Mppt 75/15 firmware update disturbs function

Mppt 75/15 after firmware update July 2020 the PV voltage is blocked at 16,3V and therefore the controller is not starting properly as the 5V threshold is not met. Can I go back to the former firmware? Can I reset the hardware? On full sunny day yesterday the charging was max 30% as normal
