[Q] Possible root without unlocking?

I've just bought my Galaxy Nexus for two days to replace my dead Nexus One.
The UI of ICS is so great but I miss the function from DEVs, like vibrate when the call made.
I have rooted my Nexus One without unlocking the bootloader and I would love to root my Galaxy Nexus without unlocking too.
Is there any DEV going to work on this?

I don't believe anybody is working on this since BL unlock is so simple, and there aren't really any disadvantages (that I know of). In order for root to occur without BL unlock, there would have to be an exploit found in the stock image. Is there a particular reason you don't want to unlock it? You have only had the phone two days, so I imagine your data loss won't be that big of an issue.

And rooting doesn't? After all, it does allow for modification/deletion of system files. In any case, you can re-lock it just as easily.

Accidentally thanked you haha - missed the quote button.
You can lock it if you have to send it in or return it, you know. The lock command is just as simple as the unlock!

Rooting doesn't make the splash screen change (the lock under "Google"), so it can be easily unroot by deleting related files in the system and make it look like stock.
Are you sure a unlocked devices can lock again? Nexus One can't do this.

Yes, "fastboot oem lock" will re-lock the bootloader and make the padlock go away. Here is the write-up by droid-life (I can't view it at work, so I hope it has the right info!)

Mine one is the GSM one, I have searched on Googles, there is no GSM version re-lock tutorial there, so I doubt GSM version cannot re-lock.
And I don't have the stock image.

I thought the GSM factory image was pretty widely available?

I am fairly certain people with the GSM variant have re-locked their phones, but I would check the Nexus android development section (GSM) for proof.

I've tested relocking and can confirm it works fine

I feel like this is a myth. You're not using an exploit, or anything like that, you're using a manufacturer provided tool to unlock the bootloader. Taken from android.com:
On Nexus One, Nexus S, Nexus S 4G, Xoom, and Galaxy Nexus, the bootloader is locked by default. With the device in fastboot mode, the bootloader is unlocked with
$ fastboot oem unlock
The procedure must be confirmed on-screen, and deletes the user data for privacy reasons. It only needs to be run once.
On Nexus One, the operation voids the warranty and is irreversible.
On Nexus S, Nexus S 4G, Xoom, and Galaxy Nexus, the bootloader can be locked back with
$ fastboot oem lock

I would love a way to root without unlocking the bootloader -- coming from the Nexus One, which I easily rooted without ever touching the bootloader -- it didn't occur to me that rooting would require unlocking the bootloader. Of course, I wish now that I'd unlocked the bootloader right when I took the phone out of the box, which is, I see now, what everyone recommends. But I've more data on the phone than I want to deal with losing right now.
So if anyone following this thread turns up a way to root without unlocking the bootloader, please let us know!

You won't see this feature arrive until manufacturers start selling ICS phones with locked bootloaders (I'm looking at you HTC, LG, etc). Devs will then try to punch a hole through the OS instead of using simple fastboot commands, as the bootloader will be locked down.
I don't understand why you would wait though, just fastboot oem unlock, root, then fastboot oem lock. The only way your warranty is going to be voided is if you have a rooted rom, that padlock means nothing on the Galaxy Nexus. IF THEY SEE SUPERUSER, THEY KNOW YOU ROOTED. They don't give a **** about the splash screen

Root question

From day 1 i wanted to root my nexus, i haven't just encase bugs and stuff. Is root worth risking warranty right now?

You can always flash back to stock and lock the bootloader if rooting didn't appeal to you.

What he said.
Also, rooting and adding ROMs can fix any potential bugs that your phone might have.
And, the sooner you unlock your bootloader, in order to root, the better because unlocking the bootloader erases all your memory. After that, you can back up everything and its all good.

I heard apple has a way to check if you ever jail broke something, it's a possibility that android phones have that too right? Sooooo just locking the bootloader and taking to stock might not get you a new phone right? Or have people not had any problems about returning a previously rooted phone?

if you unlock the bootloader there will be an unlock icon on the splash screen.

i dont think they can see if you rooted your phone. but if you unroot, and lock the bootloader, you will be fine.

Currently you can only do this via HTC see here. However, it will void some aspect of your warranty if later on you need to send it back for repair, as HTC keeps a record of the phone have been unlocked by them.
I'm waiting until some clever developers come up with another way so we can unlock it without going through HTC.

Check the sticky in the Development thread, there are already "How to" guides posted.

Although as Bigmille says, if you use the HTCdevelopers.com official method to unlock the bootloader, it's possible it may void your warranty, if HTC claim that any fault is caused by you loading unofficial software onto your phone. You should be fine for strictly hardware issues, though - as long as they can't claim they were caused by any software you loaded.
The official bootloader unlock leaves traces behind, so even if you re-lock your phone before returning it, they will know that you have unlocked it.
I'm hoping that we will have unofficial S-Off methods soon, so we can return the phone to factory state without the warranty being affected.

If I want to root, I need to unlock bootloader. But we should wait for the other S-OFF method, not use the HTCdevelopers.com official method. Is it right?

The choice is yours, really. Not sure if I'll wait or not, but for now I'm giving myself a few days with the phone before I decide, just to make sure I want to keep it. Though I think I will.
And I'm not sure how long I'll be able to wait before I root.

[Q] yakjuxw to jakju without unlocking the bootloader??

Hello,
A few days ago I got back my Galaxy nexus from O2 service and for some reason that I don't know they updated my phone from jakju to yakjuxw!!!
This makes my phone to be managed by samsung and not by google in terms of OTA updates.
Is there any way to switch back to jakju without the need of unlocking the bootloader? (this will void my warranty )
I've tried soft and hard reset but I couldn't get my phone into its's stock state.

Can you not unlock your boot loader change to yakju then relock it?

Exactly. I have no idea why people are worried about warranty. The Galaxy Nexus comes with a RE-LOCKABLE bootloader. You cannot tell the difference between a "never unlocked" bootloader, or a "unlocked and then re-locked" bootloader.

I didn't know that GN bootloader is re-lockable... warranty is always a good thing if you are able not to void it.

I agree warranty is a good thing. I never rooted my one x to preserve warranty I did to my s3 but the carphone warehouse never noticed the increased flash count when i returned it.

There is no flash counter on the GNex, and the bootloader, as mentioned, is re-lockable. The GNex is extremely easy to return to factory condition.

I switched from yajuux to yakju this morning for the first time ever, and I can confirm that the bootloader can be re locked with no problem. I also learn that you can even let it unlock until you need to send it for repair or exchange.

I can't tell if my phone is unlocked or not?

Ok, my phone was unlocked and rooted. I did the update for Verizon a while back. Lost root, but i'm not sure if I lost unlock. I'm getting a replacement from VZW and what makes me think that it is still unlocked is a padlock that is nearly locked but not all the way. This is on the black screen with Google above it, and not latter where you can slide it.
I did try searching, but I couldn't find something like this.
So, if it is unlocked I would follow this, right?:

and scroll to: Q. I want to send my phone back so I need to flash a stock rom and relock the bootloader?
Thank you!

Seems like the bootloader is unlocked, but it is not rooted. Btw root checker is telling me that it is unrooted also my wi-fi tether doesn't work any more. So, the guide above should work right?

Yes. It's unlocked or you wouldn't see the lock. Yes, before you send it back flash stock and relock.
