Znalazłem coś takiego (poniżej) i po wgraniu Odin-em ,pokazała się partycja EFS tylko że nie ma dalej mojego IMEI i fon nie widzi Sim.
OK, So How do I restore /efs if I dont have a Backup?

Press Volume Up to continue when asked
Download Odin.zip on your PC
Extract Odin.zip with Winrar and open Odin.exe file (the file with a blue icon)
Connect Phone to PC with USB Cable
Wait for some 15 seconds and see if COM(number) port has come in Blue colour
