Iupdated my DSO2D15 with the firmware dated 2021-04-20. This appeared to complete correctly, but now it fails to boot, stuck on the Hantek boot screen.
How do I reset the device or force a reload of the firmware?
A simple method to solve it without requiring firmware reinstallation is to make a factory reset, sending the command through SCPI.
Install SCPI (Available at Hantek download page), there's a guide here
Connect the scope to the computer
Open SCPI console and write "PRIVate:FACTORY:RESET"(Keep uppercase/lowercase as that)
That way the Serial number, Model, etc, will be kept. Also avoids the USB problem after reinstalling the firmware with platform-tools.
