How to update Nexus 7 with Android 4.2.1 Jelly Bean AOKP Build 1 ROM

ASUS Google Nexus 7 recently received a good treatment from AOKP (Android Open Kang Project) team. A custom ROM based on Android 4.2.1 was released yesterday bringing along more cool features and performance boosters. While the CyanogenMod team is stuck with their nightly CM10.1 ROMs for the Nexus 7, the AOKP team promises to bring even more goodies in their future releases.

Among the aspects that have received a bump in this release is over user interface, lockscreen, status bar and navigation bar. There are also new things added to audio settings with LED control and custom vibrations were added.

The installation of this ROM revolves around the use of ClockworkMod Recovery (CWM) tool. Users will be required to download this tool together with the Android 4.2.1 Jelly Bean AOKP Build 1 package. The entire process, if done correctly, will be done in a few minutes and the device will work like a breeze as this release is stable.


  1. First and foremost, your Nexus 7 should be rooted before you decide to continue updating with this ROM.
  2. The ClockworkMod Recovery tool should also be installed in your device because you will be using it all the way to the end to successfully install AOKP custom firmware.
  3. All of your important data should backed up before you take the first step of this guide to make sure they are safe just in case things happen during the process.
  4. Enable USB debugging in your device and make sure all necessary drivers were installed to make your device detectable by your computer. You will be copying files from the computer so it is imperative there is a good connection between them.
  5. This build is intended for ASUS Google Nexus 7 only and not for other devices. It is advised you first check the model of your device by heading to Settings => About tablet.

Step-by-step Guide

Step 1: Download two necessary files: Android 4.2.1 AOKP Build 1 ROM and Google Apps and save them into your computer. You don’t have to extract these files because CWM Recovery needs them zipped to be flashed into the Nexus 7.

Step 2: While your device is still powered on, connect it to your computer using the original USB data cable and copy the files you just downloaded into the internal memory. Make sure you save them in the root directory, otherwise, CWM Recovery cannot detect them.

Step 3: Disconnect your device from your computer, switch it off and boot it into Recovery Mode. You can do so by pressing and holding VOLUME UP, VOLUME DOWN and POWER buttons together until you reach the Bootloader Menu. Just follow on-screen instructions to proceed to CWM Recovery mode.

Step 4: You need to perform a full data wipe before flashing the custom ROM: choose Data Wipe/Factory Reset => Yes and go back to CWM recovery main menu after.

Step 5: You are now ready to flash AOKP ROM, select options Install zip from SD card => Choose zip from SD card and browse through your device’s internal memory where you’ve saved Android 4.2.1 AOKP Build 1 ROM. Wait until you are being brought back to the main menu.

Step 6: Repeat step 5 but this time choose Google Apps package instead of the custom AOKP ROM.

Step 7: You need to reboot your system to make newly-installed ROM work. The first reboot after the flashing will be longer than the usual so be patient and wait until your device becomes active.

It is imperative you don’t disrupt the process during the flashing of both AOKP ROM and Google Apps.
