Flash Android 4.2.2 XXUANA2 on Samsung Galaxy Ace 3 GT-S7270

With Android 4.2.2 on-board your Samsung Galaxy Ace 3 GT-S7270, you will know what it means to have full control over your smartphone. An update and how to do it are waiting for you below!

If you’re all about upgrading the Samsung S7270, XXUANA2 will do the trick. The new firmware was launched earlier this month for Russia. If you use it on your handset, the pros will outweigh the cons. That’s because you will be able to play with loads of customization options, new features and so on.

Here is a more detailed look at what you’ll get after the update: the possibility to long-press the WiFi Bluetooth icons in Quick Settings so that you can easily toggle the on/off state, a USB debug white-list and a new set of download notifications. After that, you will also experience a new Gallery app delivering superior speed while loading, low battery bug fixes, a new set of sounds for wireless charging and bug-free Bluetooth audio streaming.

The new firmware is compatible with the model we mentioned. Installing the firmware on another smartphone will only brick it in the end. Also, if your Galaxy Ace 3 is in a rooted state, the update will revoke root access. System partition will be deleted, but these two won’t be affected: the internal/external SD cards and the important data.

If you’re wondering about the KIES logo: the XXUANA2 doesn’t come with an activated one. This tells you that you can use OTA (over-the-air) instead of our guide if you fancy this method. The OTA, however, works only on a smartphone featuring a stock ROM.galaxy-ace-3-S7270


The upgrade tutorial we prepared for today will now ask you to follow these pre-requisites:

  • download the Jelly Bean 4.2.2 XXUANA2 for Russia on your notebook;
  • download Odin from here on the same device;
  • go here and download, on the notebook, USB drivers for the Galaxy Ace 3 GT-S7270;
  • enable, on your handset, the option called USB Debugging;
  • if the phone’s not fully charged, do it now;
  • create both a regular backup and a full NANDroid one;
  • apply the procedure only if your laptop’s running Windows;
  • disable both the phone’s and your laptop’s security software.

Step by step instructions

  1. If the requirements are done with, use WinZip or 7Zip to do the following: extract the Odin and the official firmware on your laptop.
  2. We now need this from you: boot the handset in Download Mode via some easy steps. Which are these: after you simultaneously press and hold Volume Down, Home and Power, wait for the icon of Android and a screen of warning to pop up, then press Volume Up.
  3. Now launch, on the notebook, the Odin as Admin and take the phone’s USB cord to establish a connection between the device and the laptop. Give the Odin some minutes’ time to find the Galaxy Ace 3 S7270.
  4. After it’s done locating the handset, “Added!!” and an ID:COM box will both come up (the box should be in yellow or blue). If the connection fails to be established, don’t panic: you can install, once more, the USB drivers on the laptop or use another USB port.
  5. Now continue with this step telling you to do as follows: tap BL, opt for a file with BL in the name, tap AP, choose a file with AP in the name, tap CP, choose a file with CP in its name, tap CSC, select a file which has CSC in the name, click on PIT and choose a file sporting an extension with .pit in it.
  6. The next thing that should happen: check the boxes which are called F. Reset Time, Auto Reboot and Re-partition. After tapping all three of them, you will need to tap “Start“. This will allow the flashing of the new ROM to commence at last.
  7. The installation will only take a couple of minutes. When done, the Galaxy Ace 3 GT-S7270 is going to reboot in a short while. A message saying “Pass” will make its way on the screen.
  8. [sc name=”banner-jos”]After you see it appear, unplug the smartphone from your notebook. Tap Settings on the device, tap About Phone after that and then look for the new firmware.

Give the XXUANA2 a try or several on your smartphone. If it’s not how you expected it to be, restore the phone’s old ROM with the NANDroid backup file. You’ll see that the update process will be revoked.
