Would a customer expect all his paid-for options to vanish if he did a firmware update? Of course not. Riglol-generated keys are no different from "official" ones. |
| ebastler:
Ok, agree. The process is a bit more involved for the MSOs and the -Plus version, but the result is the same. |

If I upgrade the firmware to the most recent, will I lose my hacks? --- End quote --- No, because you didn't "hack" anything. All you did was enter a key - exactly the same as a paying customer would do. --- End quote --- Are you really going to get that bent out of shape over semantics? Fine. I utilized an altered firmware to allow me to dump the contents of my scope's memory and then used a community-created piece of software to generate license keys so that I could unlock, without paying, features available for my MSO1074Z-S. Isn't it just easier to say 'hacked'? The precision of the term may be lacking, but the implication is certainly there. Loosen your necktie, mate; nobody's grading you on this. |

Loosen your necktie, mate; nobody's grading you on this. --- End quote --- Fungus' comment was not about your choice of words, but about the underlying mechanism to enable the additional scope features. And his comment was a pertinent answer to your original question whether your new features would survive a firmware udate: You had to jump through a few hoops to get information from the scope and generate keys. But in the end, you generated the same keys which Rigol would have generated for you if you had bought these features. The scope accepts them since they look correct to its internal checking algorithm -- just as correct as the Rigol-generated keys. So any future firmware will need to accept these keys too. So yes, please relax and loosen your necktie. |

From what I understand, the license codes generated via the 'hacked' method are exactly the same digit-by-digit with what someone would get officially for the same option on the same serial number device. So, eventually they have to survive any FW upgrade. (loose neckties everywhere..) |
