Loved the reply joke... :)

Maybe there is an intermediary upgrade that changed the FW password and your current one can't decrypt that specific.

Edit: All 5000B FWs have the "dso5000b" password.

Yes, not the sort of stable that we want.

I actually emailed that person at Hantek a few days ago. They replied that it was a hardware problem. It was not behaving like hardware so I started searching.

Last night I sent them the latest details. I wonder what I will get back :-)
Microcheap:
There is a way to restore the file system in the Hantek's scopes that eventually get corrupted, did you tried that?

A short video posted on Hantek forum shows how to do that

dave_n_s:
This scope is not going into recovery mode when pressing power on, off then on again.

I've tried quickly, about a second, two seconds and three seconds.

dave_n_s:
Hantek responded with an upgrade file that's not the one on the website and with quite a different file name format.

This is the file name: dst1kb_2.06.3_15202b_fact(140924.0).up

It would not update with FAT. It updated with FAT32. 2GB stick both times

Having said that it has powered up with no problem multiple times since I did the Default Setup trick.
