Netherlands  (Vodafone) – VDF_9100XWLSD_I9100VDFLSC download link

Step 2: Prepare things  as follows:
- Use a PC or laptop that runs in Windows OS, with a good and perfectly working USB serial port.
- Use the USB cable wire for your Galaxy S2.
- Make sure that your galaxy S2 battery is fully charge.
- Back up all important files stored from your phone’s internal memory – contacts, messages, etc.
- Remember or back up the APN settings of your device.
- Enable USB debugging from your phone’s settings. Go to Settings > Applications > Development, and tick the box that says ‘Enable USB Debugging’.

Step 3: Extract or unzip the downloaded stock firmware so that you’ll get the Odin flashable .tar.md5 file. Use Winzip, winrar, 7zip or any extracting tool you had in your computer.
Step 4: Run and Configure Odin
Run Odin downloader on your computer’s desktop. Watch out the check-boxes options on the right top of Odin, ensure that the ‘RE-PARTITION’ is unchecked. Leave the ‘AUTO-REBOOT and ‘F.RESET TIME’  remains checked.
Now, click on the PDA button, then select and load the tar file that you have previously extracted. For example I’m using the  Italian firmware so I got the “I9100XWLSD_I9100VODLSC_I9100XXLS8_HOME.tar.md5″ 

Odin sample:
I9100XXLS8 odin stock install

Step 5: Reboot the Galaxy S2 into Download Mode.
To put your galaxy S2 in download mode, just simply switch it off then gently press and hold the “POWER, VOLUME DOWN and HOME” buttons simultaneously. You’ll be then prompted in a warning screen to continue or cancel.

Step 6: Connect the Phone to the Computer or Laptop
Once the phone screen shows in downloading mode, connect your phone to the PC with the USB cable. You’ll then notice the upper box in Odin that turns in yellow color., it also indicates the COM:ID where the device is being detected and a word “added!!’ on the log box. If somehow those things never showed up, check out the USB cable connection, read again from the top of this post.
Step 7: Flash it!
Once all set and ready, hit he “START” button to begin flashing.
Do not touch anything that might interrupt the process to avoid any fatal errors or failures, it may ruin your device if any interruption occurs while already in flashing status.

It may only takes about 3 to 5 minutes, depends of your PC/laptop speeds. A word “PASS” will display in Odin once it finishes. If somehow you will not get the word “PASS” or just stuck in along time. Disconnect the phone, remove battery, re-insert it, check the USB connection, re-install the driver, disable Kies and any anti-virus. Set the phone in Download mode again, and repeat the whole procedure.

The phone will just automatically reboots if the firmware flashing successfully completes. Just wait until it boots up on the “S” logo for a while then into an androidupdate screen. If it still shows boot logo try rebooting and if it stays there, you need to wipe your phone.

Fixing possible issues after flashing like bootloops or just stuck in welcome screen logo

Boot in recovery mode – Press and hold Volume Up, Home and Power button. Use volume keys to select up and down and power or home key to select the option.

1. Select Wipe Data/Factory Reset
2. Next select the Wipe Cache Partition
3. Lastly select Reboot System Now to reboot your Galaxy S2 in Normal mode.
Confirm your fresh firmware installed by typing *#1234# or
Go to Settings>About Phone>Firmware info.
Check and reconfigure your APN settings when data networks connection issues encountered.
