Quick question

Is it possible to unlock the bootloader/root the GN on the stock rom, I know this can be done, however, will it cause any problems without a custom rom?

Yes it is possible. No it will not cause problems.

It will wipe your phone.
Sdcard partition too.

It'll wipe your phone, and if you change anything more than just rooting, you can't automatically update with an OTA.

So I'll need to reflash the stock rom? From my understanding only user data gets deleted.

No your rom will be fine and yes its just user data, ALL user data.
Photos music etc!
But ya the rom will be fine!!

Since there's no 'SDCard' on the GNex, all your user data + pics + files + anything non-ROM will be wiped. What you will get after bootloader unlock will be the same as when you first turned your phone on.
Of course, this is IF you didn't buy your phone off Google Play. There are rumors that Google Play phones don't delete user data when bootloader unlocked.
Either way, here are the steps:
(1) use an exploit to root the phone without unlocking the bootloader
(2) use backup tools to save your apps + data + user data off the phone
(3) unlock the bootloader
(4) root the phone (again, with the same exploit in step 1)
(5) restore your phone from the backups you made in step 2
*NOTE* - you will still get OTA updates even after you've done the above steps, but you will probably lose root after each OTA update and will have to wait for a new exploit, if any, before you can root again.

Ahh..I see.
So once I'm rooted and do the OTA updates....does the root stay? Or I have to re-root it?

You have to re-root or use OTA root keeper from the play store.

doesnt work on 4.0.4, only 4.0.2 i believe.

Wipe happens when you unlock your bootloader (which you have to do to flash root), and you can't unlock without wiping.

You can back up your stuff via adb, unlock (wipe), and then restore via adb. It'll take a while, but it will be like it was never wiped.

As was mentioned before:
a) if you are on 4.0.2 or 4.0.1, follow the instructions here to root. Then you can flash CWM, backup via that, and then unlock your bootloader.
b) if you are 4.0.4, follow the instructions here to backup, then unlock your bootloader by following the instructions here (you do not need to do steps 5-13 under part D if you only want to unlock your bootloader), and root by following part E in the same post.

Should I relock bootloader after root?

I have unlocked my gnex and rooted it.And then should I relock it?is there any difference whether relock it or not?thanks in advance

No difference just keep it open because if you ever have to reflash recovery or something you'll have to re unlock and that will wipe all data.

The Play Store bought Galaxy Nexus doesn't even wipe when unlocking the bootloader, so there is no reason to bother relocking if that's what you have.

Agreed, but multiple users have reported this. I'm rather curious what's going on with those play store devices. It's hard to believe Google deliberately removed a crucial security feature. If unlocking the bootloader does not wipe userdata, everybody who's not using encryption is basically facing a security risk.

I was unaware, haven't been following the GNex forums for awhile. Seems like this could be a security issue...

My purpose to root is limited to supersu on the stock rom and xposed framework if possible. I do not want to flash any custom rom.
Is it possible to keep all DRM related functionalities with stock rom + root, with this method?

Will I be able to apply/receive software updates when root enabled?

Will I be able to apply/receive software updates when root enabled? I am worried that I won't be able to apply google updates once root enable, is this an issue? Is there a workaround?
Thanks!

If you install the simple fix here:

You can install future OTAs successfully and keep root.

Just rooting doesn't prevent updates. You just lose root and have to reapply after update.
Custom recovery means you probably need to download the update file and apply it via the recovery instead of the automatic updater.
Changing or removing system files will almost definitely prevent updates being applied.

Actually I was surprised also, but SuperSU does prevent the OTA from completing successfully.

I JUST did this. I had TWRP and rooted. I has 15J. Booted my nandroid. Downloaded the 15Q update, restarted to install. TWRP caught the stock image and flashed it.
Then I booted into 15Q. I lost root and TWRP. Flashed over TWRP through fastboot and rooted.
No issues.

Are you rooted using SuperSU, what version, and can I examine the zip file.

Thanks guys, actually I haven't rooted this device yet. Because I am still reading on stuff here on xda how to do it the right way and the links you posted

hi sfhub, do I need to do
fastboot oem unlock
before doing
fastboot boot twrp.img ?

I've been rooted since day one and gotten ota updates fine.
I use twrp and just make sure to flash supersu each time and call it good. Not a single problem on my end.
Even still if you bork it just flash factory image. It's pretty simple to get out of a pinch. But rooting and ota should work fine as long as you keep stock image. Just reflash supersu each time and you're good to go.

If you aren't already unlocked then, yes.
Most people will already be unlocked though if they are rooted.
fastboot oem unlock process will force a factory reset for security purposes so backup anything important.

I haven't rooted my device yet , I am on all stock. Does 'fastboot boot' just loads the twrp image and not flash it?
How will I be able to backup stuff, are there any other options aside from titanium backup that requires root .

There are some backup apps that don't need root, but probably need to restore.
You can also try adb backup, but it may not backup 100% of your stuff.
I'm not the best person to ask on the backup as I always unlock before I do most of the software installs just so I can avoid losing customizations later on.

Thanks, I am currently backing up using adb., a non 100% backup is better than no backup at all. I hate redoing things.

Yes, very simple, just type
fastboot oem lock
I would advise against doing so unless you plan to return the unit though, as if you ever need to do stuff to your system (even factory restore) then you'd need to unlock again, which would factory reset again.

The 1.55 update doesn't appear to want to install properly for me from Google Play. Is this an issue of having the OTA fix installed?
Nevermind...i guess i needed to reboot...but, this does beg the question, is there anything related to the OTA fix that needs to be "uninstalled" in general?

Bad idea. Next update might fail from left over stuff from root or a mod...then you are done.

The solution (I think) would be to wipe data and flash the entire stock image for your phone, then re-lock the bootloader. This will make sure that any folders/files pertaining to being rooted are gone and shouldn't cause any problems when it comes to validating your OS. Just make sure you properly unrooted SU by using their uninstaller/unroot tool before wiping and reflashing.

Flash. all to both slots and be sure to include -w

Out of curiosity, why do you even wish to lock the bootloader? Especially with the numerous horror stories of users unable to resurrect a bootlooping device (rather simple to fix if unlocked) because their bootloader is locked.

Just an FYI, here's someone that locked their bl. Only 2 reasons I can see this as necessary is RMA, and Android pay. And Android pay works with magisk, so really only one reason.
