X-T4 dead after 1.23 firmware update

[pytlak]

Hi

my camera is dead after the firmware update performed via mobile application. Update was not interrupted, ended properly (At least I think there was no problem) and then camera went black. It cannot be turned on, no new battery replacement  helps. it is not possible to start camera even for the new firmware update / return back to one of previous versions. Till today no problems with camera at all. Is there any possibility to connect camera to PC and reset or install firmware? Any ideas please?

Don't do firmware via the app

 

Always download onto a blank memory card only and install that way.
