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...

Not really. You can flash a stock ROM and via ROM Manager - you just can't lock the bootloader...
Is anybody able to help, for some reason my wifi has stopped working all together, I have flashed different kernels, roms and have now just reflashed the stock google 4.0.2 image but it is still greyed out and just says turning wifi on when i try to turn it on....I have flashed the phone from the stock carrier image so am unsure if they will honor the warranty.
Thanks

If restoring the stock image didn't work, you should lock the bootloader and send it to Samsung repair service with warranty
It came with a branded rom when i brought it tho which would mean I have voided the warranty wouldnt it?

are you sure it was branded? i might be wrong, but there's no branded galaxy nexus. Maybe you just bought with a mobile provider, but it's not branded

ok, but it's still google Stock Image you downloaded from the official website right? I think that cannot invalidate your warranty, unlocking the bootloader does, having a yakju image doesn't
but they would know that flashing the google image requires unlocking the bootloader?

I don't think they'll act like *****es trying to avoid your warranty. But if you really want to be sure, just open a thread requesting yakjudv image; probably someone has it and can share it with you.
Same thing happend to me, in the end I flashed back to stock and relocked my bootloader contacted Negri Electronics and rma'd mine. I'm stuck using my old Dell Streak now while my baby is in the shop. Really sucks especially with AT&T doing all their throtling and such now I was worried that i'd get throtled because I couldnt use my wifi. Good luck to you man.
So um...I'm kind of shocked.
I just unlocked the bootloader on my shiny new USA GSM Galaxy Nexus from Google Play and...my data was still there when I rebooted. No Android Wizard or anything.
It's as if I did nothing, but I checked MULTIPLE times and I'm unlocked. Got the unlock icon during boot and everything.

Same thing happened to me. I was prepared to start all over, but doing the 4-in-1 from the Galaxy Nexus Toolkit, I was surprised to see the only changes were an unlock symbol appearing on the screen at bootup, and Google Wallet griping about my having an insecure phone.
I may re-lock the bootloader now that I've rooted. I'm not sure if I will lose root, but I only rooted to run an adblocker anyway.

Hmmm. You do have a shipping (sorry, "production") bootloader, not an engineering one. Very interesting... Not sure why some devices wipe while others will not, upon unlocking.

There are quite many security issues that could arise from being able to unlock the bootloader without wiping all data, for example, a hacker could get past your screen lock by:
1) Battery pull, then
2) Boot into bootloader using the key combination
3) fastboot oem unlock
4) Flash an unsecure boot.img that has r/w permissions
5) Edit the right files to remove screen lock
But I still have a feeling that this behavior with USA GSM Nexi is intended. Probably because Google intended that phone to be sold only to developers who are likely going to be unlocking bootloaders anyway, and decided to simplify the process?

I don't think the Amazon is a USA version but an international version. If international version it will have to be shipped overseas for repair, Google Play has USA warranty. Also if you do decide to root the USA version does not wipe your device during the unlocking of bootloader like the international versions do.

The USA version, as any other hspa+ version, DOES wipe userdata when unlocking the bootloader.
I have the USA version from the play store. My data wasn't wiped after unlocking the bootloader. Either way, its not a big deal. Warranty matters are much more important.

Nobody who has purchased a play store GN has reported wipe after unlock.
Mine from the play store did NOT wipe user data after unlocking. I am running CM9 and have locked and unlocked many times without wiping data.

Although it may be a bug that will be fixed in a later update so I don't know if the failure to wipe is a permanent feature. However, I can verify my GN didn't wipe either after unlocking.

I have 3 Play store Galaxy Nexus. They all wiped data when I unlocked bootloader. I think that's first hand experience. If it doesn't wipe the data, then that's a security risk.
Example: Just yesterday, I got tired of using CM9 and fastbooted the stock images without -w. I didn't want to go into recovery to wipe data and factory reset (because that just wipes data partition, not usb storage), so while in fastboot, I did fastboot oem lock then fastboot oem unlock. If it didn't wipe data, then my usb storage should've had a clockwordmod folder, music that I precache, and other various folders that were created from apps that were installed, and I wouldn't be introduced to the welcome screen upon bootup. Like I said, if it doesn't wipe data for you guys, then that's a security risk and you should be contacting Google. Because if you lose your phone, someone can oem unlock your phone and go through your data.

Well then your statement about "The USA version, as any other hspa+ version" is at least inaccurate. As you can see, many people's data did not wipe when they unlocked their bootloaders, so all phones/situations are not the same.
And I'm not really worried about someone unlocking my bootloader if I lose my phone - it's already unlocked If I had data that precious on my phone, I wouldn't root in the first place.

I was assuming that (maybe not the Docomo version) all GSM versions had the same hardware and if that's the case, then it's software related as to why your data's are not being wiped. Maybe the bootloader that came with the imm30d before it updated to imm76i doesn't wipe the data upon unlocking? Do me a favor, go into bootloader mode and tell me if your bootloader version is primela03.
I didn't get a chance to look at the bootloader versions when I received my Galaxy Nexus because I oem unlocked all three of them right away and fastbooted the latest takju images via flash-all.sh script on all of them just to avoid waiting for ota. I didn't want my dad and brother come to me and ask me "why is it telling me to update? What is it?"

Well sorry sir your wrong. At least I can say this for the first initial unlock and root using the Nexus tool kit. I have two of them and both of them did not wipe. When they booted up everything was the same as before I unlocked and rooted.
After reading some of the comments in the Tool Kit thread is is believed the USA version has a slightly different bootloader. Some think Google wanted to make it easier as they know people are going to root their phones.
There maybe other ways to unlock the bootloader which causes a wipe. But I can assure you using the tool kit doesn't.
I wont say that its not possible but I have read all the way through the play store gsm thread and not a single purchaser reported a wipe after unlock.

Yes, but after flashing the takju images for them, i loaded it up and did testing on the phone to make sure everything was okay. Afterwards, I would lock, unlock, and lock the bootloader again to wipe all data (including usb storage). How do I know it wipes? Because I am presented with the setup wizard again upon boot, and all the sample photos that I've taken to test the camera in the DCIM folder are gone.
Someone mention they unlocked bootloader and rooted with toolkit. For all those that did not have data wipe, which method did you guys use? I didn't use toolkit, I did it the old fashion way with setting up ADB. I'm use to doing that way since the G1 days.
edit: I'm not calling anyone a liars and this information about a no wipe bootloader unlock is all new to me. I'm just trying to find out why it's not wiping for some people...

So you have no way of knowing if your device was wiped the first time you unlocked, since you flashed factory images immediately afterwards. Could there be a difference between unlocking the first time and subsequent times? I wouldn't know because I only unlocked once.

Then there's a possibility that all GSM Galaxy Nexus doesn't wipe the first bootloader unlock. Maybe people didn't take notice the first time they did it. Just a theory.
Can anyone that relocked and unlocked the bootloader chime in and let us know if it wiped their data?
Dohctor maybe our play store versions are later revisions idk? All I know is I also have two galaxy nexuses from play store and when unlocking boot loader it did not erase the data that I had on my phone all of my apps were still there also. Obviously play store nexuses do not wipe data upon unlockingand who knows why. Anyways I will make a video to show the non believers I have no problem doing that.... I also relocked and unlocked boot loader because I tried starting dead fresh to get google wallet to work again let's just say that if u do not wipe or reset data inside the app your beat so I thought locking boot loader and unrooting then reflashing stock image would help. It didn't .... secure element is beat on my one device. So I unlocked the "relocked" boot loader ( this is what it says when u relock it) anyways it told me it would wipe data I proceeded. Rooted again threw touch recovery on booted into recovery and there was my aokp backup waiting for me ... so unlocked relocked and unlocked again...no data loss. Pretty cool I think of it as if u have data on your phone that is that important do not root then! So it not wiping data doesn't bother me. ....all using toolkit btw

Even if you don't root, people can get access to your data if it doesn't wipe upon unlocking the bootloader. For example; you lose or someone steals your phone and wants your data for some reason. You never unlocked or rooted your phone, it's bone stock. The thief will hook it up to his or her computer and unlock the bootloader and boot up clockwork recovery and pull all your data, including files and pictures in your usb storage (unless you enable encryption). I'm not paranoid, I telling you guys what's possible.
That sucks that relocking and unlocking the bootloader didn't wipe data for you. Don't have to make a video because I believe you. And about having a later version, that's not true. I ordered mines the first day Google made it available in the Play Store.
It sucks that Google Wallet still has that SE error. I always reset data within the app every time I switch roms. Glad my Wallet still works
Hello,
A few days ago I got back my Galaxy nexus from O2 service and for some reason that I don't know they updated my phone from jakju to yakjuxw!!!
This makes my phone to be managed by samsung and not by google in terms of OTA updates.
Is there any way to switch back to jakju without the need of unlocking the bootloader? (this will void my warranty )
I've tried soft and hard reset but I couldn't get my phone into its's stock state.
Can you not unlock your boot loader change to yakju then relock it?

Exactly. I have no idea why people are worried about warranty. The Galaxy Nexus comes with a RE-LOCKABLE bootloader. You cannot tell the difference between a "never unlocked" bootloader, or a "unlocked and then re-locked" bootloader.
I didn't know that GN bootloader is re-lockable... warranty is always a good thing if you are able not to void it.
I agree warranty is a good thing. I never rooted my one x to preserve warranty I did to my s3 but the carphone warehouse never noticed the increased flash count when i returned it.

There is no flash counter on the GNex, and the bootloader, as mentioned, is re-lockable. The GNex is extremely easy to return to factory condition.
I switched from yajuux to yakju this morning for the first time ever, and I can confirm that the bootloader can be re locked with no problem. I also learn that you can even let it unlock until you need to send it for repair or exchange.

I ended up getting the infamous bootloop problem in my LG G4 around 2-3 months ago. I disabled the big cores to gain access into my files and salvaged them from the phone. I thought that I'd send the phone back to RMA under warranty, but ended up using the phone as my daily driver as it didn't slow the phone so much that I couldn't manage the sluggishness. That grew up on me on friday, as I went and got an OP3 to replace my G4 and have it finally repaired.
I flashed a stock 5.1 back to the phone, and after restarting the phone the bootloop issue reappeared. As I had disabled the big cores, and flashed the stock ROM to it, can I assume that:
1) the phone is now back to stock with all the files I had in it deleted?
2) big cores are again enabled because of the stock ROM?
3) no signs of rooting as flashing a stock ROM will unroot the device?
1-) yes
2-)yes
3-) if you havent unlocked the bootloader, you can do a wipe and make sure.

If I remember correctly I did the rooting without unlocking the device and I used the stock V20d as ROM. But can't remember for 100% sure. How can I find out if it's locked or unlocked?
