As it stands now, the only way to revert to a yakjuux (or any other non-yakju) build is to restore a backup that you had done previously in recovery. There are no factory images available (and no leaks either) of any non-yakju builds.

I made a backup of my yakjuux build before I switched to yakju. See here. You can always use that, although I highly doubt you will find a good reason to switch back to yakjuux from yakju.
[Samsung Galaxy Nexus] Wolfglance:
I won't switch back to yakjuux !

I just want to complete my " efrant How To's " great collection. (just in case one day I need it) :D

Thank you chief,
[Samsung Galaxy Nexus] efrant:
No prob! :)
[Samsung Galaxy Nexus] dogblood:
I just followed Efrants sig.. I mean wow.. it was easy! Painless! Thanks Efrant, I left it OEM unlocked seeing as how if I ever need to go back to stock I can always relock it after the restore from CWM.

THANK YOU!
[Samsung Galaxy Nexus] Thorgoth:
great guide.....

thank you for all the info and links and detailed steps..

my used-to-be yakzuwx is no more :D:D:D:D:D

all hail yakzu now!!:rolleyes:
[Samsung Galaxy Nexus] 4walls:
I forgot that unlocking the bootloader was the step that erases the sdcard. Thanks.
[Samsung Galaxy Nexus] ace-user:
does the method in second post works??looks easier than the first method...
[Samsung Galaxy Nexus] Novizxc:
this is for the GSM/HSPA+ or the LTE?

this is for the GSM/HSPA+ or the LTE? or it's the same?
[Samsung Galaxy Nexus] JoshuaLow_:
If i am on a 4.0.2 stock firmware with yakjuxw,can i still use this tutorial to flash it straight to 4.0.4 yakju?
[Samsung Galaxy Nexus] efrant:
You'll be on 4.0.1 though, and you'll have to wait for the OTA updates, or flash them manually. Method in post 1 flashes 4.0.4.
[Samsung Galaxy Nexus] efrant:
This is for the GSM version, but you can use the same procedure for the LTE version, but with 3 changes: download the mysid image from Google's page instead of the maguro one, modify the commands in the step by step to reflect the names of the mysid images, and flash the additional radio that the LTE version has.
[Samsung Galaxy Nexus] efrant:
Yes.
[Samsung Galaxy Nexus] ace-user:
since 4.0.4 is already out thru OTA for yakju right?if i flash yakju,although i will be on 4.0.1 but i'll still get the OTA for 4.0.4 immidiately..am i right?
[Samsung Galaxy Nexus] efrant:
Possibly, but not necessarily.
[Samsung Galaxy Nexus] neo158:
As efrant said, you may get it immediately but my Galaxy Nexus only got the OTA for 4.0.4 last night.
[Samsung Galaxy Nexus] Toxvaerd:
Im considering to change to yakju from yakjuxw, but i was hoping to see a Danish Dictionary with the next update. I have been following the update results here, and as far as i know the new yakju 4.0.4 didnt include Danish Dictionary.

And also, it seems like the yakjuxw is all over the place. I thought it might was a european version, so the ones missing Danish, Swedish and Norwegian dictionary would get this with the yakjuxw update. That just doesnt make sense, if the yakjuxw is all over the world. Is yakjuxw really a regional build, so there is hope for some nordic dictionarys in the update?
[Samsung Galaxy Nexus] funkadesi:
Thank you so much for the tutorial OP!

This was a smooth upgrade from Yakjujp 4.0.2 to Yakju 4.0.4 :-)

One question I have is... The next time Google releases an official update for Yakju... I should expect the OTA like other Yakju devices, correct?
[Samsung Galaxy Nexus] efrant:
Yes, you are correct.
[Samsung Galaxy Nexus] MilkPudding:
Just wanna say thanks for the extremely easy and hassle free upgrade.

My battery life has improved significantly and the phone feels so fast and smooth now.
[Samsung Galaxy Nexus] onthecouchagain:
Question: the steps in the OP is okay to do with a Mac? (Sorry if it's been asked; there are 71 pages on this thread). Appreciate the help...
[Samsung Galaxy Nexus] felito6985:
I also wanted to thank the OP and Efrant for the step by step guide. :D
[Samsung Galaxy Nexus] onthecouchagain:
Honestly, what's the time difference between Yakju or Yakjuxw build? Are we talking about a few days after Yakju gets updates, or few weeks, few months?
[Samsung Galaxy Nexus] efrant:
It will work with a few changes:

1) you have to put ./ before each command (so fastboot flash boot boot.img will be ./fastboot flash boot boot.img); and

2) you need to use the MacOS version of fastboot. I did not include it in the original post, but I've attached it to this post.
[Samsung Galaxy Nexus] efrant:
Based on past updates, anywhere from a couple of weeks to a couple of months (aside from one exception -- which came a few days after yakju).
[Samsung Galaxy Nexus] onthecouchagain:
Thanks for the fast response. I may end up using my parents' Windows PC, just to keep it simple.

One more question though: I hear that the GN doesn't get recognized as a USB drive. I assume this is what is meant in step 1 about having all the drivers installed to recognize it? If so, where/how do I get the drivers?

(I do not have the GN in hand yet, so this is all a little abstract to me).
[Samsung Galaxy Nexus] efrant:
I'm sure putting ./ in front of the commands won't be that much more complex ;)

Read step 1 again ;)
[Samsung Galaxy Nexus] onthecouchagain:
Oh my, yes. :o
[Samsung Galaxy Nexus] Novizxc:
ended in the 4.0.2 or 4.0.4?

just one more question, though not quite understand if after doing all the steps that are in the post 1, when I finish my galaxy nexus will be in version 4.0.2 or yakju yakju will be on the 4.0.4?

thanks
[Samsung Galaxy Nexus] stormaker:
With bootloader unlocked, still can update via OTA in future, read from other forum that the OTA update fail n just freeze?
[Samsung Galaxy Nexus] efrant:
4.0.4

---------- Post added at 12:05 PM ---------- Previous post was at 12:04 PM ----------

Yes.

Although the update will appear here on XDA before you get the OTA anyway... :)

They are wrong, or you misread.
[Samsung Galaxy Nexus] JoshuaLow_:
Question! If i upgrade from stock 4.0.2 yakjuxw to 4.0.4 yakju and i wanna send it in for warranty,i just have to use gnex toolkit unroot function to flash a stock firmware and send it in?If yes,what firmware should i flash back? Thank you!
[Samsung Galaxy Nexus] efrant:
There is no yakjuxw firmware available. But you can back-up yours.

Unlock your bootloader, install CWM and back-up. Then, if you ever want to revert to yakjuxw, all you have to do is restore your back-up.
[Samsung Galaxy Nexus] JoshuaLow_:
Okay can i use this tutorial to backup?http://xdaforums.com/showpost.php?p=21266325&postcount=239So flash these backed up .img files and send it in for warranty?No need to lock bootloader?
[Samsung Galaxy Nexus] efrant:
Yes

I would re-lock the bootloader only just before sending it in: boot into fastboot mode, open a command prompt and type: fastboot oem lock
[Samsung Galaxy Nexus] pookguy88:
does this root the phone too?
[Samsung Galaxy Nexus] efrant:
No.

Hi efrant,

in your [how to's] Backup a non-yakju ROM step 5 (the second #5) :

" 5) Boot CMW: fastboot boot clockwork-5.5.0.2-maguro.img "

the command shouldn't be ? :

fastboot boot recovery-clockwork-5.5.0.2-maguro.img

since the file in the link is : recovery-clockwork-5.5.0.2-maguro.img

or is it me who is missing something ? :)...also a typo there is in "CMW" instead of "CWM".

Thank you,
[Samsung Galaxy Nexus] efrant:
You are correct on both counts! Typos. I'll fix them. Thanks.
[Samsung Galaxy Nexus] ace-user:
hmm...wat do u mean not necessarily?:confused:

since 4.0.4 is out for yakju thru OTA and other nexus with yakju have receive the 4.0.4 update,so technically i'm supposed to get the update if i flash to yakju...isnt tat right?:confused:
[Samsung Galaxy Nexus] IRageQuitHard:
Wait, so after flashing yakju, would I have to flash the radio or anything so it would be just like a yakju nexus right out of the box? What would I have to do besides relocking the bootloader?
[Samsung Galaxy Nexus] efrant:
Not everyone on yakju has received the update to 4.0.4. There are still tons of folks who have yet to receive it. What makes you think that you will receive it before (or later than) them?
[Samsung Galaxy Nexus] efrant:
If you follow the steps I posted, including the optional steps, you will be just like a yakju nexus out of the box, except for one thing. You still need to relock the bootloader. You do this by typing: fastboot oem lock (although I don't recommend you do that unless you have to return your phone for warranty.).
[Samsung Galaxy Nexus] JoshuaLow_:
Oops so no need for flashing of .img?Just re-lock bootloader and send it in?

Also i provided a screenshot,my build number can be used for this tutorial right?

Thank you!
[Samsung Galaxy Nexus] stormaker:
Im trying to backup my yakjuxw rom with cwm before switching to yakju, but im getting error saying :

Can't mount backup path

E:Can't mount /cache /recovery/log

E:Can't open /cache /recovery/log

E:Can't mount /cache /recovery/last_log

E:Can't open /cache /recovery/last_log

May i know whay is that ?
[Samsung Galaxy Nexus] IRageQuitHard:
Thanks so much! I'm getting my Nexus tomorrow (USPS somehow slowed down yesterday, but now is <15 miles away from me), so if I don't have a yakju build, I will flash the bad boy. Just wanted to know, thanks so much, as stated again lol
[Samsung Galaxy Nexus] efrant:
No, what I meant was keep your bootloader unlock until you have to send it in.
[Samsung Galaxy Nexus] JoshuaLow_:
Thanks mate:)
[Samsung Galaxy Nexus] ace-user:
oo...i thought eveyone on yakju have received the update...sorry...

so i just follow the steps on the first thread and i would be on stock 4.0.4 yakju?

i'm a newbie,so i apologize if i asked too much...
[Samsung Galaxy Nexus] amrs:
Successful update and thanks

Hi all, updated my GNex last Friday, from yakjuxw 4.0.2 to yakju 4.0.4

using the instructions in the first post of this thread. Used a

Windows 7 laptop and the "Universal Naked Driver" from

http://xdaforums.com/showthread.php?t=1379875

Everything went fine with the update. Got the welcome email from

Google and all. Very impressed with the (idle) power now, I didn't use

the phone much over the weekend, but I still had 27% left on Monday

morning. Feels like an improvement but I have no actual comparison.

I also like the new quick menu (it adds two new buttons to the old

three) in the browser and general snappiness.

Google Play refused installing free apps after the update, I downgraded to a previous version and that seemed to fix it.

It didn't fix my Bluetooth issues, but I knew that going in. Maybe in

4.0.5...

Oh, one question. I didn't unlock bootloader since I had done that

earlier and I kinda thought my phone wouldn't be wiped... So what part

of the update process causes the wipe?

Anyway, big thanks to Efrant for the instructions.
[Samsung Galaxy Nexus] efrant:
Yes
[Samsung Galaxy Nexus] efrant:
Yeah, that is the same driver I have linked in the first post.

Although this may look like an upgrade process (updating from 4.0.2 to 4.0.4), it is NOT. This is a "clean install" method, which does not update anything. It wipes whatever you have and installs a fresh build. For those that want to upgrade their existing builds to 4.0.4, you will need to look at the update link in my signature. However, at this point, we only have update links for yakju, mysid, and yakjuux.

To answer your question, flashing the userdata.img file wipes your /sdcard. Having said that, if you were already on yakju 4.0.2, you prob wouldn't have to flash that file, so it would retain your data.
[Samsung Galaxy Nexus] stah333:
Hey guys.

I have some questions . I ve read alot of psots and i want to ask this :

If i have unlocked bootlaoder i dont need to lock it to get OTA updates or whatever reason to do this is there? If i ve flashed yakjuxw to yakju with 4.0.2 udapte from here using fastboot method some tiem ago when there was no 4.0.4 here i should get the OTA to 4.0.4 ? And finally - when the 4.0.4 OTA came out ? Because i still didnt get it .
[Samsung Galaxy Nexus] efrant:
You will get the OTA with an unlocked bootloader.

The OTA to 4.0.4 will come for you when it comes. If you want it sooner, install it yourself. Instructions are in my signature.
[Samsung Galaxy Nexus] Novizxc:
thank you

hey guys, did you all like this in post 1, and everything was great, I felt very nervous at first but is actually quite easy and hassle.

seriously thank you.
[Samsung Galaxy Nexus] stormaker:
I would like to thanks efrant too for the details instruction even noob like me can understand.

But, i followed ur instruction on backuping the non-yakju rom, but it sent my phone into bootloop, do u know the reason why ?
[Samsung Galaxy Nexus] efrant:
No idea. That procedure does not flash anything to your device, so I find it hard to believe that it would give you a boot loop.
[Samsung Galaxy Nexus] stormaker:
Well it might be mistake at my end. Btw, by doing "fastboot flash recovery recovery.img" should already get rid of the cwm n revert back to stock recovery right ?
[Samsung Galaxy Nexus] stah333:
Thanks for clearing that up efrant. I ve got 1 more question. What is the diffrence if i have unlocked laoder besides that i cant flash images ? And if i lock the laoder and then decide to unlock - is it that simple to write "fastboot oem unlock" again and itll unlock without problems ? ( I ask because some ppl say if You lcok then there is a problem to unlock again ; o )
[Samsung Galaxy Nexus] Haroundb:
First thanks a lot efrant for the step by step, but the question , what are the benefits of keeping the bootloader unlocked?

Thanks.
[Samsung Galaxy Nexus] LionRock:
I have also yakju version but still have no update 4.0.4 :/ Wehats wrong with google? iOS is updated right away at google you must wait two week and even more? This is unbelievable....
[Samsung Galaxy Nexus] Haroundb:
Another important point, My phone power button started acting up, the phone is one week old only! I am trying not to relate this to fact that I flashed my phone to Jakyu ??? Can't there be any relation?

Thanks again!
[Samsung Galaxy Nexus] stormaker:
its rolling out slowly, u may try the below method to get it faster ...

1 go settings/apps then hit the all button at the top

2 Scrll down to goggle service framwork then press it to open it

3 Hit the clear button

4 go to settings/about phone/System updates the date will be 1969 or 1970 this is ok

---------- Post added at 05:36 PM ---------- Previous post was at 05:32 PM ----------

Some ppls claim they tried as many as 20 times b4 get their OTA update. Unfortunately what u can do is wait or flash manually.

Still the same :/
[Samsung Galaxy Nexus] stormaker:
Sorry to hear that, if u tried hard enough n still cannot get it, then either wait longer or flash manually.
[Samsung Galaxy Nexus] stah333:
Mate, I jsut made it update. I used the method described by stormraker. First time was no GO , then i did the same thing and no go again , then i made this - i made the same thing stormraker wrote but did not check for udpates . i cleared google services framework and after that i turned off the phone and turned it on again - then boom - the update popped out right after the phone booted. Try this - you may be as lucky as I was.

Oh , 1 more thing - i ve changed to wifi connection from 3g when doing the 3rd try.

I hope this helps.

EDIT:

By the way. Didnt google state that they skip 4.0.4 update for GSM version and release 4.0.5 in the beginning of april isntead ?

Yes I have wet screen protector installed yesterday, but what that got to do with the power button?

And what can I do to fix this problem? remove it or what?

Thanks a lot!
[Samsung Galaxy Nexus] stormaker:
Its kinda well known that wet screen protector mess with the power button, the water find their way in. U can try to google search for this issue. If u're lucky, it will be fixed by itself after it dried up properly, internally. Somes say blow with hair dryer, soak in rice to expedite the process. If all failed, then it could be permanent damage.
[Samsung Galaxy Nexus] Haroundb:
So the damage can't be repaired if we assume it is perminant?
[Samsung Galaxy Nexus] stormaker:
Should be repairable, but im not sure what part will need to be replaced n the cost. Right now, hope it will be fine after few days, which is most of the case.

"12) Optional -- Flash the recovery partition: fastboot flash recovery recovery.img"

Thanks for the intructions and I flashed my GN to 4.0.4. yakju wthout any issue. But after I restored my apps and data. I found that CWM Recovery is still in my phone, might be ROM Manager flashed that back to my phone automatically.

If I re-flash the stock recovery image, would that un-install CWM Recovery? I want to uninstall it so I may get OTA update in future.

Thanks
[Samsung Galaxy Nexus] efrant:
Yes, if you re-flash the stock recovery, it will over-write CWM. But you can do that at anytime. As soon as you get the OTA notification, you can re-flash the stock recovery and update. However, the link to that update will most certainly be posted here on XDA before you get the OTA notification, and if you want to update, it will be easier with CWM (unless you have root).
[Samsung Galaxy Nexus] stormaker:
Can i check with u, whether u able to receive app updates like google play store 3.5.16, google maps 6.5, gmail 4.0.5 ? Thanks!

I receive none of the update, but thats not the case when im in yakjuxw.

Or anybody?
[Samsung Galaxy Nexus] OpusX11:
Efrant,

thanks for the guide, I just flashed manually from 4.0.1 yakjuux to 4.0.4 yakju.

I unlocked the bootloader, and then booted to CWM Recovery (without flashing it) by following your instructions in post (#239) to take a nandroid prior to flashing, but kept getting several errors. Initially it couldn't find the backup path. so I rebooted without the cable in and ensured that everything was mounted in CWM first, and tried it again. This time, it began backing the first couple of partitions but error'd on system. so i decided to just flash yakju anyway and figured if I really needed to back to yakjuux I would restore your posted backup.

thanks a bunch.
[Samsung Galaxy Nexus] efrant:
That might be my mistake and I apologize. You need to boot into the OS at least once before CWM sees the partitions properly. I'll update the post accordingly.
[Samsung Galaxy Nexus] OpusX11:
no need for the apology, enjoying 4.0.4 :)

thanks for the prompt reply though, I'm sure that might save others some research time in case they encounter issues.

a quick question please.

Are these below 2 terms the same? (since you use them in your great

[how to's]).

reboot into bootloader mode

reboot into fastboot mode

Thanks,

Run through all the steps again.

Yes they are the same. Sorry for the confusion.

Mysid is the LTE version of the galaxy nexus
[Samsung Galaxy Nexus] TooLegit7:
Thank you. What does that mean in respect to yakjuxw/yakju
[Samsung Galaxy Nexus] TooLegit7:
Here is my screengrab
[Samsung Galaxy Nexus] rubiconjp:
Nothing. Your GN is a Verizon LTE phone and will be updated by Google. You should not be concerned with the yakju issue, which only applies to GSM GN.
[Samsung Galaxy Nexus] TooLegit7:
okay great thank you
[Samsung Galaxy Nexus] josteink:
I had that issue as well until I updated and did a complete wipe (fastboot -w update blabla.zip). After that it booted fine.

Fortunately I had run titanium backup prior to starting though. Only thing I lost was some originals of pictures I had taken when testing the camera.
[Samsung Galaxy Nexus] :
But just To answer your question yakju is the original firmware image from Google which gets updates first. And yakjuxw is a firmware from Samsung which means when Google rolls out an update yakjuxw gets it 1-2 weeks later then yakju. That's the only reason for changing.
[Samsung Galaxy Nexus] invisible_touch:
Thanks to all, I'm going to see on the site samsung.de
[Samsung Galaxy Nexus] dwallersv:
Okay, I want o get in on all this Japanese Yakuza goodness :D:D, but my VZW GNex, bought while slobbering all over the place Thursday morning last week, yields system info that makes no sense:

What is product "mysid"? Seems I'm not on either version of yak*. What do I do? What does it mean?

I just want to have a real Google phone too! :D

There are some intriguing things there that make me wonder if stock from Verizon I'm already hooked in to the Google servers for updates, etc. Look at the Fingerprint; the Host.

I'm too new at the whole Google developer phone thingy to make sense of it all. I was technically savvy on my Epic 4G... having to learn new dev/flash/mod techniques, tools, etc. for the Nexus, so I'm a wet-behind-the-ears noob again.

Anyway, am I already tied to Google instead of Sammy and/or Verizon for my updates? That would be my guess based on the info above. If so, the question is, HOW? All I've done so far is root.
[Samsung Galaxy Nexus] rubiconjp:
You're good to go. You're already running latest 4.0.2 and your LTE GN will be updated directly by Google.

This yakju issue only applies to GSM GN.
