Does that mean I can't upgrade it with the JTAG method anymore?

I've made several posts about not being able to unlock the later versions of the MSO1074Z-S. Riglol (gotroot.ca) hasn't been updated to reflect this; nor has there been any discussion aside from me making a fuss.
I suspect something has changed around version 04.03. Even the modified serial generator for the MSO1000 series on Riglol fails to find keys if you don't modify the offset to the new location where the keys are stored. Even after making the modification and generating the keys. I get a verification fail on the key signature.

As it stands, it will take several more new owners of the MSO1000 series before we will begin to see any action. It's unfortunate.

Just bought a MSO1074Z-S, and unfortunately it came with firmware 4.03.SP2.  Board revision is 6.1.2, if that makes any difference.  Obviously, me asking when riglol/rigup will support the new firmware is of no use to anybody, but is there anything I can do that would be helpful at this point?  I haven't managed to grab the memory dump yet, but I do have the tools to do so, and I'll try to get that done this weekend.

What about unlocking the options for the MSO1104Z model? Is there any developments???

Is any of these devices suitable to do the memory dump of my Rigol MSO1104Z

Compatible JTAG adapters are listed in message #2413 in this thread or do a search on the main page for "memory dump jtag" ...  :-//
Have a look for the descriptions of the mentioned debuggers and do a comparison.
I dumped the mem in the past with this one: Olimex ARM-USB-OCD-H

Have fun!

Cheers
