Was there a value after the SIGN= in the original file? That is the key to unlock the feature together with the HOST string:
FEATURE 503 agilent 1.000 permanent uncounted \
HOSTID=ID_STRING=12345678 SIGN=F1CE2A146BC6
The HOSTID is the ID of your instrument which is the same as in the file hostid in the same folder, and the SIGN is the key that was entered to activate the option.
Sometimes there are some default entries in there that don't have a SIGN so normally they do nothing. But when the patch is applied they all start to work...
Also, I see a hex "F0" value behind the sign for option 210 which I'm sure does not belong there, and a lot of hex "00" in every SIGN=

Try to put 12 digits (0-F) after every SIGN= and try again.
