If you dabbled in the custom scene and opened up your device internals with root access, you might want to put those same restrictions back in place again. Luckily there are third-party developers out there who make that possible with dedicated tools to get you back on stock Android and where you want to be.

When you do unroot the Samsung Captivate Glide smartphone, you are going back to the same stock ROM that you had when you first bought the device and opened it up out of the box. Nothing will be different. If, however, you were to have installed a custom recovery image, then you would have had to unlock the bootloader, and after you unlock the bootloader your Android operating system always lets you know about it after you boot it up so it’s not the same and it is obvious that your device has been tinkered with. It is possible to lock the bootloader again, but it isn’t always as simple as it sounds, so make sure you know what you’re doing if you decide to unlock the bootloader. It pays to take a few extra minutes to make sure you can handle the guide for locking it back up again.

BEFORE YOU BEGIN 

  • There are several different variants under the Captivate name. You should only be following this tutorial if you have the Glide version.
  • You need to have a Windows computer or laptop which runs Windows XP and up. Do not try running the Odin tool from Max or Linux computer as Samsung only make it for Windows.
  • The following does not void the warranty.
  • You should have a device with root access before starting.
  • Make sure you enable USB Debugging mode from the Developer Options menu. Tap on the build number seven times from the “About Device” menu available from the Settings to unlock the Developer Options if it needs unlocking.

HOW TO UNROOT THE SAMSUNG CAPTIVATE GLIDE

  1. Download the official stock Android firmware build from here.
  2. Download the version of Odin you can use here.
  3. Extract the Odin folder to the desktop and run the tool.
  4. Boot the smartphone in Download Mode.
  5. Hold the Volume Up + Power at the same time, and the phone should boot into the Download Mode.
    Now connect the device to the computer using the USB cable.
  6. Click the PDA button from inside Odin and browse for the stock firmware file.
  7. You will need to unzip and extract the firmware folder to find the executable firmware file inside.
  8. Leave the default settings as they are.
  9. Do not check the re-partition box.
  10. Click the Start button to start the flashing.
  11. Do not touch any buttons until it completes.
  12. You’ll find Odin giving you a pass message, and the device will automatically reboot.

Now your phone is free from root access and running the stock version of Android both Google, and your manufacturer intended. Furthermore, the warranty on your Captivate is in working order so long as you have some time left. Everything should work on your phone the same way as it did before you got root access to begin with. If you find that is not the case and your stock ROM has some bugs, then you might want to try to find another stock ROM that is perhaps a newer version of Android. Only download your future stock ROMs from trusted sources; that can be blogs, at times, but make sure the blog looks legit, has professional writers, and is rolling out unique content and not just copied content. You can find that out by copying and pasting some of the webpage’s text into Google and seeing what the search results show. If it’s the only website coming up for that text then it’s original content.
