Sniffing the Rigol's internal I2C bus

<< < (467/899) > >>

I had mistakenly thought the option code and serial number were being decrypted from the license code using the public key. Now I see that the algorithm verifies that the signature pairs embedded in the license code are valid before accepting the decoded license.  Was confusing public-private encryption with signature validation.

DP832 Power Supply with Firmware 08:

Please, has anyone been able to successfully activate the DP832 Options by downgrading to Firmware 06, installing the keys from the Riglol 1.03c Keygen, and then upgrading back to FW 08?

I have seen others ask questions about this, but I haven't seen any replies.

Or, is there a version of a Keygen that will work with a DP832 with Firmware 08?

Hi,

I've got the same problem. 06 works no problem at all, when I upgrade to 08 all options are gone. When I downgrade back to 06 everything is official again.
BTW I am using Riglol 1.03c.

This seems very odd. Does this mean that people who actually bought options legally from Rigol for the DP832 can't use the newest firmware?

I have 1.03c Keygen also, sorry but I left off the 3 from the Keygen number above.  Thank you for your reply.  Now I wonder what alternatives we can find without an updated Keygen for FW 08.
