Hi

By Modifing Data Into Eis, The Eis Now Is Corrupted And Can't Accept Any Key, All Key Position Are In Corrupted

What You Can Do, Is Try To Renew The Eis Again, And Write Original Untouched Data Back That I Hope You Saved Before You Modify,

In Otherwhise, Post Part Number Of The EIS, Then We Proceed

Regards

I had one off these dealer eis, that i bought as a spare.
To adapt it, i found a matching eepr and flash.
Wrote it with a programmer. So it whas no longer a dealer eis.
Then i made it virgin, and wrote the eis data back in using the ir mb cgdi wirekey.
That might work for you.

I never had any problems adding keys to dealer eis before.
Only ones, cgdi gave me the wrong special passw.

Test this dump or you will need to search for a dump from the same EZS and transfer data.

Hello your EIS W639 is a dealer EIS and you cannot write it over obd once it is erased, best solution for your problem is to write an eprom of the same eis using VVDI prog or any programmer that can write back EIS over bench, and erase it again and write back ori data.

According to your dump(EPP_JTAG) all keys are disabled so no keys will work again,
as the result your EIS can't activate.
You can try use Enable password to enable key...

Or try write back the attached modified bin with CGMB.
I believe you will still able to write with CGMB,
If you have luck it will work again.

(You may still need to due with the ESL and ECU if keys are disabled in it.
hope it is not the case)
