Moderators Jake Lo Posted July 19, 2021 Moderators Share Posted July 19, 2021 Give this a try. Have a backup bootable USB or place EFI in USB and boot with USB. If works, then replace into installed drive's EFI Note: Rename folder to EFI EFI-E5440_OC0.7.1.zip Link to comment Share on other sites More sharing options...
