BUT, we earthling engineers should also have in mind that we are bound by the economics of the world we live in. Or else, we can say that they could do all that doesn't break the laws of physics. Changing the pubkey in their flagship product, as has been done in the past with others, HAS TO involve migrating all the licenses that are currently working in the equipment. As such, once that FW upgrade is installed all "official" and "unofficial" licenses will be happily upgraded (because ANY upgrade program will have no way to differentiate both types of licenses) and what once was a "official/virtual unofficial" situation becomes an "all official" situation. So, everyone stays licensed and only the new guys must redo riglol with a new private key. |

They might have a database of all the legal keys that they could include in the firmware update to keep them working, sure. OTOH no company is that competent and it's probably too big to fit in memory anyway. Plus: We all know that hacking is part of their marketing strategy. They still made money on all those hacked 'scopes and they've sold millions of them because of it. |

--- Quote from: whotopia on June 18, 2016, 08:44:59 pm ---Can someone help me out to restore the serial number of a DS2072A ? I tried to do some of the hacks in the distant past and this lead me to a unit with serial number DS2A0000000001. The MAC address on the LAN interface is also screwed up. It's 46:46:46:46:46:46. I assume this must be uniquely generated from the serial number somehow. The device is currently at firmware DS2000(DSP)Update_00.03.04.01.00 I think if I could get hold of a memory dump from someone with a working unit (and what their serial number is) I could write back correct values into the scope with my own number. Thanks! --- End quote --- I don't know if this is still relevant, but I had the same issue and was struggling with it since 2013-2014. Finally the solution was found. Read this post: https://www.eevblog.com/forum/testgear/sniffing-the-rigol_s-internal-i2c-bus/msg369122/#msg369122 And follow the steps exactly as described. This is very important since when you flash the patched firmware, the serial is stored in RAM only. And you HAVE to uninstall all options in order to write your serial into the flash. Hope that this will help people with the same problem. And kudos to people who made this solution available. |
