Audi Delphi 81a035192e in bootloop, looking for emmc pinout or other ways to revive.

Hi, as in the subject the unit is in bootloop, restarts after couple of seconds from the boot after a failed attempt to replace AudioManager file over telnet. Now it does not give enough time to revert the process, bridging the two pins does not help either. Anyone with the knowledge of the emmc diagram or quadlock for uart would be appreciated, this is a valuable information to me so please do not hesitate to message if you can help.
Attaching pictures of the board for reference.
