Is the Rigol MSO1074Z hackable?

Thank you for the help, it worked!

All newbies like me, you must delete all the characters in the SN entry box before entering your SN. I deleted up to the 'D', but that apparently does not work.

As it currently stands, you will need an appropriate JTAG debugger.

Smgvbest has an excellent how-to here https://www.eevblog.com/forum/testgear/sniffing-the-rigol's-internal-i2c-bus/msg569236/#msg569236 , far better than my attempt a few posts earlier which had been written some weeks after doing it (for reference here https://www.eevblog.com/forum/testgear/sniffing-the-rigol's-internal-i2c-bus/msg566312/#msg566312 )

Smgvbest says that the debugger she used is no longer made. I used an Olimex ARM-USB-OCD-H which is still available.

Looks like the link you posted isn't quite right any more.  The apostrophe in "rigol's" breaks things.  Here is the correct link:
