Instructions

Extract the contents of the ZIP package to your computer. You should get the following files after extraction:
- I9100XWLPT_I9100XXLQ6_I9100XEULPA_HOME.tar.md5
- Odin3_v3.04.zip
Extract the contents of the Odin_ v3.04.zip file to a folder on your computer.
If your phone is still connected to the computer, disconnect it.
Turn off your phone.
Place your phone into Download Mode by holding and pressing the Volume Down, Home, and Power buttons together until a “Warning!” message appears on the screen. Press the Volume Up button to enter Download Mode.
Double-click on the Odin3 v3.04.exe file you've obtained from the extracted ZIP file to launch Odin on your computer.
Connect your phone to the computer. You should see an “Added!” message in Odin.
In Odin, click the PDA button and locate the *.tar.md5 file and select it. Note that the *.md5 extension may be hidden, depending on your computer's settings, so you might only see the *.tarextension.
- NOTE: Do not change anything in Odin. Leave everything as is except for selecting the file in this step. Make sure the checkbox beside “Re-partition” under Options is NOT CHECKED.
Click on the Start button in Odin to start flashing the firmware to your phone.
Once the flashing is done, your phone will automatically reboot. You'll see a “PASS” message in Odin and you can safely disconnect your phone from the computer once you see the Samsung logo on your phone's screen.
- NOTE: If Odin gets stuck or you get a “FAIL” message after flashing the firmware, disconnect your phone from the computer and close Odin. Remove your phone's battery, re-insert it, and do the procedure again from step 5 onwards.
If your phone gets stuck at the booting image when it reboots after getting a “PASS” message in Odin, do the following steps:
- Turn your phone off and remove your phone's battery. Re-insert the battery, wait for 5 seconds, and boot your phone into Recovery Mode.
- Select Wipe data/ factory reset and confirm the action on the next screen.
- Select Reboot system now after wiping data. This will help boot your phone properly to the newly installed firmware.
