How to Unroot Galaxy S4 I9500 by Flashing Official Firmware
1. Extract the downloaded firmware zip file to get a .tar.md5 file and few other files.
2. Extract Odin zip file to receive Odin3 v3.07.exe along with some other files.
3. Turn off the phone and Wait for vibration (about 5 to 6 seconds) to confirm complete device shutdown.
4. Now, boot the Galaxy S4 I9500 into Download Mode by pressing and holding Volume Down and Home (center) buttons simultaneously and then long press the Power button until a message prompts the user to press the Volume Up key to continue.
5. Now launch Odin3 v3.07.exe (see Step 2) as an Administrator as Admin privileges are required to complete the unroot process smoothly.
6. Now connect the phone to computer with USB cable. A message reading "Added!" appears in Odin's message box at the bottom left of the screen. If the message fails to appear then just try another USB port (preferably the one at the back of the computer). If all else fails then just reinstall the USB drivers for the phone on computer. When the successful "Added!!" message appears in Odin proceed to the next step. At this point, the ID: COM port with a number turns Yellow if the device is added successfully.
7. Choose the following files in Odin from extracted I9500XXUAMDE firmware folder by using respective checkboxes:
- Select the PDA checkbox, and choose the file named .tar or .md5.
- Click the Phone checkbox, and choose the file with 'modem' in its name (ignore if there is no such file)
- Click the CSC checkbox, and select the file with 'CSC' in its name (ignore if such file is missing)
- Choose the PIT checkbox, and choose the .pit file. Use only the file obtained during extracting in step 1 above, otherwise ignore it.
8. In Odin, enable Auto Reboot and F. Reset Time checkboxes. Also, ensure the Re-Partition checkbox is chosen only if a .pit file was chosen in the previous step.
9. Verify everything suggested in Step 7 and Step 8 is done correctly. Then hit the START button to begin the flashing process.
10. Once the flashing completes, the phone will reboot and soon a PASS message with green background appears in the left-most box at the very top of Odin. Now unplug the USB cable to disconnect the phone from computer.
Congratulations! Android 4.2.2 XXUAMDE Jelly Bean official firmware is now unrooted on Galaxy S4 I9500. However, to restore warranty first install triangle away app to reset flash counter to zero and then follow the above steps.
