I have an MSO2072A with firmware version 00.03.00 SP1 and hardware version 2.2.
I tried the USB port but it wouldn't work so I tried the LAN connection and that did the trick. :)
When sending the commands using RigolBildschirmkopie.exe it said "There was an error when sending the SCPI command." but it worked anyway.
Looking at the installed options, it says I have both the 200MHz and the 300MHz options installed, along with all of the rest of the options.

I can also confirm that this works great. Only tried LAN using "RigolBildschirmkopie", which I guess means RigolScreenshot? :P
Brand new DS2072A from tequipment.
It came with:
Software version 00.03.01.00.04
Hardware version 1.0.2.0.2
FPGA Version:
SPU: 04.00.09
WPU: 01.01.03
CCU: 12.29.00
MCU: 00.06
Shows manufacturer date of Aug 4th, 2014 (I guess these have been in stock for a while?).

don't see discussion of that in the thread (I didn't read all 262 posts tho) and gotroot only shows non BW related option enablement.
will DSH9 "all options" also bump bandwidth? to what?

Cannot be done by option, you'll have to flash special adapted firmware for this purpose. Search for the link for the Rigol files and then for 2.01 from Mr. Krabs. That'll release 500MHz bandwidth.

That (too) has changed, some 6 months ago.
See this post and the .pdf attached to it.

Thx guy! Did not follow the thread for a while.
Any idea how to unlock latest Ultra Power Analyzer?
Asks me for a key with 4 fields but generating it the same way as described shows that it does not work.
Seems that there's missing a character in the 1st and 3rd field.

Not sure I understand what you mean.
Is it missing a character in the 1st and 3rd field of the generated code or what?
Looking at the .pdf I'd try FAK9 which would be 500MHz, Power Analzer and all decoder options but no the MA option as I don't know what that is. Punching that into Riglol 1.03d gives me key containing 4 groups of 7 characters each. I didn't try it my scope though.
Apparently they've added support for 1553 bus decoding and triggering in the latest version, that's an option which isn't covered in the .pdf
