[Download] Android 4.2 (JOP40C) for the GSM Galaxy Nexus

---

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

Downloads

Primary Link (Goo.im)

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

official takju - aosp | OTA


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.

Hey guys, Does it matter if were on Takju or Yakju? And I have TWRP installed. Will I have to reflash that after I am finished or will this take away Root completely?

Thanks!

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

One more question!
