The tool will help flash the stock 4.1.2 firmware in the device. It is highly advised that you keep a proper backup of all important data because there are high chances that you may lose all the existing installed apps and personal settings during the process.
Users should also note that the tutorial will use I9305XXBLL3 Android 4.1.2 Jelly Bean, which may not be the firmware variant you have. However, the steps will be the same.

- Backup your data.

File Required:
1. Android 4.1.2 I9305XXBLL3 for Galaxy S3 I9305
2. Odin 3.07
Steps to Follow
Step 1: Extract the firmware zip file. You will get a .tar file and some other files.
Step 2: Extract Odin zip file.
Step 3: Turn off your phone and wait for vibration to confirm complete switch off.
Step 4: Place the Samsung Galaxy S3 I9305 in Download Mode by pressing and holding the Volume Down, Home and power buttons simultaneously until the Samsung Galaxy logo appears on the screen. Your device will be in the download mode in a short while.
Step 5: Launch Odin3 v3.07.exe as an Administrator.
Step 6: Connect the Galaxy S3 I9305 with your PC via USB. At this point, you will receive a message saying "Added" under the Odin's message box. In addition, if the device is connected properly, you will see the COM port with a number in Yellow.
Step 7: Choose the following files in Odin at relevant tabs from extracted I9305XXBLL3 firmware folder:
- Click the PDA Button and select the .tar file here with *code* appearing in its name
- Click the Phone Button and select file with *modem* in its name (leave if there is no such file)
- Click the CSC Button and select file with *csc* in its name (leave if there is no such file)
- Click the PIT Button and select the .pit file. Use this file only if you get it while extracting in step 1 or else just ignore it.
