Lock Bootloader Without Root Access - Samsung Galaxy Nexus

So, my USB port burnt out on my GSM Galaxy Nexus, literally. My phone was rooted and had bootloader unlocked, so I was thinking of restoring everything to stock and send it back to Google. Here I am, being a dumbass, decides to flash back to stock ice cream sandwich with mobile odin and update to 4.1.2 thinking it would unroot and relock the device for me. I was real wrong, didn't realize that it only unrooted my device and relocking the bootloader require root access. So, any idea on how I can lock my bootloader again?

Since you don't have root I'm pretty sure you need a usb port that works to relock the bootloader

Yep.
Though I doubt they'd even care.
Should have locked first...and THEN Odin.

I had my phone rooted and boot loader unlock since launch of the device, back in November. Haven't done anything to it since now, which made me forgot certain things. Was reading information through several guide/post on how to return the Galaxy Nexus back to stock without using the USB port. Most of them were gear towards the Verizon version and none of them mention that locking the bootloader was required during root. Just did not realize that locking the bootloader requires root access. Guess that's what caused me not pay attention to the issue.... I know, it's my fault.
It would be nice if someone can point me to a solution. So, let me rephrase my question a bit. Is there anything I can do to get root access or lock the bootloader again without using the USB port? I have a Windows machine, Mac, and a extra Galaxy Nexus lying around. I can transfer files wirelessly, but no physical connection.

There are no root exploits for 4.1.2, afaik.
I think you're pretty much without options at this point, although like stated before, i doubt service will care if bootloader is unlocked.

Oh well, guess there's no hope of me locking it up without the usage of the USB port. Any words on anyone successfully getting their repair/replacement done even though they've sent phones in with an unlock bootloader?

[Q] Root vs Bootloader Unlock

I am pretty sure this has been asked/mentioned before, but to be honest, I really dont feel like looking through/over hundreds of posts and comments trying to get a true solid answer.
My question is, plain and simple. What is/are the major differences between rooting the Galaxy Nexus version 4.0.2 Android and unlocking the bootloader on it ?
I have been searching and so far it looks or sounds like you need to do one before the other, one of them is good for restoring files or something, etc. I have also read that if you are just trying to get the 4.0.4 Android update without having to wait on Verizon stupidity, I can unlock the bootloader, flash the update (or whatever its called) and it will be as if my GNex is rooted, but when I reboot it, it will be stock with all the new stuff that comes with the update, anybody know if this is true or not ?
Unlocking the bootloader just gives you access to the utilities like fastboot that let you root and ROM your device. It removes the "security" that gets in the way of hooking up the phone to a computer and having full control.
Rooting is the process of giving yourself "superuser" (think of it like Administrator) access on the device. Rooting itself doesn't do anything for you, its more about giving apps you install more control of the device.
If you unlock the bootloader to flash an update, you are not rooting your device. You're just flashing a file.
Rooting and unlocking are often confused because on many phones, they're both in the same process and you rarely do one without the other. Usually "rooting" is a catch-all word for modifying your device and changing the software.
Rooting allows you to customize your os. It gives you root access (ie access to everything). To root the nexus you must unlock the bootloader.

Any reason NOT to root brand new GNEX?

I'm receiving a new Galaxy Nexus in the mail today. I'm new to the Android world but this site has been extremely helpful in explaining the capabilitys of this OS. Since I've never used Android I don't completely understand the pros/cons to rooting my device. A lot of posts say "you have to do it to understand the benefits" or something of that nature. I understand that once you root you can change your ROM, kernel, navigate all file folders, use certain apps that require superuser access, etc. As of now, I'm not sure I'd want to do any of that. I may want to in the future when I see some limitations that could be bypassed by rooting, but for now I would like to keep the stock ROM, kernel, etc.
It's possible to keep everything stock when rooted, correct? So it would function the same as a stock device but would have the potential to be modified later. If an updated Android OS version is released, can I download and install it the same as anyone with an unrooted stock device?
Is there any disadvantage to rooting? Why would anyone NOT root their device? I'm just thinking that if I'd do it eventually, I might as well do it right now when there are no valuable files/apps/etc. that I'd have to worry about backing up.
People often root to flash aosp roms otherwise not available on htc or galaxy s phones
Aosp also in many cases gave better battery life than their skinned cousins
But on nexus phones and jelly bean I don't see much of one other than to experiment or to use addons like roms such as codename android and baked bean give

The main reason I root is for Titanium Backup. That is probably the only way to migrate apps (with data) from one device to another.
Also nandroid (Clockworkmod Recovery) backup is useful if you want to experiment with different ROMs and can restore stock and apps easily.
On a side note: Don't like CWM 6 when backup creates a huge BLOB directory structure. Not convenient to backup your backup to PC.
Backups
Free Tethering
Block ads
etc
Tethering is enabled already. Ah u probably must be talking about the us version. I have the international one.

I root for Paranoid Android and Titanium Backup. Two things I can't be without once getting used to them.
But really. Installing Titanium Backup almost feels like a necessity on Any phone to freeze/backup apps detach them from market etc.
I appreciate the responses but you guys aren't really answering my questions...

Yes you can be stock & rooted. Root by itself will not affect an OTA. The only reason to root is if YOU gain something. If your phone dose everything you want without root then there is no reason to root.

Yes u can stay stock and rooted.
If u root and take an update you will most likely loose root or you will have to unroot before u can take the update. One of the 2.
Biggest disadvantage is that it voids warranty. But no big deal if u no how to go back to stock.
People that don't root probably don't because they don't how, are scared to and/or they don't want to void that precious warranty.

1. Yes
2. Yes. Though root disappears if you update officially OTA. So then you need to re-root. If you would also unlock bootloader and install CWM you can not update OTA.
3. Umm. I guess some manufacturers claims that warranty is void when rooting. That's pretty much the only not-to reason I can think of. If rooted only and don't "use it" you won't even notice you're rooted.

It's unlocking the bootlaoder (fastbbot oem unlock) that will (not Play Store devices) wipe the device, not rooting (though the easiest way to root is to unlock the bootloader).
Ok I think its becoming more clear now.
I ordered mine unlocked from the Play Store. Does that mean the bootloader is already unlocked?
How often does an OTA come out anyway?

No, that refers to SIM unlocked, not tied to a specific carrier.
[REF] efrant's "Android for Galaxy Nexus" 101 & FAQs
If your new to Android this is a good place to start getting acquainted with the terminoligy & procedures
Right, I know it is carrier unlocked. So a Play Store GNEX still has a locked bootloader but unlocking it does not erase your files...
If that's the case I guess there's no downside to waiting until I see a good reason to unlock and root. I was thinking that I should do this on my brand new phone so that it wouldn't have any files on it that I'd need to backup. It sounds like I wouldn't have to worry about backing up regardless.
The only reason I can think of to unlock the bootloader straight away (& it's arguably a good one) ...
If for some reason your phone won't boot into android you could fastboot boot a custom recovery & have adb access to pull files from the virtual sdcard.
Rooting is the best thing to happen to Android phones. Do it.

Yes it will. Unlocking the bootloader via fastboot oem unlock will erase /sdcard. Does not matter if you get if from the play store or not. But like you said, if the device is brand new it doesn't matter anyway.
Side note: recently an exploit is discovered that allows to gain root without unlocking the bootloader. And if you have root, you can unlock/lock the bootloader at will without losing data. Follow the link in my signature for more info.

[DISCUSSION] Google Play Nexus not wiping after Bootloader Unlock

[Q] Bootloader. Locked or Unlocked?

So my family is about to switch to AT&T from Boost Mobile. And I think I am getting a Galaxy S3 from them. And I would love to root and install CM in it. But I have been hearing reports of AT&T's locked bootloader policy and such. Should I worry about it for the S3? Or does it still have an unlocked bootloader? If it doesn't, should. I unlock it first, then root? Or root first? Please reply, and if you do, thanks,

if your phone firmware is higher then 4.1.2 then
check if your phone is locked or not Dial *#7465625# into your phone, a screen will pop up telling you what is on.
if Network lock is ON that mean your phone is locked and for now there is no way to unlock your phone for free (you have to pay for unlocking)
if your phone firmware version is 4.1.2 or lower then that then
go this link and find how to unlock your phone for free http://forum.xda-developers.com/showthread.php?t=2529200

The bootloader issues should not be insurmountable. Being a new phone I expect it will come with the 4.3 version of Jelly Bean installed. This will be the first thing to check once you have the phone. If it has 4.3, it will have Knox installed and this will need to be turned off to install a custom ROM. All I have seen regarding removing Knox is either after or at the same time you are rooting. To root, the CF-Auto-Root method works for many. Both the CF-Auto-Root and a second method are here This thread also links to a script which will remove Knox, if needed.
You will need to decide which version of CM you wish to install, probably 10.2 or 11. At this time the 4.3 bootloader will work with both. I would recommend reading about all of this, and having a fair understanding, before doing anything to your phone. I won't hurt to run it on stock for a week or two.
Some things to bear in mind: The phone may come with the 4.1.2 version of Jelly Bean, but I doubt it. If it does you will have to update the bootloader before proceeding, more reading because there is an option involved - the official 4.3 bootloader (MJB) or the leaked 4.3 bootloader (MJ2). There is a bit of a chance the phone could come with Android 4.4, KitKat. It all depends on the timing of when you get your phone, when AT&T rolls out the update, and if the store personnel update the phone giving that 4.4 is available. If it does come with 4.4, DO NOT change anything until those on here that do the good things for our phones understand how it behaves.
Remember all of the warnings about anything you do being your responsibility.

[Q] P605V - unlock bootloader

So the Verizon version bootloader is locked. From what I understand, that means that I can't root it. Is there any attempt to unlock it? Or work around the lock? Do any developers actually have one of these? Should I return it and get the international version? My issue is the warranty (I tend to break stuff) and the speed and coverage of Verizon's LTE network . I am missing titanium backup, overclocking, etc.
Thanks for any info.

Unlocking the bootloader and rooting are mutually exclusive. A device can be rooted without being able to unlock the bootloader.
In fact, I've found myself in the odd position once on my Tab 10.1 of replacing the bootloader and not having root access. It was easy to fix but I found that an odd spot to be in.
I can't use Odin to root it. Is there another way available?
Sent from my SM-P605V using Tapatalk
me too
I'm sure someone will come out with a root for it eventually but, who knows when. It just came out on Verizon a couple weeks ago. Srsroot says it works but, I didn't have any luck. It just rebooted a couple of times said it was rooting and did nothing. Kinda wonder if it was just a scam to get my info. Don't have anything on it yet though.
[BOUNTY] Unlocked Bootloader for P605V
I am going to offer all of our development $30 to whomever can get a working unlocked bootloader for the Verizon 4GLTE P605V Samsung Galaxy 10.1 2014 edition. It's complete nonsense that going as far back as this post (April) that there isn't a solution....
You can root 605v with towel root.. Just rooted mine. Can't install custom recovery. But things like xposed modules works fine. Ad away works.
I think TowelRoot works on 4.4.2, and according to a Tweet and their webpage, SRSRoot works on the SM-P605v 4.3 and 4.4.2. My previously rooted P605v's screen died and I'm getting a replacement sent (I didn't want a newer tablet without the stylus). I hope that whatever OS version is on it is rootable!

Any way to secure a rooted phone? Does root break things?

I am considering this phone as a replacement for Note 7, so I have some questions about root.
Does it break Android Pay, and if so, is it permanent? Like does it fry "secure element?" Or can one root, install adblock .hosts, but then reverse the effect?
Also, if the phone is rooted, can it still be secured? So, if I lose my phone, can someone plug it into usb and flash/wipe data? Or can it be secured, so that it could only be tampered by the owner?
Thanks.

Gentle bump.
At the current moment there's currently no root yet (although Chainfire did got seamless root working with boot image mods but is still working on getting everything done) and there's currently no custom recovery.
Also, Google hasn't used SE for the longest time since Verizon and other carriers has been locking out that chip on the SIM card for a long time. Instead they do some sort of emulation of sort which is stored in the data encrypted so if you ever wipe your phone you don't have to worry about the SE being all jacked up without unregistering it first.
In terms of being able to use Android Pay, it does check to see if the bootloader is unlocked but there's already a kernel out that bypasses that check and I'm able to use it just fine so even if you are rooted I'm sure you could just use that kernel and it'll still work (I'm not able to test with root since the root isn't publicly available yet but usually you can go into SuperSU and tell it to hide su and android pay should still work if it does check to see if su is installed on top of the bootloader being unlocked). So there's always ways around it.
