Another Black Screen After Update

I traded out the head unit in my 2015 F-250 to upgrade from Sync 2 to Sync 3. Once I started the process to upgrade to Sync 3.4 I got as far as the first screen that asks you to remove the USB (which I did not) but then the screen went black. I waited for 20 minutes and still nothing. The USB drive wasn’t even blinking. Right now nothing works. The unit appears to be dead. I’m hoping you guys can help me recover.

After reading several posts on CyanLabs forum it’s been suggested to try Forscan, which I have, to reset the APIM. The Forescan will read the APIM but at this point I’m not quite sure what the procedure is or which files that I need to restore my APIM.

Here is some background on the unit that I do have:

APIM Version: JB5T-14G370-ACD
MFG date: May 2018

Screen Version: VPGB5F-3901-AB
MFG date: June 2017

Previous Config
Version: 3.0.20204
Region: NA
Navigation: Yes (1.19)

Upgrade to Sync 3.4.20351 with 2.20 Nav

Any help would be appreciated. Let me know if I can supply more info.

Usually this can happen if you asbuilt is set to the GT theme or GT Animation. the other cause is if you have a MY20 car but thats not relevant here

A log file of your syn3 updater process would also be helpful

I’m assuming you mean the updater log file created on the USB?

My updater log file from the USB.

Run the APIM Interrogator Utility and post the file. It’s in the utility section of the Syn3 Updater.

Or this:
Tutorial: APIM Interrogator Utility - Ford / Guides & Info - CyanLabs Official Community

Did you have the Ford GT theme selected?

F150chief. I did try that from another one of your posts and didn’t get anything. My theme was set to the default Ford theme.

Can you see the asbuilt screen with FORScan?

If so, take a picture or save the asbuilt data and post it here.

I did take a screen shot of it the last time I was out to the truck.

Your asbuilt is fine.

So this is a Sync retrofit for Sync 2. This worked fine on 3.0.20204 before the update?

When you say the first screen where you remove the USB, was this before or after the screens with the Mustang and Ford logos with the green bar at the bottom? Did you ever see the logos and green bar?

If not, power cycle the APIM, (remove battery power) for 5 minutes, then try the update again with the usb you created. See if this brings it back.

Do not remove the usb until the update is over. It takes about 28 minutes. Place the vehicle on a charger or run it for the duration of the upgrade.

Yes this is a new head unit. The old head unit wouldn’t support a Sync 3.0 update.

No. I never saw the logos and the green bar. Right after the message to change the USB went out, the screen went black.

I did disconnect the head unit from the truck and took it to the work bench to separate the screen from the APIM to check for serial numbers and manufacture dates. It was unpowered for several minutes. Does that count as a power cycle or should I disconnect both batteries?

I think that should be good power cycle.

Since you never saw the logos (Boot install screens), you should be able to just continue the reformat. It seems you are stuck in reformat mode (or boot mode).

Use another usb. This is a common issue.

If you have a 3.0 drive, try that. (I don’t know if that will make a difference.)

I’ll give it a try. After I plug in the USB and restart the process, how long should I give it if the screen still remains black?

F150chief

Well, I took a 3.0 USB drive, plugged it in and drove around for 1-1/2 hours. The screen never changed and is still black. I refuse to believe I have a dead APIM since I can see the “As Built” data on FORScan. Is there a way to reset it to the original version through FORScan?

I did find the APIM data in FORScan. Hope this helps.

APIM - Accessory Protocol Interface Module
Part number: JR3T-14G371-CED (latest known: JR3T-14G371-CJG)
Strategy : HB5T-14G374-CA
Calibration: HB5T-14G375-CA

no, unfortunately not.

Well… Shoot.

Just out of interest, where did you source the apim from? Was it ‘new’ from an ebay or Chinese seller?

If I were you, I’d source a replacement apim from eBay or a crashed vehicle dealer, then sell your existing one on ebay as spares or repairs. If you buy well, you shouldnt lose much.

I don’t know if this will fix the issue, but you have nothing to loose. I think the unit might be stuck in boot mode, since you can still access it via FORScan.

Make a usb with the following:
In the root, place,
reformat.lst
DONTINDX.MSA (if you don’t have it, it’s optional.)

In the SyncMyRide folder,
4U5T-14G381-AN_1552583626000.TAR.GZ (available in the IVSU database on this site.)

The contents of the reformat.lst file, 1 entry:

4U5T-14G381-AN_1552583626000.TAR.GZ

If the unit is in reformat or boot mode, it should just install this file and boot to Sync 3.3.19052. If the unit is not stuck here, nothing will happen.

Another option, is to just do a regular install of that file.

Make a usb with the following:
In the root, place,
autoinstall.lst
DONTINDX.MSA (if you don’t have it, it’s optional.)

In the SyncMyRide folder,
4U5T-14G381-AN_1552583626000.TAR.GZ (available in the IVSU database on this site.)

The contents of the autoinstall.lst file:

; SYNC3 Consumer Assembly Upgrade - Only for Nav/NA assemblies.

[SYNCGen3.0_3.4.19052_PRODUCT]
Item1 = 4U5T-14G381-AN_1552583626000.TAR.GZ
Open1 = SyncMyRide\4U5T-14G381-AN_1552583626000.TAR.GZ
Options = AutoInstall

If neither of these work, the unit is locked up or bricked somehow.

Louage,
The new head unit with screen, APIM and USB port came from infotainment.com which deals in OEM parts which is why i spent the extra $$. The label on the APIM shows the unit was assembled in Mexico not China. I plan to give them a call and see what they can do.

Thanks

Thanks F150chief. I’ll give it a try and let you know.
