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!!

Requirements"
Fastboot
Android SDK

Downloads:
fastboot (windows): http://cdn.androidcentral.com/sites/...ot-windows.zip
fastboot (mac): http://cdn.androidcentral.com/sites/...stboot-mac.zip

Now lets unlock!!!!
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 .

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

Arrow 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.
