Xhorse VVDI 2 device has proven to be a reliable tool for reading and writing data from various car models. However, during an attempt to write data to an IVECO Stralis EEPROM 25c640 chip, I encountered an error message stating “Unknown version.”

The issue might be related to the chip’s manufacturer selection during the reading process. An incorrect manufacturer might have been chosen during the initial reading, resulting in the “unknown version” error message when attempting to write data.
To address the problem, we advised you to carefully examine the silk screen of the chip. The silk screen is the label or marking present on the chip’s surface that typically includes information about the manufacturer and other relevant details.
By paying close attention to the silk screen, you can determine the correct manufacturer and select it accordingly during the reading process.
