Patch for disable: "Open lens cover" ??

I`ve a K810i
Replaced the front and back.
After replacing tje camera function keeps saying: "Open lens cover" even when it was already open or without the back placed.

Couse: a broken leaver at the microswitch right/under the camera, so when you open the lens cover, the switch will not switch on the camera.
Now i`ve read something about a patch that solves the message "Open lens cover" ?
And if it`s there , does it really solve the problem... can the camera be used trough the menu only after patching ?

thx

try to change the switch, you may try with the mobile mechanic, they would have spares
