i am really sorry, but i dont understand a single word :-(
Flashing the CCC-A via Most-Async can take 1 to 1,5 hours, over D-CAN/OBD much, much longer. Do you get any Error from the Flash-Tool while flashing the CCC-A?
If not, i would wait for min 1,5 hours (if your flashing CCC-A via OPS with MOST-Async)
It is normal that the BMW Logo shows up and the CCC restarts during flashing, because its starting a "coldboot" and then creating a Fast-Boot Image.
