--- Quote from: Sparky on October 31, 2014, 07:19:13 am ---To my knowledge we do not know why some units fail to be upgraded to 300 MHz and I decided to investigate. I corresponded with a few MSO2072A owners here to see what may cause the 300 MHz option to not install by comparing hardware/software versions and the "Hardware Version" resistors. So far I have found identical hardware/software versions, and resistor settings, which in one case the 300 MHz option can be installed, and in others it can't. Since the 300 MHz option works for practically everyone, I think we can be confident the algorithm is correct. I wonder if the scope does a separate check of the key against some other parameter (either resistor setting, or EEPROM values) to see if the key should be accepted. >> If anyone has ideas about this, please tell! --- End quote --- Following up on my own post, I compared high-res images from MSO2072A that could be updated to 300MHz and also the one I currently have which only allows the 200 MHz option, and I cannot find any differences (e.g. hardware resistor settings). So I wonder if the license key check withing the firmware is making additional comparisons to validate keys, perhaps against data stored in EEPROM. Anyone have thoughts on this? |

Hello all! I just received a new MSO1074-S. Someone know when the new code for the keygen will be avalaible? The old keygen does not work with firmware 00.04.01.SP2. Someone can put the new key table for these models to update the keyen? Thank You All! Manuel |

I read a few pages back that someone had managed to make a new version of the keygen work on the MSO, it required a different key if I remember correctly. |

Hello EV1Te and Thank You for you response. :-+ User rmd79 found the private key for MSO100Z. But it is not enough, We need the OPTIONS CODE which found user SMPT14a. I tried these private key and CODES in the riglol software but not working. The user sptm14a also found the way to make it working but yet He not detail the modifications to the algorithm He make. I sent a PM to him, but has not yet answered. I will study the source code of the riglol tool to see if I can find something... As you see there are some info nested inside the thread, HI HI.. |O Regards Manuel |

But according to his profile he hasn't been on the forum since October 27: https://www.eevblog.com/forum/profile/?u=99473 |
