[hitchhooker]

Hey, Ive got now half a year useless 4k cam cause it got bricked and doesnt let me perform firmware update, is there a way to force it on it?

rename firmware.bin -> firmware_force.bin and start camera.

Thanks a lot man, seems to be working. Flashing older or newer firmware didnt seem to solve the issue though, still cant enter settings or camera videos. Anybody having similar issue with the camera?

It seems that the lcd screen is somehow broken.
The options are either to put wifi on and use the camera via the application or then buy a new lcd screen

Here founds instructions how to put the wifi on without lcd screen:

New lcd displays are found in eBay:
