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...

Hey Guys,
Just curious are there any more updates from the people who are patching the .so files (and potentially apk files) to get the 1074 to have the 400-800 mhz passive bandwidth on a single channel, as well as the increased available memory, and 50ohms impedance front end support, as well as some of the extra feature options available for some of the 4000 scopes. I know that some people had most of this working, and I was really hoping there would be some more updates about which so files need patching. I think most of the details were already written but it would be great if anyone who has done it could detail all the steps available (I'm assuming no one wants to put up the modified files at least, so a step by step by anyone willing would be the next best thing :))

You won't get 800MHz, for that you need dual ADC's of the DHO4000. 1 ADC = 2Gs/s, 2 ADC = 4Gs/s total shared sample rate.
We already have the ~400MHz BW, at least I do when testing.

But yes, bounty is still open for your request.

From a bandwith perspective, we can obtain 800 MHz (at least this show my measurements) , but you can't use for measurement as the values are doubled.

The DHO800/900 family has recently changed its option licensing AES key and format. I've rewritten the option generator and
since the libscope-auklet.so library is shared between the 800/900/1000/4000 series I believe the following applies to this family of scopes too:
