Re: GH4 Service Mode Lock

Having serviced them, I can tell you the info you posted is not totally correct. When the initial settings are erased, once "reset" the camera reverts to a set of initial parameters, loaded to allow the technician to complete the recaliberation. Without any such parameters loaded, it would be the equivalent of loosing the BIOS on your PC. This same procedure happens automatically when the main PCB is replaced. Usually before the technician begins any repair he enter the Service mode and download the ROM DATA. Following the repair, it's loaded back in, or the camera is recaliberated.
