3.4.23088 -> 3.4.23188 / INSTL_ERR12

My 2019 Mondeo started losing settings after the car maintenance did some uppdates. The version is 23088. I tried to update to 23188 with USB but keep getting error 12.

Also tried Interrogator Log, Gracenotes Removal and RW Data Cleaner. Keep getting the same error 12. And the master reset freezes. Soft reset operates ok, but doesn’t fix my problem.

Is there anything to do, or is my Apim bad?

Your APIM is not bad, your manners clearly are.

1st post and not a hi, hello or even thanks?.
Surely that way of treating people is going to make them want to help you…

I’ve zero interest in doing that…
Good luck, maybe others will be more tolerant than me…

Thank you. I found solution. Everything works now.

Thak you!

Happy Thanksgiving. I am having the same issue as the original poster and would love some help if possible. I am running Sync 3.4 Build 23088 (non-nav). My screen keeps going black and I can perform a soft reset to get it all back. I cannot get a hard reset to run, the screen freezes up when I hit “continue”. When I insert the USB with the latest build I get Error Code: INSTL_ERR12. Any help would be greatly appreciated!

May I ask how you fixed it? I am having the same issue.
Thank you!

Assuming you are using Syn3 Updater post your log file.
