FYI, according to the Swiss importer of Energicas, and Energica itself, there is only one version of firmware 042 and that runs fine. There was, however, a problem with the software that installed firmware 042. The issues encountered by early firmware 042 adopters are considered to be caused by a bug in said software, not the firmware. I can't verify that myself but the explanation sounds plausible to me as the meta-data of the firmware seems to be identical.
