The Galaxy Ace 2 I8160

The Android 4.4 KitKat recently released is exclusive for the flagship devices on Android, and it is also limited for those devices that have the Android 4.4 update. In short, users of the Samsung Galaxy Ace 2 will not be receiving the Android 4.4 KitKat, and the release of the Android 4.2.2 Jelly Bean is now also nearing its end. For those who are interested in the said Jelly Bean update, the XXNBI Android 4.2.2 Jelly Bean is available for installation through Samsung Kies or the OTA Update. However, not all are receiving this notification, so manual installation is the only option remaining.

This article will guide you through the step by step process of installing Android 4.2.2 Jelly Bean XXNBI on your Samsung Galaxy Ace 2 I8160. Since the official firmware is unbranded, users from all regions (provided that their device is not locked to any carrier) can install it. It is of utmost importance that you read the procedure carefully, and to follow it concisely. For those who are already familiar with Odin, then this tutorial would just be a walk in the park for you. Rooting your device or having Custom Recovery is not a requirement since this is an official firmware.

Note the following reminders before you proceed with the installation process:

  • This tutorial can only be used for Samsung Galaxy Ace 2 I8160. If this is not your device’s model, do not proceed.
  • Ensure that your remaining battery percentage prior to the installation is at least 85 percent
  • Allow USB debugging mode on your Galaxy Ace 2
  • Have a back up of your messages, contacts, and call logs. This will prevent you from unnecessarily losing important data and information in case a mishap occurs during the process. Better safe than sorry.
  • Have a back up of the EFS data of your mobile phone to avoid unwanted loss of mobile connectivity.
  • The methods needed to flash custom recoveries, ROMs, and to root your device can result in bricking your device. Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers. Be responsible and keep these in mind before you decide to proceed on your own responsibility. In case a mishap occurs, we or the device manufacturers should never be held responsible.


Now that you are all set and ready for the procedure, carefully read the step by step guide to successfully install Android 4.4.2 Jelly Bean on your device. Note that your entire app data will be removed if you upgrade to this ROM from a Custom ROM. Also, do not use Factory Reset using Stock Recovery because it will wipe out all of your content, including your photos and videos.
