It’s now possible to unlock and relock bootloader on Google Nexus 10

As you might know, two of Google’s most anticipated devices have been launched earlier this week on Google Play. I’m talking about Google Nexus 4 and the controversial tablet Google Nexus 10. These two little wonders have been sold out in less than a few hours after going on sale, even if they have a spicy price: Nexus 4 starts from €299 and Nexus 10 from €399.

Today we are going to focus our attention on Google’s Nexus 10, due to the fact that is one of my favorite Android tablets. This device was first announced on October 29 and since then Android lovers haven’t stopped talking about it. There were lots of rumors regarding Nexus’s specifications, but today we are able to provide you some official information.

It looks like the 10-inch tablet comes equipped with a dual-core ARM Cortex A15 processor, 2GB of RAM and advanced MIMO WiFi technology that makes the Android 4.1.2 Jelly Bean experience even more attractive. Even if it has an ultra-thin display this little thing supports a resolution of 2560-1600 (300ppi) which means that watching and creating full HD movies will be on a regular basis.
It’s amazing to see a device, that has only 8.9 mm thickness and 603g and still support 16/32 GB of memory. All these combined makes from Google Nexus 10 a “lethal weapon” for Android lovers.
Enough with this technical information and let’s step to serious “hacking” opportunities.

In the guide below I’m going to show you how to unlock/re-lock your Nexus 10’s bootloader, so that you could install your favorite custom ROMs and applications in the near future.

Requirements and warnings
  • The first thing you should do when you are about to act as an Android developer is to do a full backup of your personal data. Check out this guide on how to do it.

  • These procedures require a lot amount of power and that’s why your Nexus 10 should be charged properly – 50% at least.

  • Make sure you have a compatible USB cable for your tablet and that its USB drivers are successfully installed.

  • Make sure the “USB debugging” option is Enabled. Go to Settings> Developer options > USB debugging. If you don’t find the “Developer options” tab anymore, just follow the next guide on how to bring it back.
