champcohort Posted November 15, 2008 Share Posted November 15, 2008 I want to update to EFIfirmware Update 1.5.1 and I follow all the step until the step that click the "Shut Down" and then it says: "An unexpected error occurred (28 : 3) Your firmware can not be updated" And search through the Apple support website as it said and can not find anything. So could anybody help me, please? P.S. my BOOT ROM version is: MBP31.0070.B02 I did try the other older firmware, but it said: This Mac does not need this update (I dont remember exactly but something like that ^^) Link to comment https://www.insanelymac.com/forum/topic/136635-please-help-i-can-not-update-efi-firmware/ Share on other sites More sharing options...
