Sniffing the Rigol's internal I2C bus

2twingy: check if your keys start from 0's and do they have proper length (should be 8 or 16 hexadecimal digits), if not append 0 in front of key like 0x001234. Otherwise fixed Rigup should just work for you.

Twingy:
Hello loaderr, I've attached a copy of my output from rigup, do you see anything that looks out of the ordinary?  Thanks.

Daruosha:
Since public and private keys are same across MSO-1000z models, is there anyway to calculate XXTEA and RC5 keys from serial number? I have the trial codes and looking for a solution to solve these keys from serial number and trial codes. Any suggestions?

jckz82:
I'm in the same situation as Twingy.

- MSO1074Z bought in Dec 2016
- Software V04.03.SP2
- Board 2.1.4
- JTAG header absent from board
- Ran memory dump immediately after logo disappears (did three dumps with the same results)
- Used loaderr's fixed version of rigup

Generated licenses are invalid. 

Any files or information I can upload that would help solve this?

Noize:
I had success upgrading my mso1074z-s  8)

Software version 00.04.04
Board version 6.1.1


I compiled loaderr's version of rigup with VS 2013
Used a Chinese knockoff jtag dongle firmware: J-Link ARM V8 compiled 1 Dec 2009.    Hardware version: V8.00

Turned on the oscilloscope then plugged j-link into the computer
Started J-link commander from the command line>JLink.exe -speed 100

J-Link>connect
......
Device>arm9
.......
JTAGConf> (just press enter)

J-Link>h (press enter when license screen appears)

J-Link>speed 4600

J-Link>savebin mso1074z.bin 0x40000000 0x3FFFFFF

J-Link>g

Use Loaderr's file as per usual.

I bought my scope from Rigol 3 months ago with the latest firmware installed, the jtag header was still present.

Thank you to everyone who contributed  :clap: I am now able to continue electronics thank god! Ha
