Hello, I'm looking for a miracle solution

to unbrick my SDG6022,
It happen while reading a waveform from the generator to the Easy Wave software. The generator appeared non responsive so I cycled the power to the generator. :. At power up the Siglent logo blinks, followed by faint clicking, then stops on the logo screen.
Repeated power cycling does not fix the problem, because the FW update is accessible through the user interface the FW cannot be downloaded, the front panel buttons are unresponsive.
Disconnecting the USB from the host did not fix the problem
This sucks, the arb, is new to me and has seen very little usage, your help is appreciated
