Why we need to unroot if we already spent some effort to just have root?
Rooting is very fun though, as it will give us a full access to our tab but sometimes there are also downside from rooting. One of the common issues I’ve gathered around that if someone have messed-up from modding and ended-up into unwanted soft-bricks like bootloop and or just stuck in a welcome screen logo this very particular method is the best way we can rely to. This also useful if you cannot get any latest software updates anymore as long as your tab running on a rooted and a modified firmware there is a high risks that you will not get official software update supports and you’ll only receive an error message that says something like “Your device has been modified, Software updates are not available.” And no matter how many times you have tried performing Factory Data Reset and wiping the Data Cache Partition in tablet’s recovery mode but still you cannot get the update. Well, to ease that frustration this can also resolve such that OTA update failure issues as long you knew that you have been tinkering .

Step 1: Do things as follows before Unrooting your Galaxy Tab 4
- Make sure that your Galaxy Tab 4 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 4 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.
Step 3: Download your Galaxy Tab 4 Original Firmware or Stock ROM
For US and Canada Galaxy Tab 4 SM-T230NU Wi-Fi , SM-T237P LTE, international Galaxy Tab 4 Wi-Fi SM-T230, and the LTE SM-T235. While other variants can be also be found in there.
Choose the right stock firmware that correspond to your Galaxy Tab 4 model number. A firmware build for SM-T230 will not work on SM-T231 variants and vice-versa. It may contain a different kernel, bootloader and modem versions that result into soft-bricks. You may not also downgrade from 4.4.2 to 4.3 due to the secured bootloader. Like for example if you just need to unroot Sprint Galaxy Tab 4 SM-T237P then just grab Sprint Galaxy Tab 4 stock firmware that perfectly match with the current firmware build that you seen on the software version info. Same goes on to any other variants, just always used the pre-defined firmware build you have seen on your tablets software build details. You may recheck it again by going to Settings > About Device, then read the current firmware build number version on your tablet .
Step 4: Install the USB Driver and Extract the downloaded stock ROM
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 Tab4 into Download Mode
To reboot the Galaxy Tab 4 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 4.4.2 KitKat stock firmware for US Galaxy Tab 4 7.0 SM-T230NU.
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!!
Once the stock firmware installation successfully completed, 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 your fresh firmware installed by going on to Settings>About Device>Firmware info.
Re-configure your network APN Settings.
