Korean Galaxy S2 SHW-250S/K 4.1.2 Jelly Bean Official Update Convert to GT-i9100
Korean Galaxy S2 models have model names depending on their carrier. The last letter indicates the carriers such as SK, KT, and LGT. So there are three Galaxy S2 models, SHW-250S, SHW-250K, and SHW-250L. All of them have similar specifications, 1.2 Ghz Samsung Exynos dual core CPU, 1Gb RAM, 16Gb Storage, DMB (Digital Media Broadcasting), and NFC (Near Field Communication).
So the only Korean Galaxy S2 models from SKT and KT can run GT-I9100's firmware and actually work.
Before I begin, there are few things needed to change the firmware of SHW-250S/K to GT-I9100.
- SHW-250K or SHW-250S ( At least 40% battery left)
- Micro USB cable
- PC with drivers for SHW-250K/S installed
- GT-I9100 Firmware
- ODIN software Odin3 v3.04

How to Install Official Android 4.1.2 XXLSJ Jelly Bean Firmware on Galaxy S2 SHW-250S/K
Step 1: Download Android 4.1.2 XXLSJ Jelly Bean Official firmware
Step 2: Extract the downloaded firmware zip file to the desktop
Step 3: Extract Odin zip file to get Odin3 v3.07.exe as well as few other files.
Step 4: Power off the phone and wait for vibration (about 5 to 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 progress into Download Mode.
Step 5: Launch Odin3 v3.07.exe that you obtained in Step 3 as an Administrator, as Admin privileges are required to complete the installation process smoothly.
Step 6: Connect the phone to computer via USB cable. When the phone is connected successfully, Odin's message box says "Added!" in the bottom left of the screen. If the message fails to appear, then try another USB port (preferably the one at the back of your desktop computer). If all else fails, just re install the phone's USB drivers on computer. Once the "Added!!" message appears in Odin, you can proceed to the next step. At this point, the ID: COM box will turn yellow with the corresponding COM port number suggesting that the device is added successfully.
Step 7: Choose the following files from I9100XXLSJ folder that you extracted in Step 2 using respective check box options:
In Odin
Step 8: In Odin, enable Auto Reboot and F. Reset Time options by selecting the respective checkboxes. But, ensure that Re-Partition checkbox is chosen, only if a .pit file is added in the previous step in ODIN.
Step 9: Verify if Step 7 and Step 8 are done correctly. Then hit the START button to begin the flashing process.
Step 10: Once the firmware installation is complete, your 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, safely unplug the USB cable to disconnect the device from computer.
