The Android 4.1.1 Jelly Bean has been launched and now an XDA forum member and developer called ‘legolas93’ managed to create a working AOSP ROM of Android 4.1.1 Jelly Bean that you can install on your Nexus S smartphone.

AOSP means that this release of Jelly Bean 4.1.1 is based on Android’s open-source code and it incorporates all default Jelly Bean features and services. The developer said that everything works and you shouldn’t have any problems using this release. Before you can start flashing it, you should read the preparation guide and learn what steps you need to take in order to correctly configure your device so that you’ll manage to update your Nexus S to Android 4.1.1 Jelly BEAN AOSP ROM.
Make sure that before moving to the tutorial you read all the info I’ve listed in this article and in case you can’t understand some of the steps then you should ask for my help by leaving a comment in the designated comments section at the end of this post. Now that you know all of the above you should move to the preparation guide:
- apply this update only on the Samsung Nexus S device. It won’t work with any other smartphone.
- during the update tutorial you will be asked to wipe all data and this means that you should backup all important files on your device’s internal sdcard. Move the files there as this will be left unchanged.
- if you wish to backups applications, SMS, Call Logs and APN Settings then you should use these specific Android apps from Google Play Store: AppBAK for Android apps backups | SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore.
- Enable USB Debugging on your phone.
- Make sure that you charge the phone’s battery so that it won’t power down during the update.
- Sync the Phone Contacts with your Gmail account and you won’t the contacts phone numbers.
- your device should have the CWM Recovery installed as otherwise you won’t be able to flash the Android 4.1.1 Jelly Bean AOSP ROM.
- it is recommended for Android advanced users to apply this update.
- create a full backup of the currently installed ROM so that in case you don’t like how Jelly Bean works on your Nexus S, then you will be able to restore it back the original one. Use ROM manager or even CWM Recovery to create /restore a full Nandroid backup.
I think that this is all you had to know and now you should move to the tutorial. Remember that you need to apply all the steps I’ve listed below and to post in comments in case you cannot complete it.
Update Samsung Nexus S to Android 4.1.1 Jelly Bean AOSP ROM
- Download the following zip file from here. This JB-Release .zip contains the ROM and the Super User files. Now extract the contents within the ‘JB-Release2’ zip.
- Download the Gapps package for Jelly Bean from here. This file shouldn’t be extracted and you simply need to save it on your PC. It will help you flash the Google applications such as Gmail, Play Store, Google Now etc. Connect your Nexus S to your PC.
- Move the two files extracted at step 1 and the Gapps package on your device’s internal sdcard.
- Power off the device and after that boot it into CWM Recovery move.
- When you’re in ClockworkMod recovery main screen you need to select the ‘wipe data/ factory reset’ option. Confirm this and when all data has been removed you should continue with the Jelly Bean installation process.
- Now select ‘install zip from sdcard’ and then, from the next recovery screen, select ‘choose zip from sdcard’. Point to the ROM zip file and install it.
- Repeat step 6 and install the ‘Gapps’ zip file, as the ROM you already installed it.
- Repeat again 6 and this time install the “Super User” files. After all these three files have been flashed you should return to the main recovery menu.
- Select ‘reboot system now’ and your device will now boot into normal mode. Note that the first boot into Android 4.1.1 Jelly Bean AOSP will take a while before completion and this means that you simply need to wait. Enter the Google account details and now you’ll be ready to use the new Jelly Bean ROM.
