Devs, please move to appropriate category if i posted in wrong spot.
I was wondering if anyone knew how to un root and lock the bootloader back on the unlocked gsm version of the galaxy nexus? Rooted and unlocked for a buddy and now he is returning the phone. As easy as it was to unlock, i was wondering if it's close to the same command to lock? (switching unlock to lock) if so, then it would just be the matter of unrooting it. Any help would be greatly appreciated. Thanks in advance.

It is that easy. Format his phone then connect your phone in fastboot mode and type fastboot oem lock. That's it

Yeah, i think i understand. I should have read a little more (i also should've known better to do that first.lol) From my understanding i can flash the stock image to unroot, and then just fastboot command to lock the bootloader down. Right?
Correct

I was reading some info on the Galaxy Nexus being released on Verizon today. One article talked about unlocking the bootloader right away. I was wondering if this is necessary/recommended/even possible on my E4GT?
If someone could explain an unlocked bootloader, I'd sure appreciate it.

honestly you should check out the stickies and the wiki for our phone for all the info you will ever need but there is no need to unlock bootloader when rooting our phones... Like I said check out the wiki for our phone and you will find all you need
Straight from the factory, the bootloader on this phone is not locked. This is a good feature from Samsung from the standpoint of a XDA user.
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

What do you mean by unlock? the phone came unlocked?
E.G. when you turn on the device, where it says "Google" is there a unlocked lock present? if there is... then no, you need to flash Clockwork Recovery (ROM manager via market or download img and fastboot flash it)
If it was already unlocked then you wouldn't have too but your going to be in ADB anyways mine as well run the unlock command to make sure. If you need any help please ask
Thanks for the quick reply.
Yes when power on . The google logo is on the screen. ( beside the sales ref told this phone was unlocked )

The Google logo is always there. What you're looking for is a lock icon near the bottom on the Google screen. If you're bootloader is locked the lock icon will not be present

The op probably mistakenly thought unlocked phone via network. I would just day goto the stickied post and do all of the steps as I have no idea why someone would be selling a phone that came used and void the warranty without a customers content.

Hi,
I have to send my GSM GNex for repairs and its still under warranty. Though I have it rooted and unlocked, I would like to know how can I restore stock so that I could send it back for repairs?
Also, there is no permanent lock, right? Because if I want to root and unlock it later, I should be able to, right?
I believe the Nexus Root Toolkit has this option so I will probably use that. But my big concern was that it should be able to be rooted and unlocked later if need be?
Thanks in advance for your help.
Yes, we can unlock and relock bootloader at will.
READ the stickies, especially this one. Don't use a toolkit.

Using an unlock code is not risky at all. In fact using galaxsim unlock is riskier although I have used it with no issues at all. Galaxsim needs root access and don't forget to back up your EFS folder if you decide to use it.

Roll back to 4.1.1, unlock for free using instructions on here, then flash to 4.1.2.
You will need to carry out full EFS backup, then get Samsung usb drivers, and ODIN, download 4.1.1 stock image, flash, factory reset and clear cache, then carry out the unlock procedure found in these forums, then download and flash your choice of stock 4.1.2 rom, and bingo, unlocked and updated phone.
