How to install Android 4.2.1 Tablet UI AOSP Custom ROM on Google Nexus 10

Posted on Jan 15 2013 - 8:50am by Harold Hisona

Google Nexus 10, which is built by Samsung, was the first tablet to Android 4.2 Jelly Bean operating system. While majority of the existing owners of the tablet probably want to stick with the stock firmware the device comes packed with, there is a way to make things a little better and faster. That includes flashing of the latest Android 4.2.1 Tablet UI via the Android Open Source Project (AOSP) custom ROM.

There are certain risks included when flashing unofficial firmware into the device but it’s all worth it. If you are one of the people who want to take that risk to make your device better, continue reading below as we will walk you through successful installation of this ROM.

Requirements

  1. It is advised you fully-charge your tablet or check if it has, at least, 80% battery left. This is to avoid interruption during the process; there were reported cases of owners having their tablets bricked because their device ran out of power during the update process.
  2. USB Debugging should be enabled and all necessary drivers should be installed to make sure the tablet can be detected by the computer. It is imperative because you will need to connect your device to your computer and copy files into your device.
  3. Your device should be rooted as flashing custom ROMs need root access and that ClockworkMod Recovery should be installed because it is to be used for installation.
  4. Backup all your data including your videos, files, SMS messages, APN settings, etc. This is to make sure you can retain your important data just in case things go  bad during the process.

Step-by-step Instructions

Step 1: You will need to download Android 4.2.1 Tablet UI package and Google Apps. Save these packages to your computer and make sure you put them in a directory you can easily find and access.

Step 2: Connect your tablet to your computer using the original USB data cable and copy the packages into the root directory of your Nexus 10′s internal memory. You can only do this if you have already installed all necessary drivers. Otherwise, your device will not be detected by the computer.

Step 3: Turn your device off and disconnect it from your computer.

Step 4: You may now boot your tablet into Bootloader Mode: you can do so by pressing and holding VOLUME UP, VOLUME DOWN and POWER buttons together.  Choose Bootloader => Recovery.

Step 5: Once inside the ClockworkMod Recovery console, perform a full data wipe: Data Wipe/Factory Reset => Yes.

Step 6: You are now ready to flash Android 4.2.1 Tablet UI into your Nexus 10: choose Install zip from SD card => Choose zip from SD card and browse through your device’s internal memory and find the custom ROM. You need to confirm your action so the flashing will begin.

Step 7: Repeat step 6 but this time around choose the Google Apps package instead of the custom ROM. The flashing of both packages may take a few minutes to complete so you have to wait.

Step 8: Go back to main menu and choose Reboot System Now.

Your tablet will get rebooted and it will be longer than usual. However, the next time you restart your device, it would be faster like before.

To verify if the installation was successful, head to Settings => About tablet and look for the Android version.
