Sniffing the Rigol's internal I2C bus
elebot:
If both the HW and firmware of the DP832A and DP832 are basically the same, what actually distinguishes the two models?
Serial number range? Or some license key? Is it obvious from the firmware disassembly?
I am curious how feasible would it be to do the full conversion into DP832A as I would love seeing on my DP832 multicolor classic mode and with normal font (not the 7 segment display simulation).

As the latest DS / MSO 2072 having SW 3.0 SP1 and HW 2.2 refuses patched firmware gel file ver 2, what about modifying the gel file to pretend it is ver 3 ?
Is there something like header / data structure in the first block of the gel file which defines version ?
I am asking because if I open any (2.0 or 3.0) gel file in hex editor, there is a version string at the beginning.

I can also confirm:

MSO1104Z-S, serial no. starting with "DS1ZD" -> doesn't work.
Maybe they have changed the algorithm or at least the private key and provided downward compatibility for the first DS1000Z scopes with "DS1ZB" serials.

I tried: http://riglol.3owl.com/ with options DSFR, MSAJ, DSAE on MSO1074Z-S, serial no. starting with "DS1ZD" -> doesn't work. I'd love it if anyone else had any thoughts. Could the fact that the scope still has the trial options enabled have an impact?

There'll be more to it than that. Version 2.x will know nothing about the MSO features, could end up bricking the scope.

Hello all,
I'm plainning to buy a MSO4000 series wand i would want to know if the hack could work on it (in order to choose the 100 MHz and hope hack it to have more bandwidth)
is it possible ? and how ?
