Issues with downgrade from 3.4.20021

My car is Lincoln MKC 2019 version: 3.4.20021. It often crashes. Now I want to downgrade, but it doesn’t succeed.

Please give the following information:

  • Desired target version
  • Full intrrogator log for/and APIM details (nav, no nav, region)
  • The log for the USB you are trying to use

I think you do not have enough free space to perform the downgrade, but I will wait to see more details before making that call. If that’s the case, you can free up some space by removing gracenotes.

Probably trying to install the Sync app, voice, and Gracenotes at the same time. Out of space. Remove Gracenotes, install only the Sync app and voice. Being you have a NON-NAV system, there will not be enough room for Gracenotes, most likely.

You are trying to install the same version?

The system downgraded…
; CyanLabs Syn3Updater Beta - downgrade FORCED Mode - Sync 3.3.19052 NA

Item1 = TOOL - GB5T-14G386-SC_85041.tar.gz
Open1 = SyncMyRide\GB5T-14G386-SC_85041.tar.gz
Item2 = APP - 4U5T-14G381-AN_1552583626000.TAR.GZ

Item1 = REFORMAT TOOL - 1u5t-14g386-cb.tar.gz
Open1 = SyncMyRide\1u5t-14g386-cb.tar.gz
Options = AutoInstall,Include,Transaction

Then the reformat has the same file…

What version is the unit on now?

My current actual version is: 3.4 20021

Go back to the Syn3 Updater and start over. The reformat.lst file is wrong. You need to downgrade to 3.3.19052 first before you do anything else in order to reformat to the latest version.

Your autoinstall.lst file needs to look like this…

Item1 = 4U5T-14G381-AN_1552583626000.TAR.GZ
Open1 = SyncMyRide\4U5T-14G381-AN_1552583626000.TAR.GZ
Options = AutoInstall

You will have 1 file in the SyncMyRide folder:

Once this is done you can either reformat or autoinstall to the version you want. Since this is a NON-NAV APIM, only install the Sync App and current voice file for your region. Since you are in China, you should be able to install Gracenotes also, but after the app and voice files separately.

Or the upgrade failed! VER_ ERR081

My car is imported from the United States. Which region should I choose?

From the XML you posted above:
Your Sync app is presently at 5U5T-14G381-EB. 842Mb Sync3 v3.4.20021
Your voice app is presently at 5U5T-14G391-EL. 189Mb Sync3 v3.2.19345
The APIM part number is JR3T-14G371-BED. (2018)
You have 2.6GB of storage available.

You region should be China since the voice file is -EL. Looks like it is set.

The error is:

There is an error in the autoinstall.lst file. This one is corrected.

Make sure there are no other USB devices plugged into the vehicle, including your phone. You might try a master reset and then try the installation again.

Did you use your autoinstall.lst or ver: err08

Another message to you is that APIM cannot be used normally at present. Every time the power is turned on, it will become English. Even if it is adjusted to Chinese last time, it will become Yi next time

That is because there is no phone paired to the vehicle. You can turn off the location services.

I think the one I gave you had the error. It is fixed…

How to solve this error?

It can’t be reset. After pressing reset, the screen is stuck and feels like a crash. To force a restart.

You will need to power cycle the APIM. The best way to do it is to disconnect the battery cable for a few minutes then reconnect.

It seems that you APIM has an issue if these things are happening. Maybe time to see Ford service.
