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
I unlocked my bootloader several months ago, but now my SIM card readers (both of them) have gone out. I have no idea how, no water damage or anything like that has happened. They just stopped working. So I went complete stock firmware, locked bootloader, everything but I am still unable to take OTA updates like a new phone would be able to. I think this is because they banned my device from OTAs which I believe they do if you have messed with the device. I need to RMA my device so my question is would it be better to say that I didn't tamper with the device and run the risk of them finding out I did, which is pretty likely seeing as how my device has been banned from OTA updates, or tell them that I did unlock it and all of that but that I have relocked it and I am back to stock? If any of you have had a similar issue how did ASUS handle that? Thanks!

Since I am a new user I cannot post links. But Google "Zenfone 2 bootloader unlock" and I followed the instructions of Grekky's Blog.
there is no such thing as relocking the bootloader. only thing you can do it flash the stock image to make it look stock (since an unlocked bootloader has a white splash screen) but im sure asus knows of this and will still check and see that the bootloader is indeed unlocked and not warranty it.
This is just something we all accepted as a consequence of unlocking our bootloaders. hell i have a screen thats getting worse and worse with a yellow/brownish line coming from the top of the phone, but alas i have an unlocked phone too.
You can replace the white splash screen by flashing a black splash screen image to try and cover up unlocking your bootloader. http://forum.xda-developers.com/zenfone2/themes-apps/551-black-white-splashscreen-twrp-flash-t3141945 . If the reseller has no clue about custom recoveries and trying to flash a rom you'll be safe.
They fixed it, no questions asked. And yes, I was able to relock the bootloader.
I thought I've had this device nearly 2 years now so time to unlock and root as the custom ROMs are looking great.
But if I go on Sony page and enter my details to unlock my bootloader it informs me my device is not unlockable.
What are my other options?
Simply means your device is not unlockable. That's it. I'm guessing you got this through a phone carrier.
Yep through Vodafone, so is there no other option
Nope. It's done. Bootloader can't be unlocked at all. Even if you try to unlock bootloader anyway using flashtool, it will ask you to enter unlock key, which you can obtain only through sony website.
Thanks for your help maybe I should just upgrade to a new phone then only reason kept it stock was for warranty
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.

Yes, it does. That's why you should unlock or lock the bootloader when flashing factory images.

I don't understand what you mean by this.
You have to unlock the bootloader to flash a factory image and you can eliminate the w flag so that flashing the factory image won't wipe the phone.

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.

This. Android Pay is pretty convenient and I always told myself I didn't need it compared to unlock+root. Wish Google would allow AP with unlocked bootloader but I can understand why they don't from a security standpoint.

When you unlock the bootloader, phone is wiped automatically.
Deear All,
I just bought my z2 force (t-mobile) from internet. It is an unlocked version and i can use it with my own sim card. However, i found that it cannot update via OTA as the bootloader is unlocked. I have heard that after i re-flash the firmware, the bootloader will be relocked. I am wondering, will the flashing re-activate the carrier lock?
Also, is it correct that after I flash via Lenovo Moto Smart Assistant. the bootloader will be locked again?
Is there other method to allow the phone to get OTA again?
Thanks a lot for your help.

Unlocked bootloder won't stop an ota, but a custom logo.bin will. Chances are that the seller has also flashed a logo. When you boot you should see a warning about your bootloader being unlocked, if you don't and you just see a moto logo (or any stationary image really) then you have a custom logo which will fail otas. The easiest way to remedy this is to follow Uzephi's "How to Return to Stock' thread. Then you should get otas again. It is advised never to relock your bootloader. A good example of why would be that you have a custom logo, you relock, your phone fails to boot and you can't flash anything because you locked it. There is no real valid reason to relock your phone. As for losing carrier unlock, you shouldn't, those are usually permanent. Unless it was some hack which I doubt since I believe that is only for Spring variants. Just follow Uzephi's guide and you should be back to good.
