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…

only try….failed…try….failed….try….success.

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
