I got the problem that my Nexus sometimes wants to update to 4.2.1 although the system update menu says the newest version is installed (4.2).

When I let the update do what it wants and it reboots, it fails at the recovery system with "apply patch check something".

Only thing I've done to my Nexus so far is rooting it.

The version check from the System Update menu, seems a little bit "off", whether that's a minor bug, not sure...4.2.1 is fairly recent, now that 4.2.2 is out - FYI! The apply patch check something is down to either boot-loader is locked, or that there is not enough space... – t0mm13b Feb 13 '13 at 21:08

I don't think a rooted Nexus 4 will be able to update automatically. So you might have to turn auto update off. Rooting will void its warranty.

But not to worry, rooting is good. Some how you can flash an updated version of stock ROM manually to your device.

Rooting does not void the warranty in the EU :) – Izzy Feb 13 '13 at 21:00
I saw stock ROMs available for the Nexus 7 but I cannot find them for the Nexus 4. – Someguy Feb 13 '13 at 21:06

@Izzy, I am sorry I didn't know that. :) – The Dark Knight Feb 13 '13 at 21:09
That's why I mentioned it -- no need to be sorry, just need to remember ;) – Izzy Feb 13 '13 at 21:16

The OTA update won't work with root. You can manually flash a ROM to your device. You can get stock (factory) ROMs from Google, Nexus 4 is about 1/3rd down the page. You can also go to XDA forums and get a custom ROM, main forum page for Nexus 4.

The other way would be to use Wugfresh Toolkit for Nexus to relock/unroot device, to be able to get OTAs.
