2018 Sync 3 Update to v3.0 Build 18025 (Confirmed with Ford's new package)

[DukeGaGa]

If you have downloaded the update file before 3/26/2018, you'll need to go on owner.ford.com to download it again, the file has changed and removed a version check so it will install just fine on our 2018 Mustang.

Has anyone been able to update their 2018 to the latest 18025 build? Mine says already up to date when I try that, Ford customer support is no help saying the version I see on owner.ford.com is a mistake (which we all know it's not).

Also, I'm wondering if any 2017 owners out there can help me check your sha256 hash of your 18025 firmware file (with Nav)? If the hash is the same, I'll just try to downgrade to a v2.2 with and upgrade to v3.0_18025 to see if it works.

Well, just remembered I can add a 2017 to my account and download the update file for that car, and looks like it's not the same (haven't finished downloading yet, but the file size is different), so downgrading a 2018 using a 2017's file seems not the right way to go. Will check to see what files has changed in the zip.

Looks like I can modify the autoinstall.lst file to select which update files to use, will report back if it works.

I'm quite positive that removing the lines that references "HB5T-14G386-THA" will enable 2018s to install the update (also need to modify the numbers after removing those two lines):

• The HB5T-14G386-THA.tar.gz file contains no updates, just a utility of some sort (don't ask me I'm no expert in how Ford write their software, but I found it on some other website)
• It is item 1 on the list, makes sense to be a version check before doing everything else.
• There are a few lines of code that suggests this will stop the whole update process when detecting 2018 cars, see below. What this piece of code does is basically get the current version of your Sync 3 unit, then check if the current version is 3.0 or greater, and stop the update if that's the case. And apparently it also checks for model year, if it is greater than 17 it also stops the update.

# Check if HW is 3.2
if [[ "$MY" -gt 17  ]];
then
	exitUpdate $1
fi

# Check is SW MY18.5+
SW=$(grep "SYNCGen3.0" /fs/mp/Version.inf | awk -F_ '{ print $2 }' | tr -d '[:space:]')
if [[ -z $SW ]];
then
	exitUpdate $1
fi

MAJOR_MY18=3
MINOR_MY18=0

MAJOR=$(echo $SW | awk -F. '{ print $1 }')
MINOR=$(echo $SW | awk -F. '{ print $2 }')

if [[ $MAJOR -gt MAJOR_MY18 ]];
then
	exitUpdate $1
fi

if [[ $MAJOR -eq $MAJOR_MY18 && $MINOR -gt $MINOR_MY18 ]];
then
	exitUpdate $1
fi

exit 0

I didn't drive my car today since a friend just got his and is learning how to drive a manual, and wanted me in the car just to be safe... anyways he agreed to test it later and we'll see if it works.

So apparently ford released a new package for 2018 yesterday, which removed a file prefixed AHH, which is the file that does the check for v3.0, so now you can update without modifying anything. Also, the update is a bit different than others, it only prompts once “completed”.

Good info.

can we install over if we did the first 18025?

 

[DukeGaGa]

big question: whats the difference between the new one vs the one that got removed? if both are 18025

They just removed the version check file so this update can be used as intended. All other files are the same.

I had my hopes up I thought they released an update to fix wifi popup

I tried to update 3.0 17xxx with this and no luck, it says I'm up to date.

Looking to downgrade to 2.2 and then back again to 3.0, anyone willing to share a 2.2 link to me, I can't seem to find it anywhere.

Thanks!

Please read the title, this is only for 2018 not 2017. But you can also try modifying your autoinstall.lst file yourself and try.

I can confirm this new package worked on a 2018 GT with NAV. Previously said no update available, this morning took 15 minutes while driving. Restart car - 18025 now updated. Thanks to the original poster!

 

[HizliBullet]

theres a newer package now, the new voice file, be sure to redownload..i dont know if we can stick the whole thing again just for one file without messing up previously installed files
