I was on JOP40D (4.2.1) Stock, rooted, with CWM 18.104.22.168. I downloaded this OTA file http://android.clients.google.com/pa...D.6ece895e.zip
from the link in the other 4.2.2 thread (http://forum.xda-developers.com/show....php?t=2144330
I booted into CWM, and flashed the downloaded ZIP file as normal
When I told CWM to reboot, CWM warned me the update would flash stock Recovery and do I want to STOP this from happening and I said YES.
It then said I had lost root, and do I want to restore root, and I said YES.
It then booted into Android and continued with the upgrade.
I now have 4.2.2 stock installed (JDQ39), and still have root and custom recovery, and an unlocked bootloader.
From what I have read, if you 'sideload' the update using ADB, or do a normal OTA update, you will lose root and custom recovery. However, using the steps above will keep root and recovery for you
