Install AOKP JB Milestone 1 on Galaxy Nexus GSM I9250

The first installment of AOKP’s JB Milestone series custom ROM has been released and now you can use the instructions that I have listed in this article to learn how to successfully update your device. This is the most stable AOKP Jelly Bean ROM to date and it is based on Android 4.1.2, which means that it also packs some new functions besides the fixed bugs.

There isn’t any major update but only a pack that will make your Galaxy Nexus much more stable than before. Note that in case you want to flash this update over a previous AOKP JB Nightly build then you can do it without applying the factory reset step. In case your device is currently running a different custom ROM, then you should read the preparation guide below and learn which steps you have to take so that you’ll make sure that the AOKP JB M1 official ROM installs correctly and that you won’t lose any important data files during the update.

Here’s what you need to know before moving to the ‘how-to’ guide:

  • Flash the files that I’ve posted in this article only on the Samsung Galaxy Nexus model number I9250, which is the International GSM variant. Do not try to update any other Galaxy Nexus model with them because that might brick it and you won’t be able to restore the previous software.
  • Your Galaxy Nexus should be rooted and running a CWM Recovery image.
  • Use ROM Manager or ROM Toolbox Lite app to create a full ROM backup of the currently installed Android OS. This file can be used in case something goes wrong and you cannot use your phone after the installation of AOKP JB M1.
  • If you wish to backup apps, SMS, Call Logs and APN Settings, use these apps for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore | AppBack for Android.
  • To backup your Contacts, use your Gmail account and sync them with it. Here’s a guide that can help you do that.
  • Enable USB Debugging option from Android development menu.
  • Charge the phone’s battery so that it won’t discharge while you’re flashing this custom ROM update.
  • We will not be held responsible in case your device gets bricked in the process. Note that you’re installing this update at your own risk and you should be an advanced Android use if you wish to correctly install all files.
  • Read the entire post and only when you’re sure that you can complete it, move to the tutorial instructions.

These were all the general guidelines you had to read, now move to the next part of this article and learn how to install the Android Open Kang Project custom ROM.

How to update Galaxy Nexus I9250 with Official AOKP JB Milestone 1 custom ROM:

  1. Download the ROM zip from HERE and save it on your PC. Don’t unzip its contents.
  2. Download the Gapps for Jelly Bean zip from HERE. Do not unzip.
  3. Connect your Galaxy Nexus to your computer and then move both files on its internal SDcard. After the transfer is finished, disconnect the devices and then power off your smartphone.
  4. Boot into CWM Recovery mode.
  5. Select ‘wipe data/ factory reset’ option from CWM Recovery main screen and confirm this process. Note that in case your device is already running an AOKP JB build ROM, you can skip this step and move to the next one, as the wiping process is not required.
  6. Now select ‘install zip from sdcard’ option. From the new screen select ‘choose zip from sdcard’ and then find the ‘AOKP JB M1 ROM’ file and install it.
  7. Repeat the same actions for the Gapps for Jelly Bean file. When these files are installed, return to the first menu of CWM Recovery.
  8. Select ‘reboot system now’ and wait until all boot files are loaded successfully. Enter your Google Account credentials when the home screen appears and you’re done, the install was completed.

NOTE: if the first boot process of AOKP JB milestone 1 ROM takes too long to load or the phone gets into a boot loop, then you should power off the smartphone. Remove its battery and then re-insert it back in its place. Repeat the entire tutorial starting with step 4, only that this time you should apply step 5 no matter what.

I think that these are all the instructions I had for you. If you have any extra questions please post them in comments.

If you don’t like this new ROM, use the ROM backup file created before installing AOKP JB M1 and restore it using CWM Recovery, ROM manager, ROM toolbox lite or whatever app you’ve used to make it in the first place.
