Was it Rigol? :-DD

Rigol has two lines of 'scopes. Some that are really, really easy to hack and others that are really difficult.
It seems obvious to me that Rigol unofficially "allows" the hacking. They'd all be in the "really difficult" category otherwise.
It's not as if they don't know it happens.

This.
However, the 100MHz option is not unlocked with the newest firmware, it's the one that matters me the most.
@ebastler if it works like asymmetric encryption, then it is asymmetric encryption independent on how good the implementation is. I read (some of) riglol's source code and the basis is that they have a private key, don't know who got the key (and/or wrote the program), and how they did they obtain the key, cracking the encryption scheme, brute-forcing or social engineering.

AFAIK EEVBlog user cybernet is the one that threw some stones at the Rigol firmware, then poked it with a stick and it soon became obvious, that the encryption must have been implemented by an unpaid intern - or something along that line.

Bicurico:
Once a keygen is released for a test equipment, it becomes very difficult for the manufacturer to close the door.
Unless the number of sold devices is reduced, so that the new FW can contain the serials and respective options of all devices, it is basically impossible to change the license mechanism without having all legitimate customers entering new keys.
The Riglol hack produces serials that are 100% identical to the official ones. How should a new FW invalidate illegitimatly activated options?
It is perfectly safe to install new DS1054Z FW releases and meanwhile it has been made public how to revert to older FW by use of a magic USB disk.
Regarding the other questions: I am not at home and I have not tested anything.

Easy: The key has a lot of digits. The first firmware could only check the first 10 digits are correct. The next firmware checks 12 digits. etc. Spread the firmware updates out over several years. and you create a constant cycle of disappearing options and new keygens.
It won't fix the problem because the new keygens will eventually appear, but it answers your question.
