According to the Android Police site, Google have started rolling out JB 4.20.

More information here.

If rooted and you're feeling brave (!), download is here.

The DEVELOPER OPTIONS menu seems to have been removed under JB 4.2 !!

Not sure how you enable USB DEBUGGING now.

I lost root when I updated, but VOODOO ROOT KEEPER added it back.

OK, seems it's fairly easy to enable DEVELOPER OPTIONS under JB 4.2:

1. As usual, goto Settings -> About Phone.

2. Goto “Build Number” at the end of the Scroll list.

3. Tap on “Build Number” for 7 times. While typing at the third times, you should see prompt message to indicate you that 4 more taps to go to developer options.

4. Continue 4 more taps.

5. You are now done and go back to the Setting page.

6. You should see Developer Option appear on your setting list now.

With Developer Option appeared, you can enable the USB debugging mode for future flashing and development work.

Thanks to theandroidrom.com for this.

Are you rooted ??

If so, you only need to download the ZIP posted above and flash it via recovery. I use TWRP.

I used WUGFRESH's Nexus Root Toolkit to root mine.

If you are not rooted, then you need to wait for the OTA update.

Try using ROM Manager instead. The options at the very top let you install the latest CWM recovery and verify. Of you have any more questions or issues, let me know.

Yes, I was able to enable developer options. Now I need to restore root. I lost it, and OTA Rootkeeper isn't seeing Super SU (the only box checked is '/system supports root protection.' Super SU can't update successfully..

Did you have similar issues restoring root? How did you get it back?

Open Super SU and update the binaries and OTA Rootkeeper should see the Super SU app.

I get an 'Installation failed' message when trying to update the binaries.
