How to Update Galaxy S2 GT-I9100 on Official Android 4.1.2 VJMS4 Jelly Bean Firmware

Galaxy S2 I9100 Receives Official Android 4.1.2 VJMS4 Jelly Bean OTA Update

Step 1: Extract the firmware zip file to the desktop to get a .tar.md5 file and some other files (optional).

Step 2: Extract Odin zip file to obtain Odin3 v3.07.exe along with few other files.

Step 3: Power off the phone and wait for vibration (about 5-6 seconds) to confirm complete device shutdown. Now boot the phone into Download Mode by pressing and holding Volume Down, Home and Power button together until a construction Android robot icon with a triangle appears on screen. Then hit Volume Up button to enter Download Mode.

Step 4: Launch Odin3 v3.07.exe that you obtained in Step 2 as an Administrator, as Admin privileges are required to complete the firmware installation process smoothly.

Step 5: Connect your phone to computer via USB cable. When the device connects successfully, the message saying "Added!" appears in ODIN and the ID: COM box will turn yellow with the corresponding COM port number. If the message fails to appear, try reinstalling the phone's USB drivers or changing the port on the computer.

Step 6: Choose the following files from I9100VJMS4 folder that you obtained in Step 1 in Odin using respective checkboxes:

Select the PDA checkbox, and click the .tar.md5 file
Tap the Phone checkbox, and select the file named 'modem' (ignore if such file is not found)
Choose the CSC checkbox, and click the file named 'CSC' (ignore if there is no such file)
Click the PIT checkbox, and choose the '.pit' file (ignore if the file is missing)

Step 7: In Odin, enable Auto Reboot and F. Reset Time options by selecting the checkboxes. But the Re-Partition checkbox must be selected only if a .pit file was chosen in the previous step in ODIN.

Step 8: To prevent ROM related errors, verify Step 6 and Step 7 are done correctly. Then hit the START button to begin flashing the firmware.

Step 9: Once the firmware installation is complete, the phone will reboot automatically and soon a PASS message with green background appears in the left-most box at the very top of Odin. Now it is safe to disconnect the USB cable to remove the device from computer.

The Galaxy S2 GT-I9100 is now running on the latest Android 4.1.2 VJMS4 Jelly Bean OTA firmware. Go to Settings > About Phone to verify the firmware installed.

Troubleshooting:

If the phone is stuck at boot animation or Samsung logo after Step 9, then go torecovery mode (press and hold the Volume Up, Home and Power buttons together) and perform Wipe data/Factory Reset as well as Wipe Cache Partition before choosing reboot system now option. Use Volume keys to navigate between options and Power key to select an option in recovery. Please note that performing data wipe task will only erase your phone's internal memory and not the data on SD card.
