Sony released a minor update for the FX3 and FX30 cameras but almost immediately withdrew the firmware. If you have already downloaded the update package I recommend you do not install it.  There may be a bug in the firmware. Sony are investigating to understand whether there is a bug or something else causing an issues that some users have reported. So for now, don’t do the FX30 version 1.01 or the FX3 version 2.01 update, wait until Sony have had a chance to look into the situation. It remains safe to continue to update version 1 FX3 cameras  to Version 2.00, it is only FX3 version 2.01 and FX30 version 1.01 that is affected.
