How to Install Android 4.1.2 UBAMH1 on Galaxy Tab 3 7.0 SM-T211

The OS your Galaxy Tab 3 7.0 SM-T211 currently sports can be turned into the latest Android 4.1.2. How? Find out the answer below!

The Jelly Bean 4.1.2 will become your tablet’s main operating system via an update. This procedure, though, will need special firmware for that. Peru, Chile, Colombia, Uruguay, Brazil, Panama and Trinidad & Tobago owners of the Galaxy Tab 3 7.0 T211 will need to install UBAMH1 to get access to the latest Android version; the new firmware was released this month for the two countries.

For this upgrade, you will need your Galaxy Tab 3 7.0 SM-T211. Don’t install the new firmware on another tablet; it will be bricked. The UBAMH1 official firmware which was released for Peru doesn’t have an activated KIES logo, which is why you should update the tablet with this tutorial or OTA via the Software Update button under Settings menu.

The variant for the rest of the countries has its KIES logo turned on, so you can choose to use Samsung’s KIES for the procedure. For both the OTA and the KIES methods, your device must come pre-installed with a stock ROM.

The new firmware will be responsible for the following novelties: a fixed frame of 60 fps, group cast, Google Now, sync and connect email updates, all share, pop up play, extended Vsync timing, automatic adjustment for the size of widgets, a whole new keyboard to use in your daily chores, touch anticipation, mini apps, free style widget and triple buffering.

But there are certain things that will affect your tablet if it’s rooted: the system partition of your gadget will be erased and the root access will be gone. The important data, however, and the internal and external SD cards won’t have to go through that.Galaxy-Tab-3-7.0-SM-T211

  • the notebook you’re working with should have USB drivers compatible with the tablet downloaded on it;
  • the tablet and the notebook both feature security software which must be disabled for the duration of the tutorial;

  • the operating system featured on your laptop should be Windows;
  • the tablet must have USB Debugging turned on.
