Unfortunately none of those two versions works. Still the same error. I tried to save the service tag in the BIOS but after it reboots it's the same again. Like BIOS won't remember service tag and PC's always in the same loop. Thanks a lot for your time and effort....

Small Form Factor is a typo because I have micro versions? Or does it matter?...

Hello,
I bought two 5080 micro secondhand and tried to update BIOS on one of them. Strange thing to me is that BIOS version was 0.13.24 which I cannot even find on dell website neither I can find asset tags on support page. Not sure if I was scammed and those are just faulty computers but they booted once I got them and one is still working fine. I tried to update to lowest possible BIOS as first step and it failed. Unfortunately after update only black screen, no BIOS, no POST. I didn't make a backup before of course.😶 So I dumped BIOS from working one but I'm getting error about different...

Hi,
My name is Matthew and I'm here to hopefully find a solution for dell optiplex micro.
