No boot from any device (DVD, HDD, etc.)Dear all: Thank you for having this forum fully working. My iMac 24" Aluminium (november 2008) can't boot, completely frozen,...
Answer to: No boot from any device (DVD, HDD, etc.)The testing sequence should be this way: Stage 1 - Check all external booting possibilities: 1.1.- CD/DVD with Apple's Original DVD 1.2.- USB with Apple's original restoration tool. 1.3.- NetInstall from Mac device 1.4.- NetINstall from Windows 1.5.- Firewire from Mac device Stage 2 - Firmware intervention... now back to Stage 1. Stage 3 - HW intervention... now back to Stage 1 At this point of the Stage 1, only 1.3 and 1.5 trials are missing, since I don't have additional Apple's device. Therefore I should continue Stage 2, firmware intervention. Since the BootConsole (ALT on boot) do not work at all, it is very likely to be the firmware. Apple's technical support has two different ways to restore the firmware when the machine comes for reparation: 1.- Propietary SW to reinitializate locked/corrupt firmware, based on machine's ID specific. 2.- CD Firmware restoration. At home I can only proceed with the method 2: Firmware restoration CD. So, this is my option.
