Archive: Update all versions of Ford Sync 3 to the latest Sync 3.4 (Build 3.4.19200)

you need to set the theme correct in forscan, you can use the testing settings in bezel diagnostics to check this

yes, using the withnav file in step 2 will work fine though

Due to a missing na maps license we can't install Na maps the same as EU maps, therefore repeat the process from the start (downgrade if on 19274) and use the withnav file.

no sorry. provide your current IVSU's

Navigation or not navigation? if it's not navigation then the only difference is supported languages, US = canada, american, mexican / EU = German, Dutch, British, French

I just bought this one: https://smile.amazon.com/gp...

Not with these files, there are pre 3.2 map files around but I can't help with this as most are torrents

The base is the same regardless of region, just voice and logos really.

Russian forum use UCDS which is paid licensed software ahardware made in Russia. About 140eur . Due to the risks involved I don't want to explain the Apim flashing progress via forscan. It's bad enough when people cry saying there Apim software has broke because they fucked something up. I don't want to be responsible (even though I'm not) for the low-level firmware on these devices (essentially a bios) being screwed up by using some pre release version of forscan, it also supposedly takes 30 minutes plus with forscan UCDS can do it in seconds. With that slow of a flash many things that are unexpected can happen.

That said I will give a hint. There is discussion on flashing via forscan on the fordownersclub in the "sites discussing this guide" section.

I'm guessing you are the guy on the ford owners club forum?

This is the information that comes with the experimental forscan build... No link provided. But it's on the discord server.

This function is in testing stage. There are problems, known ones and may be not known ones. Please note you use it "AS IS". In no event shall FORScan team be liable for any direct or indirect damage, caused by use of this function. We strongly recommend to foresee an option to recover "bricked" module with another equipment (like IDS).

Short instruction:

The function is called "Module firmware update" and available in Configuration and Programming section. Content
consists of 2 columns: current assembly/calibration and available for programming. All the firmware files that included into
the assembly are displayed.

There are 2 filter checkbox on the top (enabled by default):
Only official branch - only firmware from official branch, this is what available in IDS. If this filter box is unchecked, all
possible builds will be displayed, but only compatible with current hardware
Only newer than current - this shows only builds that are newer than current. If you need older ones, uncheck this box.

Every firmware file has status indicator on the right:
- green - file is ready for programming and will be programmed
- yellow - the file will not participate in programming
- red - file is required but missing or damaged

There 2 options at the bottom:

- Force program unchanged firmware - if some file in the new calibration level is not changed, FORScan will not write it. This option changes the behaviour and all files will be rewritten.

- Switch *ALL* modules to programming mode (silence on buses) - in this mode FORScan will switch all modules on both buses to programming mode, to make them "silent". Unfortunately, this function properly works only on J2534 adapters with MS-CAN support. ELM327 kind of adapters and J2534 Passthru without MS-CAN can implement it partially (on current bus only) due to adapter limitations. This may cause serious panic in some modules. So it is recommended to use this option ONLY if there is no other way to program a module.

There are 2 buttons on the bottom:
- Download - download missing files from Internet ( Motorcraft site)
- Program! - start the programming process

It has to be counted that not all of firmware files are available on Motorcraft site (only those that allowed
for dealership).

Known problems:

- It is not recommended to use china ELM327, as it is impossible to guarantee stable work in there. ELM327 Adapters that proved their ability to program firmware:
-- ELS27 - original (clone may hang after 30-40 minutes of work)
-- OBDLink SX (doesn't support MS-CAN, so may need to be modified for it)
-- VINT-TT55502 USB (marked as Ford/Mazda/FORScan compatible, with HS/MS CAN switch)
-- VeePeak USB (marked as Ford/Mazda/FORScan compatible, with HS/MS CAN switch)

- We do not recommend to program power steering modules yet. This requires special procedure. Current implemenation bricks Mondeo 4 PSCM

- We do not recommend to program modules that have ECU Configuration * parts in their firmware, FORScan may not offer right file

FORScan shows summarized firmware size and estimated programming time in the warning dialog before start
programming. We recommend to pay attetion to these numbers, as programming time may be very significant (several hours).
Time estimate for J2534 adapters may be very inexact yet.

After the firmware update modules usually throw U2100 DTC. The following sequence of actions is enough to clear it:
- Run Module configuration programmin (As Built format) and load *AB factory configuration in there. Please prepare it
advance (download for Motorcraft site by VIN), as current version cannot download it in automated mode yet.
- write All (all blocks!) to the module. If configuration isn't changed change, FORScan will ask to confirm force write,
please confirm it.

After first successful connect to vehicle FORScan will create vehicle profile. We recommend to backup profiles, as they may be helpful in case of restoring.

What we would like to get in case of problems:
- short report about the problem
- FORScan debug information (FORScan.log and dump.bin)
- user logs (content of Log tab in the section Configuration and Programming).

Regards,
FORScan Team

Sorry I misread this, you need to follow the downgrade process. If you can't do this as can't touch the screen temporarily enter bezel diagnostics and testing settings then change theme and try again.
