If you have already repaired the same clone three times, the PCB traces or the STM32 internal flash are likely worn out. At this point, consider:
Many clones store configuration data in 24C02/24C04 EEPROM chips. Corruption causes identification failures with VCDS.
Load the clean firmware flash ( .hex ) and EEPROM ( .eep ) files for version 22.3.1.
