Hi Amy.

Received some days ago a brand new 2d42. it was not with the last fw version so I decided to update it using DfuSe Demo package and HantekHTX2019110801.dfu.

I Uploaded the dfu file under "Upload Action" instead of using the "Upgrade" section. I noticed that as at the of the loading phase the scope did not reboot.
So I retried using the right section of DfuSe (Upgrade), but right after pressing the Upgrade button, it hangs in "Erasing Phase". After a bunch of minutes (more than 15) it was always there.

I had to detach it from the PC, but now it won't power-on any more.
I have found the software and instructions you provided, so I will try to follow them and make the scope revive.I will give you a feedback on that.

Just a couple of questions:- about USB-to-Serial adapter, should it be a 5V or a 3.3V ?
- do I have to connect power through the USB-C cable while connecting the USB-to-serial cable ?

Thank you in advance.
