Update Galaxy S3 SHW-M440S to Android 4.3 KSUGMK2 Official Firmware
As this tutorial progresses, your Galaxy S3 SHW-M440S will slowly but steadily be updated to Android 4.3 with KSUGMK2, official firmware launched in November this year.
The upgrade for your smartphone comes late, considering the launch of the handset, which was July last year. But even if the new firmware has just been released, you will still get great results after it’s flashed on your phone.
Which, by the way, should be a South Korean version to properly accept the Jelly Bean 4.3 KSUGMK2. And it should run a custom ROM already besides being the Galaxy S3 M440S model; be sure to only use our tutorial on the version we told you about, because if your phone is another model, you risk bricking it.
The KIES logo on this firmware isn’t activated. Which is good news, because if you can’t or don’t want to use our guide or the OTA method (the Software Update button under Settings menu), you can update your phone with KIES instead.
If your smartphone isn’t rooted, no problem; but if the device is rooted, the main problems will be the following: the update will affect the system partition and the root access present on your handset will be revoked. But the important content and the internal / external SD cards will not be deleted or damaged.
The latest Android 4.3 update makes sure there are no bugs on your phone after the update is performed and that the Galaxy S III SHW-M440S is going to deliver an excellent performance.
A list containing all the important pre-requisites is coming your way:
- click here, look for USB drivers meant for your phone and flash them on your laptop or PC;
- create a standard backup and a NANDroid one;
- make sure your phone’s battery is fully charged;
- disable, for now, your notebook’s and phone’s security programs;
- turn on USB Debugging;
- your laptop or personal computer must sport Windows.
- A very important part of this tutorial is when you download, on your notebook or PC, the next two packages: the new Jelly Bean firmware and Odin tool, available here.
- You will be asked to unzip them after they are on your device and then to enter the M440S in Download Mode. The latter is very easy to boot into: all you have to do is press and hold, together, Volume Down, Power and Home, then press Volume Up to end up in the Download Mode.
- Proceed to the next step which needs you to open the Odin as Administrator on your laptop. Then take the USB cord of your phone to create a connection between it and the laptop.
- Wait until the Odin recognizes your handset, which means that you should run into an “Added!!” message together with an ID:COM box which should be yellow. In case there’s no plugging shown, you have to consider one of these solutions: flash the USB drivers again or resort to another USB port.
- As soon as you experience a successful plugging, you can go on to the next step. Which, in this case, prompts you to tap PDA, choose a file with a CODE appearing in its name, tap Phone, select a file with a MODEM showing up in the name, click on CSC, opt for a file with CSC in the name, click on PIT, choose a file that features .pit as the extension.
- The next step: check these couple of boxes: Re-partition, F. Reset Time and Auto Reboot, after which make sure to continue to the step that requires you to tap “Start“.
- The Jelly Bean 4.3 KSUGMK2 stock firmware will, in a few seconds, find its way to your smartphone. After the installation is finally complete, you will have to wait for the phone to restart; when a message that reads “Pass” in green pops up on the screen, you will know that the following needs to happen: disconnect the two devices from one another by removing the USB cable.
If you have no clue where the new firmware is, we recommend the following method: access Settings, then tap About Phone on your Galaxy S3 SHW-M440S. Now that your smartphone is updated, feel free to leave a comment in the field below; in case you run into trouble, let us know.
The update firmware we used today may not rise to your expectations. If so, you should do this: use the NANDroid backup file. Do that by revoking the update with this file. The phone’s old ROM will soon afterwards be restored.
