Firmware updates are not supported when using the Apple Thunderbolt adapter. The update itself will fail, but the back can be recovered by updating the firmware on another computer with a direct firewire connection. For IQ backs we recommend updating via USB or CF card. For all other backs please use a computer with firewire ports.


Caution! LightPhase models with serial number prefix BB00 have been excluded from this list because user firmware updates on this back are not recommended due to a unique hardware design. Users attempts to update firmware in BB00 LightPhase models may render the back inoperable.

Some of the Mac versions of the Firmware Installer Application can only be run on computers that will boot into OS 9 . Updating these backs using OS 9 will not adversely affect their compatibility to run with the latest versions of Capture One built for OS X. If firmware update questions arise please contact your Phase One Distributor or Dealer or Phase One Technical Support.
