Here’s what you need to download the official Samsung SGH-I747 firmware (stock ROM) flash file onto your computer. You can then use one of the compatible flashing tools to update the firmware on your smartphone or tablet.
Flashing tools were initially developed by the companies that were associated with the device’s hardware and were mainly kept in-house, adopted in the back rooms of smartphone repair centers to fix common mobile device-related problems. The tools were later published on the Web for anyone to use. Now you can solve the same kinds of issues that were once left up to those repair centers: bootloops, soft-brick situations, software errors, software bugs, update errors, so forth, by downloading the software onto your computer instead. What’s more, installing the Samsung SGH-I747 flash file is an easy task, thanks to the flashing tool’s user-friendly interfaces that usually require just one click before the flashing is underway.
Most third-party developers who create tools for helping you customize your devices—the teams that work on custom recovery images, rooting applications, et cetera—recommend sticking with custom software if you’ve already changed the system partition or replaced the stock recovery partition with a custom one. If you are to go back to stock Android on the device, though, they strongly suggest flashing the firmware yourself instead of accepting the over-the-air updates. This is because OTAs can create unexpected behavior since they’re often only patching over existing software instead of completely replacing it.
The flashing tools such as the Odin flashing tool are always computer applications. On most occasions, these apps are relatively small files that won’t take up much hard drive space.
You can sometimes have a choice of what flashing tool you want to use to flash the Samsung SGH-I747 stock ROM. You can flash Stock ROMs with tools that work for either the system chip found in the device’s hardware, the firmware file type, or on occasion, apps that are designed to work for a particular manufacturer. And depending on the file, there are times when you can flash firmware directly from the device’s recovery mode, too.

Note: The guide below works if your firmware file contains the tar.md5 file. If you ever need to flash Samsung firmware using the full stock ROM files individually instead, you can learn how to flash Samsung stock firmware using all four files. (Check your firmware file after you download it to see if it is a tar.md5 or comes as 4 individual files.)
How to Install Samsung SGH-I747 Flash File Using Odin
Note: the Odin flashing tool is straightforward to use, but it only works on the Windows operating system. You won’t get the flashing tool to load on a Mac or Linux computer. It doesn’t matter what version of the Windows operating system that you’re using as long as it is something above Windows XP.
1. Download and install the Samsung USB drivers on the computer if you don’t have them already.
2. Download the Samsung SGH-I747 stock firmware package from the links above directly to the computer. Extract the file by right-clicking on it and choosing the option to extract. When you do, you’ll see the tar.md5 file inside. That’s the file you’ll be using to do the flashing.
3. Download the Odin flashing tool. Any version should work, but the latest is the most up to date so grab that one. Extract the Odin file and then double-click on the Odin executable file (.exe) that is found from within the Odin folder after extraction. You should now have the Odin interface open on the computer and waiting for you to connect to it.
4. Boot the Samsung SGH-I747 mobile device into the Download Mode by first powering it down and then rebooting by holding the “Volume Down + Home + Power” keys at the same time.
5. A yellow warning triangle will come up on the device’s display. At this time you need to press the “Volume Up” button. You’ll then see the device getting into the Download Mode. It’s then ready for the flashing.
6. When in Download Mode, connect the Samsung mobile device to the computer with the USB cable.
7. If you have installed the USB drivers correctly, the Odin flashing tool should detect your device. You can tell this by observing the ID: COM port lighting up with a color, usually yellow or blue. (It doesn’t matter what color, it’s the lighting up that counts.)
8. After the device is picked up by Odin, click on the “PDA” or “AP” button, depending on what button your version of the Odin flashing tool has.
9. Navigate to the stock ROM folder and upload the tar.md5 file to this location in Odin.
10. Without changing any of the default settings, click on the “Start” button in Odin, and the flashing then begins.
11. Wait until Odin shows a “Pass” message before disconnecting your device.
Back Up Your Data: You should always back up your data before you begin flashing new firmware files to your Samsung smartphone or tablet. All of your pictures, music, videos, documents, etc. should be still on your device after you have updated the firmware, but you may need to restore the contacts and applications from a backup.
Wipe Cache and Factory Reset: Some people claim that taking a factory reset isn’t necessary after updates, but at the very least you should wipe the system cache after installing new firmware. This way you can help eliminate any performance issues and battery draining bugs. Taking a factory reset is the best way of avoiding common problems many users face after applying software updates.
You can download Android ROMs for other Android devices if you have another smartphone or tablet from a different manufacturer.
