Update Galaxy S3 i9300 to Jelly Bean with AOKP build 2 based Rootbox ROM

Advertisement

A few days ago, build 2 of the Android 4.1 Jelly Bean based AOKP ROM came out for multiple devices, which added many customization options that AOKP was once famous for when it was based on Android 4.0. Now, based on AOKP build 2, XDA Recognized Contributor bajee11 has released RootBOX ROM, which along with including all the features of AOKP also adds a few more tweaks, fixes and features from other ROMs like CM10.

Keep in mind that this is not an official Samsung ROM. It’s a custom ROM that is under development and may have a few bugs and issues, and some things may not work properly and some stock Samsung ROM features will not be available.

Currently, the following issues are present in the ROM, quoted from the source page (where the most updated list of issues can be found):

Known Issues (as of 22 Sept ’12)

No option to swap Internal/External SD card

  1. This procedure will wipe all your apps, data and settings (but it will NOT touch your SD cards, so don’t worry about those). 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 note down your network’s APN settings, which are required to make mobile data work. Go into Settings » More » Mobile Networks, click on the APN that is in use, then note down the setting for each field. While APN settings should be automatically restored from network, you can enter them manually if needed to make mobile data work. You can also find your APN details → here.
  2. Make sure you have ClockworkMod recovery installed. If not, use this guide to install it.
  3. Download the latest version of the ROM from the source page.
  4. Download the Google Apps package. This will install apps like Play Store, Gmail, etc. which are not present in the ROM by default.
    Download Gapps  |  Filename: gapps-jb-20120726-signed.zip
  5. Copy the downloaded zip files from step 3 and step 4 to the internal SD card (do not extract them, copy the zip files directly).
  6. Now, boot into ClockworkMod recovery. To do that, turn off your phone. Then, hold down Volume Up, Home and then the Power buttons together until the screen turns on, then let them go. The phone will boot into ClockworkMod recovery in a few seconds.
    In recovery, use the volume buttons to scroll up/down and the home button to select an option.
  7. Perform a full backup of your existing ROM, so that you can always restore it from recovery if something does not work out with this ROM. To perform a backup, tap on Backup, then slide the blue circle button at the bottom to the right to start backing up your current ROM. Go back to main recovery menu after backup is complete.
  8. Select wipe data/factory reset, then select Yes on next screen to confirm. Wait a while till the data wipe is complete.
  9. Select install zip from sdcard, then select choose zip from sdcard. Scroll to the ROM file on the SD card and select it. Confirm installation by selecting Yes on the next screen. The ROM will start installing.
  10. After ROM installation completes, select choose zip from sdcard again, then select the gapps-jb-20120726-signed.zip file to install the Google apps package.
  11. After the Gapps package finishes installing, select go back then select reboot system now to reboot the phone into RootBOX ROM. First boot will take up to 5-7 minutes.

NOTE: If you want to go back to your previous ROM, boot into recovery (as given in step 6), select backup and restore then restore your previous ROM by selecting it from the list.
