Hacking the HDO1k/HDO4k Rigol 12 bit scope
the Chris:
Welcome ixtern.
The error message you got should only occur if you have more than one adb device connected. It could have been your mobile or the scope itself if attached via USB alongside the ethernet connection. If you don't have any adb device connected via USB, opening the connection via "adb connect IP:55555" should establish the connection while registering it, making the only choice of communication for the computer you are running the adb on.
Best wishes,
Christian

Hmmm... this should have been an edit, not a self-quote, to add a paragraph. Edited for clarity, I wanted to add:
Anyway, specifying the specific device in each command is obviously possible as well in case there is a second device which you do not want to remove for reasons.

I think you are right. Perhaps I had scope connected by USB too.
At the time of upgrade I executed command:
/adb devices
List of devices attached
192.168.1.22:55555 device
emulator-5562 offline

Hi all. Have done a lot of reading but still not building a full picture of the state of unlocking the HDO4k series.
If I purchased a new 4204, would I be able to unlock memory, decoders and bandwidth?
If so, is there a brief write up somewhere? I'm not seeing it...
Also while I'm here. Do the SE active probes work with HDO series?
Ta!

I'll chime in as a former DHO1000 owner. The firmware is identical for the two scope series (but with different options supported/enabled), so "upgradability" should be the same.
At the moment, it is possible to generate unlock keys to enable bandwidth, memory and -- to the extent Rigol offers them officially -- decoder upgrades. However, for the smaller siblings (DHO800 and 900) Rigol has just released new firmware which uses a different security scheme, possibly via a proper public/private key implementation. So far, no key generator for this new scheme has been published.
There is an alternate hacking approach for the DHO800, which makes it think it's a DHO900; but that does not apply to the DHO4000, which is already the top-of-the-line model. So if Rigol decide to switch to the new security scheme in an upcoming firmware release, the DHO4000 would no longer be hackable (unless someone breaks the new scheme and makes this public).
Regarding probes, I assume "SE" refers to Rigol's single-ended active probes, rather than to a particular series named "SE"? The scope's datasheet lists all supported probes: https://www.batronix.com/files/Rigol/Oszilloskope/DHO4000/DHO4000_DataSheet_en.pdf, pages 5 ff.
