The story : i've bought a ROG x670E-F Gaming Wifi and a Ryzen 9 7900xd3 for a new rig.
Everything went fine for the initial mount, and then i've seen that the bios was 5 versions away... so EZ Flash
First pass went good and then rebooted (EZ Flash)... second one went good and then rebooted (EZ flash) -> Message "successufly updated) and after the 3rd reboot : a last message, not in EZ Flash (just the CLI) saying update is finishing, keep it steady, and then shutdown and... death
No lights on the motherboard : it's powered up as i see a PCI Network card alive on it. But the MB itself it silent and in the dark. The Aorus leds next to the CPU are dead.
I've requested support on the ROG website, but in the meantime i wanted to try flashback, and here i need a bit of help
I've currently created a FAT32 USB Key, with MBR and only the flash file i need, but i never get Flashback to work : i simply have no led either on the USB Key or the Flashback led.
I've looked at some videos and i see that the motherboard should also show led activity when alive (the AORUS logo)
So my questions : Can Flashback also be bricked or that's impossible ? Or i'm missing something ? I've saw people saying that the CPU has to be removed, some saying the CPU power has to be removed, some about having only one RAM populated, etc....
Currently : I've got the motherboard fully naked (no CPU, RAM, etc...) just main power and CPU power connected. And still no lights anywhere.
