Step 4: Then keep the phone as it is and connect it to your PC using the micro USB cable. Now just press Volume up button to continue. This will directly land your Galaxy S2 I9100 into downloading mode. Refer the screenshot below.
Step 5: On the PC, launch the downloaded ‘Odin Multi Downloader3-v3.12.7′ software which you’ve just received after extraction. As soon as you launch it, the ID:COM section located at the top left corner will turn light blue. Also an Added message will appear in the message box window. This will confirm that your Galaxy S2 I9100 has been successfully connected to your computer.
Note: If such thing doesn’t happen then it’s more likely to be problem with the mobile specific drivers. So just confirm whether you’ve properly installed the mobile specific drivers on your computer or not. You can install them via Samsung Kies or manually install them from the links given in the Pre-Requisites section. If the problem still persists try changing USB cable or the USB port.
Step 6: Next click on the Options tab located on the Odin window and tick the Auto Reboot and F.Reset Time options. Tick only these two options and keep all the other options as they are.
Note: Do not tick the Re-partition option as it may increase the risk of bricking your device.
Step 7: Now, click on the AP button present on the Odin window and browse to the firmware package file which you’ve downloaded (I9100XWLST_I9100ODDLSE_I9100DDLS9_HOME.tar.md5) and select it.
Step 8: Then initiate the firmware flashing process. To do so, just hit the Start button located on the Odin window.
Note: While the process goes on, your phone will boot itself automatically. Do not interrupt the firmware flashing process by disconnecting the micro USB cable from PC.
Step 9: Be patient and wait until the flashing process completes successfully. It will hardly take few minutes. When the flashing process completes successfully, the ID:COM section on the Odin window will turn green with the message ‘Pass’ on it. Also your Galaxy S2 I9100 will restart itself automatically. This will confirm that the official Android 4.1.2 XWLST Jelly Bean firmware has been successfully flashed on your Samsung Galaxy S2 I9100. Now you can remove the micro USB cable to safely disconnect your phone from PC.
Note: If this process fails or if Odin gets stuck or in case your phone gets stuck into boot loop, then close the Odin window, again go into downloading mode and implement the same procedure as given above.
