Just to update everyone here if they are having issues with getting their firmware updated. I just picked up my 2017 platinum energi from my dealer after they worked to get the modem updated. Everything is now working as it should. They tried to perform the software update but it still did not seem to work. They then contacted the Ford Techline for assistance and after about 4 days and possibly some stumped engineers they responded and gave the tech some diagnostics to check. After going through those they determined that the modem needed to be replaced. After they ordered that in the were able to program it properly and let me know it was finally working as it should. Picked it up from my dealer, which by the way is not an EV dealer, and was able to immediately register the vehicle and utilize all the app functions. If you still are having issues with not being able to get the firmware updated to 1.4.4 then I would suggest having them contact the Ford Techline for assistance since they are probably well versed in this issue now. Hope this helps
