There are some rules to follow in order to downgrade a BMENOP0300 firmware:

- If the BMENOP0300 module PV version is lower than PV04 ( = PV01, PV02 or PV03) , It is possible to downgrade Its firmware to an older version.
- If the BMENOP0300 module PV version is higher than PV04, It is not possible to downgrade its firmware lower than SV 2.5.

This limitation is due to a new hardware implemented in the module, starting from the product version PV04.

A Notice is available in the module firmware history document:
