Update Google Nexus 7 to Official AOKP JB Milestone 1 ROM

The official first installment of AOKP JB Milestone is here and it is based on Android 4.1.2 Jelly Bean. You can use the instructions that I have listed in this post and you’ll manage to flash the custom ROM successfully. Note that this is a guide that can be installed even by beginners, but only if the instructions are carefully applied.

AOKP JB Milestone 1 comes with tweaks and overall improvements for your smartphone. Also, it is a stable build and you should upgrade to it in case you’re already running a previous build of AOKP JB on your Nexus 7 tablet. Note that in case you’re already sporting an AOKP JB ROM on your tablet, then you don’t have to read the instructions listed below as these are designed to be used on devices that are currently running a different custom ROM.

Here’s what you need to know before moving to the tutorial guide:

  • Flash the files listed in this post only on the ASUS/ Google Nexus 7 and do not attempt to flash them on any other devices.
  • It is recommended for you to create a full backup of the existing ROM. This file can then be used to restore your device to a working state in case something goes wrong and you cannot use your device after flashing the new ROM.
  • Enable USB debugging option on your device.
  • Your tablet has to be on an unlocked bootloader, rooted and having the CWM Recovery installed on it. Without these you cannot install AOKP JB M1 ROM.
  • Charge your tablet’s battery so that it won’t power off during the update process.
  • Note that we cannot be held responsible in case it gets bricked in the process. Read the entire tutorial and apply all the actions I’ve listed in it.
  • If you cannot complete the update, leave a detailed comment at the end of this post and we will give you new solutions to your problems.

That’s all the extra info you had to read before moving to the tutorial. This update should be completed in under 5 minutes as you simply need to flash only a couple of files. Now that you know all this, get to the tutorial and flash the new custom ROM on your tablet device.

How to install official AOKP JB Milestone 1 ROM on Nexus 7:

  1. Download the custom ROM zip from HERE. Save it on your computer and don’t unzip its contents.
  2. Get the Gapps file for Jelly Bean from HERE. Don’t extract its files and place on your desktop screen.
  3. Connect your tablet to your PC via USB cable. Now move the files downloaded at the steps above on it internal SD card. Unplug the USB cable from both device and then power off the Nexus 7.
  4. Boot your tablet into CWM Recovery mode. It can be done by pressing at the same time ‘volume up’ + ‘volume down’ + ‘power’ buttons. When the screen flashes you can release the buttons.
  5. From the main menu of CWM recovery select ‘wipe data/ factory reset’ option. Confirm. NOTE: If you’re already running an AOKP JB build 1,2,3,4 or 5 for Nexus 7, then you can skip this step. All other tablets that are running a different ROM should apply this step but you should know that the installed apps, sms and other files stored on /system partition will be removed.
  6. Now you have to select ‘install zip from sdcard’ and then select ‘choose zip from sdcard’. Find the AOKP JB M1 ROM and install it.
  7. Select again the ‘choose zip from sdcard’ option and find the Gapps file for Jelly Bean zip.
  8. After the AOKP JB and Google Apps zips are installed you can return to the main recovery screen.
  9. Select ‘reboot system now’. Your tablet will now start its first boot process with the new custom ROM and you should wait at least 5 minutes for it to complete.
  10. When the AOKP JB welcome screen appears it means that the update was successful and you can begin testing the new ROM.

NOTE: In case your device doesn’t complete the first boot, you should hard reset it and after you have to repeat the entire tutorial. Make sure that the second time you’re applying step 5 and wipe the data from your phone. Eventually you should be able to flash all files successfully without problems.

I hope that this guide helped you complete the update. In case you’re having any other problems with installing it, please ask for more help in comments.

Also, if you don’t like this new ROM, then you should restore the ROM backup you’ve created before installing the AOKP JB M1 ROM.
