wuzzupnshiat , the 2 SYSINFO.BIN are different files. The one in the Original folder is about 192bytes, while the other one in the FW folder is about 512bytes.
Perhaps you could try reloading your original firmware again, rename it, then see if the SYSINFO.BIN is both .\Original\ and as well .\Original\FW\
If these files are missing, i'll suggest to stop the procedure.
However, i would think that it might be alright to continue. As these files are your own original, and you are copying them to the new firmware.
So if your original firmware does not contain them, most likely the new firmware would not need them.
But again, it's your call to decide whether to risk it or not. Good Luck.
