Ah okay. I think I know what happened because it was the same issue with mines originally. Ask the dealer if they installed the updates in order or if they just installed the latest one? If they went to just the last one then it's going to fail. They did that to mines as well. First the tech installed last one but failed then he went through all the updates. They had to install it in order for it to get updated to the last one.
For mines, I had the following three installed.
Uconnect_8.4_UAV_IR19.12_NAV_RU_MY18
Uconnect_8.4_UAV_MR28.4_RU_MY19
UCONNECT_8.4_UAV_QR39.5,MY19-21-RU,WK
