Yakju update from JRN84D to JRO03C without data wipe

This is a tutorial about updating from Koush's JRN84D repack/jb-takju.zip to Google's JRO03C OTA for yakju users.
Although this kind of method isn't recommended as wiping is important when upgrading, it might help n00bs or guys who hate using TB (like me) a lot.
Prepare adb, IMM76I factory image and the OTA file (Galaxy Nexus Toolkit can be also used instead of adb).
Backup your phone with Nandroid.
Open the factory image with 7-zip, open the tar file inside, navigate to yakju-imm76i and open image-yakju-imm76i.zip.
Extract the boot.img and system.img
Flash the boot.img and system.img with adb/Galaxy Nexus Toolkit.
Go to Recovery Mode and push the OTA file to /sdcard/.
Flash the OTA file.
Reboot you phone. If your see something like a bootloop, pull out the battery and boot again.
After boot into system, you'll see Setup Wizard. Set language, GPS and personal info.
Finished. Welcome to 4.1.1!

You don't need to do all that... just boot a temporary CWM and flash the 4.1.1 update.zip .

Yup. This is what I did and haven't had any issues yet.

Me 2.
Although I forgot to flash the Superuser zip afterwards and I had to use the toolkit to root again.
The only "issue" I have is that Google ears and other apps freeze themselves after a reboot.
I have to use titanium backup to defrost them after a reboot.

Fastboot boot cmw_recovery.img or simply use the toolkit that does that for you.
You need an unlocked bootloader though.

Is the 4.1.1 update.zip the OTA file that OP linked to? (f946a4120eb1.signed-yakju-JRO03C-from-IMM76I.f946a412.zip)

This will allow you to boot to cwm recovery without writing over stock recovery? Could I use this to install su and gain root while never overwriting the stock recovery?

How to get in cwm if I just have odin mode?

Hi, I ask that because the "+"volume buttom of my phone was broken, so that my phone can only boot into the Odin mode/download mode.
Also, my phone can't boot normally becase I flash something wrong so it got a bootloop, so how can I get in the cwm if I just have the Odin mode/download mode? Thx!!

You can use the galaxy nexus toolkit to boot it into cwm recovery.

No he cannot.
@OP: There is no way to get to recovery (that I know of) without either a) being able to boot into Android, or b) having access to the bootloader.
EDIT: You can try an Odin flash to flash all the stock images, and then go from there.

You can try removing the userdata image from the odin .tar. Assuming your bootloader is unlocked, flashing the other images should leave you with your data intact. Note that you will need to wipe data from within CWM if you flash a version of Android (without the userdata image) via Odin that is different than what you are currently running, otherwise it will not boot. But at least you will have whatever is on /sdcard.
No guarantees that it will not wipe /sdcard (as I have never tried it), but based on what I know, it shouldn't.

Yes, Odin will wipe everything. I have the sane issue currently with my volume down key, but luckily no software issues.
I'm wondering if this busted volume key thing is a common occurrence, or if you and I just got lemons. Gonna have mine looked at tomorrow.

It should NOT wipe everything IFF: 1) your bootloader is already unlocked, AND 2) you remove the userdata image from the .tar.

So now I download the stock images from google and flash with Odin MODE?

No, the images need to be packed into a .tar so that odin can flash them. What version of Android are you running?
Chainfire has IMM76D images here, and there are some JRO03C images as well somewhere. In order for you to be able to boot without wiping, you need to flash the same version of Android that you are currently on, or add CWM to the package (renamed to recovery.img) so that you can wipe data. Otherwise, you will not be able to boot. Follow the instructions carefully -- make sure you do not have re-partition checked.

You need to make a .tar using the boot and system images from JRO03C. I don't think there is one already pre-made.
1) Download the JRO03C factory image corresponding to the build that you are running (yakju or takju), and extract the system.img and boot.img files.
2) Download CWM 5.5.0.2 and rename it to recovery.img.
You should now have 3 images: system.img, boot.img, and recovery.img. Next is to package them for use with odin. This needs to be done either 1) on a linux box, or 2) on a Windows PC running cywin, or 3) on your phone (I believe).
Code:
tar -H ustar -c system.img boot.img recovery.img > ODIN_JRO03C.tar
md5sum -t ODIN_JRO03C.tar >> ODIN_JRO03C.tar
mv ODIN_JRO03C.tar ODIN_JRO03C.tar.md5
Now you should have one file ODIN_JRO03C.tar.md5 which you can load up and flash with Odin. Follow the instructions in Chainfire's thread that I linked to earlier.
Usual disclaimer: I'm not responsible if you mess up your device using the info here...

I can't get to recovery mode?

I can get to downloading mode but recovery mode, I get stuck on an Android logo lying down with a red exclamation mark. I had failed to convert to yakju through fast boot, I got stuck to Google logo back then and also no recovery mode. Then I tried the toolkit and everything is working smoothly except for the recovery mode. What should I do? How can I get that working?
Sent from my Galaxy Nexus using xda app-developers app

What I would do is use the tool kit in these forms to install the recovery it seems like you have lost your recovery , that's what happens when you lose your recovery you get the Android guy lying down. When using the toolkit make sure you follow the instructions exactly! If you don't it will default and you will lose recovery.
---------- Post added at 07:12 AM ---------- Previous post was at 07:10 AM ----------
Also just a little bit of information in the toolkit you have an option to rename your stock recovery if you don't do this and use this option it will default in rewrite over your recovery the stock recovery .

Thanks!
Is there a risk of losing any data while using the toolkit to install stock recovery?
About renaming, I don't really understand. Do I need to rename the stock recovery I'm going to install? If I don't use the rename option, what do I lose? Could you please explain this part a bit. Thanks again!
Sent from my Galaxy Nexus using xda app-developers app

Download the G nex tool kit I believe it's version 7.8 it explains everything just do some reading and what I mean about the recovery is the stock recovery has to be renamed for you to install a recovery or it will not work if you read the gnex toolkit it explains the whole thing. No you do not have to rename the recovery you're installing. The option to rename the stock recovery that comes with your phone is in gnex toolkit. I think it's option 3 maybe? Trust me read the notes that come in the toolkit is very easy!

You haven't lost recovery, that's just stock recovery, you need to remove the file that puts it back on every reboot (search or there's an option in the toolkit if you must) then fast boot flash Cwm or twrp and you are set

I have tried both "Installing Stock Recover" and "Renaming" and both got me to the same lying down Android with the red exclamation mark. What else should I try?

You need to do renaming then install twrp or Cwm recovery, stock recovery is useless to you, that's what the Android on its back is.

Why stock is useless to me? I don't want CWM, I want to have stock recovery, is there a way?

You can't flash anything in stock other than factory reset and allow the phone to self install OTAs..

I understand and I want to keep the stock recovery and to get it to work to be able to install OTA directly. How do I get it to work? I have to install CWM then I'd be able to switch back to stock? I'm lost

Never buy a phone off craigslist without powering it on and checking it out. There's no telling what could be wrong with it.

Does it boot to recovery? If so, clean wipe and flash another ROM. Maybe the installed ROM in /system is bad, so a factory reset (which I believe only wipes /data and /cache, not /system) isn't enough. If no custom recovery is installed, try flashing one from fastboot. If that doesn't work, contact the seller.

Craigslist is probably the sketchiest way to purchase phones from other people. Use Swappa!

Assuming you have all required files. Change whatever file name and extensions you need.

You need to download the Verizon Gnex Images (Toro) from HERE
EDIT: Unless you are on Sprint or GSM, download those images.
After downloading, extract the zip file and then dig through until you see another zip file. That's going to be the stock factory system image with other important image files. Extract that zip file to the platform-tools folder in the Android SDK folder.
Next you're going to need to use those commands mentioned above to fastboot them.

Simple, wait until it's actually announced and ready to download for your device. When 4.4 is announced, it may or may not be ready that very same day, so sit tight. You'll see enough news about it to know when it's ready.

I'll get an ota message even if I'm on a custom rom? And I can install that without any problems?

No, when it's release and ready to download just go back to the stock rom, then there you'll get the OTA.
I personally will wait to download the img, restore the Nexus to 4.4 and just to try Kit Kat, then I'll just flash back to AICP, I'll wait then for 4.4 to get incorporated into custom ROMs.

I'm on stock ROM and stock recovery, but rooted + custom Kernel, does anyone know if I can receive the OTA?

You can get it from the stock images, just extract the boot.img and flash that via bootloader using fastboot. Same goes for stock recovery.
