New Hantek DSO2X1X models?
aleph0:
I recently purchased DSO2D10 oscilloscope and it worked fine for a couple of days.
Today it began to lock up after boot and none of the buttons work.... Note that the button LEDs are all lit and no channel signal is displayed either.
I spent hours searching this forum but all of the "locks/freezes" I found were easily resolved by turning the scope OFF/ON which in my case does not help.
I have already contacted Hantek but given their record, I'm not expecting much.
I'd appreciate any help in debugging this.
Here are some pictures and a video of the problem: https://mega.nz/folder/peQBVASI#DWsjU1AMZSFBskD4B_fbeA

I hope you didn't see this thread before you made your purchase .. or see any of the negative reviews on the internet.
I honestly can't understand why anyone would buy one of these when Siglent and Rigol (and other manufacturers) with great reputations build fantastically better instruments for about the price of a Big MAc dinner and a 6-pack more.
Sorry this happened to you and I hope you discourage any you know of thinking to buy one.
All that said, you are in the right place to get help but you will need to do A LOT of work.
Good luck.

The trace of Ultra Vision technology is much difference from Hantek or others normal DSO.
If you need real digital scope but affordable so any Rigol (must have UltraVision) is my recommendation.

Check the FAQ in my signature, "Recovering" section.
First try to make a Factory reset without flashing platform-tools, so you don't lose the calibration data.

Thank you for the replies.
I found a windows box to try DavidAlfa's suggestion and here's how it went.
First I attempted a preliminary backup just to be safe. Put the scope in FEL mode, installed PhoenixSUite and zadig, confirmed that the USB device showed up properly in the device manager and ran "read.bat" from DSOFlash, but that failed. (1st image)
I then installed the Keysight IO Lib package and restarted the scope in normal mode. The software recognized the scope and I sent it the PRIVate:FACTORY:RESET command. The command "worked" in the sense that the scope immediately rebooted and the signal stats I had configured earlier, before the lock up, disappeared. Unfortunately the buttons are still all lit up and none of them work. And there's still no channel signal being drawn. (images 2 and 3).
I remember that when the scope was working, right after booting there would be some clicking noises (relay? for the AWG?) and then if memory serves me right the WAVE GEN and other lights would go OFF. Now there's no clicking and the lights stay ON. Maybe there's something wrong with the hardware?
edit: I should also add that before the factory reset the stats "count" would continuously increment as can be seen in the video in my post above, indicating that the phoenix process is probably running fine. this would be consistent with a the hardware error hypothesis where a relay that was supposed to switch never did, leaving all the lights ON and the phoenix process "waiting" for a signal that never arrives.
