How to wipe all data from Galaxy Nexus? - Samsung 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.

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

to lock the bootloader

or you can use galaxy nexus toolkit .
so do a factory reset / unlock yourbootloader . everything is clean

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?

Removing root and locking bootloader?

Im returning my Gnex as I want it on Sim Free. 500mb data is just not enough.
How do I go about relocking the bootloader and unrooting the phone?
Im on OS X and I rooted and unlocked it with Pauls Superboot
For the moment, you don't.
Can't you just remove the Superuser apk's and then run "fastboot oem lock" (or relock not sure)!
I have never tried this and don't have a device so better wait for someone knowledgeable to post!
Check the Nexus S forums, should be in Dev section on how to re-lock bootloader. It's either relock or lock or re-lock. As for Superuser, download Titanium backup and use it to remove it.
fastboot lock/relock should not work unless it's an engineering device/some exploit is used.
Not sure about removing root, but I can confirm that the following command works fine:
fastboot oem lock

I would think a factory reset should return you to stock, if not, I'm sure someone will have the original boot.img and you can flash that via fastboot. Then factory reset again afterwards to be on the safe side. Finally fastboot oem lock and you're ready to go buddy!
Does fastboot oem lock remove the unlocked padlock image on boot?
Yes

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
Merry Christmas

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.

[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.

Rooting help

I have unlocked my bootloader previously and it did wipe everything, but if i want to get root does it wipe my phone once again? I unlocked bootloader with toolbox, but it doesn't give a tip for that if it wipes my phone again... fustrating

Unlocking the bootloader wipes everything but rooting does not.

There are enough guides on how to do this. Please use google..
!This WILL wipe the internal data!
1. Download the 4.3 Factory image and extract it to your fastboot folder.
2. Reboot into bootloader after you backed up important things to the computer.
3. Type 'fastboot oem unlock' and highlight yes with the volume Keys and select it with the power button.
4. Type 'flash-all.bat'.
5. It'll reboot automatically.

Oh locked in that way. I am afraid I have to disappoint you. I read somewhere a guide on how to do it. But I cant remember where. Also I read somewhere that it is impossible. I cant help you here sorry. Google is your friend.
