[Q] Possible root without unlocking? - Samsung Galaxy Nexus

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 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

[Q] Can I re-lock the bootloader?

Hi all,
I just purchased a GSM Galaxy Nexus, and the seller didn't inform me that he had unlocked the bootloader. I am wondering if I can lock it, and return it to its stock settings.
Any input would be much appreciated.
Thanks,
Dave
fastboot oem lock
Just like he said, but if you want to keep your sdcard files, back it up first cause it will erase it.
Any specific reason why you want to re-lock your bootloader?
Just because it has an unlocked bootloader doesn't mean the software/firmware/recovery isn't stock necessarily. You can unlock and not change anything else about the phone.
If you EVER plan on rooting or flashing ROMs, just leave it unlocked.
I thought unlocking the Bootloader wiped the phone, not locking it....Anyways I too was given an unlocked bootloader when my phone was sent for repair. I would personally keep it that way as it has helped me try on a few things, namely testing different basebands without losing data & setup of the phone...
Leave it like that I'd say!
I would suggest locking it if you plan on doing anything remotely sensitive on your device, Google Wallet, corporate email, naked pics of your spouse, etc.

s1977 is correct. Locking the bootloader does NOT wipe anything. Unlocking wipes.

[Q] What's the benefit of relocking the bootloader?

Curious.....and I didn't see a thread about why some folks do so
none. its the same thing, just have it relocked when u send it in for warranty purposes + on stock
Like zephiK said: none. There is absolutely zero benefit to relocking the bootloader. On the contrary, there are many disadvantages:
if you ever have to unlock again, it will wipe your data
you cannot use most fastboot commands, which means that, unless you have root, you cannot flash radios, ROMs, backup your data, etc...
People relock their bootloader because, in my opinion, they are not very knowledgeable about how Nexus devices work, and have it in their head that, to be fully stock and receive/install OTA updates, you need to have a locked bootloader. Certainly not the case.
There was a guy on here who wanted to return his phone back to stock for warranty. His USB was broken. He could return everything to stock through the phone, except for locking the bootloader. If it was already locked, the problem wouldn't be there...
Not a good enough reason for me, but it could be a factor in your decision...

I still don't know if I believe that Samsung will not honor the warranty because the bootloader is unlocked, particularly on a device with a re-lockable bootloader.
As we know, HTC honored the warranty on the Nexus One, even though with an unlocked bootloader.

it's not so much the OEM, its more of the carrier.
vzw will not honor anything if the bootloader is unlocked.
Like I said, it's not a factor for me. I unlocked with about 10 minutes of my first full charge, and don't see any value switching back. Everyone is different though, so I thought I would just share this detail, no matter how trivial...

Help is needed urgently :(

There is a buyer for my Samsung Galaxy Nexus and he wants it asap, unlucky me i have the lock symbol on the display ( after unlocking bootloader and rooting ) can any one please help me in a way i can get rid of the lock symbol ??? and does the mobile remain rooted or root will be lost ??
I don't really see what you're asking... so are you referring to the the lock symbol on boot "open" or "closed"? Or a homescreen lockscreen?
And what do you want it to be? What do you want to do? Are you trying to restore to stock? You're not telling us.

That just means the bootloader is unlocked. Why do you want it locked again? It makes no difference to the experience. It just allows you to flash things via fastboot and/or hack the phone. Relocking the bootloader is a bad idea if you intend to ever unlock it again, because that completely wipes the device.
If the person you're selling it to wants the phone back to stock, just locking the bootloader DOES NOT DO THAT. You need to flash the Google Images and then relock the bootloader.

But if its rooted then just relocking the bootloader isn't going to help him get a warranty. Turning the phone in rooted is just as bad.
Restore it to stock then relock the bootloader. That's the only way he'll have his warranty.
Just flash the stock images and then the command "fastboot oem lock"
Warranty Accepted!
Changing ownership of the device voids the warranty with most carriers. (At least in the US). Do some research before you spin your wheels.

Should i check OEM unlocking option in the Developer settings ?

Ok so i have read many posts on XDA about bricked nexus 5x's and many others, sometimes the main probelm is the oem isnt unlocked. I myself have a Nexus 5x that is completely stock no custom recovery no root no nothing, i just update the phone, right now on Nougat 7.0 sep security update.
So my question is, should i check the OEM unlocking in the settings ? i will never install any recovery or root but i think by reading the posts, it seems like its a major problem if this is not checked, should i check it just to be safe ?

If you have issues in your current state they will most likely be hardware related and unfixable via software. But even locked you can completely reinstall the OS via sideloading an OTA or using the TOT method.
Enabling OEM unlock disables Factory Reset Protection (FRP). FRP is a security feature that prevents a stolen device from being activated. There is allot of info about it online if you wish to learn more.
So you need to decide if you want FRP or the ability to flash the factory images.

ok thx dude for the reply, nah i dont care about the FRP. so flashing factory images is easier right ? rather than sideloading or whatever this TOT method is...., and do most mobiles have a oem locked or unlocked ?

Sure, flashing the factory images is probably slightly easier than the other methods. Note that in your case you would need to actually unlock the bootloader to flash the images. With those added steps it's probably faster to sideload.
The Allow OEM unlock toggle has been around since LP I think. An pretty sure it's in phones that shipped with LP. It didn't automagically mean that the phones bootloader can be unlocked though. It should stop disable FRP though.

Yes, most, I think all OEMs leave the possibility to unlock the bootloader.
By default the bootloader is locked on most OEMs (Sony, Samsung, HTC, Motorola, even Nexus devices).
For Nexus devices it's a simple one liner to unlock/lock the bootloader which will also trigger a data wipe but. On Nexus devices it doesn't void your warranty.
For most other OEMs phones you have to follow some steps and usually get some kind of code in order to unlock the bootloader the first time. This will void your warranty!
If you don't know whether or not you should unlock/lock the bootloader, the answer is: NO!
It seems you're not modifying your phones software (Custom Kernel, Custom Rom, Root etc) and you seem to have no intention doing so. So it's not needed and even less "secure" than with locked bootloader. If you do, you should know that you have to unlock the bootloader in order to change the phones software.
Why would you want to unlock the bootloader when the only reason to do so is to modify the software and you do not plan to do this?
On a stock nexus there is no need to unlock the bootloader, you can even reflash your phone with locked bootloader with the stock software image.

That catch is if if you checked OEM unloking and chose to not perform oem unlock command now.
When something did went wrong afterward, you are able to perform oem unlock but it will wipe your data.
There is no point for doing it.

Should we unlock the Bootloader if no root planned

If you have no plans to root the phone is there any reason to unlock the bootloader?
It would probably break Safety net and Android pay. BUT if you're unlocked, you have ability to flash factory images. That could be beneficial something goes really bad and your device won't boot up. You're also less secure with it unlocked.

You can always lock and unlock the bootloader when you want.
I would say you should at least have the option checked on in the Developer settings.
So just in case something happened and you can't fully boot the phone. you can still get into it and unlock the bootloader and do what you need to do.
This happened to a friend of mine where something happened and couldn't fully boot and couldn't unlock bootloader cause the option was never checked.
I don't believe the unlock option stays enabled after it boots up.
I would argue why WOULDN'T you unlock the bootloader? Regardless of rooting, an unlocked bootloader is a safety net for when things go south. Phone decides to bootloop tomorrow? No big deal, flash the latest images via fastboot and start from scratch.
Sure there's the counter argument of the phone being much less secure and vulnerable in the hands of a person who is tech savvy and stole/found your device. I'm not worried about my phone being stolen so I ALWAYS unlock my bootloader.

Very true. If the phone goes into booploop due to a bad zip or whatever other reason you have a bricked device with no options to recover.
It's healthy for me to unlock my Bootloader ASAP on XDA!
Unlocking the bootloader was always the very first thing I did when I got a new phone. However, I use Android Pay all the time, and Google seems very determined to break AP for unlocked bootloaders with every new patch. Sure, someone usually finds a way to get it working again, but that sometimes takes time, and I simply use AP too much to deal with it. As long as AP won't work officially with an unlocked bootloader, mine stays locked unless I'm flashing an image, and even then, gets locked right after. Luckily, OTAs are posted by Google now, often at the same time as the Factory Images, so it hasn't really been an issue for me.

If you ever contemplate going onto the Verizon network, when you first boot up after placing VZN sim into the phone,
the ability to ever unlock again is eliminated. You could relock it, but it will have the Unlock option in Developer
Option greyed out forever after that. I would unlock it maybe because of Verizon thing, but also to be able to flash factory a image in case I ever mess up the phone.

As long as you have the Google version it should never grey out on you at least that's how it was with the first pixels. I have Verizon I've never had it grey out.
