Install Official Android 4.1.2 on Galaxy Grand I9082

Step 1: Download Android 4.1.2 I9082XXAMC7 official firmware for Galaxy Grand I9082 on the computer and extract the zip file.
Step 2: Download ODIN v1.85 which is required to install the official firmware on the phone.
Step 3: Turn off the phone and boot it into Download Mode. To do so, press and hold Volume Down and Home buttons together, and then tap the Power button until the construction Android robot icon with a triangle appears on screen. Hit the Power button again to confirm entry into Download Mode.
Step 4: Launch ODIN on computer and connect the phone to it while the phone is still in Download Mode.
Step 5: When the phone connects successfully, one of the ID: COM boxes turns yellow with the corresponding COM port number. This process may be time-consuming and take about five minutes to complete. So, please be patient.
Step 6: Now choose the files that need to be flashed or installed on the phone, which can be found among the extracted files in Step 1.
    • Click the 'PDA' checkbox and choose the file with 'tar' or '.md5' in its name.
    • Select the 'Phone' checkbox and choose the file named 'MODEM'. Ignore if there is no such file.
    • Choose the 'CSC' checkbox and click the file named 'CSC'. Ignore if such file is missing.
    • Click the 'PIT' checkbox and choose the .pit file. Ignore if such file is absent.
Step 7: In ODIN, enable Auto Reboot and F. Reset Time options. But, the Re-Partition option must be checked ONLY if a .PIT file was chosen in the previous step.
Step 8: Now hit Start button in ODIN and the firmware installation process will begin. Wait for a few minutes until the process completes.
Step 9: Once the firmware installation completes, the phone will reboot automatically. When the home screen appears, just disconnect the phone from computer.
