I found that in my scope the code sequence was different. I thought that was just the MSO, but it's worth a try. Look for 0x02 0x00 0x84 0x00 0x10 0x00 with a hex editor.

See my description at:

Thanks edgelog, I had already tried,
but I probably did not clean up the old compilation,,,,
I tried again now and bamm found the codes !!!!THANKS!!!!!
For now I can not try the codes I have to wait 12h .....(too many try)

I discovered other 5 codes in my dump!!!!,
using the simple command(on OSX, but i think is the same on Linux):
strings -n 28 dump.bin >> dumpoutput.txt
you will find so many text (in dumpoutput.txt), but if you have patience you will find other codes without use rigup (two at the end of file (dumpoutput.txt) other in the middle)
I tried just one and in one shot enabled all the options except 100M bandwidth !!!!!! :-+ :-+ :-+ :-+

PS Thanks Again edgelog!!!!
