Android 4.1 Jelly Bean Based AOKP for GSM Galaxy Nexus i9250

Advertisement

AOKP ROM – famous for its advanced customization options – is still making the transition to Jelly Bean, but the advantage of having a Nexus device is that you can try out ROMs much earlier than owners of other devices, and that too in a properly working form. A preview build of AOKP based on Jelly Bean has been released by the AOKP team for the international Galaxy Nexus, which works awfully well though it has only a few customization options of AOKP at this point.

NOTE: This is only a preview build of AOKP, so while everything works properly, don’t expect to find many customization options that you’re used to in AOKP ROM to be present here, as those haven’t been added to the AOKP Jelly Bean code yet.

Let’s take a look at how AOKP ROM based on Jelly Bean can be installed on the Galaxy Nexus.

Compatibility

This ROM and the guide below are compatible only and 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 and you should not attempt anything if you don’t know completely what it is. If any damage occurs to your device, we won’t be held liable.

  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: Don’t forget to at least make a backup of your APN settings, which you can restore later if your data connection does not work after installing the ROM. Use the backup guide to find out how.
  2. Unlock the bootloader on your Galaxy Nexus by following the guide → hereThis will erase all your data, including the data on the SD card, so back everything up first (see step 1).
  3. [Important!] Install TWRP recovery on your Nexus by following the guide → here. Make sure to flash the GSM version of recovery. You need recovery to be able to install the ROM and can also use ClockworkMod recovery instead of TWRP.
  4. Download AOKP ROM.
    Download AOKP  |  Filename: aokp_maguro_jb.zip
  5. Download the Google Apps package. This will install apps like Market/Play Store, Gmail, etc. which are not present in the ROM.
    Download Gapps  |  Filename: gapps-jb-20120717-signed.zip
  6. Copy the two files downloaded in step 4 and 5 to the SD card on the phone (without extracting the files).
  7. Turn off the phone and boot into TWRP/CWM recovery. To do this, press and hold the Volume Up + Volume Down + Power buttons together till the screen turns on. Then, scroll to the Restart Recovery option using the volume buttons, then select it using the Power button to restart in recovery.
  8. Now, tap on Backup, then slide the blue circle button at the bottom to the right to start backing up your current ROM, so that you can restore it later if something does not work out with the new ROM. After backup is complete, go back to the main menu by clicking the home button at the bottom left of the screen.
  9. Select Wipe, then select Factory Reset and then confirm the data wipe. This will not wipe your internal SD card’s contents, so do not worry. Then, go back to the main menu by clicking the home button after wipe is complete.
  10. Select Install, then scroll to the aokp_maguro_jb.zip file on the SD card and select it. Confirm installation by sliding the blue button.
  11. After installation of ROM is complete, repeat step 10, but this time select the gapps-jb-20120717-signed.zip file to install the Google apps package.
  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 will take up to 5-7 minutes.
  13. Returning to Previous ROM: To go back to your previous ROM, boot into recovery, select Restore, then restore your previous ROM by selecting it from the list.
