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.

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

Dear Sir，
I would like to ask if the machine cannot be turned on and is stuck on the boot screen. If this is the problem, please provide the serial number of the machine.

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