S3 Battery dead BMS

Hi all, I managed to repair some S3/X3 batteries with new fuses and the 150ohm resistors. But now the battery of my son’s bike has a complete dead BMS. The regular repair parts (fuses, mosfets,etc) are all ok but no response from the BMS, no communication between cartridge and battery (I am sure cartridge and socket are ok)

Anybody found the magic of the reviving the BMS?
