a6300 firmware update error, iso miscalibrated, aperture blocked and does not renew automatic lens focus motors.

[hugoa6300]

My camera has an update error, it does not recognize the motorized focus of the lenses, the iso is out of calibration (I mean, I need high iso numbers for the image to be seen) and it does not let me change the aperture of the diaphragm, I suspect it is the plate but what could it be? It is an a6300 and it is in the latest firmware version, when I try to reinstall the firmware the sony software tells me that the update was blocked because it is in the latest version
