Syn3 Updater Log File

As requested by the template, provide the log of the USB you used.
But since you have a black screen and your vehicle is 2021, it seems you have just bricked your unit.
Either way, post your logs.

That’s not what I asked, that’s an interrogator log.
From that, the part number for the APIM is 5U5T-14G371-GMD.
What we need to see is your syn3updater log.
It’s on the USB’s root, or in the computer you used to create the USB.

It seem that I don´t have it. Problem became when I start NAV update.


Unless you erased it, you must have it.
Check syn3updater, the LOGs tab.

Here is the deal: your APIM is MY20.
If the log says you attempted a reformat or downgrade to update maps, then the unit is DEAD.
But I need to see the log to confirm that.

Right now, based on your description, I’m 90% certain this is the case.

If I have bricked SYNC unit , is there possibility solve it.If I have bricked SYNC unit , is there possibility solve it.

Sadly, no.
As a consumer, we do not have the required tools.

But the vehicle is still under warranty

But you didn’t use Ford’s method to upgrade, right?.
So that warranty is now voided.

I used official way for update.

Let me get this clear…
You didn’t use Syn3updater at any point?.

If you didn’t, upload the contents of the USB Ford Provided you.
Specially the autoinstall.lst file, or any other .lst file on the USB’s root.

autoinstall.lst (1.5 KB)
in attachment please find

Thank you. That’s the only .lst file, right?.

Also, does the unit work besides the black screen?.
I mean, does the audio work for example?.
Are USB ports powered?.

Yes, radio is working, USB is only flashing.

please see printscreen of usb

If you have used an official update take the car to ford for warranty

I unplugged sync fuse no. 15 position.

yes I will, but way they offering for owners and it isn´t working.

Thanks for time.
