Sniffing the Rigol's internal I2C bus
Macbeth:
Can you not flash an old firmware then activate the keys on that before upgrading back to the latest?

I didn't think downgrading was possible.

If your dump is 16Kb it's too small.
a 0x3FFFFFF is 67108863 bytes
The openocd command is
dump_image mso1074zs.bin 0x40000000 0x3FFFFFF
Thats start at address 0x40000000 and dump 0x3FFFFFF bytes so if you have a 16Kb dump it's not going to work
If that is a typo and even if you meant Mb it's still too small to be sure you got everything.
If you do have a 64MB dump please ignore this, otherwise if you truly have a 16Kb dump, please try it again and be sure you get the full 64Mb+ dump
What boot loader do you have? has it been upgraded to a newer boot?
if not, try downgrading as MacBeth stated.
Downgrading isnt' possible with the DSA815 I've not heard anyone say the MS01074 wasn't down gradeable.

The memdump was 64MB. I never said anything about a 16Kb dump, plus I have isolated where the keys are in the memdump, it is in a different location than what rigup 0.41 is scanning for with the new firmware. (See the top of this page)
According to this thread https://www.eevblog.com/forum/testgear/rigol-ds1000z-series-firmware-downgrade-*is*-possible-and-here-is-how/ downgrading only works on a very old bootloader version. My Boot version is 0.0.1.3. Only versions 0.0.0.11 and 0.0.0.13 allowed downgrading it would seem.
*EDIT* Okay. I tried the downgrade process doing the press help 3 times method and it just beeped and blinked at me until I turned the unit off. Trying to downgrade the traditional way also ended in failure.

It was a previous firmware version, more than a year ago.
