Probably the problem is that you don't have the required rest file:
So first you need to make the R4EA031_CXC1250316_GENERIC_HN rest file with ssw2rest.exe located in [SeToolLite_folder]\make_rest\ folder(in your case C:\Documents and Settings\Desktop\Phone\setool2lite_1.11\make_rest\ ).can't open file "C:\Documents and Settings\Desktop\Phone\setool2lite_1.11\ rest\R4EA031_CXC1250316_GENERIC_HN"
