DSO2D10 bugs, freeze and so on

Nya

Got new DSO2D10, damn Hantek!

1) 1kHz real signal it shows like 400-500Hz signal with memory depth = 4k, 40k, 400k! And it show frequency of signal like 400-500Hz! What the hell?!
With 4M and 8M memory depth it shown like 1kHz.

Firmware was from 2020,  I updated to latest from website:

Software 0.0.1.1.0 (2021416.00)
Hardware ... .001
Firmware a015

Why last software starts with "0" ?
Why firmware version is "a015", not "3000" or something?

2) I tested it, In menu I've changed:
ACQUIRE > Memory Depth > 4k to 40k.
After that signal line disappeared.
If I select memory 400k and more, DSO is froze.
If restart, there is no signal line and many buttons does not works, and I can't change memory back to 4k. If I try to select 4k, DSO is freezing.
I can't reset it to default - buttons does not work.
Update menu button works and I can upload firmware to the same version 20211416.
After that DSO works, but If I will select 40k memory and more, problem will appear again.

What should I do?

I did it.
Software changed to 0714.
Firmware did not changed, A015.
It did not solved my problem.

I found why I catch freezes. Because you idiots can't test your oscilloscopes just by clicking buttons. You have many bugs in menu and menu conflict with real settings.

Hint for hantek's housewifes: switch Decode mode to Disp: Monitor, then press Decode button to hide Monitor data table, and then try to change Memory depth to >4k. Good luck, idiots.

So, where my "3202 firmware" is?
