If you connected the clone to the internet or used a newer version of VCDS software, the loader might have been detected, causing the AT24C02 EEPROM to be erased or written with garbage data, making the chip appear dead.
Attempt to force a firmware download/update from the tab.
Locate the specialized located directly next to the central ARM microcontroller chip. vcds 2231 hex v2 clone repair better
Open a programming software like AVRDUDE, select Atmega162, and perform a full chip erase to remove the corrupted/bricked firmware.
Most clone failures are software-related. Here’s how to fix them. If you connected the clone to the internet
If the interface is a compatible clone, it may re-flash to a working state. Making Your VCDS Clone "Better" and More Stable
