Just updated my latitude 5300 bios via dell command update to 1.19.0 and after that, usb-c port is dead, it doesn't recognize anything connected and, what is more important, I can't charge my laptop anymore (tried dell and baseus usb-c chargers, both worked before and both don't work now). Old charging port works ok, I managed to get an old charger and it is doing its job right now. Is there a way to downgrade bios or maybe there is something more I need to install to make it work?
