WARNING

I am not responsible for any bricked device
Try at your own risk!!

 

Now Lets go and unlock the nexus 10!!   :)



 
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. 

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!!!  :)

TIP

If you get stuck in a bootloop rebooting the tablet after unlocking the bootloader...
Here's what you do..

 

1. During the bootloop.. hold the power button + volume up + volume down button simultaneously to get yourself back into fastboot mode as you were previously.
2. In fastboot mode.. use the volume keys to scroll to Recovery and the power button to select it.
3. In Recovery (Android robot on his back with a red triangle)... tap the volume up button and the power button simultaneously which will bring you into stock recovery. Again.. Don't hold the buttons, just tap them simultaneously. Also make sure you're holding the correct volume button. Up will be the volume key on the right.
4. Once you're in Recovery.. perform a factory reset/data wipe and then reboot your tablet... you should now be back to the Welcome Screen.

 

Enjoy :)
