I've read that when unlocking the bootloader with "fastboot oem unlock" it sets s-off. Is possible to set it again to s-on for warranty purposes?
In the wikipedia says that:
Once the user accepts the terms the protocol is enabled and a security flag showing that the device has been unlocked is permanently set.

No, I still have the bootloader locked and would like to know before if is even possible.
Yes, fastboot oem lock will relock the bootloader.

And that is what preserves warranty? I mean, after installing official rom and relocking that's it?

Should be.
Depends, though. I returned my GNex with AOKP build twenty something, franco's kernel and what not.
S-on/s-off is only an htc thing I believe. Only htc phones have that from my understanding, not Samsung phones and especially no nexus phones regardless of manufacturer.

You refreshed my mind just right now. The s-on and s-off is a HTC thing, I saw it on htc subforums.
I've tested 'fastboot oem lock' and does relock the bootloader, provided that you have stock rom installed. So this will preserve warranty.
Thank you.

Well, you are half right. It is an HTC term and it refers to the NAND lock. Other manufacturers use locks as well -- Motorola being a prime example.
However, you are wrong about no Nexus devices being S-ON. The Nexus One is an S-ON device. Yes, it has an unlockable bootloader, but it is not relockable, and you did not have write (and in some cases, read) access to all the partitions.

On HTC devices, in order to get true S-OFF, you need a special SIM card, or SIM emulator to write directly to the NVRAM, which contains the security flag. Not sure on Motorola devices, as I don't believe anyone has figured it out yet.
On HTC devices, using the "oem" qualifier after "fastboot" gives you access to a huge list of other fastboot commands, but only with an engineering bootloader flashed. Some examples: dumping partitions straight from fastboot, flashing partitions not normally written to, etc.
On the Galaxy Nexus (using a shipping bootloader), it seems that the only "oem" commands available to us are lock and unlock.

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.

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.

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
I bought my Galaxy Nexus at a VZW Premium Retailer a few days ago. I noticed right away that in the settings it was listed as an "Engineering" model. I have the white unlocked icon on bootup, and in the fastboot menu I have
PRODUCT NAME - tuna
VARIANT -toro
HW VERSION - 9
BOOTLOADER VERSION - PRIMEKK15
BROADBAND VERSION - 115. EK02 CDMA - 1515.EK05
CARRIER INFO - NONE
SIGNING -engineering
LOCK STATE - UNLOCKED
Does this change anything in the way it will be supported? Will it get updates sooner? Later? Not at all?
Also, if I were to go about rooting the phone, do I just skip the part in the guides that talks about unlocking it, or is there another procedure that I have to follow?
I wanna say mine said locked when I bought mine. Not to sure. Let some more members ring in before tinkering with it.

Hardware rev 9 is the same as the release VZW Gnex, so it should make no difference that it's an engineering model. It should run either release or dev key builds without issue. Some of the earlier hardware revisions can't run stock builds.
It is possible that you could get dev builds pushed to your device from Google, but that depends on whether the IMEI is registered to Google as a test device and where it is in the queue to receive updates.
You could try *#*#CHECKIN#*#* from the dialer to check in with Google servers.

I don't see why people are that excited about the bootloader...
On a phone that doesnt allow you to unlock the bootloader, a bootloader that will allow unsigned ROMs is amazing.
Considering it's easier / just as easy to unlock the bootloader as it would be to install another bootloader, I'm thinking this isn't that big of a deal to dump.

Although I have limited experience with Samsung (as the GN is my first Samsung device), I can tell you, for certain, that on HTC devices, having an engineering bootloader gives you access to a multitude of additional commands, which are accessed by adding "oem" after "fastboot". For a list of the commands (on HTC devices with an engineering bootloader flashed), you type fastboot oem ? and you will see the list. Here is the list on the Nexus One.
The issue that we had with the Nexus One was trying to get the dumped engineering bootloader to flash on a device with a shipping bootloader. The shipping bootloader would not allow an engineering bootloader to overwrite it, but xda member dla5244 created an exploit to allow flashing, and we managed to do it. See here. If the same issue arises with Samsung devices, maybe it could be packaged to be flashed with odin. Who knows. But it would be nice to have a dump so that people can mess around with it.
Hello there,
since 4.0.4 wasn't coming to my phone, I've flashed the stock image from google on my GNexus. I was wondering if, having unlocked and re-locked the bootloader, my warranty is void, or if it is back on.
Thanks in advance
Doesn't rooting already void ur warranty?
Sent from my X8 using xda premium
As long as you put stock from and relock bootloader, no one can tell you've done anything to your phone or voided your warranty.
Just like an iPhone jailbreaking voids your warranty until you restore it back to official firmware.
Galaxy Nexus GSM
You can always return to stock and lock the bootloader. No one will be able to tell you've done anything to the phone at that point.
I send my SGN in for repair after reflashing the stock image and relocking the bootloader. And there were no complaints that my warranty is void. So I asume there is no flash counter like on the SGS2.
Alright! Great to hear
Thanks a lot for all the replies =)
Oh, that's great to hear!
I have a similar question...If you were to be lazy and not relock the bootloader, would the people at a local VZW really know? I mean, in the past, I have seen people take rooted and Rom'd HTC phones to sprint and easily gotten replacements.

They probably wouldn't know... but how the hell lazy are you? Connect the phone to a PC and type "fastboot oem lock" into the command window. There's absolutely no reason not to lock the bootloader before sending it back in.

if they have 1/2 a brain, yes they can tell the bootloader is unlocked... since there's a picture of a unlocked lock.
As I wrote before I send my phone in for repair and relocked it before. Today I got my phone back and when I turned it on it was unlocked. I think they don't care about unlocked bootloaders as long as the issue is not caused by onlocking the bootloader.
They should be able to tell whether ur bootloader is locked. It changes one of the codes. For my w8 it changes Rxxxxxx (locked) to rxxxxxx( unlocked) so as long as they check ur warranty is as good as dead

You never have to wait to unlock the bootloader on a Nexus device.
You can unlock it by simply enabling usb debugging in developer options (and enabling oem unlock option if present) then boot to fastboot and do a fastboot oem unlock in a command prompt. Follow the on screen prompt and you will be bootloader unlocked (your system will be wiped).
If you got a bit lost by those instructions you can use my android toolkit to do everything automatically *HERE*.

What turned me away from the nexus 5 before was the battery drain people kept complaining about. I wish I just went ahead and bought one, I'd probably still be using it instead of trying out all those phones...especially the ones with touchcrap ui :crying: After owning 5.5+ inch phones, I've realized phablets aren't for me.

Well if you received an unlocked code from htcdev, they will be able to tell you unlocked it, so I'm not sure how much it matters. Also, even if they didn't check the htcdev database, when you relock, your bootloader will show "relocked" instead of "locked".
I'm not sure what their return policy is on unlocked devices. Good luck.
Oh, and if you want to relock it, just go to download mode and enter "fastboot oem lock" in a command window.

If you want to relock your bootloader for warrenty, you'll have to S-OFF first and use some device-specific procedure(which hasn't released yet) to make it completely stock-like again.
