Step 5: Run Odin on the computer as an Administrator.

When the device is connected successfully, the ID: COM box will turn yellow with the COM port number. Additionally, the successful connected will be indicated by a message saying Added. If Odin fails to detect the device then re-install USB driver.
Step 7: Choose the following files in Odin from extracted I9100DXLSD firmware folder by using respective checkboxes:

  • Click the Phone checkbox, and choose the file with 'modem' in its name (ignore if there is no such file)
  • Click the CSC checkbox, and select the file with 'csc' in its name (ignore if such file is missing)
  • Choose the PIT checkbox, and choose the .pit file. Use only the file obtained during extracting in step 1 above, otherwise ignore it.
Step 8: In Odin, enable Auto Reboot and F. Reset Time checkboxes. Also, ensure the Re-Partition checkbox is chosen only if a .pit file was chosen in the previous step.
Step 9: Verify everything suggested in Step 7 and Step 8 is done correctly. Then hit the START button to begin the flashing process.

  5. Just updated my trusty S2 to 4.1.2 using Honai's instructions and downloads above. This gives it another year or two of relevance, and I still luv the S2 square lines and light weight vs the roundish S3 and S4.
