Getting OTA update once phone is rooted My nexus 4 is rooted with a team win recovery. 

In the past week I've been asked three times to update to lollipop, downloaded the update but all three times the phone rebooted and the custom teammwin recovery failed to install the update... 

I'm afraid having rooted my nexus makes it ineligible to official updates. Could you confirm it?

Do I need to come back to stock rom &amp; recovery, then install OTA update and root it again (seems like a long process and possible memory wipe?)

Thanks for your answers!
You can also just reinstall the official recovery image by downloading the same factory image as currently running and extracting the recovery.img that's contained within.

Then you could reinstall the official recovery image by booting into fastboot mode and doing an:

    fastboot flash recovery recovery.img


This should give you back a working OTA mechanism. However note that you need to re-root after the update because this will undo the rooting procedure.
