Sniffing the Rigol's internal I2C bus

Summary for the 2xxxA version:

Variant a (patched firmware):

- get the patched firmware that enables to use old keys
- load it onto the scope
- use the old key

Variant b:

- get the patched firmware that reads out the keys from the scope
- load it onto the scope
- use SCPI to read out the keys
- load official firmware on the scope
- use new keygen with the keys extracted via SCPI


ps: the guy who wrote the keygen said "no pain, no gain". The easier this is, the more effort will be taken from rigol to make unlocker's life harder..

MrAureliusR:
That's true. Thanks for the summary though, that's all I needed to understand!

EDIT: Is there a re-host for the official firmware somewhere? I thought I saw a link in the thread but now I can't find it... the Rigol downloads are horrifically slow. I was trying to download the Ultra Sigma software and then realized Batronix not only hosts it but they have a newer version than on the Rigol website!!

you can use telnet on port 5555 to talk SCPI, no need for ultra sigma..

Actually, I DID READ THE THREAD, it's really annoying that you're trying to 'prove' that I didn't. I know I could use telnet, but I figured I'd end up downloading the Rigol software anyway, and so why not just use it?

If that fails I'll use realterm or PuTTY and use telnet.

Like, why would you assume that because I'm downloading Ultra Sigma I didn't read the thread? They actually mention a couple posts apart both methods.

I realised that this was unqualified right after posting, so I've already edited my post.

Just for the records, this was referring to the firmware file, not telnet.
