Before we can begin the installation of this firmware you will need to read the preparation guide and learn what actions you should take and by doing this you won’t be forced to repeat the tutorial more than once.

The Galaxy S3 I9300T was launched this month and multiple users already managed to install Custom ROMs and new kernels to improve their device’s overall performances. Also, some of these users said that some custom ROMs bricked their device and that now they would wish for a tutorial to teach them how to successfully restore a stock firmware that will help them repair their S3 phone. Now, before you start installing the stock firmware you need to read the pre-requisites guide info. Here’s what you need to know:

  • Android 4.0.4 ICS TDUALF 2 stock firmware works only with the Galaxy S3 devices with the model number I9300T. Don’t install it on US version or on any other device as it won’t work and you won’t solve anything.
  • install the Samsung KIES on your PC so that you’ll apply the Samsung USB Drivers. These are needed if you wish for your Galaxy S3 to be recognized while we’re installing the new firmware. If you don’t want to use KIES, then please use these direct download links for the phone drivers:  Samsung USB drivers for Windows 32bit (x86) OS version |Samsung USB drivers for Windows 64bit (64bit) OS version.
  • Enable USB Debugging on your phone and fully charge the phone’s battery until it goes over 70% so that your phone won’t power off while you’re installing the new firmware.
  • If you can boot your device, then you should backup the data you don’t want to lose. Please note that in case your phone is bricked then it means that you will lose all the files that aren’t stored on your phone’s internal and external sdcard.
  • apply the tutorial steps only if you’re an advanced Android user. Please note that we cannot be held responsible in case your device cannot be repaired or it gets worse and, that is why you should ask a friend who is more tech savvy to help you flash this stock firmware. Use the comments section to ask for our help in case you cannot install the files.

How to restore Galaxy S3 I9300T to stock Android 4.0.4 ICS TDUALF2 firmware:

  1. Download the TDUALF2 stock firmware zip file from here or here.
  2. Extract the file contained in the TDUALF2 zip and save it on your PC desktop. It should be a ‘.tar.md5’ file.
  3. Download ODIN3 v3.04 from here.

  6. Boot it into Download Mode. To do that you need to press ‘volume down’ + ‘home’ + ‘power’ buttons. Confirm that you wish to load download mode by pressing Volume Up when you’re seeing the phone’s screen booting up.
  7. Now launch ODIN executable and after that connect the I9300T device to your computer. ODIN will now display a message that tells you that the phone has been added. In case you don’t see such message then you should return to the preparation guide and install the Samsung USB Drivers. If everything went according to plan and download mode has been entered and all drivers are OK then you can move to the next step.
  8. When the Download Mode has been loaded on your phone, you should return to your PC and in ODIN click the button that is called ‘PDA’.
  9. Load the TDUALF2 file with the ‘.tar.md5’ extension, the one you’ve extracted at step 2. Click START in Odin and wait until all files are installed successfully. Do not change any default ODIN settings.
  10. That’s it, after you complete the installation, ODIN will reboot your device and you should disconnect it from your PC when the Samsung Logo appears. Now, ODIN should display a ‘PASS’ message and it means that all files where installed successfully. and your phone will boot into its stock ICS home screen.

If your device isn’t going past the Samsung Logo, then it means it got stuck and you need to remove its battery and after that re-insert it and boot the phone into custom recovery mode. To enter recovery mode you need to press the following buttons at the same time: volume up, home and power. Keep them pressed until the Samsung display boots up and recovery mode is loaded.

In recovery mode select ‘wipe data/ factory reset’ and after that you need to confirm this action. Now, select ‘wipe cache partition’ and confirm. Return to the main recovery menu and select ‘reboot system now’.
