Chief Xhorse engineer solution:

With the Power Adapter, VVDI MB BGA Tool will be able to quickly acquire the data for W204.

To read the W204 EIS data, please use VVDI PROG ( please remove EIS first, then use VVDI PROG to read the eeprom dump data, then use VVDI MB prepare key file and make dealer key).
