Something happened to my samsung galaxy s2 recently* it wont connect to the sim network and it wont show the imei number. I have tried a lot to fix it and ended up finding out that there is no nv_data.bin and md5 files in the phone. But somehow i manage to get the nv_data.bin file back but its not in the folder where it should be and the phone can`t still locate it. Can you help me locate it where it belongs and maybe can you help me add new files or provide me with these files* if possible ? I think this will also restore my imei number* if i am not wrong.

i don`t know much but i am really annoyed and troubled due to this problem. Please help me !!! title=confused
