any differences in performance, a few new apps, but was more curious if the new update would turn on AWS support. Doesn't appear to make any difference in my region. Good luck!
