If you need to unroot your Galaxy Tab 3 7.0  either SM-T210 international or the SM-T210R United States and Canada variants, all you need is to revert back or restore back its original factory stock firmware.

How  to Unroot Galaxy Tab 3 7.0 SM-T210 or SM-T210R

First you should check your Galaxy Tab 3 7.0 specific model number, the international variants are SM-T210 while those sold in the U.S and Canada are SM-T210R.  To check the model number,  just simply hit your Galaxy Tab 3 7.0 Settings>>About Device>> then look for the Model Number alongside with all of the software version info.

Step 1: Do things as follows before Unrooting your Galaxy Tab 3 7.0

  • Make sure that your Galaxy Tab 3 7.0 s battery is fully charge.
  • Stock ROM packages comes in two formats the ‘Full-Wipe’ (delete your stored data after flashing) and the ‘Non-Wipe’ (it doesn’t delete your phone’s stored data) but it is highly recommended to make a back up all important files stored from your phone’s internal memory – contacts, messages, etc.  before flashing no-matter if it is Full-WIpe or Non-Wipe,  just to be safe and ensure that your stored data are in  safe  if something went wrong during the flashing process.
  • Remember or back up the APN settings of your device. ( This only done if you try to install other regions stock ROM.
  • Use a PC or laptop that runs in Windows OS, with a good and perfectly working USB serial port.  Odin will not work on MAC OS.
  • Use the supplied USB cable for your Galaxy Tab 3 7.0.
  • Enable USB debugging from your phone’s settings. Go to Settings > Applications > Development, and tick the box that says ‘Enable USB Debugging’. (on Android 4.2.2 you can go on Settings>>About Device>> Tap the Firmware Build version around 7-times. Then it will show you the USB debugging mode.
  • Closed Kies and not running in the system tray! Kies will interrupt and doesn’t like Odin, it will block you from flashing.

Step 2: Download the needed tools for flashing

USB Driver – download (only needed if you have not yet installed Kies in your computer)
Odin flasher tool – download

Step 3: Download your Galaxy Tab 3 7.0 Original Firmware or Stock ROM

Choose the right stock firmware that correspond to your Galaxy Tab 3 7.0 model number. A firmware for SM-T210 may or may not worked on SM-T210R variants and vice-versa.  It may contains a different kernel, bootloader and modem versions that result to soft-bricks.

SM-T210 (International)
UK -
BTU_T210XXAMKF  4.1.2 here
BTU_T210XXAMG2 4.1.2 here
SM T210R (U.S. and Canada)
USA -
XAR_T210RUEAMK1 4.1.2  here
XAR_T210RUEAMG4 4.1.2  here
CANADA -
XAC_T210RUEAMK1  4.1.2 here
XAC_T210RUEAMG4 4.1.2  here

Or grab any new firmware updates from here.

Step 4: Install the USB Driver and Extract the downloaded stock ROM

Install the USB Driver first to get rid of flashing failures. Also  need to extract the downloaded file which is packed in zip or rar files, so that you’ll get the tar.md5 file.

Step 5: Run and Configure Odin

Run Odin downloader Odin3_v3.07 on your PC desktop. Watch out the check-boxes options on the right top of Odin, ensure that the ‘RE-PARTITION’ is unchecked, only  the ‘AUTO-REBOOT and ‘F.RESET TIME’ checkboxes are both remained checked.

Step 6: Reboot your Galaxy Tab 3 7.0 into Download Mode

To reboot the Galaxy Tab 3 7.0 into  download mode , you need to turn the power off.  After it’s completely shut down,  just  press and hold the Volume Down  and the Power ON/OFF button simultaneously.

You should then prompted into a warning screen and asking you  to press volume up if you want to continue or volume down to cancel, just simply press volume up to get into download mode. The download mode then displays an Android robot and say’s “Downloading.. Do not turn off target!!”

Step 7: Connect your Phone to PC or Laptop

Once you already reboot the phone in download mode,  simply connect the phone to your PC or laptop USB.
In Odin window – the ID:COM box will turn to blue color and indicates the COM port number and a word “Added” on a log box will prompt you that the device is already detected or recognized by Odin. Your COM port number might be different from mine. If you do not see a COM port number then there’s something missing or wrong. You may read again from the top of this post.

Step 8: Load the binary .tar.md5 file

T he stock firmware comes in a single file only.  Now, you need to just simply click on the PDA button, then browse to the folder where the .tar or .tar.md5 you have previously extracted and then select and load it. An example below shows the Android 4.1.2 Jelly Bean stock firmware for US Galaxy Tab 3 7.0 SM-T210R.
example: T210RUEAMG4_T210RXARAMG4_T210RUEAMG4_HOME.tar.md5

T210RXARRAMG4 firmware

Step 9: Start Flashing or Installing the stock ROM

Once if all set and ready to fire-up, hit the “START” button in Odin to begin flashing the stock firmware.
Do not ever interrupt the phone while already in flashing progress, like disconnecting the cable or turning off the device. Just wait until it completely finish.

Step 10: Watch out for the word PASS!!

When the stock firmware installation successfully completes, you will then see a word “PASS” in Odin. This indicates that the flashing was already finish, and on the log box it says “All threads completed. (succeed 1 / failed 0)”. The phone will just then automatically reboot, then it’s time to remove it from PC or laptop USB connection.

Confirm if you successfully unroot your Galaxy Tab 3 7.0 SM-T210/SM-T210R.

Confirm your fresh firmware installed by going on to Settings>About Device>Firmware info.

Possible errors that you may encountered, this is based on my own experience while flashing stock ROM on Samsung Android devices. These are just a few hints on how to resolved it.

Q: I got an error message that says “Set-up connection Failed” ?
A: 1. Check your USB connection from the phone to PC,
2. Connect to another PC USB port
3. Check and try to another USB cable
4. Re-install the USB driver.
Q: Odin just suddenly stuck in the middle of nowhere while in flashing progress, It isn’t responding at all?
A: Check for possible program that might interrupt the process, like disabling the anti-virus and closing any running programs.
Try to use another PC or laptop,
Q: I experienced bootloop or the phone just stuck on Welcome Logo (phone always stop at bootanimation) and it won’t boot normally?
A: You can fix it via recovery mode option, do this:
Boot in recovery mode
1. Press and hold Volume Up and Power button.
2. Use volume keys to select, Up and Down and Power or Home key to select the option
3. Select Wipe Data/Factory Reset using the Home button.
4. Next select the Wipe Cache Partition
5. Lastly, select Reboot System Now to reboot your Galaxy Tab 7.0 in Normal mode.

    Hello, i have a little bit of an issue with the link to download the USA Stock Rom (XAR_T210RUEAMG4). Hotfile has been shut down and i would like to know if they can be re-uploaded

  2. daniel says:

    Great directions. I may have missed something but I did all of the above and restarted the phone but “wi-fi” is grayed out. Like it won’t let me try to connect to a wireless network. I should also note that at the top right corner there is a little No Sign (circle with a line diagonal on it). Is there something I didn’t do correctly?

    hi i have the tab 3 7 inch uk version build number is T210XXAMGE can you point me in the right way to download stock rom please and unroot thanks

    • Kim Bubble says:

      UK’s Galaxy Tab 3 did not have the MGE firmware. If it’s an unlocked version, then it must be running with other countries firmware like Germany, Italy, France since it’s all the same build. The MKF is the latest other than MGE, you can also flashed the MG2 then update your device on Kies to get the MGE firmware if available.

  4. Dom says:

    I had already rooted my Galaxy Tab 3 , firmware is T210XXAMG2 and now want to unroot. I did the procedure but everytime Odin gets after radio.img, I get Complete (Write) operation failed. I do see that the firmware is written UK and I am in Canada. What am i doing wrong?

    • Kim Bubble says:

      What root method did you use? It might have some tweaks that you cannot re-rewrite back the official firmware.
