Sniffing the Rigol's internal I2C bus

Dolence:
Mine come with packages unlocked from factory(no time restriction). Is there any benefit from this? Like upgrade from 70mhz to 100mhz?
xyybob:
I have worked with members of this site to try to unlock the DS1074Zplus but not been able to do it. Looks like it can't be done!
S. Petrukhin:
Hold on... In one of the topics here, a person asked for the source codes of Rigol scope based on the GPL license...  :)

Sure, it can. You have to use rigup, not riglol.

I'm in a similar boat to xyybob. I have a DS1104Z Plus, I've done the memory dump using konnor's firmware, I've scanned the bin file and generated a keys.txt, but all of the license codes I generate say they are invalid. Someone up above said there's something you need to change in rigup prior to compiling, but I must be missing where to do that. I didn't compile rigup anyway, I used http://gotroot.ca/rigol/rigup-0.4-mso1000z-with-bins.zip which was the which was the version most recently posted on the site.

XMAS 2020 GIFT to the whole RIGUP community    :D

There is a bug in the rigup source code that makes certain scopes to not accept the licenses generated by any rigup version.

(I know this is pretty old stuff but the error is there... has always been.)

The option licenses are based on a hash of a string that has this format:  SERIAL_NUM + OPTION_CODE + XXTEA_KEY

The problem is with the XXTEA_KEY. Certain XXTEA keys contain NULL bytes. Current rigup source code always concatenates the 16 bytes of the XXTEA but that is wrong!

All 00s should be removed from the hash buffer when adding the XXTEA key (and the hash buffer size adjusted accordingly).

All those who have problems licensing, MS1000Z+, etc. please check your XXTEA keys (to see if you have 00s) and you'll be able to verify this.

Now it's up to rigup hosts to correct the available software versions.
