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.

Hi, just flashed the Google Factory Reset Image for GN (Android 4.0.2).
Should i lock the bootloader again (seems to be recommended from Google's side)..?
Im not gonna run custom software at this time.

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.
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.
Allons-y
This was something I was thinking about while I was at work earlier today. While setting a screen lock and using an app protector app will protect my phone from unauthorized access while it is on, there is currently nothing that I am aware of that can keep a thief who is in the know about rooting and flashing ROMs from booting my phone into recovery resetting it, and modding it to his liking. My question is, is there a way to encrypt my recovery image (I use TWRP) to make it accessible only after a passcode is entered? Or is there a recovery out there somewhere that has this built in?

Even if you were to password protect your recovery, if you're worried about a tech-savvy thief they'd just have to toolkit flash (or adb if they had a brain) a factory build and poof.

Which brings up another issue I was pondering. Encrypting the bootloader, or possibly flashing one that can't run adb commands without a password.

Use bootunlocker for nexus devices (on play store) to lock your bootloader and unlock it when you want to flash something. If you do that plus flash the stock recovery and turn off USB debugging, your device will be secure. If someone can't unlock your phone and run bootunlocker, they will have to fastboot oem unlock in order to do anything, which will wipe your data from the phone. It adds more steps if you like to flash and modify things, but it leaves Android's security intact.

Stock recovery? So does this mean that the only way I can prevent a tech savvy thief from accessing recovery and flashing a new ROM is by not being rooted?

Pretty much. That's why a lot of companies require encryption and unrooted devices for Exchange purposes.

You can still be rooted (assuming you use the literal definition of superuser). With the bootunlocker app, you can unlock the boot loader, reboot bootloader, flash custom recovery, flash ROM/mod in recovery, reboot boot loader, flash stock recovery, and relock bootloader again with the app. Unless someone knows your password or pattern, they won't be able to do that. They can only erase the entire phone to gain access.

Ok, here's another question. How do I flash the stock recovery?

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.

Stock image flash from fastboot. All wiped clean.
R: How to wipe all data from Galaxy Nexus?
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?
Hi I'm just wondering, I'm on whatever rom the phone came with. Official OOS latest update. No root. No unlocked bootloader... For the first time ever with a phone I think?
I'm tempted by the community builds but just want to know for certain,
Do I need to unlock my bootloader? Someone said this and I thought that was strange considering you apparently side load it via adb in stock recovery.
Will I lose my data? If I will then I'll wait until after my 4 days at work as I need my phone as it is really. If not I'll flash straight away.
Thanks!!

You can sideload without unlocking bootloader.
But you'll want to unlock the bootloader to make any further modifications after sideloading CB.
Also the phone will be wiped and reset to factory settings on unlocking the bootloader.
Thanks for the reply. So if I side load without unlocking bootloader it will be just like an update and no data wipe will happen?

Actually I haven't tried it but theoretically no data loss or errors should happen as you are still switching to a Marshmallow based ROM and that too from Oneplus itself.
You're good to go.
If retaining stuff is important to u, u should root and unlock bootloader, it does not void warranty, use titanium backup and just go through trwp, so if anything does ever happen in the future u will have ur backups
I've always used root and stuff but lately I'm enjoying no root. Using Android Pay etc.
