Have a 2019 Expedition that I used Syn3 to upgrade to 23088 about a year ago. Have had numerous bugs with it, and I’ve tried everything I can find on this forum to properly format and autodetect install for the latest version, I’ve tried upgrade, downgrade, reformat options and all give me INSTL_ERR12. I’ve disconnected battery, disconnect fuse, multiple sequential soft resets (master reset freezes).
I’m attempting to identify where the issue might be, and following Chief’s guide I downloaded the Interrogator Utility onto a formatted USB. But even that is giving me INSTL_ERR12. Is there anything else I can try?
