[Q] Bootloader unlocked

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

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

+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.

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.

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?

Bootloader locked and phone still rooted -- how do I return to stock?

I ran techfanatic's one-click script to unroot and restore my phone (VZW Galaxy Nexus) to 4.2.2 . It simply locked the phone but didn't unroot or restore it to stock. When I power up into the bootloader it says I'm locked, but I still have root access and the custom ROM I installed. I need to revert to stock, unroot, and lock the bootloader so I can return the phone. Please help!
My guess is I can't flash the stock ROM and unroot the phone while the bootloader is locked. So what happens if I unlock the bootloader now? I'm not sure there is any stock ROM on my phone for it to go to after it resets everything in the process. Can I simply unlock it, let it do the reset, then flash stock, unroot, and lock it back up?
I have SDK and the stock 4.2.2 image on my Mac and would love to get it on there.
Thanks

So if I have it right this is what I need to do?
1. factory reset
2. unlock the bootloader
3. install stock
4. unroot
5. lock the bootloader

You don't need to factory reset first or unroot, since you're flashing stock images, it will flash userdata.img, which will remove all /sdcard/ contents, and system.img, which will overwrite /system, which is where root was. Zepius had already told you this.

Android 4.4.2 update

I'm new to this forum and was wondering if I update my nexus 7 (2013)to android 4.4.2 without a unlocked bootloader, custom recovery, and not rooted, would I be able to root, get a custom recovery, and unlock the bootloader after I update?

Sure
sure you can root, get CWM and install custom roms .

Yes, you can do it at anytime. Just remember that unlocking the bootloader will wipe your device including wiping whatever is in your storage. Just like doing a factory reset it wipes Everything! AFTER you get a custom recovery you can do a factory reset from inside of recovery without wiping your storage.

Toolkits? Yes, the only one I can think of off hand is wugs, or something like that, either here or in the Nexus 5 forum. I've never used toolkits, have you given any thought to learning adb? It's not that hard, the fact that I can use it proves my point!
