[help] 820-00840: no ssd, no usb, wifi froze

[phantomEVO]

i don't know the history of this board…I'm pretty sure that u3900 was touched/changed (i don't know why)

Motherboard boot with “no disk error.”

Tried another disk, same error!

It can't see usb bootable from both usb

USB stick light stay on fixed

As soon as i try to boot in Recovery and write the password, it hangs, and then reboot

any help?

i try to summarise

i have activy led for both usb

i can't boot any os from both usb

ssd not seen (even with another ssd)

if i go in recovery, as soon as i insert wifi passord, mac hangs and reboot

ic camera was 100% resoldered (i don't know why)

usb ports were 100% resoldered (i don't know why)

i'm pretty sure that cd3215 were changed (they have different serials)


i think i can't boot in safe mode because ssd is not seen


i'm pretty sure that usb and ssd not seen is the same problem

u8640 not present...i don't know if it is normal...

i've another identical motherboard and it hasn't u8640 too
