Hi, I'm a little confused. Here in Brazil our Galaxy Nexus is called Galaxy X. It's basically the same phone, but we haven't recieved 4.0.4 update yet. We are stuck on 4.0.2.
How an I flash the yakju firmware on my device? I searched for tutorials here on XDA but I couldn't find anything conclusive.

Default Update Galaxy Nexus

Thanks for the great guide.

I recently got my Phone from the US i.e. Galaxy Nexus. It shows the Android version as 4.0.1. How can i update it to Jelly bean or be eligible for the update?

Best.

WHAT IS ALL THIS TALK ABOUT FIRMWARE VARIATIONS?
With every Nexus phone, there has been a "master" firmware, plus other localized firmware variants for certain regions or carriers. Sometimes these variants will contain language packs, additional ringtones, slightly different baseband (radio) firmware to make it work better for a particular carrier's network, etc.

In the case of the Nexus S, Google maintained the master and all the local variants. On the Nexus One and the Xoom, Google only maintained the master firmware while carriers and/or OEMs maintained the local variants. In the case of the Galaxy Nexus, there are three Google-maintained master firmware variants, and many more Samsung-maintained local variants.

WHAT ARE THE DIFFERENT VARIANTS AND WHAT DO THEY MEAN?
Below is a definitive list of all known firmware variants for the Galaxy Nexus, and what models they shipped on:

GSM/HSPA+ Models
  • takju - USA region- and carrier-independent firmware released on models sold in the USA through the Google Play Store
  • yakju - International region- and carrier-independent firmware released on models sold throughout western Europe.
  • yakjudv - Variant for Australia
  • yakjujp - Variant for the Middle East
  • yakjukr - Variant for South Korea
  • yakjusc - Variant for Japan
  • yakjuux - Variant for Canada
  • yakjuxe - Variant for Russia and the former Eastern Bloc
  • yakjuxw - Variant for certain carriers in Western Europe
  • yakjuzs - Variant for China and Hong Kong

CDMA/LTE Models
  • mysid - Variant for Verizon in the USA
  • mysidspr - Variant for Sprint in the USA

HOW CAN I TELL WHICH FIRMWARE I HAVE ON MY DEVICE
Using any file manager app, go into your /system folder and open the file called "build.prop". Find the line that starts with ro.product.name. Whatever comes after the equals sign (=), that's the firmware you have.

WHICH FIRMWARE IS UPDATED BY GOOGLE AS OPPOSED TO SAMSUNG?
Google updates the following firmware variants:
  • takju
  • yakju
  • mysid

Every other variant is updated and maintained by Samsung.

SO YOU'RE TELLING ME THAT THE SPRINT GALAXY NEXUS GETS UPDATES FROM SAMSUNG AND NOT GOOGLE?!?!
Yep.

WHY DOES IT MATTER WHERE MY UPDATES COME FROM ANYWAY?
For all practical purposes, it probably doesn't. However, this becomes an issue if you want timely updates. When Google drops a new OTA update for the Galaxy Nexus, they always announce it through official Android channels. When they announce a Galaxy Nexus OTA, they are only referring to devices running the firmware that they control.

This means that if you have a Sprint Galaxy Nexus, or a GSM model running one of the yakju(xx) firmware variants, your device is not included in the OTA rollout from Google. Your update will instead come from Samsung sometime in the future after they make whatever region- and/or carrier-specific changes they need to make for the firmware.

I HAVE A VERIZON GALAXY NEXUS. THE FIRMWARE IS UPDATED BY GOOGLE SO WHY DOES IT ALWAYS TAKE LONGER FOR UPDATES TO HIT MY DEVICE THAN THE GSM/HSPA+ DEVICE
Even though Google maintains and updates the mysid firmware on the Verizon Galaxy Nexus, Verizon must test and approve the updates before Google is allowed to roll them out. This introduces delays, sometimes lengthy ones. For instance, Android 4.0.4 began rolling out to the Galaxy Nexus GSM model on March 28, 2012. The Verizon device didn't get the update until two months later, on May 31, 2012 due to testing delays. That's not to say that all future OTAs will occur on a two month delay, but it's best to be prepared for the worst.

WHAT'S THIS I'VE HEARD ABOUT BEING ABLE TO FLASH YAKJU FIRMWARE ON A DEVICE RUNNING YAKJU(XX)? IF I DO THIS, WILL MY UPDATES COME FROM GOOGLE?
You can flash yakju firmware onto any Galaxy Nexus GSM device that's running a yakju(xx) variant. This is outside the scope of this guide, but instructions can be found here on XDA with a little searching. Once you're up and running on yakju, your updates will come from Google rather than Samsung.

DOES THE SAME THING GO FOR CDMA? COULD I FLASH THE VERIZON MYSID FIRMWARE TO MY SPRINT MODEL AND GET UPDATES FROM GOOGLE?
No, No, No and NO! If you tried this, you'd probably risk hard bricking your phone, and even if it did boot, you'd have no mobile data and probably wouldn't be able to make calls either.

WHAT IF I HAVE FIRMWARE-RELATED QUESTIONS THAT AREN'T ADDRESSED IN THIS GUIDE?
Post them here and I'm sure someone can answer it for you.
- I have question: If i flash yakju firmware on yakjuxx model, my GN change to yakju mode or not? Thank you for support.

Default Thanks in advance!

Hello there,

Sorry to bother you all; first post!

I saw the noob video, so I'll be quick.

I've figured out what version of Nexus I have finally through your guide (yakjuux for Canada), but what I'm trying to figure out is if my Canadian Nexus is a GSM, VZW....or the other one I can't remember.

If you could help me out with that, I'm sure I'll be able to find the rest of the info on my own.

Thanks so much in advance!

EDIT: My phone is under Virgin Mobile's network, if this helps any.

Well, let's think about this for a minute: Sprint and Verizon do not operate in Canada, so... if you bought a Canadian phone, what version do you think it has to be?
