I tried to install it on my '19 Lincoln and the system rebooted after about 20-30 minutes and booted into 3.4 and went back to Updating System Software. From there, it rebooted again and booted back into 3.4 and said Updating System Software... sat on the screen for 10 minutes and rebooted again and showed Updating System Software. It did this endlessly until I pulled out the USB upon one of the reboots. Is this normal? Coming from 3.3 19052. 3.4 seemed to run fine after pulling out the USB but I'm wondering why it was doing that. I just used the USB3 files as stated for 2019 vehicles with 3.3.
With it in the USB port, it thinks there is another update into infinity until the drive is removed from the port after an update. It does NOT check to see if the update on the drive is already installed.

I would put the usb in, pull your cable and put it back to force a reboot. Start it and let it run 15 mins and see if any update on progress

yeah. Keeps rotating the Mustang loading screens. If I try to use the USB 1 it errors out and says. Error update packages not found.
edit: I’m assuming it’s wiped. Given the loading screens

Although, in the past when I've done SYNC 3 updates, I didn't have to remove the USB drive and it had said installation complete after the reboot. It's the first time I've experienced a loop like that without removing the thumb drive.
