HANTEK DSO4202S
By all indications, NAND died
I'm trying to flash a bricked oscilloscope using dsoflash.
Can't find DFU mode button to start USB flashing.
Who has a positive experience with my model share PLEASE.

Dear Sir
What's wrong with the machine?

The oscilloscope does not start.
I wrote to support, they wrote to me to return the device to them by POST for repair.
I asked for firmware and recovery instructions.
Support refused me

Yes, it is on boot stage.
Only blank screen.
And the backlight flickers

Is my problem unsolvable?
