"can't open file "C:\Users\RUG\Desktop\setool2lite\rest\R4EK001 _CXC 1250316_GENERIC_HN""
See the patch got written succesfully but SET2 could not find the rest(ore) file .
After the break in is completed the rest file must be flashed because it is required to UNDO what the breakin loader did (which i believe is rewrite the first 4 line of the BABE header to what it was originally, do correct me if I'm wrong).
This did not happen since the REST file could not be found.
There is nothing wrong with the phone i believe, it was just that the setools.exe file couldve been moved out of its directory or some folders got misplaced.

This is my guess. :D
