Hello everyone, I have tried to update the MMI 3G of my 2014 Audi A5, following all the instructions I have read on the forum. The firmware I had installed was K0257 (HNav_EU_K0257_6_D1), and I wanted to update to version K0900 (HN+EU_AU3G_K0900[8R0906961EB]), after several reboots and installation attempts, it got stuck on the "starting download" screen and does not advance. I have tried to reinstall version K0257 again and it won't let me. Both the screen and the MMI have had to remove the fuse to prevent the car from running out of battery. Also say that the steering wheel controls have stopped working.
Now I have a beautiful brick

Please help !!!
