One of the prime advantages of having a Nexus device, other than the fact that official Google updates are released first for these devices, is the fact that awesome custom ROMs based on the latest OS version are also made available for these devices, thanks to an extremely active developer community.

Android 4.2 ? the latest flavor of Jelly Bean debuted with the LG Nexus 4 and the Nexus 10, and was also pushed out the the Nexus 7, and Galaxy Nexus on the same day ? November 13th. It is no surprise then, that the developer community has already swung into action and are experimenting with custom ROMs based on the Android 4.2 AOSP code for these devices.

We already know that an AOKP ROM is already out for the Nexus 4. Acclaimed developer Roman?is working on a yet unofficial AOKP build of Android 4.2 for the Galaxy nexus, and it has been ?uploaded to his Goo.im folder for whoever wants to download and try it out.

For those who are wondering what AOKP is, it is a custom ROM based on AOSP, and includes a ton of customization ?options which let you tweak almost every single corner of the UI, including the?lockscreen, notifications menu, and a lot more, while also letting you fine tune the performance of the device. It also includes inbuilt support for themes, and you can choose from a huge number of fan-submitted themes to change the look and feel of your device. This is an ?early build though, and has not found its way into the official AOKP build list as yet, so there are chances of a few odd bugs popping up. But it should work fine for the most part.

Without further ado, let?s move on to how we can install AOKP 4.2 on the Galaxy Nexus.

Compatibility

This ROM and the guide below are compatible only with the international GSM Galaxy Nexus, model number i9250. It?s not compatible with Verizon/Sprint variants or any other device. Check your device model in Settings ? About phone.

Warning!

The methods and procedures discussed here are considered risky, so try them out at your own risk, and make sure to read each step carefully before attempting anything. We will not be held responsible if anything goes wrong.

  1. This procedure will wipe all your apps, data and settings. Backup your Apps and important data ? bookmarks, contacts, SMS, APNs (internet settings), etc. This?Android backup guide?would help you.
    NOTE:?While most APN settings are automaticaclly detected by the OS, it would be a good idea to make a note of your APN settings, so that you can manually configure the APN later if the data connection does not work after installing the ROM.
  2. Installing a custom ROM requires an unlocked bootloader. Unlock the bootloader on your Galaxy Nexus by following the guide ??here.?This will erase all your data, including the data on the SD card, so back everything up first (see step 1).
  3. You would also need to install a custom recovery like TWRP, for flashing this ROM. You can use this?handy guide to install the latest version of TWRP?on your Galaxy Nexus.?The guide is meant for the Nexus 4, but will work perfectly for the Galaxy Nexus as well.
  4. Download the latest version of the AOKP 4.2 ROM from the Roman?s Goo.im folder.
    Filename : aokp_maguro_unofficial_Nov-27-12.zip?
  5. Next download the Android 4.2 Gapps package. ?AOSP based ROMs come devoid of the default Google apps such as Gmail, YouTube, Search, Talk etc and would have to be installed separately ?| Download 4.2 Gapps
  6. Copy both the AOKP 4.2 ROM and Google apps zip files to the SD card on the Galaxy Nexus (copy the files as they are, don?t extract them)
  7. Turn off the phone and boot into recovery. To do so, press and hold the?Volume Up + Volume Down + Power?buttons together till you see a green android on its back and the letters?Start?at the top right. Press the?volume up??key twice to highlight the Recovery Mode option, and use the Power key to select it and boot into TWRP.
  8. First thing to do in recovery, before flashing any ROM is to take a full Nandroid backup of your existing ROM. That way, you have a fallback option in case things get messy with the new ROM. To do this,?tap on?Backup, make sure the?System, Data and Boot?boxes are?checked, and slide the blue circle button at the bottom to the right to start backing up your current ROM. After backup is complete, go back to the main menu by clicking the home button at the bottom left of the screen.
  9. Next from the Main menu, Tap?Wipe, then select?Factory Reset?and confirm wipe on the next screen. Now Tap?Cache?from the Wipe menu and confirm wipe on the next screen. Once done, Tap?Dalvik Cache?and again confirm wipe on the next screen. Once done, press the back button to go back to the main menu.
  10. Now from the main menu, tap?Install, and on the next screen navigate to the?aokp_maguro_unofficial_Nov-27-12.zip?file you transferred to your phone in Step 6, and select it. Slide the blue circle on the next screen to start the installation of AOKP 4.2
  11. After the ROM installation is complete, repeat Step 10, but this time select the Gapps package instead, and confirm installation.
  12. After installation is complete, select the?Reboot system?button to reboot the phone and boot up into AOKP ROM based on Jelly Bean. First boot may take a while, which is normal, so please be patient.
    NOTE:?In case you want to go back to your previous ROM, boot into TWRP recovery, then select?Restore, and restore your previous ROM we backed up in Step 8 by selecting it from the list.
