Hello again DC1MC,

I really hope you can use these files. I am quit certain that they come from an original Voltcraft MSO-5062B. After all the trouble I had with my modified / converted DSO / MSO this thing was ordered from Conrad. That was a bit of a disappointment. The thing had the same problems as my modified one; so Conrad took it back and refunded me. But I did make a backup of it, you know, for just in case..!.

The MSO firmware has a strange bug, the digital and analog traces on the screen are not always from the same trigger event, that was my main issue to send it back.
Also it doesn't do any protocol decoding so.. my remaining modified Voltcraft ended in a box in storage when a better MSO came on my bench (HAMEG HMO3054).

About restoring the firmware from the dump files:

I found in my old computer a pdf that describes "how to" proceed with a restore. It looks you are aware of this info as well since you mentioned the special dnw.exe program that is needed earlier in this thread. But just for fun I will attach it here.

This is nice PDF from the site, it's good to have it here as well, because the sites are volatile and the post there was from 2013 or something. Thanks God that I don't have to deal daily with this POS, from what I've seen and read so far, is distilled highly concentrated Chinese crapo, as opposed to the more diluted crapo of Rigol and friends, for some strange masochistic reason it's very loved in Germany, it even has a name "Das Oszi" and is for a friend (hopefully will stay friends afterwards)  :-DD.

In any case, thanks once more,
DC1MC

Just a quick and sad (or maybe happy  >:D ) update, after restore the scope is totally dead, no u-Boot, no USB reaction, no serial output  :palm:. So most likely will need a JTAG connector and a working image to be restored, but most probably the insides will host some other project that can use the case and screen.
Or if someone needs some specific parts or the whole cadaver, please PM me (it's not free unfortunately. but also not expensive).

How did you do that?

Relatively simple :'(, the u-boot there seem to not have been the original or at least the one that the documents were referring, now I can either forget all the rest and either see if one of my J-Link clones see the NAND or it will house there a RPi or something else, because the other options seem to be parallel port LPT JTAG programmers that no one will ever make or have a machine with LPT. I barely found some Windows32 bit cadaver.
And if indeed these calibration files must be there for the device to actually operate, than anyways it would have been useless I think, (maybe it recreates them automatically or I could get them from somewhere) but until I manage to see the NAND somehow, it will collect dust like the rest of them.

Cheers,
DC1MC
