Can you not use riglol to generate a key?

You probably wanted to say rigup, the memory dump scanner, of course I've tried to use it, after painfully dumping the memory and... "No keys found"  |O
I wasn't collecting it a good point, or the SP3 version of the software closed this loop or is a special East European version, with even more difficult ways to upgrade it  >:D.
I will try to collect another dump, but I'm pissed off that I just nicely closed the scope and wanted to open it again only when the silent fan arrives, but now I have to force myself to open it again(still hi fever and adverse reactions of this bloody strong antibiotics :( ) and collect a new memory dump, I don't know how long I survive and don't want to let the job unfinished.

I had a faint hope that one of the original researches wold look into the dump, but most likely the dump is invalid, if the second dump fails, I'll post in original mega-thread.

 Cheers,

I've had a bit of luck  (please see edit above) and thanks to all for the good words and advice, it really helped my shaken spirit with all this sickness.

Cheers,

Sorry for reviving this thread, but we're having a little "Black Screen Of Death" situation here - scope worked, removed thumb drive, turned off, turned on again, now it only produces a buzzing sound (~20 Hz). It experienced a very light knock on the backside of the enclosure while picking it up from the place where it stood which really shouldn't have caused any issues and may be coincidental. Very strange - Here are the SMPS open-circuit voltages:

Blue: 15.28 (17.5 V)
Grey: -15.16 (-17.5 V)
White: 8.84 (9.0 V)
Yellow: 6.02 (7.5 V)
Green: -5.98 (-7.5 V)
Red: 4.42 (5.0 V)
Brown: -0.03 (OPTO)
Orange: 0 (GND)


current suspicion is that the SMPS PCB flexed and a voltage divider resistor broke - having the heaviest components in the center and only being mounted on the short sides would be asking for flexural damage.

component side image is from Dave's teardown (EEVblog #674),
solder side image is from what we're looking at here, while the top is identical (also V01.01_20130504)


Has anyone seen this behavior so far? It really feels like a very odd failure mode.
