There are two update packages for firmware version 3.0.1.

If you want to update a camera with firmware version 2.2.1 or below, 
you must choose the update package from the "Update_from_fw_v2.2.1_or_below" folder.

If you want to update a camera with firmware version 2.3.0 or above,
you must choose the update package from the "Update from fw v2.3.0_or_above" folder.

If you upload the wrong package, the update procedure will fail. The 
camera won't be damaged, though, and can be still be updated by uploading the correct package.

An attempt to upload the wrong update package will trigger the following error messages:
