Sniffing the Rigol's internal I2C bus

Firmware 01.09 will not let you enter the codes for upgrade options.
Have you tried downgrading to 01.08 which does work on mine - place the firmware on a usb stick which is known to work on your unit (try saving a screen shot to it to make sure it works with your dsa815),  plug the stick in, switch on the unit and hold down the preset button when booting up.
If it does boot into 01.08 then hopefully you can enter the options - bear in mind it might not let you downgrade with the latest boot option, but worth a try.

Update File Error!

When trying to boot from usb key including 00.01.08 firmware  :-//

(i have try booting on usb key with 0.01.09 firmware, and flashing firmware works fine. So i presume Rigol do not allow flashing with previous firmware version.  |O )

Just bought one 2072A.
Used the D2072A Unlocking Guide
Installed firmware DS2000(DSP)update_00.02.01.00.03 (license keys dump).
The web based keygen does NOT work (even if I enter priv key).
Rigup 0.4 keys work.
However ! Unlocking over SCPI did not work - had to enter keys manually directly on the scope. (just got timeout error)
However ! Guide has wrong unlock "id" - "NS8H - All Options + 300Mhz" YOU SHOULD USE NS8N
I installed all options
Installed 200MHz
And then finnaly figured (found) the NS8N
After unlocking installed firmware DS2000-03_00_01_03

Some say 5 minutes.. well I spent at least 3 hours.. (but it was worth it)

Just a note. I also bought at 815-TG.. and just used the web based keygen.. unlocked all options.

For that unlock I used 1.03C with priv key (presinstalled) 80444DFECE903E

Entered generated keys directly on the spec ana.

CAPITAL LETTERS AND NO SPACES OR DASHES.

AAAB - Tracking Generator
(0001) DSA800-TG

AAAC - Advnced Measurement Kit
(0002) DSA800-AMK

AAAD - 10Hz RBW
(0003) Is it 10Hz RBW

AAAE - EMI/Quasi Peak
(0004) DSA800-EMI

AAAF - VSWR
(0005) DSA800-VSWR
