[updated post after success]
Hi,
I got today a new DS2072A, HW version 2.3 and SW version 00.03.05.SP3.
After just 4h and lots of frustration I finally have all options and Model 2302A on the screen.
I tried to unlock the 300MHz bandwith and all options by using the ds2000a-upgrade-utility but flashing the firmware failed every time. I had the file on a FAT32 stick and the scope in the upgrade mode (Single LED on) but almost instant after putting the stick into the front port all LED's in the "vertical" section, all in the "trigger" section and the multi knob and Run/Stop illuminated. I left the scope like this for >1h, no change. Rebooting as described with the "F6" button pushed down didn't do anything. I tried several FAT32 sticks and could never get the modified firmware onto the scope.
Then I tried the memory dump vial LAN using "Rigol Bildschirmkopie" and this was the first success. I had a 32mb file.
But retrieving the keys with the rigup tool was not easy. I assumed that the latest version must be best....wrong. 0.4.2 didn't do anything on my PC. After lots of try and error I found the "rigup02" folder on "
http://www.gotroot.ca/rigol/" and this tool (rigup-0.1)worked.
I got 4 Keys (NSEH, NSER, NSEQ and NS8H).
The NS8H changed my DS2072A into a DS2302A with all options activated.
Thanks to everyone who made this hack possible for dummy users like myself.
Best Regards,
