I think this is the important step! How you get the menu!

"For those stuck at the boot loop. Reboot into boot loader and then go to recovery mode. Once you see the android with the red triangle press power and vol up at the same time. This will bring up the menu. Factory reset and you should get through the boot loop."

This is a lifesaver. Very helpful indeed.

    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 !!! :D

    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!!! :D

    How much time take the reboot of the nexus 10? I'm waiting about an hour and I'm a little afraid of...

    Try this, reboot back into the bootloader, then using the volume buttons select the Recovery option and select with Power. That will take you to a screen with a red triangle.

    In there, hold Power and press Volume Up, you're now in the stock recovery. Then select Wipe Data/Factory and select it. Reboot and it should be ok now.

    Good luck.

    I can go to the fastboot menu, and when I choose Recovery and press power it takes me to a screen with an android with a red triangle. There I press power and volume up simultaneously and keep it pressed, the screen turns off and the nexus 10 vibrates

    Here is the error. You have to hold down the power button continuously and then you hit volume plus. Then you get to the "Stock-Recovery"

    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 :cool:.

    Hey,
    I'm from the Nook Color Community. There is a SD slot for Nook Color and none for this. The unlock process seems to much more complicated. Do we lose all the /data when we unlock the Bootloader?

    Also, can we backup before unlocking?

    yes, it will wipe data, use adb to back up
