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


If you prefer using our guide, then perform these guidelines first:

  • a tablet with a fully charged battery is indicated, so check your gadget’s charge levels;
  • go to this page and find USB drivers to download on your laptop;
  • your notebook’s OS needs to be Windows;
  • deactivate the security solutions employed by your notebook;
  • then disable the ones used by the Galaxy Tab 3 T211;
  • turn on USB Debugging on the tablet;
  • make several backups;
  • create a full NANDroid backup.

Step by step instructions

Start the update of your gadget with the download of a bunch of packages.

  1. The first of them: the Jelly Bean 4.1.2 UBANC1 official firmware for Mexico (Movistar), which can be downloaded on your notebook. Then there’s Odin v3.09, which you will find available here. Once they’re downloaded and saved, they have to be extracted. A good way of doing that is through one of these methods: WinZip or WinRar.
  2. At the end of the unzipping phase, you will notice the addition of some files. The one that interests you for the update is Odin v3.09.exe.
  3. Open it on the notebook, then boot the tablet in Download Mode. This mode needs to be entered into like this: press and hold Home, Power and Volume Down at the same time, look for a boot message on the screen, then press Volume Up.
  4. If your Galaxy Tab 3 SM-T211 is done with the previous step, you should establish a connection between your laptop and your tablet. The latter’s USB cable has to be used for the plugging. If everything goes without issues, a blue sign will be revealed by the Odin, so add the firmware file to the AP / PDA.
  5. As for the next step, you will have to tick both F. Reset Time and Auto Reboot. If you notice a checked Re-partition box, our recommendation is this: uncheck it. You need to focus on the flashing of the UBANC1 now. To begin this process, tap “Start” and have patience until it stops.
  6. Which will happen after your tablet displays “Pass” and then reboots. The fact that it does all of that means that the update is nearly done. After the device decides to restart, you will know that you can disconnect the laptop from the tablet and get acquainted with the Android 4.1.2 Jelly Bean.
  7. The new operating system helped by the UBANC1 is inside your gadget’s About Tablet. To get to it, tap Settings on the Galaxy Tab 3 7.0 SM-T211.

After you see it launched on the tablet, make sure to enjoy the OS by testing its capabilities. If you’re not at all satisfied with what you see, time to use the NANDroid backup file and restore the tablet’s previous ROM. The restoration will then revoke the upgrade procedure.
