Or does that SCPI hack not work on all Rigol models? Which models work? Which models don't work?
Does it still work in the newer firmware versions?

As far as I know, the only option right now with the DSA815 is pulling the write protect pin on the FRAM chip high to extend the trials indefinitely. The newer bootloader disallows installation of older firmware, and nobody has cracked the newer firmware yet.

It varies by product.   The DS1000Z/MSO1000Z don't support the SCPI reads for example.   and while the DS1000Z do work with gen software the MSO you have to open to dump the memory to get the gen to work.   So its a 'it depends' on the  product as to why some are using JTAG.  plus if you want to enjoy and have some fun there's nothing like opening your own up.
BloodyCactus:
the 1032Z AWG does not support dumping the memory over SCPI read command either.

On the website of the tool Rigol Bildschirmkopie LAN/USB it says MSO1104Z:
http://peter.dreisiebner.at/rigol-bildschirmkopie-lan/#screenshot

Benutzer konnten das Programm mit folgenden Geräten verwenden:

    DSA815 - LAN/USB
    DSA1030A - LAN/?
    DS1074Z-S - LAN/USB
    DS1104Z-S - LAN/USB
    DS2202 - LAN/USB
    DS4054 - LAN/?
    MSO1104Z - ?/USB
    MSO2072A - LAN/USB
    MSO2302A - LAN/USB
    MSO4024 - LAN/?
    DM3068 - -/USB


Does that mean that for MSO1104Z in particular it works and not for MSO1074Z?
Or does it mean that it works for all MSO1000 series, but only via USB and not via LAN?

shrek:
Has anyone tried to hack the DP832's ANALOG board? Any luck with JTAG and full memory dump of the controller?
