It feels alot faster than my previous rom (Android 4.1.2, CNA 1.51 with touchwiz disabled with Franco milestone 6 kernel )

It's like it is more refined. I am Android 4.2 100% stock. I got all my music (around 3gb) and photo's/videos(around 3gb) on it with whatsapp, facebook (messenger) and some other apps installed.

So it's also not 'empty' :p

I'd say, just try it out! :)

Success. Downloaded factory images for Takju from Google, flashed only the system and boot image files. Then used method 2 and viola. My dad's GNexus is running smoother than ever with 4.2

For those how to want to have recovery, do this by gnex toolkit, it worked for me. I selected like I have 4.1.2 than I selected to flash recovery. After that I entered in recovery and flashed manually supersu.zip.

    if you are on a GSM Galaxy Nexus, it is time for you to enjoy some Android 4.2.

    from the thread [ROM][OTA][GSM][JB] Android 4.2 JOP40C: Rooted Busybox Odexed (11/13/12)

    Features

    • The latest Android OS, 4.2 Jellybean build JOP40C
    • Insecure boot.img (allows for elevated commands such as adb remount)
    • Rooted with the latest su binary and SuperSU app
    • Busybox 1.20.2 installed for increased functionality of root applications and terminal commands
    • Odexed version also available for purists

    Credits

    • Google - for developing Jellybean, the best version of Android yet!
    • Chainfire - for quickly updating SuperSU for Jellybean!
    • Goo.im - a great host and resource for developers and the Android community in general
    • Anyone I may have missed - thanks for all your contributions!

    Requirements

    • GSM Galaxy Nexus (GT-i9250) - your version does not matter (yakju, takju, etc)
    • ClockworkMod or TeamWin Recovery

    Screenshots

    Instructions

    1. If you are on any 4.0.x ROM, it is highly suggested you do a full factory reset (wipe data/cache in recovery) prior to flashing Jellybean!

    2. If you are upgrading from a 4.1.2 JB ROM you may be able to just wipe cache and dalvik cache.

    • Wipe accordingly as outlined above
    • Use your recovery to flash the ROM file
    • Do NOT flash any gapps - they are all included
    • Optionally, flash the baseband (radio) update if you'd like the newest one
    • Reboot - be patient, the initial boot may take a few minutes

    So alangrig made zip for takju and yakju update via CWM: preserves CWM and Root permission. Just don't forget in CWM after update before reboot choose fix SU. Works flawlessy

    Download link:
    takju (works great)
    yakju (looks like it has a bootloop bug)

    Make sure to make back up.
    I take no responsibilities for any outcome.
    This update works flawlessly on my Gnexus takju and version

    Make sure you follow the methods below.


    Method 1

    Note: the method 1 below will work just fine for JB — but you will need to re-flash CWM, and rename /system/etc/install-recovery.sh once you are booted.

    1) Download the correct update for your build on to your computer;
    2) Open the archive and delete the recovery folder; EDIT: Do NOT do this step if it you are using any Jelly Bean update, i.e., JRN84D or newer.
    3) Copy the file to /sdcard on your device;
    4) Reboot into CWM;
    5) Select “install zip from sdcard”;
    6) Select “choose zip from sdcard”;
    7) Select the update the you just copied to your device;
    8) Wait until it completes. Reboot. Done.

    Method 2 – Stock recovery installed, Unlocked bootloader
    1) Download the correct update for your build on to your computer;
    2) Copy the file to /sdcard on your device;
    3) Download CWM from here and place it on your computer in the same directory as your fastboot binary. For CDMA/LTE devices, use this version;
    4) Rename the CWM image to cwm.img
    5) Reboot into fastboot mode;
    6) Open a command prompt in the same directory;
    7) Type fastboot devices to make sure your device is recognized;
    8) Type fastboot boot cwm.img
    9) Select “install zip from sdcard”;
    10) Select “choose zip from sdcard”;
    11) Select the update the you just copied to your device;
    12) Wait until it completes. Reboot. Done.

    Method 3 – Stock recovery locked bl, no root

    1) Reboot your device into the stock recovery (i.e., the screen with the Android on its back with the “!”;
    2) Access the stock recovery menu by pressing power and volume up;
    3) Select “Apply update from ADB”;
    4) Download the correct update for your build and place it in the same directory as your ADB binary;
    5) Open a command prompt in the same directory as your ADB binary;
    6) Type adb devices to make sure that your device is recognized;
    7) Type adb sideload name-of-file.zip
    8) Reboot. Done.

    Please note: your device should also be running build JZO54K before trying to install the update manually.

    Click to collapse
    you need to be stock takju 4.1.2, you can be rooted but you will lose root and you will lose cwm as well but it will take you 5 mins to root and flash cwm so not that big of a deal

    hi, I have the yakjuux — Variant for Canada. Which procedure I should follow??
    Click to expand...
    Click to collapse

    You would first have to flash your phone to either to yakju or takju to receive the OTA. I would recommend flashing to takju so you get the OTA faster than the yakju version.

    1. Backup your phone (contacts, SMS, media, etc)

    2. Download the takju image for 4.2 (no need to get 4.1.2 and then get OTA. Better off flashing 4.2 from the get go) from here: https://dl.google.com/dl/android/aosp/takju-jop40c-factory-1a47c890.tgz

    3. Extract that into a directory. I suggest into one directory on your C: Drive for simplicity sake.

    4. Make sure your drivers are working properly - i.e. adb drivers.

    5. Download the adb and fastboot files from here; http://downloadandroidrom.com/file/GalaxyNexus/rooting/GalaxyNexusRootNew.zip

    6. Extract only the adb.exe, AdbWinApi.dll, AdbWinUsbApi.dll, and fastboot.exe into the directory where you saved your Takju 4.2 image from.

    7. When you have that all done. Turn your phone into the bootloader menu. By pressing Volume Up + Volume Down + Power Key until you see the word Bootloader.

    8. Open up command prompt and you need to change your directory path to where you have all these files installed.

    9. Type "fastboot devices" to see if it recognizes your phone in fastboot mode. You will see the serial # of your phone if successful. If not, a) drivers are not installed properly or b) all the adb and fastboot files are not in the same folder.

    10. Once its recognized, type in "fastboot oem unlock" to unlock your bootloader. This will wipe your phone completely, so backup your phone.

    Then follow these instructions (taken from another thread):

    1) Reboot by typing: fastboot reboot-bootloader
    2) Optional (NOT optional for n00bs) -- Flash the bootloader: fastboot flash bootloader bootloader-maguro-primela03.img (or whatever the name of the bootloader image that you downloaded).
    3) Reboot (not required if you did not do step 5): fastboot reboot-bootloader
    4) Optional (NOT optional for n00bs) -- Flash the radio: fastboot flash radio radio-maguro-i9250xxla02.img (or whatever the name is of the radio image that you downloaded).
    5) Reboot (not required if you did not do step 7): fastboot reboot-bootloader
    6) Flash the system partition: fastboot flash system system.img
    7) Flash the data partition: fastboot flash userdata userdata.img
    8) Flash the kernel/ramdisk: fastboot flash boot boot.img
    9) Optional (NOT optional for n00bs) -- Flash the recovery partition: fastboot flash recovery recovery.img
    10) Erase the cache partition: fastboot erase cache
    11) Reboot: fastboot reboot
    12) Done! The first boot will likely take quite a bit longer than you are used to, as Android builds the Dalvik cache.

    If you still need help, I could help you out provided you live in the Toronto/York Region/GTA areas heh.

    Cheers
