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 .

    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.

Important Note:

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

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 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.

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.
