Is there any progress in unlocking the MSO1104z?

I would also be very interested in an option to unlock all features of a MSO1074z, its essential for my decision if to buy one or not.

Hi..

Any luck with hacking MSO1104Z & DG1000Z (memory option)?

Thanks

I can confirm that Rigup 0.04 is not working for the latest batch of ds2072a scopes.  I received mine last week and received the 'upgrade unavailable' message on ver 3 firmware and ver 2 hardware.  I tried for 300mhz and 200mhz with no joy.  I think we are going to need a new keygen.

By the way, the page at http://gotroot.ca/rigol/riglol/ , what is that very long key it generates after you enter your serial, option, and private key and what are you supposed to do with it?

To all you MSO1000Z Owners: It's done, we found what Rigol changed for the MSO1k and we patched rigup to generate working keys.

Usage: Well, get the file, compile the source, call rigup like this:

--- Code: ---./rigup license mso1074z.txt 0x1C0FF
--- End code ---
Note: The License option *must* be supplied as hex, these are valid values:
0x1C001 - TRIGGER
0x1C002 - DECODER
0x1C004 - MEM-DEPTH
0x1C008 - RECORDER
0x1C00F - All of the above

There are also these options, but they will modify your scope into a MSO1000Z. They are mostly untested and might harm your children.
0x1C010 -
0x1C020 -
0x1C040 -
0x1C080 -
0x1C0FF - all Options

Generate the mso1074z.txt like this:

--- Code: ---./rigup scan YourDump.bin > mso1074z.txt
--- End code ---

Note: You will need to open the scope to get a dump. I'm not going to change that, but if anyone of you would like to reverse the firmware signing process, there is a hidden DBGCMD that might provide useful as an entry point for custom SCPI logic.

I want to thank rmd79 for his continuing efforts as well as all original authors of the rigup tool! You guys are the one who deserve any credit!
Also, thanks to sptm14 for you keeping all the info from the public. This motivated me to actually walk through their code!

Best regards,
Fabian

Great work :)

The only thing I had to do was edit the main "Makefile" and change:


--- Quote ---LDFLAGS                 := -O2 -Wl,-dead_strip

--- End quote ---

back to the original line:


--- Quote ---LDFLAGS                 := -O2 -Wl,--gc-sections -s

--- End quote ---

Otherwise when running rigup license I would get the command-line help screen and then a segfault.

Other than that issue, its generating valid keys for my MSO1074Z-S.

Thanks heaps for your help,
Rob.
