How to Update Galaxy Tab 3 7.0 SM-T211 to Android 4.1.2 UBANC1

If you’re in the mood for something new for your Galaxy Tab 3 7.0 SM-T211, Android 4.1.2 will perform a make-over. The procedure we want to talk to you about will bring everything you ever wanted to have on your tablet. To perform it, some steps are needed. But more on that below.

If your gadget is the Samsung SM-T211, you live in Mexico and your gadget’s carrier is Movistar, this guide is aimed at you. No other tablet will do well with UBANC1, the firmware we’ll use for today’s upgrade. So be sure to only use the device we recommended, otherwise you risk bricking a model with another name.

In case the update lands on a tablet with root access, your gadget will get stripped of the latter. Also, its system partition will be deleted. You will still gain access to important data and the tablet’s own internal / external SD cards will still be available for use.

The novelties of this new OS are all impressive. For starters, this OS will deliver touch anticipation, a free style widget and all share. Then there are these to anticipate: automatic adjustment for the size of widgets and Google Now. Other offerings: pop up play, triple buffering, extended Vsync timing and a new keyboard. Also new are the following features: sync and connect email updates and a fixed frame of 60 fps. For the final list of goodies we have mini apps and group cast.

The new firmware does not allow you to do an upgrade via KIES. But the procedure can still be performed if you opt for OTA (should you not want to use this tutorial). The over-the-air method needs your tablet to run stock ROM; our own method is fine without one.Galaxy-Tab-3-7.0-SM-T211
