I had a perfectly working sync 2 with outdated software version. I downloaded the current version from ford sync site that it provided based on my vin. followed all instructions on website to a tee but the updated stopped at some point with the “Problem detected with usb storage device…” error and would not complete. I’ve tried the entire process multiple times with multiple flash drives and always get the same error. The system is unusable currently always waiting for a usb flash drive but i always get the same error every time i try one. Any help would be appreciated.
Sync 2 Flash updated failed with error "Problem detected with usb storage device..."
You should revert back to the previous build to correct the issue. Which build was original and which are you trying to go to?
