Hi Sir, how can I change or root my Samsung SHW-M250S to international version with updated Android version?

How can I change or root my Samsung SHW-M250S to the international version with updated Android version, because my problem is on text messaging they have 160 character limits ?

Check out the VisiHow article titled Bypass SMS Limit in Samsung Galaxy S2 (Korean Version). Try the suggestions from the article first before attempting to install OS on your device. As you can see in an above answer, the M250S version can be bricked when you attempt to install the International OS.

Where we can download all of the download tools to upgrade my SHW-M250 to Ice Cream Sandwich or Jelly Bean?

I downloaded ODIN, pit file and Samsung USB driver, but I can't find where to download the firmware.

You can download the firmware from this web page. This is Jelly Bean for SHW-M250K (Korean, KT olleh). You do not need other tools to upgrade your Samsung S2: you should have just ODIN, firmware, and, optionally, USB drivers for the Samsung phone if your OS fails to recognize it (please check our tutorial on how to upgrade your S2 to Jelly Bean).

Follow the process on how to update your Galaxy S2 to Jellybean 4.1.2 from this YouTube Tutorial. Keep in mind that using an older version of OS can cause conflict with some apps. Now apps are geared to operate on 5.0 Lollipop and higher.

Sensor not working issue, please tell me how to flash Korean M250 file and working sensor?

I'm converting my S2 SHW m250s vs i9100 and after that, the Sensor was not working. I flashed Korean version back, but it is not working

Hard reset the device. Then choose Wipe Cache Partition from the Recovery Menu. Your phone should work not but if it does not, then connect to Kies and use one of their diagnostic/recovery options. Switching back and forth between the different OS versions has caused conflict.

Is it safe to update firmware in my device?

I am using m250k I want to update my device but there is a problem it is of latest firmware

In the future, please be more specific with what the problem is. Is your phone now bricked or in a boot loop? Can you not make calls because the APN and IMEI settings are not assigned properly? After you upgrade OS, you should always put your phone into Recovery Mode and choose Wipe Cache Partition. Once the phone reboots, go back to Recovery and choose Clear Dalvik Cache. If you did not root your device, this also can cause issues if the ROM did not come from your cellphone manufacturers PC companion program or their website. You may also have tried to install a different Galaxy ROM that is not compatible for your device.

Power off the device. Then remove the battery and hold down both Volume buttons. You want to do this while still connected to the PC and Odin3 up on your PC ready to go. You need to be in Download Mode first, before you connect to Oding3 which is why it is taking so long for you.
