--- Quote from: loaderr on November 21, 2016, 09:00:58 am ---Hi all, I'm trying to unlock MSO1074Z with expired trial license with no luck so far. A while ago quertymodo had a theory that keys are get locked some time after logo disappears which sounds credible to me. If someone still has a correct dump could you please try to compare relevant info from it (136 bytes starting at "01 00 84 00 10 00") with unsuccessful dump or just some other dump made later to prove the theory? Thanks. --- End quote --- What you mean with "unsuccessful dump"? A dump that generated keys but which keys didn't worked? I can provide such dump but I cannot provide a successful where keys has been generated and worked! |

That's exactly what I meant! Dump that generates license which doesn't pass validation. If we compare it with one that generate correct license than we will know if problem is in scrambled keys or something else. But we need 2 from the same device. I have the same problem - I have "bad" one but no good one. We need to wait for guy who where able to unlock their devices. |

Has anyone tried messing around with the new dg1022z function generator yet to see if it's possible to unlock other options? It does have the option to purchase increased memory depth, which leads me to believe it's made similarly to their other products with frequency limited by software. I would be very interested if 60MHz could be unlocked, as the 25MHz model sells for $360 and the 60MHz sells for $860. |

I can only dump memory and generate "bad keys"! |

Ok, I just got a new licence key (trial) for the scope. Should I do anything before/after/between applying the key and making a new dump file of my scope's memory? Someone said to try to compare the memory dumps of someone with working and non-working licence keys! I have now the possibility of having the options with Trial time again, make a new dump and try to generate new keys! |
