Everything is stored in your /system/build.prop file.

Root, no. CWM will prevent the update from installing over-the-air, but it does not prevent you from downloading the update and installing it yourself (as per this thread). And besides, the update will likely be posted in that thread before you receive it OTA.

it's work

wow, it's works, big thanks

Jelly Bean yakjuxw to jelly bean yakju?

Hi,

I am currently on Jelly Bean yakjuxw 4.1.1

Is it possible to use these steps to convert to yakju 4.1.1?

Thanks,
[Samsung Galaxy Nexus] pafaisal:
Yes you can..This is mentioned in the beginning of this thread...

"You can easily convert ANY GSM/HSPA (i.e., maguro) device to stock yakju (or takju) from any non-yakju build (yakjuxw, yakjuxs, yakjuux, yakjusc, yakjuzs, yakjudv, yakjukr, yakjujp, yakjuxe, etc.).
[Samsung Galaxy Nexus] fakekullu:
Efrent, thank you so much for the detailed work-through.

Ok, I'm facing some issues on the "Open CMD and enter fastboot devies". The CMD states that it doesn't recognise fastboot as a command etc. I'm also getting a fastboot command read error...tried different cables, USB ports, but nothing :(
[Samsung Galaxy Nexus] thephantom:
The platform tools need to be in the directory where you're typing the command. From cmd, you need to navigate to the folder where the tools are. Example is if you saved it in your desktop in a folder named Nexus, from the cmd window you need to input cd desktop then cd nexus so you are in the folder.
[Samsung Galaxy Nexus] fakekullu:
Done! That's what I was missing.

Thank you so much! :D
[Samsung Galaxy Nexus] peikojose:
Hi,

I'm coming from a HTC Desire, so I'm a noob when it comes to Galaxy Nexus. But not that noob with Android.

I've rooted, unlocked and installed Clockworkmod Recovery v6.0.1.5 touch using GALAXY NEXUS TOOLKIT V9.1.0.

Everything works fine, like it did with my Desire.

My Nexus is maguro/4.1.1/yakjuxw.

Right know I don't care about installing 4.1.2...

BUT I want to be ready when 4.2 is launched (Maybe this week), so I need to know what do to when I get the "4.2.zip" from here.

Do I have just to flash it using CWM Recovery as usual? I did think that is what I had to do...! But I have read that version of CWM (Touch) doesn't work well...! I don't understand that because I have tested it and it seems to work fine. Reading some guide the poster says something like "If you use CMW Touch don't even ask"

What can I do with the .tar files directly from google? Can I use them as .zip and flash them using CWM?

Will they reeplace my recovery?

Right know if I flash a Yajku ROM, will the phone be Yajku then? (I understand that anyway I won't get OTA updated because the custom recovery).

Please help.
[Samsung Galaxy Nexus] efrant:
First of all, your 4.1.1 build is yakjuxw, and yakjuxw has not even been update to 4.1.2 yet, so it won't get the "4.2.zip" any time soon.

The "4.2.zip" that will arrive soon will be for yakju and takju only. You will not be able to apply that zip to upgrade you yakjuxw 4.1.1 to 4.2. If you want to use that zip, you will need to flash a yakju or takju build.

Second, if you are running yakju or takju, you will be able to use a custom recovery to flash the "4.2.zip" just fine assuming you download it from here first and save it to your /sdcard. It will not flash if you download it via the OTA notification if you have a custom recovery.

If you extract the images from within, there is a stock recovery in there, but it will be for yakju or takju only.

Yes, if you flash a yakju ROM, you will have a yakju ROM... :)
[Samsung Galaxy Nexus] peikojose:
Thanks for your reply.

I understand that because my build is yakjuxw I won't get the Android 4.2 update soon, but that is my point. If I just flash the Android4.2Yakju.zip as soon as it is posted here using CWM, will it work?

Will that change my build from yakjuxw to yakju? (Knowing that it won't update OTA because of the custom recovery).

Sorry if I don't understand.
[Samsung Galaxy Nexus] efrant:
No. It will fail in all cases. A yakju update will only work on a yakju ROM. A yakjuxw update will only work on a yakjuxw ROM.

No, it won't change your build, because if you try to flash the zip it will fail.
[Samsung Galaxy Nexus] peikojose:
So what are my options?

Looks like with CWM 6.0.1.5 I cannot do nothing!

I'd like to install 4.2 as soon as it is posted here (I want it stock).

Thanks again
[Samsung Galaxy Nexus] efrant:
Your option is to follow the instructions in the first post to flash yakju or takju 4.1.2.

The issue here is that are not running a stock Google ROM. You are running yakjuxw, which is a Samsung-built ROM, not a Google-built ROM like yakju or takju. It has nothing to do with your CWM.
[Samsung Galaxy Nexus] peikojose:
Thanks for your answer again. I'll have to read from the beginning and try.

And what would I have to do after 4.2 comes out? The same process? I'd like to wait then.
[Samsung Galaxy Nexus] efrant:
If you follow ALL the steps properly in the first post, when the 4.2 update comes out, you can either install it over the air or via CWM.
[Samsung Galaxy Nexus] Edwrib:
Some users reported 4.2 rolling out for galaxy nexus, check android police twitter.

[Samsung Galaxy Nexus] pafaisal:
Hi

My friend has a galaxy nexus with yakjujp. I know he can convert to yakju. But is it possible to convert to takju..?
[Samsung Galaxy Nexus] thephantom:
Yes. The process is the same. He just needs to download the takju files in place of yakju
[Samsung Galaxy Nexus] phonedroid:
Excuse me for the n00b question -

Status: I am on yakjuxw 4.1.1 now. Want to switch to yakju (JZO54K). I already have an unlocked boot-loader.

Question: Is flashing the boot-loader from the yakju 4.1.2 factory image a mandatory step? Or can I just go ahead and flash the system alone, keeping my /data intact?
[Samsung Galaxy Nexus] Unlawful:
You don't have to flash the bootloader and you can flash only the system image but it's recommended to just flash everything to minimise any chance of clashing.
[Samsung Galaxy Nexus] phonedroid:
Thanks, I'll do a nandroid backup, flash the system alone and check if it is able to take me to 4.2 via OTA.

I've seen those lighter 'from-to' files. I am apprehensive since they are just files and there is no page explaining what is for what - or am I wrong?

Plus, that file says, from tajku, I wish to move from yakjuxw to yakju.

EDIT: Flashed the system alone, wiped cache and dalvik and rebooted - it's a bootloop.

hey guys,

you think it's necessary to flash the radioxxx.img and boot.img along with the system.img?

it seems the bootloader is the same as 4.1.2.

thanks.

[edit] never mind, i just read efrant's post in the other thread. sorry!
[Samsung Galaxy Nexus] efrant:
Flash all the images except userdata and recovery.
[Samsung Galaxy Nexus] haskeo:
boot loop

i followed the steps in section D and after i boot my phone the nexus logo just keeps flashing and the phone won't turn on so i tried to reflash the system img but it always gives me an error saying failed exceed buffer size 0x16400000 i tried closing the command prompt and restarting but it still says the same thing. what can i do to fix this?

ok nvm i restarted from section A and now it is working
[Samsung Galaxy Nexus] efrant:
1) Make sure your device is on the LC03 bootloader.

2) Make sure you use a good usb cable and you are plugged into a port at the back if your PC.

3) Make sure your command prompt is running with administrator privileges.

4) Repeat the steps in part D.
[Samsung Galaxy Nexus] Samdroid1:
I've been scanning through this thread and many others and I just want the answers to a few quick questions PLEASE :) I'm currently on a Galaxy Nexus 4G LTE mysid running JRO03O factory image 4.1.1. Since 4.2 was released today, is there any way I can get this update to work on my phone? I know Verizon won't release the update for some time if they do, so maybe I can get it now somehow. Maybe not. Thanks in advanced and please be as detailed as possible if you can. THANKS GUYS! :D
[Samsung Galaxy Nexus] Dr. Sheldon Cooper:
My galaxy nexus has yakjuxw filmware and it is running 4.1.1 Jelly Bean android. I want to upgrade to new 4.2 Jelly Bean. Please help me what to do. P.S. My phone is completely pure not rooted, flashed or anything. It is as it is, completely normal.
[Samsung Galaxy Nexus] chrone:
The factory image for toro device is not out yet, I don't know whether there will be one since Nexus 4 doesn't support LTE, but I do hope they still support toro and toroplus devices though.

You could do harm to your toro device flashing takju factory image. It is known not to do that. Hehe :D

Actually the guide in first post pretty explains itself. The takju 4.2 is out, just convert your yakjuxw to takju 4.2 factory image using efrant's guide. Make sure you backup all of your data to PC before doing the convert. :)

[Samsung Galaxy Nexus] Dr. Sheldon Cooper:
This one looks so complicated. I would like to use mskip toolkit. Tell me what should I do? Root or flash? I have no idea I am newbie in android world. :(
[Samsung Galaxy Nexus] efrant:
If you want to use a toolkit, please ask in the appropriate toolkit thread. Please do not clutter this one with toolkit questions.

If you want to learn, so that you will no longer be a "newbie in the android world":

1) Don't use a toolkit;

2) Read and then read a bit more;

3) Have a look at the first post of this thread and attempt it. I, and others will be glad to assist if you find yourself stuck. No support for toolkits in this thread.
[Samsung Galaxy Nexus] el_charlie:
For a PhD and a guy who graduated from college being a teenager, you're very afraid man.

JK.

Seriously, follow Efrants guide step by step to convert to takju and then wait for the OTA or flash it like on first post.

Cheers!
[Samsung Galaxy Nexus] Samdroid1:
So there's currently no way to get 4.2 on any VZW Galaxy Nexus, right?
[Samsung Galaxy Nexus] efrant:
There are no stock 4.2 ROMs for Verizon. The only way to get 4.2 on a Verizon device right now is via a custom ROM. Have a look in your favorite custom ROM thread.
[Samsung Galaxy Nexus] Zepius:
you could add sprint galaxy nexus to this thread as well. factory images are up it.

Convert yakju to takju without wipe?

Hi,

Sorry if this is a stupid question, but i have it anyway;

Is there a way to flash the takju (4.2) image over yakju (4.1.2) image, without wiping the system and all data? I have unlocked bootloader.

Appreciate an answer, want to get my hands on 4.2! :D

EDIT: Never mind! I found it out in another thread, but didn't figure out how to delete my post..
[Samsung Galaxy Nexus] adam1882:
So just to confirm b4 I try this. I'm on yakju 4.1.2 maguro and using this guide I can upgrade straight to takju 4.2, is this correct.

Also I'm using a mac, so I don't need to install the drivers? Is this also correct?

Many thanks.
[Samsung Galaxy Nexus] efrant:
Correct.

Correct.
[Samsung Galaxy Nexus] adam1882:
Whoop thanks.
[Samsung Galaxy Nexus] hillrider:
I am butting my head real hard here and am at the end of my searching abilities.

I have a takju device bought straight from Google Play that up to now had received nothing but OTAs. No rooting, no ROM apps, nothing whatsoever. I am sideloading the JOP40C upgrade, have the right package, went nuts in finding and installing the USB drivers to get ADB to work, but all of that is in the past. Now the upgrade fails with the following assert error, which I Googled and came up empty:

assert failed: file getprop("/system/build.prop", "ro.build.fingerprint") == "google/takju/maguro:4.1.2/JZ054K/485486:user/release-keys" || file_getprop("/system/build.prop", "ro.build.fingerprint") == "google/takju/maguro:4.2/JOP40C/527662:user/release-keys

Then an unambigious "Installation Aborted".

If anyone has any tips it would be greatly appreciated. There's nothing non-stock on this device--pure as silk!!
[Samsung Galaxy Nexus] efrant:
No idea. Usually that error means that either a) you messed around with your build.prop file or b) you are applying the wrong update or c) or you are using a touch recovery.

If non of those are true, and you really want 4.2 without waiting, just flash the 4.2 images as per the first post except skip the userdata image.
[Samsung Galaxy Nexus] rptw:
Sorry if this question has been asked already, I tried doing a search but did not find anything after a quick look through.

If I already have CWM/TWRP installed, could I just skip to step 7?
[Samsung Galaxy Nexus] spaceman860:
Yes

Sent from my BAKED N7
[Samsung Galaxy Nexus] rptw:
would it also work in stock recovery? if not, why?

also, does this method work on any android device? again, if not, why?
[Samsung Galaxy Nexus] adam1882:
Worked like treat on my yakju nexus, upgraded to takju 4.2 , on a Mac as well. Cheers.
[Samsung Galaxy Nexus] killchain:
Kudos, efrant, very helpful topic.

Did my first flash with your help, my formerly 4.1.1 YAKJUXW (not updating to 4.1.2) is now 4.2 TAKJU (with the appropriate boot, radio, recovery) so hopefully, I'll get to install the next OTA when it comes out (if I haven't flashed another ROM by then, of course).
[Samsung Galaxy Nexus] efrant:
No. The stock recovery only flashes updates that are signed with Google's platform keys.

Assuming you are using the proper recovery for each particular device, yes. (However, if your bootloader is locked, you would not be able to use fastboot commands to get the recovery flashed.)
[Samsung Galaxy Nexus] rptw:
What do you mean by proper recovery? Like the version of CWM/TWRP that is made for that particular device?
[Samsung Galaxy Nexus] M_Shaaban:
Could anyone please share the SuperSU latest version -I believe it's 0.98- that is compatible with JB 4.2/Galaxy Nexus? Can someone confirm that this method works on the JB 4.2 or not? And is it still not resulting in flashing CWM recovery to the phone? I want to keep my stock recovery. Thanks in advance!
[Samsung Galaxy Nexus] pmbabu:
0.97 works as well on JB 4.2/Galaxy Nexus
[Samsung Galaxy Nexus] M_Shaaban:
If I download the 0.98 zip from SuperSU page, would it work or it needs any modifications?
[Samsung Galaxy Nexus] efrant:
Should be ok.
[Samsung Galaxy Nexus] msavic6:
I'm currently on 4.1.2 yakju with unlocked boot loader. I'd like to install the stock takju image, Can I flash the 4.2 image immediately? I don't mind erasing my data on the phone, so I would need to flash boot loader, recovery, radio, system, userdata. Is that correct?
[Samsung Galaxy Nexus] thephantom:
Yes you can
[Samsung Galaxy Nexus] lagin:
Not working

I am not able to flash to 4.2 from yakju.

[Samsung Galaxy Nexus] Littletrick:
Hi there efrant. Thank you for a terrific step-by-step guidance here.

I'm quite new to android world, but have some experiences on flashing roms using toolkit from mskip.

BTW, I can follow your guidance.but I want to ask couple question though.

1. is your guidance here legitimate to use for device running custom rom?

2. i read about clean and dirty installation, is your guidance follow clean installation (i.e wiping all necessary things such as data, cache, system, dalvik-cache, etc before flashing all those .img files)? Is that really necessary to clean everything before flashing or I just have to follow all your step-by-step guidance and everything will okay?

Thanks pretty much all I want to ask. Thank you in advance. Really appreciate all responses here.
[Samsung Galaxy Nexus] efrant:
If you mean can you use this if you are running a custom ROM, then the answer is yes. This returns your device to stock, regardless of what ROM you are running.

Flashing an image will erase and overwrite the specified partition. If you flash the system image, it will wipe the system partition of your device and replace it with the information contained in system image that you are flashing. data and dalvik-cache, along with sdcard, are all stored in the userdata partition. If you follow ALL the steps in part D of the first post, it will wipe EVERYTHING off your device, and you will be starting anew.

See answer above.
[Samsung Galaxy Nexus] Littletrick:
Wow. That was fast.

Yes I'm running custom rom and want to go back to stock.

Thank you very much for your explanation :)
[Samsung Galaxy Nexus] n4speed2:
A Very Thanks to eFrant for the Tutorial,Amazing guide, Absolutely no problem at all, Converted from yakjuxw to yakju and now enjoying 4.2 on my gnex.

Again Thanks,Loving the new update now.
[Samsung Galaxy Nexus] RichardHaro:
I apparently have ClockworkMod Recovery on my phone (or so it seems, from files/folders on my SD card) but I have no idea how to actually access the CWM interface to flash the yakju image

How do I go back to stock recovery or access CWM and flash 4.2?
[Samsung Galaxy Nexus] zAlbee:
Thanks for this. I just did root (using 4.0.2 exploit), Titanium Backup, and converted from 4.0.2 yakjuxw to 4.0.4 yakju using this. Even saved my icons and SMS messages, but lost my Google Talk history and widgets. Oh well, no big deal.

I also like how Google included the flashing script (flash-all.sh) in the zip. Saves a few steps if you're lazy like me. :) Though I didn't use this script, the "fastboot -w update image-yakju-imm76i.zip" command worked just fine in place of flashing boot/recovery/system/userdata separately.

FINALLY got i wanted. From yakjuxw 4.02 to Rooted with exploit, titanium backuped, unrooted, backed up rom with cwm, and flashed yakju 4.04!

many many thanks eftrant!

now, trying to figure out whats the best easiest way to root? my bootloader is still unlocked. and also would like to know how to unroot.

cheers!
[Samsung Galaxy Nexus] Aradfan:
And how can I come back to original state, with titanium backup, or....?
[Samsung Galaxy Nexus] efrant:
How to root

Rooting is just the process of getting root-level access to your build's file system. This is obtained by placing two files in your /system directory. With an unlocked bootloader, this is easily accomplished.

Assuming you already have fastboot.exe on you computer (found in the attachment in the first post) and the drivers set up on your PC, do the following:

1) Download (to your computer) the appropriate version of CWM for your device (or TWRP if you so desire). If you have a GSM version, use this one. If you have a Verizon device, use this one, if you have a Sprint device, use this one;

2) Rename the file to cwm.img, and make sure it is in the same directory as your fastboot.exe file;

3) Download (to /sdcard on your device) the latest version of either Chainfire's SuperSU or Koush's Superuser;

4) Restart your device in fastboot mode and plug into computer

5) Open a command prompt in the directory mentioned above and type: fastboot boot cwm.img

6) Wait for it to boot

7) Navigate the menus the CWM menu on your device and select an option like "update zip from sdcard". Find the zip that you downloaded, and apply it.

8) Reboot. Done.

And no, this procedure does not flash CWM to your device.
[Samsung Galaxy Nexus] efrant:
Titanium Backup will not create a backup of your original ROM. You can do a nandroid backup in CWM before you flash all the yakju images.

Alternatively, if you are using yakjuxw, the original images are already available.

As I had mentioned earlier, I doubt that you will ever need your original version. No one on these forums who has returned their device with yakju has ever been denied warranty service to date.
[Samsung Galaxy Nexus] fpbasilio:
Thanks again efrant! I'm now rooted! :thumbup: :D :thumbup:
[Samsung Galaxy Nexus] quietriot84:
I had this issue and there was an update to 4.0.4 (IMM76D to IMM76I) pushed from google that fixed it for me.

The other fixes were to disable smart reflex (requires root) or change min frequency to 700mhz (also requires root)

Edit *was supposed to be reply to chubiprince*
[Samsung Galaxy Nexus] P-MUX:
Radios and bootloader will not flash?

efrant,

Thanks again for your help. I have followed the directions perfectly and everything has written correctly (reads OKAY after each flash), but my bootloader version, baseband version, and cdma version remain primeLA03 and .FA02, respectively (all from 4.0.3). I am stuck in a boot loop and flashing everything appears to happen normally but when I reboot, it goes back into gummy and then just reboots forever.

Any advice? Why will flashing these images appear successful but change nothing?

Thank you!
[Samsung Galaxy Nexus] efrant:
That's very strange. If you are still seeing your old ROM, then I would guess that the images didn't flash. Not sure why it would have said OK if they didn't flash. Try the process again.
[Samsung Galaxy Nexus] P-MUX:
Still the same . . .

Thanks for that advice. I've tried it again, and still the same thing. I have flashed these images several times, in fact, over the past week. Is there some sort of firmware (like a bios) that could have an error that would prevent new software installation from sticking?
[Samsung Galaxy Nexus] efrant:
Not really.

Maybe try posting screen shots of your command prompt window (as you execute the commands) that I could browse through.
[Samsung Galaxy Nexus] P-MUX:
Screenshots . . .

Thanks, here they are. XDA won't let me post images yet (I am new to this site), but here are the links.

This time, I accidentally flashed the cdma radio as just radio, but then corrected it.

[Samsung Galaxy Nexus] efrant:
Why did the system image flash fail the first time?

Are all the images extracted? i.e., not in an zips?
[Samsung Galaxy Nexus] P-MUX:
It failed because I had not yet unzipped the internal zip file, so there was no system file yet. Which answers your second question . . .

Yes, all were extracted (eventually) using 7-zip.
[Samsung Galaxy Nexus] efrant:
Well, I really have no idea then.

Maybe try erase each of the partitions first, and then flash:

fastboot erase boot

fastboot erase system

fastboot erase userdata

fastboot erase recovery

Then flash them again.

As well, although it shouldn't make a difference, are you using the drivers I linked to in the first post, and the version of fastboot in the attachment in the first post?
[Samsung Galaxy Nexus] P-MUX:
Still looping . . .

Did this, and still nothing . . .

Yes, I followed your guide exactly: using those drivers and the files from your platform tools, as well as using 7-zip. Still nothing!

Is there another way of flashing the images or wiping the phone?
