Flashing official Jelly Bean factory image - Samsung Galaxy Nexus

I own a GNex from Vodaphone Spain and all I want to do is network unlock it but keep it as close to factory status as possible. If I flash the official 4.1.1 image from google, will I still get OTA updates?

So I would have officially done nothing since I'm already running on 4.1.1 right?

Flashing a ROM, bootloader, recovery, or even a new radio won't network unlock your device. The files responsible for the locking of the network reside in a different partition (called EFS), that can't be modified by flashing something. It needs a different hacking of which I personally don't know anything

Yes but I need a rooted rom in order to access that partition. I have unlocked phones before. But, in lieu of what you're saying. Theoretically speaking, if I were to unlock the bootloader, flash a rooted rom, network unlock the phone, and the restore it to factory settings with google's image, the network unlock should still be in place shouldn't it? And I should get my OTA updates.

Samsung didn't support unlocking because the bootloader for most providers are not locked in the first place.
If you have a custom recovery the OTA will fail. There has been some debate as to if having an unlocked bootloader will work as well on past devices, but time will tell.

Okay, thanks
While you're here, is there an easy way to install stock firmware and restore the phone back to official status after custom rom flash? I'm new to HTC, only did this with samsung phones via Odin.

This is trickier with HTC. HTC uses something called RUUs. I don't rember what they stand for but they will do a full flash of stock firmware.
The catch is they are not available for everyone. They are carrier specific, and so far I haven't seen any for the M8 yet. Hopefully they will release it soon. Once we have this it is a simple .exe that is done on a windows computer and will take care of everything.
Alternately you can use a custom recovery to flash a stock nandroid, and then flash a stock recovery image.

Unlock it like to use it what any carrier or what gotta be more specific cuz its already kinda unlocked to flash whatever you want
The locked bootloader is an HTC thing.
^^^^^ thinks you mean carrier unlock to use on another network, or do you mean root access to install software and tweak your system?

Sorry if I come off as a bit if an idiot, never messed with Samsung stuff before. I want to install a custom ROM, and I've tried using ODIN to install CWM but it doesn't seem to be sticking, it just keeps booting into the stock recovery.

Did you root your phone yet?

Nope.
You aren't coming across as an idiot.
I recommend TWRP, installed thru odin. You don't by chance have a Canadian phone? It has an "m" at the end of the model.
As soon as Odin shows 'pass' disconnect the phone and pull the battery before the phone reboots. Then put in the battery and boot.

Cannot Seem To Install Custom Recovery. Rooted And I THINK Bootloader Is Unlocked

Cannot seem to install custom recovery. Rooted and I THINK bootloader is unlocked.
Hi everyone, I'm in dire need of help.
I believe my bootloader is unlocked and I'm rooted using the one click method. But no matter what I do I can't seem to get a custom recovery installed. Please help me and advise me on what to do.

After you unlock your bootloader the splashscreen when booting has a WHITE background, not black. Unless you have seen and replaced the splashscreen then you haven't unlocked the bootloader and you can flash until the cows come home but it won't do any good...

Ah you're right. My bootloader isn't flashed after all. And even that isn't possible for some reason, neither the unofficial or official way is working
Oh my God, I don't know how but the official bootloader unlock tool just worked! Victory!

Congrats, just be aware now though that you are without warranty and won't be on the OTA list from ASUS...

Even if your bootloader is unlocked, still u will receive OTA updates.
My Z008 is unlocked and rooted. still i receive OTA updates. I just unroot and update the OTA and then re-root.

Official unlock tool or XDA unlock tool?
Once you unlock using ASUS's tool it removes you from the update server or so it has been said...
You can still download from ASUS site and flash through recovery but it generally don't get OTA's...

Relocking bootloader question

Hi hope someone can verify.
I'm running stock 3.2.7 unrooted with stock recovery. The bootloader is still unlocked as I tried out a few custom ROMs about a month back. I now want to wipe and sell the phone so need to lock the bootloader. Can I just do the standard OEM lock in adb or should I also sideload the full 3.2.7 update zip again?
Thanks
just oem lock it. but everything will be removed when you do that.

Thanks, I thought so but I had to check. Strange... after rooting phones and installing custom ROMs for maybe 8 years, I don't think I've ever relocked a bootloader.
It's safer to flash stock again then to relock bootloader, even if you think you are stock (including recovery) maybe you are not.
But except the booting screen, you won't gain anything from relocking bootloader, even the warranty will work with bootloader unlocked.

Thanks, but I plan to sell my OP3 to a high street store that buys and sells second-hand phones and tablets. Although it's only 3 months old and in immaculate condition, I'm guessing they may be reluctant to buy it if the start up screen says 'this phone can't be trusted...'
No choice in this situation - I will need to relock the bootloader I guess.
If you lock the bootloader, everything will be wiped and phone won't boot till you flash OOS.

Thank you. So after OEM lock, when you say flash OOS do you mean sideload a full update zip? That's what I was asking in my original post.

Ta mate. I already saw that thread but as I'm running a clean sideloaded OOS that has never been rooted, I am already back to stock. Anyway, as opinion seems to be divided on whether OEM lock alone is enough, I will also sideload a full OOS update zip again to be sure.
Won't be doing it for a few days though so it's all academic at the moment.
