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
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. Power down your device and remove the battery.
2. 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!
