Hey, all!
I have a 2010 cMP 5,1 basic quadcore cpu, in Mojave with a Sapphire Pulse RX580 8gb GPU. I have kept it mostly up to date, but it only had the 140.0.0.0.0 firmware. I recently ran the 2020-006 update and it seems to have bricked my machine. When it restarted, both monitors were black and have never come back. I let it run for about 5 hours, leaving and coming back to the same situation. I have tried everything I can think of to get it back.
I tried the original GT120 GPU to see if i could see anything as it booted, and so far no luck. Though when i still had the RX580 in, the monitor attached to that eventually turned half dark gray half light gray, and then fully light gray and then stayed like that until i unplugged it. I have also tried the long press on the power button until i get the beep and chime.
I have since pulled everything (optical drive, boot ssd, extra hdd, both gpus, all but 1 RAM stick).
When it boots, I get a chime and the power button is solid. When I press the diag button i get:
PWROK - GREEN
5V STBY - AMBER
SYS PG - GREEN
And that's it:
With no EFI DONE, am I at the end of the line with this backplane? Any thoughts on next moves?
Thanks in advance!!
Prior to this, I was having issues with the mac freezing periodically. I could move the mouse, but not click on anything or use the keyboard. After a bit, it would start working again. I am not sure if this is related to the issue at hand.
