I did not keep root because I was not paying attention and so lost root. I thought I was canceling the update but since I was half asleep and didn't have my glasses on I apparently hit to install instead. So now I'm wondering how to get back root - or maybe just do a full factor data reset and start from scratch. Any info on my issue appreciated.

I believe to keep root you have to download Voodoo root keeper, or something like that. I wish I had done thing ahead of time!

 

I kept root. I used Voodoo OTA. Protected root, then Temp Un-Root. Accepted the OTA and after the reboot went to Voodoo and Re-rooted. Tested against Root Checker and various apps that use root and all is working.

 

Voodoo as well. I also unlocked the BL though

 

Far as I can tell this method has worked for me.
