So I had the same thing happen to me. Im sitting in one right now it keeps flashing stablitrack off. I attempted to do a full reflash as sugested.
Just keeps saying Stabilitrack is off in the cluster....
So i powered off and tried again.
Says Service Stabilitrack on the screen.
Pulled fuse and it starts erases ECM and then begins flash. But EFI live
EFI live repeats retrying previous block.....
