I have just download CyanogenMod Installer from Google Play Store and still have it in my now Android KitKat-running Nexus 4. I intended to install CyanogenMod 10.1.3 which is based on Android Jelly Bean 4.2.2, on my nexus 4. I have not done so. --- I also have the intention to install the stock Android Jelly Bean 4.3 on the same nexus 4; downgrading from Android KitKat 4.4. I found that Android KitKat on Nexus 4 (and Nexus 5) now redirect tethering network traffic to the carrier login page, specifically T-Mobile USA. Strangely, I had no problems using the built-in tethering (Nexus 4 - Andorid KitKat combo) with AT&T network.
