Root Galaxy Tab 3 7.0 SM-T210/T210R running on Jelly Bean 4.1.2 Firmware

Galaxy Tab 3 7.0 SM-T210 and SM-T210R that sport Google’s Android 4.1.2 Jelly Bean official firmware will find a new way to impress you. By rooting one of these tablets, you will see what we mean.

But if you want to find out more about what exactly this procedure is about, read the following: your gadget is going to largely benefit from different root-only apps as well as a custom ROM or many more, customization options, better performance, a battery performance that will outshine the current performance and so on.

Because a rooting process is very important and sought-after by gadget owners, there is a wide variety of methods that can be used to first achieve an update to the Android 4.1.2 Jelly Bean official firmware.

Because the model we are using for our guide uses the Samsung Galaxy Tab 3 7.0 SM-T210 and its sibling, the SM-T210R that was upgraded to that particular operating system. Check up on your variant by opening your device, then find “Settings” and tap it, select “About Tablet” from there and tap “Model Number” afterwards.


When you see that you are using the right model, you must abide by the requirements we are detailing below:


  1. The file we will mention now is very much needed on your laptop: (file name: prerooted.tar.md5). If you’ve downloaded it on the device we mentioned, you should unzip it. Then search for Odin tool, download it on the PC and extract it there, too.
  2. This will result in some files; the most important ones are these: .tar.md5 and Odin3 v3.07.exe.
  3. The tablet needs to be switched off and then booted into Download Mode; the latter action requires you to simultaneously press + hold Home, Volume Down and Power. If a message of warning pops up on the display, this means the following: press Volume Up and the Download Mode will finally be reached.
  4. Look for the Odin Mode; it is on the top of the screen. You should also look for this message: “Downloading… , Do not turn off target!!“.
  5. Double-click the Odin tool 3.07.exe file to open the Odin file, you have to plug the tablet to the notebook and see if there’s any “Added!!” message somewhere on the screen. The two devices are now plugged to one another; but if they are not, then be sure to re-install the USB drivers or try again with another USB port. Once the tablet has been found by the Odin, you should do this: tap “PDA“.
  6. [sc name=”banner-jos”]Now opt for either the *.tar.md5 or the *.tar file. Go to “Options” afterwards and uncheck Re-partition. Then check “Auto Reboot” and tap “START”.
  7. The file we just talked about here will be flashed on one of your gadget. The end of the process will be marked by this message: “Pass” enveloped in a green-colored background.
  8. Next up, the tablet is going to reboot. After the update has ended, you need to launch “Settings” on the gadget, then “About Tablet” and “Android & Baseband version“.

In case the process doesn’t go well, do this: re-install the file again by repeating this guide until your tablet is rooted on Jelly Bean 4.1.2 Firmware.

    what the fuck, now my screen is completely black and my machine isnt responding at all!?? HELP!?

    • Catalin Nichita

      Which Android version do you have? Which is the step where you receive this error?

      • User

        This happened after I flashed the prerooted file and rebooted my device, I’m using 4.1.2 I believe, the stock Android version.

        The easiest and safest method to root your tab 3 is just to flash TWRP recovery, reboot into recovery and then backup phone then hit restart system, it will then prompt you to root and select yes and just let it install super su and you’re good to go!

        No need to download 1GB files, no flickering or black screen and the operation is very simple.

    Hello, I recently attempted to root my Galaxy Tab 3 7.0. I seemed fine, but when I got back to the main screen, The color was messed up and it was flickering. I tried other recoveries and restored back to factory settings but it still has the issue. Can you help me fix it? Thanks

    Version: 4.1.2
    Model: SM-T210

      Which was the rooting tutorial used for your device?

  • N_mag

    Amazing, this was the only guide+rom I could get to run since there was no rom at all on my device :(, i had installed TWP custom recovery and then wiped the drive accidentally, removing the OS. The fix would have been easy of Odoin could use .zip but it cannot for whatever reason. The prerooted rom works like a charm thank you!
