Received the Xhorse ELV Emulator for my Mercedes 204 for a few days. Have used it with VVDI MB BGA Tool. And the test report, here you go…
1.Successfully used ELV Emulator in W204:
1). EIS: read data by OBD from EIS/EZS …… OK
2). EIS: get erase password ……. OK
3). password calc.: get key password through calc. process and 1 token used ……OK
4). EIS: save all data of EIS ……. OK
5). EIS: renew EIS/EZS through IR ……. OK
6). EIS: load back saved data …….. OK
7). EIS: write data to EIS/EZS …… OK
8). EIS: personalize ELV emulator in EIS/EZS unit – success….. OK
9). EIS and ELV now working and car start
10). ELV emulator/simulator from Xhorse have sound (unlock and lock job) almost as original ELV
After all this steps still missed VIN in EIS/EZS, and fault in ESP because not see VIN from EIS,
then finished with XENTRY and write VIN to EIS/EZS in EIS/EZS unit finished…. OK
erase all faults ….. OK
I renew W204 ELV emulator only through 2x click…no need any data or passwords.
Original metalic W204 ELS/ELV unit renew is different process and steps…there you need erase passwords to have.
I unlock NEC from 3x blocked W204 ELV, i think it take 3-5 attempts, each delay 100-1000 times cca, don’t know exactly now…

Special Instructions (2016.05.29)
The newest cars after 2015 with FBS4 EIS don’t support read data and password, we are researching it
Renew EIS and renew ESL require erase password.
We are building a new server for erase password. It will support all erase password after new server finished
Auto personalized ESL: Now only support auto personalized ESL with key password all 00,
we will support all the passwords in future (You can use “Personalize W204 ESL” instead before we publish new version).
In ESL window, you can input crypto password for auto personalize (no need renew EIS).
Crypto password need calculate with other tools
