New Galaxy Nexus owner

Hello all. Well after many many years with Sprint they finally got on my last nerve and now I am a new Verizon customer and a very happy new owner of the Galaxy Nexus. Awesome phone! Anyway my question is I have been told the bootloader of this phone is locked. I have never messed with a phone with a locked bootloader. While I was with Sprint I had the Epic 4G Touch so I am familiar with Odin, CWM, flashing roms, etc. What is the preferred method to altering the Nexus to be able to root, CWM, flash roms? Also what is currently considered by most to be the best rom that leaves the phone with all of its functions working? Thank you in advance for any information you folks can offer.

Unlock the boot loader firstly but beware it will wipe your sdcard.
Use fast boot to unlock it, type oem fastboot unlock and go from there.
Flash cwm using fastboot by typing fastboot flash recovery xxxxxxx.img (xxxxx.img is whatever the filename is)
You are probably familiar with cwm so I won't bother explaining that.
All the rooms here have everything working on them. We'll except sense 4.0 and touchwiz ports etc. But that's obvious.
Ps. All phones have locked bootloaders!

Yeah, you might mean unlocked bootloader. You do have to unlock it first, but it doesn't take an exploit to do so. See here for a starting point:

As for the best rom, impossible to say, so many . It depends on what exactly you're looking for. aokp is probably the most features-popular, but there are many others. I use cm9 with the reloaded mod, personally.
sent from my Zerg Hatchery.

Ok I used the Toolkit 5.5 to unlock, root, CWM etc. Seemed easy and effortless. I have now installed AOKP Rom on my Nexus. What do I need or need to know in order to return my phone to box stock say incase I have to take it to Verizon for any reason?

Forgive me, I am just an end user that can follow directions well Can you explain what this means? Is there a file I am going to have to download or does Option #8 in the Toolkit do everything?

Options 8 (Extract and Flash Google Factory Stock ROM), 10 (Reflash Stock Recovery [just to be safe]), and 11 (Relock bootloader) will return it all to stock. I know, because I just had to do this to 3 GNex's this past week to send them back to Verizon

Looks like your question was answered, but for me, I used Wugfreshes toolkit to root then to unroot, just click unroot, let it do its thing and then click OEM lock to make it factory.

Only if you are stock and rooted.
He is running a custom rom and kernel and has cwm flashed, that method will not revert them to stock.

My apologies, I totally forgot to update my signature. I do not have the GSII anymore.

Can anyone point me int he direction of the box stock rom file I need to work with Toolkit to restore my phone? I followed the directions and got the image from code.google.com but it wont install. ALways says something is missing.

Toolkit says the file shouls end in .tgz but the file I am downloading from Google does not say that. My phone is 4.0.2 (ICL53F) and that is the file I am downloading from Google's image site.

[Q] Need to do anything before unlocking bootloader?

I heard about Wallet not working if you unlock bootloader without logging in or something? Is that true? Is there anything I should do before I unlock my bootloader, root, and install custom roms?
Thanks.

Back up your sdcard to your computer, as unlocking will wipe that. As far as the Google Wallet question, I am not sure. I've never had an issue with it.

If you've been using your phone before your unlock the bootloader, then back up your "/mnt/sdcard" because it will be wiped when you unlock bootloader.

You must reset Google Wallet from within the apps settings. Open the app and go to settings>reset wallet. This MUST be done before you do a factory reset, unlock the bootloader, or flash a ROM otherwise you run the risk of breaking the NFC secure element for wallet.

So If I have had my Nexus for an entire day and I don't care if I lose anything, since there is nothing but a few apps I can get again, I can just go for it?
Should I wait until my Verizon Nexus upgrades itself to 4.0.4??

That's totally up to you. I personally ran mine stock for a month to make sure I didn't have any hardware issues. I'm in the process of backing up my SDcard right now so I can unlock and root.

Just unlock it now so you don't have to worry about backing up your sdcard later when you do unlock later.
You'll still get the OTA if your boot loader is unlocked.

Great, thank you very much!

[Q] Can you root without doing the CWM recovery?

All I want to be able to do is install and use Titanium Backup. Can this be done without the whole bootloader unlock / install CWM recovery / Flash SU method?
This is for a GSM GN from the Google Play store.

No. Not that know of exploits like that don't work anymore. But you can just unlock, flash a recovery, flash superuser. Then flash the stock recovery and relock the boot loader.

the only way you can do that is if you're on 4.0.2, but i would bet you are on 4.0.4

I would NOT recommend it either.
However, if he feels like he really has to re-lock, we now have a method that can unlock the bootloader without wiping, assuming you have root of course. (But if you ever lose root... you are screwed!
EDIT: I didn't realize that the OP had a Play Store device. Although I don't have one, the Play Store devices are said to NOT wipe when the bootloader is unlocked.

Thanks for the info. And just an FYI, my Play Store device does wipe data when I unlock the bootloader. Not a huge deal, but it does reset it to factory state.

some people have said it didnt wipe when they unlocked the bootloader when they got theirs from the playstore.
i always assume its going to wipe everything.

I had no idea that unlocking the bootloader would wipe everything, but I knew I had to unlock it first in order to root it so I could backup all my apps with Titanium Backup, so guess what happened..
The thing is, if I hadn't done that, I would have waited for the official Jelly Bean from Samsung for quite a while, for my yakjuxw variant...
Pfff. Everything about this whole affair with ROMs, rooting, backing up, seems so weird and counter-intuitive to me. I just don't understand it!

So Rooting it and re-locking the bootloader doesn't limit the root functionality right?
and is there a possibility of having root + CWM + Locked bootloader ?
will CWM work that way ?
Plus whats the procedure to unlock bootloader without wiping device if your device has root + locked bootloader?

Well my previous phone was an android which was never updated officially after eclair. Running Cm7 ports kinda lagged the phone which was pretty noticeable after 24 hours or so,
So i used to reboot it everyday to clear memory. and yeah, I guess old habits die hard and i just love the jellybean boot up animation, so no reason not to reboot it, and thanks a lot for your replies

then i'll go like "Nah, Why should i do that when i have the purest android ever and there's no need to mod this fast beast"
Long story cut short, i just wanna show off how awesome pure android is

[Q] Rolling back to 4.3

I've just upgraded to 4.4 here on my Nexus 7 which has broken Kingsoft office which I require for my work.
Whilst I wait for a fix from Kingsoft, is there any way to roll back to 4.3 without voiding my warranty?
Thanks in advance.

Try quick office. It's free and works fine.
If you still want to roll back, you can do without voiding warranty

also your bootloader needs to unlocked for it to work and you will lose your data if you unlock the bootloader now.
There might be better options though. Wait for someone more knowledgeable to reply.

You can rollback to 4.3 system software however if you try to keep your user data your system will hang at boot. If you have a backup of your 4.3 user data then that is not a big deal. Alternatively if you wipe data factory reset from recovery that will get things working again.
You do need to unlock your bootloader and flash the factory images though.

You need to have the bootloader unlocked to flash anything unsigned. Currently the only thing Google sends out that is signed are the OTAs. There is no OTA from KRT16S/O back to JSS15*, so your only option is to use a factory restore. Since the factory restores shipped so far are not signed, you need to unlock bootloader.
You can unlock the bootloader here:
http://forum.xda-developers.com/showthread.php?t=2379618
During the process of unlocking bootloader, the system will wipe your userdata and sdcard for security reasons.
The post you reference assumes your bootloader is already unlocked.

So, you got two options left.
You need to unlock the bootloader under both methods. Remember it wipes user data completely.
After unlocking you can either flash the factory image for 4.3 or use the one click factory restore.
Personally I feel one click factory restore is easier

Yes, but I may be mistaken but unlocking the boot loader may constitute as voiding the warranty as well.
You would have to unlock it, which will wipe, downgrade to 4.3, then relock it to make it look stock.

Thanks guys I'm back on 4.3. How do I re-lock the boot loader?

You can get back to the 4.3 ROM w/o wiping user data (as a result of the unlock)
However the 4.3 ROM will not boot (will hang at X animation) with your user data once the 4.4 upgrade process has completed on your user data, so you will probably end up wiping user data anyway to get the boot to complete.

Boot to bootloader (Power+VolDown)
in command prompt in your SDKs platform-tools directory
fastboot oem lock
Unlike unlocking, you will NOT have to wipe user data when locking.
Locking just sets a flag so it is very fast.

However, I would leave it unlocked if I were you and you are not selling it or getting warranty work done. If you ever need to unlock again you are going to be in the same boat of losing all of your data.

latest version is compatible with kitkat

Let me ask a question. I've got my bootloader unlocked and I've downloaded the stock 4.3.2 from the Google Developer's site. If I don't want to do the one click restore can someone point me in the right direction for a good step by step? I've looked at a couple of different ones but none looked right or I'm not reading things correctly. To be honest I can't find the one I read from a couple of days ago. It addresses dealing with the tarball you get when you download the image from Google, but I'm really really bad about not using bookmarks. So I'm kinda stuck at this point now. Thanks in advanced.

To use Google Pay, you need to pass Safety net.
It is not related to bootloader.
And relocking bootloader without losing any data is possible if and only if you did not flash any custom mods like recovery , kernel ..As it validates md5 checksum
