Upgrading the Samsung Galaxy Ace Plus GT-S7500 to official Android 2.3.6 Gingerbread build DDLB1


Published onApril 15, 2012

The Galaxy Ace Plus GT-S7500 is an awesome mid-level smartphone complete with a 1 GHz processor and 3.65-inch touchscreen.  Out of the box, the device runs Android 2.3 Gingerbread but can later be upgraded to higher versions of Gingerbread.

The latest update for the Samsung Galaxy Ace comes in the form of build DDLB1 for Android 2.3.6 Gingerbread.  This update promises a new set of features and fixes for issues such as the one involving Wi-Fi, in which many users have a hard time connecting to their home networks.

For those of you who are having a hard time updating your device through OTA (over-the-air) updates, there’s another way: manually flashing the update through Odin3.  Continue reading the rest of this guide as we teach you how you can install the official Gingerbread update on your Galaxy Ace Plus GT-S7500.


  • Samsung Galaxy Ace Plus GT-S7500
  • A Windows PC
  • Fully charged phone or at least 70% battery left.
  • Enable USB Debugging on your phone. You can do this by heading to Settings > Applications > Development > USB Debugging. Make sure that there is a check mark beside that option.
  • Install the USB drivers for your phone on your computer.  (The easiest way is to install Samsung KIES.)
  • Temporarily disable any antivirus software, firewalls, and Samsung KIES on your PC as they may interrupt the installation process.
