Yes, looks like the NAND is fixed and at least the Windows image is booting cleanly but the oscilloscope application is not running. Just to be sure, did you remove the USB drive? This behaviour looks like the startup override could still be active.
I did put both cab files (2.35 and 2.65) on the same flash drive, and i just tried "48#\Secure\infiniiVision\infiniivisionLauncher.exe", however the 'go' command takes me to the 2.65 spasl screen where with nothing else happening, so I'm not sure what is happening there.
The first time round (as shown in the youtube link + previously attached log) was transfer made, go command executed, then inside oscilloscope OS, called utility to update to 2.65, then the rest is logged as I showed you. I didn't remove the USB stick, should I have? Now I come to think of it, that override with 'true' is still in the stick, let me try removing it.. aaaand it's fixed.
I could kiss you.. (and titiris and all the others who made really helpful documentation). There's no way I could have caught this all myself. Thank you SO much.
Now to figure out how to retrieve the licence that was purchased years ago for the wave generator. Was it quite easy to hack/unlock this scope ? Edit: wave generator still works. Hooray
