[Q] Bootloader unlocked - Samsung Galaxy Nexus

Hi, just flashed the Google Factory Reset Image for GN (Android 4.0.2).

No you should not. There is no reason to.

What he said. Just leave the bootloader unlocked and don't flash anything. You'll still receive ota.

The only danger of an unlocked boot loader comes from what you do with the phone from when it's unlocked .
If you feel confident with flashing etc then keep it open , if as you have stated you don't want to flash then you may as well just lock it . It's so simple to unlock in any case . Personal preference really

Yes, but every time you unlock it wipes all your data...

Yep it sure does . Best to clear all data if you flash anything anyway . Either way it's up to you , no advice here is wrong . Your decision )

+1... leaving it unlocked does no harm as long as you dont do any mods afterwards. Leaving it unlocked allows you to back up game saves / app data if you decide to root/modify again.
Just if you send it back for manufacturer purposes.. relock the phone.

I agree with you, that you should wipe everything when flashing a new ROM. However, I don't think I expressed my point properly: if your bootloader is locked, and say you want to flash a new radio, or a new recovery image (which do NOT require wiping your data at all), you CANNOT easily without wiping everything.

GNEX Unbrickable?

First, pardon my ignorance on this matter. Since Google released the factory imagines for the Galaxy Nexus does this allow you to restore the phone no matter how bad you brick it? Thanks in advanced

Well to do that you need to flash the bootloader.
If you screw up flashing the bootloader (like unplugging the cable when it's transfering the file), then you're dead.

Exactly.
On some of the SGS phones its possible to mod them to be unbrickable. Basically you can make it so it boots via USB (at least that's what I understand it to do)

Actually fastboot is a very safe protocol, it checks for sums before sending and before flashing so that the image is still intact. However if your bootloader is already corrupt on your computer or you dd (flash) some crap into the bootloader partition, your phone will be bricked.
I know a guy who wanted to return his HTC Desire HD. He replaced his bootloader with a porn image. I don't think I have to mention that the phone did not boot anymore
What is the method to fix a phone that is in a boot loop or something else.

No phone is idiot proof and as a previous Galaxy S II owner I have seen guys flash a i9000 (Galaxy S) ROM to their phone and then wonder why it does not boot and the amount of guys who flashed the partition table which also screwed their phones is unbelievable.
Bottom line is read the documentation and read it again and any questions ask on here and from there you cannot go wrong.

[Q] will unlocking bootloader wipe the SD?

Hi all,
My nexus is bought from one of the mobile operator in HK, sadly it is not a yakju-build
Though it seems not a big deal, I would like to flash a yakju-build.
If I has not misunderstood, I have to unlock the bootloader on my nexus before fastboot the img, which would wipe my nexus.
Now I am wondering if that would wipe the built-in sd as well?
Thanks
Yes everything will be wiped.

I can also confirm that my LTE version was wiped when I unlocked the bootloader.
Third confirmation, yes it will.

You guys sure? Wiping for a new rom doesn't, (unless you specifically do) the first thing I did when I got my GN was unlock and root, so I'm not sure.

I am not going to swear it's true but I am at least 90% sure...
Wiping for a new rom will not wipe the SD card but unlocking the boot loader will.

thanks for all the reply
time to unlock bootloader for some nice ROM...
almost forgot, will relocking bootloader wipe your phone?
(just in case i have to send my nexus for service...)
Re-locking it shouldn't but everytime you unlock, it will wipe it.
So if you lock then unlock for some reason it will wipe it.
Factory reset/wiping user data and cache to install a new ROM is different to unlocking the bootloader.

[Q] Is it possible to root without losing all my data?

I've read much about rooting, but it always seems to come in conjuncture with going into recovery mode and invoking factory settings..
Is there a way that I could just get root access without losing all of my data?
Thanks!

Akaik the answer is no. Once you unlock the bootloader the device gets wiped.
Looks like CF-Root might be able to do the job..

Alright! I love answering myself!
I just found out the CF-Root doesn't wipe the phone.
http://forum.xda-developers.com/showthread.php?t=1396952
Because: "THIS IS NOT A ROM - it is only a modified kernel. You need to have the relevant firmware already on your device. You do NOT need to wipe anything for this patch."
I'll try it an let you all know

Rooting doesn't wipe your phone, unlocking your bootloader does.

I doubt it: it's set up to do that because anyone can unlock it from fastboot and get full access to the phone, it's an attempt to prevent peeps getting access to the data on a stolen phone.

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.

How to wipe all data from Galaxy Nexus?

Hi, all. I will be selling my Galaxy Nexus in a few days and I want to wipe all data prior to selling it. I know about factory reset but I want to know if they are any additional steps or things I should do to make sure none of my data remains on it. It has never been rooted and is running the latest stock software. Thanks.

Factory reset its enough.

You can relock & unlock bootloader if you want to get everything wiped from your storage .
( that's considering you have unlocked your bootloader already . if you are not , you'll need to unlock bootloader & relock it again if you want to . but its no harm keeping it unlocked . )
The fact you need to know is that " unlocking the bootloader wipes your storage "
to do this boot into fastboot mode , get an adb window open
To unlock bootloader
type - fastboot oem unlock

New rom
So I flashed new radios, flashed new recovery, got a new rom & gapps and figured out the apps I want. Now I want to clean it all up. Can I unlock the bootloader and wipe everything if it is already unlocked? Will it harm anything to just go through the process again in order to completely wipe it?
