[How-to]Unlock/Re-lock Nexus 10 Bootloader

udimars30 · Nov 12, 2012

First Of all Thanks to AndroidCentral for this!!!

I am not responsible for any bricked device
Try at your own risk!!
Now Lets go and unlock the nexus 10!! :laugh:

Requirements"
Fastboot
Android SDK

Downloads:
fastboot (windows): http://cdn.androidcentral.com/sites/androidcentral.com/files/uploads/tools/fastboot-windows.zip
fastboot (mac): http://cdn.androidcentral.com/sites/androidcentral.com/files/uploads/tools/fastboot-mac.zip

Now lets unlock!!!! :highfive:
1.Power off your Nexus 10, and reboot it into fastboot mode by holding the volume up button, volume down button and power button.
2.Plug your tablet into a full speed primary USB port on your computer. If you're using Windows, you'll see the pop-up about drivers being installed and initialized.
3.Open the terminal or command prompt on your computer, and navigate to the folder you have placed the fastboot program in. if you have already done this before you might not get any prob in doing all this stuff!!
4.At the command line, type in (without any quotes) "fastboot devices". You should get a device ID returned, which lets you know that fastboot can see your Nexus 10
5.it is really important to get the ID of the device or else you cannot go further
6.After you have got the ID just type(without qoutes) "fastboot oem unlock" in your command window.
7.Look to your tablet, where you'll have to verify the process. Remember that there's no way to undo the data loss that will happen the instant you say "Yes".
8.When the tablet reboots, you're done. You're free to install custom software, modified boot images, custom recovery.

Enjoy your unlocked nexus 10 !!!

IF you want to RE-lock your bootloader
1.All the steps are same
2.on the 6th step just change the code from "fastboot oem unlock" to "fastboot oem lock" and also flash back to STOCK images (if changed) or else it wont boot
3.This will relock your bootloader so that only authentic, signed images from Google can be flashed to the phone.

Enjoy!!!

Any idea if this sends anything to the google servers? I know when unlocking the T700 it sends the serial to ASUS to void the warranty. Not sure if this was the case with any nexus device or not (also I realize this isnt out yet). Just figured i'd ask if you had any past experience with the N7 or prior nexus device

No, it doesn't send anything to Google, that's why they give you the option to relock the bootloader

of course man

fastboot is fastboot

You will probably need to run fastboot as root, though.

It isn't needed, if the sdk folder is in the PATH it will work normally

Re-lock

You should also mention in the OP that in order to re-lock you should flash back to STOCK images (if you have changed anything) otherwise the device will no longer boot.

Thank you, its been so long since I rooted my last device I've forgotten most of it - do I need a new SDK and if so where do I get it?

I'm running Mac OS X 10.7.5

Apoloiges for asking but it has completely left me.

no you don't need a newer SDK, if you have the platform-tools and tools folder you are good to go...

Sdk has been updated

Apologies but is there an online guide? Iv'e got no idea what I did before when I was on my Nexus One, I reckon I might as well delete the SDK and reinstall both SDK and Eclipse sO I can root with a clean system.

It would appear it is a lot simpler now as you can download a sdk / eclipse bundle from here

Why do you say that? I have my Galaxy Nexus locked again with a custom ROM and kernel and it works fine. Ive never seen mention of this non-booting thing if the bootloader is locked when running something custom

Egooktamuck · Nov 14, 2012

I unlocked the bootloader but now the tab will not start? I starts to the X of JB and then nothing happens... Help

I have the Solution :good:

If you have the same problem - Go into Stock-Recovery and make a "Factory Reset" then reboot the system.

It's may be wrong, I'm basing it on my XOOM days where it wouldn't boot it you relocked with anything other than stock. If that's different now, feel free to ignore me

I know that when an update comes out I have to relock the bootloader, but if I unlock it after the update does it wipe the device again
