Step 1: Important Reminders before Flashing Stock ROM to Unroot Verizon Galaxy S3

  • Make sure that your Galaxy S3′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 S3.
  • Enable USB debugging from your phone’s settings. Go to Settings > Applications > Development, and tick the box that says ‘Enable USB Debugging’.
  • Ensure that KIES is closed 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

Grab your Verizon Galaxy S3 Original Firmware or Stock ROM
What is a Stock ROM?
Stock ROMs are the firmware that has been released from Samsung Kies official firmware server. These are being pulled from Kies by an Android firmware experts and carefully re-bundled it to make it flashable by using Odin flasher tool. This is useful to create custom ROMs, root kernels, fixing bricked devices, unrooting and restoring back to original factory firmware.

Factory Stock/Firmware: Choose SCH-I535 Stock

Step 3: 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 4: 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 5: Reboot your Galaxy S3 into Download Mode

To reboot the Galaxy S3 into  download mode , you need to turn the power off.  After it completely shut off,  just  press and hold the Volume Down key,  Home button 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 6: 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 7: 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 show flashing the Android 4.1.1 Jelly Bean stock firmware I535VRBLK3.
example: I535VRBLK3_I535VZWBLK3_381038_REV09_user_low_ship_NOWIPE_FIXED.tar.md5

Step 8: 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 9: 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.

Confirm if you successfully unroot your Verizon Galaxy S3 (SCH-i535).

Confirm your fresh firmware installed by typing *#1234# or
Go to Settings>About Phone>Firmware info.
You can also do factory reset by dialing *2767*3855#.

Possible errors that you may encountered, this is based on my own experience while flashing stock ROM on Samsung Android devices. These are just a few hints on how to resolved it.

Q: I got an error message that says “Set-up connection Failed” ?
A: 1. Check your USB connection from the phone to PC,
2. Connect to another PC USB port
3. Check and try to another USB cable
4. Re-install the USB driver.
Q: Odin just suddenly stuck in the middle of nowhere while in flashing progress, It isn’t responding at all?
A: Check for possible program that might interrupt the process, like disabling the anti-virus and closing any running programs.
Try to use another PC or laptop,
Q: I experienced bootloop or the phone just stuck on Welcome Logo (phone always stop at bootanimation) and it won’t boot normally?
A: You can fix it via recovery mode option, do this:
Boot in recovery mode
1. Press and hold Volume Up, Home and Power button.
2. Use volume keys to select, Up and Down and Power or Home key to select the option
3. Select Wipe Data/Factory Reset using the Home button.

    Thanks! This worked well for me! Appreciate your help!

  2. Cass says:

    Potentially dumb question: does a stock, never rooted, never rommed i535 have that yellow triangle sign with the exclamation point when it’s booted into download mode? I have used triangle away and reset the flash counter and reflashed back to stock. Everything else looks good…

    ODIN MODE
    PRODUCT NAME: SCH-I535
    CUSTOM BINARY DOWNLOAD: No
    CURRENT BINARY: Samsung Official
    SYSTEM STATUS: Official
    QUALCOMM SECUREBOOT: ENABLE

    It’s just that stupid yellow triangle that is throwing me off. I haven’t found any reference as to whether that’s an indicator to Verizon that the count has been tripped or if it’s just a general warning for everyone.

    Thanks!
    Cass

    • Kim Bubble says:

      That’s a warning sign just to remind everyone that flashing roms and rooting are risky. your CUSTOM BINARY Counter says No and official. It means your bootloader is now locked, that will appear if you forgot to unlock your bootloader before flashing a rom, kernel, custom recovery.

  3. Joel says:

    I know it’s always a good idea to back up everything just in case, but does this method in theory leave all data and settings untouched if all goes well? I’m looking to unroot and roll back to 4.1.1. Would it make a difference if I load the stock firmware through CWM?

    • Kim Bubble says:

      CWM is a convenient way for rolling back to previous versions for it has an easy back-up option. Odin stock firmware can’t be installed through CWM but you can use any OTA update.zip instead. To gain a 100% clean stock, you should also remove CWM by flashing the official recovery (stock recovery).

  4. rainytonite says:

    I’m failing at the last step on Odin, it’s giving me “Complete(Write) operation failed.” I followed and used all the links listed. I do have a count 1 on the binary, but not concerned (or really can’t do anything cause I cannot boot into my phone with triangle error saying system software is not authorized. Any help would be appreciated :)

  5. Mike says:

    Everything seemed to work but then it won’t go pass the 4G LTE animation on bootup. I restarted but I can’t get into recovery mode,I can only get into download mode. Can you help?
