[SOLVED] Problem on SWH M250S Korean mobile.

[prak5192]

Hello friends,
I bought one Samsung galaxy S2 from south Korea. having model number SWH M250S.
I live in India, So I wanted to converted it into GT-I9100, SO flashed with Indian firmware which i downloaded from samfirmware.com.
Now actually I have one major problem and two minor problem.
Major Problem.
===============
I have no mobile signal or you can say very less signal on my phone. On average, In 24 hour it I can say it is available on phone for just two hour.This problem persist with both the firmware. ( Korean and Indian).
Also I am little bit confuse on Antenna side of Korean Galaxy S2.
In International or Indian galaxy S2 I am not seeing any antenna wire or cable which you can pull out. The antenna is internal a log wire type which is connecting from top to bottom,( I saw in youtube video) But In Korean galaxy S2 I can see one cable on the right top corner of the phone. Is this is the antenna used for network signal catching or it is used for TV antenna.

I am totally confused that it is a hardware problem or software problem.

Minor Problem
===============
1. Messaging is restricted to 80 character only in Korean firm, but this is getting over when I am flashing a Indian firmware.
2. The screen lock option is not coming after enabling the option in setting , and power key is not displaying its usual options like restart, shutdown, flight mode. For this I read in this http://forum.xda-developers.com/showthread.php?t=1899309 , that i have to be root to get this option. But i tried it and it was not displaying those options ( May be I am doing something wrong.)

The Minor issue is ok.. I am not bothering too much On these, but please friends help me on solving the major one.
It looks like I am carrying a PDA instead of a phone.

Thank you

1st, please change your thread title.. it is a question, so instead of [Guide], it should be [Q]

But anyway, your model is SHW-M250S and it is different with the model GT-I9100. You should not flash any GT-I9100 firmwares, only SHW-M250S..

There is no way to convert your model to GT-I9100, only mod it.. i believe there is a thread somewhere in the General section with the same model as yours. Perhaps checking it there would be your best bet
