So I just encounter it just now now and I found out the solution to unbrick it . It's quite simple so kindly follow this step. But first of all I tried to change my firmware from Jellybean euro version to Malaysia version. You see this is for unrooted phone. I never had an experience with rooted phone before. ( the main thing is try to find an original firmware) install it like when you're trying to install the root one.
All you need is this few things.
- Odin 3.07
- Samsung Galaxy S2 Official Firmware. ( Just to be safe)
So here are the steps
Step 1: Extract Firmware zip file that you downloaded already from above link, you will get a .tar.md5 file and some other files.
Step 2: Extract Odin zip file and you will get Odin3 v3.07.exe along with few other files.
Step 3: Power off your phone. Wait 5-6 seconds for vibration to confirm complete switch off.
Step 4: Boot the device into Download Mode by pressing and holding Volume Down + Home buttons together and then press the Power button until the device turns on. Now press the Volume Up button to enter Download Mode.
Step 5: Run Odin on the computer as an Administrator.
Step 6: Connect the Galaxy S2 to the computer using USB cable while it is in the Download Mode. Wait until Odin detects the device. 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:
- Select the PDA checkbox, and choose the file named .tar or .md5.
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.
Step 10: Once flashing completed, your phone will restart and soon you will see a PASS message with green background in the left-most box at the very top of the Odin. You can now unplug the USB cable to disconnect your device from computer.
