I have galaxy nexus phone. It is bought from France. How to know the device filmware version and to convert it to yakju international version?
[Samsung Galaxy Nexus] efrant:
Look in Settings - > About phone, and read the build number.

But it doesn't matter. You can change any GSM version to yakju.
[Samsung Galaxy Nexus] envidia:
efrant, the bootloader of my Galaxy Nexus keeps getting locked after every 'fastboot reboot-bootloader'.

Do you have any idea what's happening? I can't complete all the steps because of this. It's really strange.

Thank you for your guide.
[Samsung Galaxy Nexus] Wolfglance:
Hello Efrant,

I am not sure if you already answered this question regarding the " how to root " :

What's the difference between ChainsDD's Superuser and Chainfire's SuperSU ?

Thanks in advance,
[Samsung Galaxy Nexus] efrant:
I have never heard that before. So you're saying that when you enter this command: fastboot oem unlock, it succeeds and your bootloader is unlocked, and then when you enter this command: fastboot reboot-bootloader, it re-locks it and you no longer see the lock sign on the Google splash screen?

What's the difference between a Coke and Pepsi? Both are colas. They have have a slightly different taste, but they are essentially the same. Made by two different companies though. Same goes for Superuser and SuperSU: essentially the same, slightly different look, but made by different devs.
[Samsung Galaxy Nexus] envidia:
Yes. A friend bricked the phone after trying to update it 'using some kind of Odin mode' (his words), so I'm trying this guide to revive it. The thing is, it never ends booting up, it hangs on the multicolor flash animation.

So, when I'm on fastboot mode, I do 'fastboot oem unlock', accept the prompt on the phone, then it shows is unlocked in red color text. Then I do 'fastboot reboot-bootloader' and 3 seconds later, when the bootloader appears again, it shows the bootloader as 'locked' again, and it is, because I can't flash the images.

I don't know what else to do. I'm on Linux, the phone is recognized without installing any driver.

Thanks again.
[Samsung Galaxy Nexus] efrant:
Your friend Prob flashed the wrong bootloader in odin. Try flashing an ICS odin package. The you can find a couple in the dev/general section.
[Samsung Galaxy Nexus] Gucci.Nexus:
you are right... sorry for clogging up the thread with my window noobness.

btw i flashed takju successfully. however, i am going to flash yakju instead, because it updates sooner (i think). also, in the search for the best radio that will have the least dropped calls. thanks so much !
[Samsung Galaxy Nexus] efrant:
No one knows if yakju or takju will get updated first. And we won't know until the next update starts rolling out. My guess is that they get updated the same time.

There is no easy way to determine which radio is best for you. Just try a bunch out for a few days each and see what works best for you.
[Samsung Galaxy Nexus] BlueBagodah:
I'm fairly certain this is a stupid question, but that's the kind of day I'm having.

Do I need to install adb on my computer for all this to work? If so, is there a specific folder structure that I need, or just the root of my c: ?
[Samsung Galaxy Nexus] efrant:
No you do not.
[Samsung Galaxy Nexus] BlueBagodah:
Many Thanks @efrant! You really should have a donate button. I finally got myself yakju'd and on the newest build. Very happy man now. I've even put off thinking of buying the Galaxy Note for a week or two! ;-)
[Samsung Galaxy Nexus] toxicneo:
Hi,

I got my galaxy nexus phone from the US and using the phone in india

Android version is 4.01

Baseband version is I9250XXKK1

Build Number ITL41F.I9250XEKK9

Product : Yakjuxe

Device Name: maguro

Bootloader: PRIMEKJ10

Everytime I got a notification saying system update is available my phone boots and after some time i get the android symbol with the red status. After a few seconds it again boots and my phone is not updated.

Now i want to install google stock in my phone.Since I am a beginner to rooting and flashing , is it better to use the Gnex toolkit ? Kindly let me know which build will work in india ?

Thanks in advance
[Samsung Galaxy Nexus] efrant:
You are seeing the Android with the red because something you have is not stock. Did you flash a new radio? A new kernel? Did you (or any of your root apps) modify/delete any files on /system? If you answered yes to any of these questions, you will have to undo what you did for the update to install.

Alternatively, you could flash a yakju build (see link in my signature) which will take you directly to the latest build (although it will wipe).

In any case, if you have root (and before you flash yakju), could you look in the log files in the /cache directory and post the contents -- we are looking for the name of the update file (which will end with .zip). Thanks.
[Samsung Galaxy Nexus] chubiprince:
Sir, I think there is something wrong with the radio or with unit after the update. Before the update, I am always connected to the internet using 'data connection'. I can anytime stop and turn it on every time that I wanted to. But after updating my radio, 'data connection' always stops every time GNex activates the sleep mode. And it is giving me a headache... it is interrupting my downloads. Is there a way to fix this?
[Samsung Galaxy Nexus] fpbasilio:
Is there a way to backup (and restore later ) my app datas, game saves. Before I go through the process of yakjuxw to yakju? I know it can be done with titanium backup but I don't have root right now.

If I check the backup and restore option in android settings, does the backup include game data? Game saves? And would it automatically restore app data after I flash yakju?

Its the only thing keeping me from doing this seemingly easy guide. :D
[Samsung Galaxy Nexus] efrant:
This is an issue that many users are experiencing on 4.0.4.

If you search, you can find many threads. Here is one: http://xdaforums.com/showthread.php?t=1555733

There is a fix (you will have to search for it, as I've never used it -- I never had the issue). Otherwise, you can flash back to 4.0.2
[Samsung Galaxy Nexus] chubiprince:
Mine was just loosing the data connection. Thanks sir.
[Samsung Galaxy Nexus] efrant:
Is your bootloader unlocked? If so, then just root and install Titanium backup.

If your bootloader is still locked, and you are on 4.0.2, you can get root by following this. Then install Titanium Backup.

If your bootloader is locked, and you are on 4.0.4, then use this.
[Samsung Galaxy Nexus] fpbasilio:
Thanks efrant.

My boot loader is locked.

I'm on 4.02 but build number says: ICL53F.I9250XWKL2

Would the first link work?
[Samsung Galaxy Nexus] toxicneo:
Thanks efrant for your reply... This is actually the NTT docomo SC-04D 'GALAXY NEXUS model. So i didnt do anything in my phone. Moreover I dont know to flash my phone nor install new kernal and all. Is it advisable to use Gnex toolkit which has the steps and folders were u need to keep the installables or shld i follow the steps provided by you. I am afraid incase if i do my flash my phone to the yakju build will ter be any pblm with my phone since i am using the phone in india.

Thanks for your guidance.
[Samsung Galaxy Nexus] Aradfan:
I have a yakjuxw version with bootloader locked. My question is, will the method described in #1 Post will void my warranty?
[Samsung Galaxy Nexus] geemaan:
Any flashing performed through unofficial channels voids the warranty. This is the reply a Vodafone.ro forum moderator got when he asked Samsung Romania.
[Samsung Galaxy Nexus] efrant:
Unlocking the bootloader technically voids the warranty, BUT, we have Nexus devices, so the bootloader is re-lockable, so no one will know the difference.
[Samsung Galaxy Nexus] Aradfan:
Ok, I will ask the store from where i bought the phone if it voids the warranty and see how they react :). If i do this even if i lose the warranty can i come back to the original "package" ( android ver., radio ver., etc...)?
[Samsung Galaxy Nexus] efrant:
Of course they will say it will void the warranty.

And yes, you can return it to the same state as out of the box, and no one will be able to tell the difference.
[Samsung Galaxy Nexus] qortuba:
Very helpful information, i couldnt wait for samsung to push the JB update since i have the HK/Chinese version of Gnex, so i was tempted to do it and following the steps you provided was easy and within hour i have got myself some JB.:good:
[Samsung Galaxy Nexus] envidia:
Thank you efrant. Last night I tried what you suggested, following the instructions on this thread: http://xdaforums.com/showthread.php?t=1827685

It all went well, tho the process lasted almost 30 minutes (which I think is a little too much), but anyways, it completed successfully. The thing is, when rebooted, the phone is still bricked. It keeps playing the flash animations.

Now I'm reading again your reply and I noticed you said 'try flashing an ICS odin package'. Maybe the problem was that I flashed a JB package, could it be? I'm trying with this thread in a few hours: http://xdaforums.com/showthread.php?t=1586807

Thanks again.
[Samsung Galaxy Nexus] envidia:
Ok, tried with the ICS Odin package and I'm getting the same result: endless booting.

What I noticed is that in fastboot mode, the bootloader never changes, even after following this guide, or the 2 flashes through Odin that I did. It's stucked at PRIMEKK15.

Any ideas what else could I try to revive the phone?
[Samsung Galaxy Nexus] efrant:
Well, that is indeed a problem. 4.0.2 should work fine with the KK15 bootloader. Try flashing this Odin package.
[Samsung Galaxy Nexus] envidia:
efrant, thanks again. Tried that as well: no luck. It never passes the color animations.

I keep reading that if the phone can boot into fastboot and/or recovery, then it's not bricked and can be resurrected, but I don't know what else to try.

Any ideas?
[Samsung Galaxy Nexus] efrant:
I'm out of ideas. If neither odin or fastboot can flash the bootloader, it may mean there's a hardware problem.

You can maybe try OMAP Flash (look in the "basics" link in my sig. Should be a link to it in the second post.

Then try using odin or fastboot.
[Samsung Galaxy Nexus] envidia:
Thank you efrant. I created a new thread describing the problem here: http://xdaforums.com/showthread.php?p=32113378

I will be trying the OMAP flash. I'm a little scared though, I don't want to make things worse.

It's basically the same as flashing the stock recovery. Download CWM and flash it via "fastboot flash recovery name-of-cwm.img".

efrant advised us to uninstall any Samsung drivers or the pdanet drivers. There is pdanet is installed in my pc. Can anyone advice me how to uninstall it...?
[Samsung Galaxy Nexus] efrant:
If your phone is being recognized, and everything works fine (i.e., "fastboot devices" works when you are booted in fastboot), then no need to uninstall them.

Thank you efrant..Everything done better with the help of your detailed guide. After 1 hour I got the OTA update for 4.1.1. Now it yakju. Hope that I will get future updates on time.

Hi

I am on stock 4.1.1 yakju. To make a nandroid backup, I flashed recovery CWM 5.5.0.2. but not flashed superuser. And when I restarted the phone it rolledback to stock recovery.

My question is, since I flashed the custom recovery, will I receive the future OTA...? or I have to flash the stock recovery again...?

[Samsung Galaxy Nexus] efrant:
Ok, but the flash command is still wrong for one of them. See the first post. And are you sure you renamed them the correct way? I wouldn't rename them, just so you're sure you are flashing the right one.

[Samsung Galaxy Nexus] efrant:
If you have the correct images. But you don't. You are trying to flash Verizon images to your sprint device...

Go to the Sprint Development section and have a read of some of the threads there. There must be a thread with Sprint images in there. If so, then you can use my guide with those images. If not, I know there is a "return-to-stock-using-odin-for-sprint" thread in that section.

no service

Hello,

So I followed your guide perfectly and everything worked without any failures. I rebooted my phone and everything is great...but I have no service. I even went through all of the steps again and it is still not working.

The reason I am doing this is because I am taking my phone into Verizon tomorrow to swap it out as I always have 1-2 bars in full service areas.

Any insight?

No idea. If everything flashed ok it should have been fine.

Ugh, I don't know what to do. I can't figure out why it isn't accepting any service.. I've even took out my sim card and put it back in.

Hi

I'm new (to both, this forum and android phones in general) and I seem to be stuck.

I tried installing the drivers, but unfortunately, Windows keeps installing it successfully everytime, even with USB debug mode activated. I've tried updating it anyways (like efrant previously suggested to someone else with the same problem) but i keep getting a "the best driver software for your device is already installed - MTP USB Drive" message.

I've done some research, and apparently the problem may lie with Windows storing the drivers and installing it regardless of if auto-update is disabled, but of course, I may be wrong. I've also tried uninstalling the driver via Device Manager several hundred times, but still no luck. Could someone help me?
[Samsung Galaxy Nexus] efrant:
For those of you having trouble with installing the drivers, try forcing it to update. Don't let it choose automatically, select "install from a list" (or whatever the option is, and then select the "don't search, i will choose the driver to install". Hopefully that works for you. Otherwise, maybe find a good windows forum and ask there, as there may be "windows driver experts" over there -- this is not really android or phone related.
[Samsung Galaxy Nexus] CloakedUltraling:
driver issues

>>>>

Bugger me, please feel free to ignore my question for now, its exactly the same as the last question asked.....Sorry about that

<<<<<

I can never get pass the driver installation D:

I have tried various ways from different sources, this is actually the way I would most prefer if it works, since I totally agree with OP(efrant) where it is best to understand what I am doing from step to step.

Now onto my problem;

I tried following Bourne-nolonger's post on installing the drivers. I read through the whole post before going about it because this is my first time attempting anything like this.

Everything seems fine, my comp recognises my phone as Galaxy Nexus under portable devices so I went on and start the actual installing process.

However, when I enabled USB Debugging, the comp still recognise my phone as Galaxy Nexus instead of "Android 1.0", and there's also this "Samsung Galaxy Nexus ADB Interface" that popped up under "Android phone".

I tried numerous stupid things myself including and at one point, with USB debugging on, in device manager, the Galaxy Nexus is still recognised, but Samsung Galaxy Nexus ADB Interface is no longer there, instead, there is this "Galaxy" shown under "other devices" with a yellow triangle and a exclamation mark. So, without knowing what I'm doing and being frustrated, I right clicked this "Galaxy" and updated driver, chose the Naked Driver 0.7 and it actually updated it......

But I soon found out this is not right, because instead of showing a pop up window that says the bootloader is successfully updated, it said the ADB interface is updated.....and I was like "oh no this is so F$&Ked up...."

So basically, I feel like my laptop always have its own driver for my GN installed even after going into Device Installation Settings and confirmed that I do not want windows updater to update the drivers. Therefore unable to install the proper drivers correctly....

Can someone please lend me a hand here? Really need some help.....

Much thanks guys!!
[Samsung Galaxy Nexus] efrant:
As stated in the first post, there are TWO (2) drivers that can be installed: the ADB driver and the bootloader driver. The ADB driver is not required for the purposes of this guide, but you should install it. The one that needs to be installed is the fastboot (or bootloader interface) driver. You CANNOT install this driver UNLESS your device is booted into the bootloader (i.e., fastboot mode). So, since you did not boot into the bootloader, there is no way that you could have installed it...
[Samsung Galaxy Nexus] CloakedUltraling:
thanks!

hey efrant,

Thanks for the reply!

I think I have confused myself by following steps without thinking through what they are suppose to do. Now with your reply and my "rethink", its all making sense :D

One thing to remind the rest of the noobs like me though, is that if you are following bourne-nolonger's steps, when you get to the "update driver" part with your device booted normally, and USB debugging on, you should get a message saying something like "ADB interface updated" instead of what is shown in the screen-shot where its something about the bootloader....I think bourne-nolonger may have posted the wrong screen shot there :D

Also, to those who are using W7 Home Premium, it seems to be a common problem where your computer would just ignore your settings to stop it from installing drivers. Try editing this registry, it worked for me; (if you dont know how to edit registry, google it)

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows

when you find the windows registry, right click it and add a new key called "DeviceInstall", and then add another key UNDER DeviceInstall called "Restrictions".

Now right click on Restrictions and add a DWORD, and set that DWORD to 1.

hope it would work for whoever is out there like me :D

Thanks. Maybe shoot him a quick PM and let him know (and let him know how he can add anything else to make it clearer).

Reboot into the bootloader. It should go away. Go ahead with the steps. Don't worry, it is almost impossible to brick your phone using this method.

Are all GSM Gnex compatible with both yakju and takju builds ?

Hi Efrant,

The original build for my GSM Gnex was yakjuux. Last july, I successfully followed the procedure in this thread to convert my GSM Gnex from yakjuux to yakju build.

I now would like to use the same procedure in order to flash the latest factory image with JB 4.1.2 for my phone. However, the only version available on Google's website is the takju build (takju-jzo54k), not the yakju build.

Can I use this factory image instead on my phone ? In other words, are those two builds interchangeable (or both compatibles) for a GSM Gnex like my phone ?

Thanks.
