Looks like a striked out, got a black screen :frowning:
Tried 1u5T-14G374EK & 1u5T-14G374-DA
Didnā€™t get a chance to program the 375 file
Any suggestions

Fixed it, luckly using the 2.4.0 beta/test and original files dl through 2.4.2.
For some reason the newer version would flash but still black screen.

Same thing I got going to -EK. I got -EE to work but found no benefit to it so went back to 1u5T-14G374-DA and 1u5T-14G375-DA.

What vehicle and year? Is the APIM OE with the car? Iā€™ve seen a lot of folks with pre-2018 APIMā€™s have issues upgrading the firmware. Seems like the 3.2+ OE units do a lot better at this.

Hi no, retrofit but it was out of a 2017 Focus.
I donā€™t know if this matters but Iā€™m in Australia.
I know some parts of the firmware are unit based on region
This was my version, before updating to 3.4

Hi

short questions,

  1. Forscan will suggest best software for my APIM or I need to choose it from the list?
  2. how long it will take approximately to update firmware with STN2120 via forscan

thank you in advance

The latest firmware should automatically be selected for you from the list. You should save your current as built before flashing the firmware.

Not sure how long it would take with that adapter as Iā€™ve only used the recommended ones listed on this site.

When I tried flashing modules it took about 5 minutes each.

Hi

thank you for your reply

do you think that there is a sense to upgrade firmware in such situation like in the picture?

It seems like most of the firmware is already the latest one available. This is also what I get when I go to the firmware update page for my APIM. I would recommend just leaving it as is if it is working in order to avoid possible bricking.

Thank you for replay. I will leave it like it is.

The firmware upgrade process failed for me. Can my APIM be saved, or did I just destroy it?

Most likely we can rescue itā€¦
What model vehicle and year? Region?
Can you post what you did and the version you tried to go from and to?
Do you have the original Calibration files?
Can you post the current screen like above?
Did you use FORScan 2.4.2 ?

I followed the instructions, ran the test (it passed), then proceeded to program:

ā€¦somewhere along the way it just failed and the APIM was no longer detected by the PCM or other modules.

I am having trouble finding a place to download the original calibration files. All previous links reference a site that no longer publicly hosts the files, and the Ford Tech website canā€™t seem to find any file I search for.

I used FORscan 2.4.2 to update the firmware on the APIM. I was able to use it on several other modules first.

I am using an EX adapter. I do have the as-built file from Ford and I do have a saved vehicle profile in FORscan that has helped a little.

Unfortunately, I found all of the truly useful information, including what I should have done differently, after I bricked the APIM.

I will PM you later with a recovery plan. I have the files you need.

The strategy file -AF was the updated file? All the others look right for a 2016 model.
Does ForScan respond at this point when you try to change strategy file?

As I understand it, the left column matches my as-built data. The right column is a mix of values from the left column (presumably items that donā€™t require an update) and FORscan automatically populating values.

I cannot see the APIM with FORscan, but when I try to re-program it gets through wiping blocks and seems to fail after that. Iā€™ll see if I can get a snap of the log if that will help.

This is a very early Sync 3 APIM.
16 FORD F150 OEM SYNC MODULE ASSEMBLY GJ5T-14G371-CFC
It will not support the newer firmware, not recommended.
I will PM you the files for download.

By very strange coincidence I talked another US user through recovering from EXACTLY the same situation with an identical hardware part number (GJ5T-14G371-CFC) as yours. For the reference of anyone reading, we did a force program using the following software part numbers:

GB5T-14G376-AA
GB5T-14G374-AF
GB5T-14G375-DA

Please contact us if you need us to provide these files.

I think the forscan version update for GJ5T-14G380-BC is buggedā€¦

I placed the files on a share he has access to. Thanks for the confirmation on the recovery, thatā€™s what I told ss423 to do.
