If you’re up for an update, get your Galaxy Ace 3 LTE GT-S7275B ready for this guide!

The Samsung S7275B is going to end up with as many novelties as possible when you’re done with our guide. Making this possible is the latest official firmware to come out for your device: Android 4.2.2 Jelly Bean UBUANE2. If you want to update another model with it, we recommend using a different tutorial. The new tool only works for the model we’ve included in this post.

After you know what device to use and what firmware the latter will contain, let’s find some more info on the new tool. It was launched this month for Argentina. Its KIES logo is turned on. What does that have to do with anything? Well, this gives you the chance to upgrade your handset with the KIES software. Use this only if stock ROM is already part of your device. If it’s not, this guide doesn’t need a stock ROM to be performed.Galaxy-Ace-3-LTE-GT-S7275B

The benefits of this official firmware

Once you have root access on your phone and you want to upgrade it, you’ll experience certain damage. The procedure will quickly affect the smartphone’s system partition. After the latter’s been erased, root access will end up being revoked. The update doesn’t delete important data; internal and external SD cards are also safe from damage.

An update delivers really great assets for your Galaxy Ace 3 GT-S7275B. Special mention is given to the following goodies: low battery bug fixes and new features. Your phone gets to use these, too: a USB debug white-list and a new set of download notifications. There’s also this: the option to long-press the WiFi Bluetooth icons in Quick Settings to be able to toggle the on/off state while using the device. Other novelties: better Bluetooth audio streaming and a new set of sounds for wireless charging. A new Gallery app concludes this list of goodies.


Ready to perform the update? There’s one more thing to do: requirements. Without further ado:

  • enable USB Debugging on your smartphone;
  • don’t forget to turn off the phone’s security programs;
  • the security software used by the laptop needs to be deactivated;
  • charge the battery of your Galaxy Ace 3 LTE GT-S7275B;
  • download USB drivers from this page on your laptop (they should be the ones which are compatible with your handset);
  • Windows has to be the only OS running on the notebook;
  • generate one or two backups to preserve the data inside your handset;
  • a full NANDroid backup should be created now.
