Nothing is working after updating.

[Ryder]

Hello!
English is not my current language, sorry if was bad.

I got a Recalbox recently, so I'm new to all that.
I got the Recalbox with version 4.0.1, so I update it to 4.0.2.
The system restarted and warned that a new update was ready.
But the usb control did not respond to my commands, so I figured I should use a USB keyboard, since the control settings were restarted because of the update.
By the time it happened (a week ago or so) I did not have a USB keyboard, so I decided to buy one, and that's what I did.
Now when I turn on the system, I get stuck on the initial screen of the recalbox, no sound and the keyboard is not working, just like the control.
What should I do?

Any help is appreciated.
Thank you!
