How to Unroot and Get the Samsung Galaxy S Blaze 4G Back to Stock (SGH-T769)

If you have rooted, installed custom ROMs/recoveries and for any reason, need to take the device into a service center, getting it back to stock is a good idea.  The post below will help you do that with the Galaxy S Blaze 4G, so read on if you want to know how.

I.  Before You Begin

1.  Back up everything you feel is important before you begin as this will replace your existing firmware with the stock version.

2.  Make sure that you have your device charged to 75% or more before you begin to prevent problems during the procedure.

II.  Necessary Downloads

1.  Odin 1.85.rar

2.  blaze.pit [Available as the Download Pit link in this post]

3.  SGH-T769-UVLB7-k0nane.7z [Available as the Download Stock TAR link in this post]

III.  Unrooting the Samsung Galaxy S Blaze 4G

1.  With your device connected to your PC via a compatible microUSB cable, power down your device and remove the battery.

2.  Still connected to the PC, reinsert the battery, and press and hold the Volume Down + Volume Down + Power buttons until your device boots into Download Mode.

3.  Extract SGH-T769-UVLB7-k0nane.7z to a folder on your desktop.  You should end up with a file called SGH-T769-UVLB7-hitsquad.tar.

4.  Extract the Odin 1.85.rar file you downloaded above to a folder on your desktop.

5.  From the extracted folder, double-click on Odin3 v1.85.exe to run the tool.

6.  Click on PDA button, locate SGH-T769-UVLB7-hitsquad.tar and click on OK to load it on Odin.

7.  Click on the PIT button, locate the blaze.pit you downloaded above and click on OK to load it on Odin.

8.  Connect your device to your PC using the USB cable.  Odin should now recognize your device and light up the ID:COM field yellow to signify this.  If not, reinstall the proper drivers and try again.

9.  Make sure that only the Auto Reboot option is checked and Re-Partition, Flash Lock and F. Reset Time are unchecked; this is important as you might brick your device if these options are ticked!

10.  Click on Start.

Once Odin says PASS and your device reboots, your Galaxy S Blaze 4G should be back to stock!

    after all this how can i unlock network code

    • Dax Krishna

      Hi,

      If you were unlocked previously, nothing you do after that like rooting, flashing custom ROMs will affect that and you will remain unlocked! if you are not unlocked previously though, you could contact your carrier for the unlock code or use the unlock services available on the web to unlock safely

      • Carlos Dorado

        but you have to be in stock rooted rom in order to get the unlock code it will not work with any other moded roms

    Dax or Mahesh,
    Ive been wanting to unroot my phone because rooting it has caused small annoying problems. I was going through all the steps and I was suck on
    8. Connect your device to your PC using the USB cable. >>>Odin should now recognize your device and light up the ID:COM field yellow to signify this<<<. If not, reinstall the proper drivers and try again.
    It seems that the phone is not in download mode, it goes into the "CWM – based Recover v5.5.0.4" I have the options to reboot the system, install zip from card, wide data, wipe cache, back up or restore, mounts and storage, or advanced. I have navigated those menus and found no way to put the phone in download mode so i can see the ID:COM field turn yellow. Please help me fix the problem if you can. Thank you very much.

      It looks like you’re being booted up into the Recovery Mode whereas you’re supposed to be in Download mode.

      If the key-combination doesn’t work and you’re unable to boot into Download mode, then try out the following steps and it should do the job. (Windows only, no Mac and Linux!)

      (1) Download Fastboot from here – http://goo.gl/zZOJW

      (2) Extract files from the Fastboot archive to your Desktop and you’ll get adb.exe along with some other files.

      (3) Enable the USB debugging function on your device by simply heading to Menu>>Settings>>Applications>>Development>>USB debugging.

      (4) Once enabled, connect your device to your PC via USB cable.

      (5) Launch a Command Prompt Window on your Desktop. To do that, simply hold down the Shift button on your keyboard and right-click on any empty area on the screen, then select Open command window here.

      (6) In the Command Prompt Window that you just opened, enter the following command:

      adb reboot download

      (7) And your device will reboot into the Download mode.

      That’s all.

      Hope it helps you to get into download mode and unroot your device.

      Thanks!

        can adb put my device into recovery mode?? key combination wont work and need to wipe my phone clean.

      • Andy Rogers

        Most folks forget to mention that unless you have the usb cable plugged into the pc and one phone is off connect it to the phone and follow the steps it should boot in download mode.

      • Showster

        I just wanted to leave a message, i was fighting with this for nearly two hours because none of them addressed that i needed to be in download mode not recovery mode.
        Thank you.

  • FH

    Is the stock ROM mentioned the correct version for the Dec 2012 Blaze version? I am unable to get past the Android setup screen. Getting reoccurring errors such as ‘Google Applications Service Framework stopped working and androi.process.acorestopped unexpectedly. Help!

    • Cassie

    • Mahesh Makvana

      You can download an app called “Quick Boot” from the Play Store to get your device into the Download mode.

      Thanks!

  • FFurcs

    my TAR (SGH-T769-UVLB7-k0nane.7z) isnt showing up in my files when i click PDA in odin mode. help please

    • Mahesh Makvana

      You need to unzip that archive to get the actual TAR file. You can use free tools like WinRAR to extract such archives.

      Hope it helps!

  • Sam Uhlarik

    Thank you so much for making this tutorial!!! Without you I would’ve gone to the T-Mobile Store and they wouldn’t fix my phone because I didn’t follow the directions when I rooted my phone and it would only turn on in download mode. You’ve saved me from buying a new phone!!!!!! Thanks again!
