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.
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.
