Help Validate/Repair BMW EWS Dump

[EwellG]

Battery got installed with reversed polarity in my 1994 BMW 320 and damaged the EWS.

Got a replacement EWS and would like to try to re-use and fix what I have read from the damaged EWS.

I read the HC11 with Xprog and got the attached file.

I can read it with EWS Editor + TNT Enforcer but I cannot read it with Zedbull to generate a transponder chip.

Can someone please check if this dump is in good condition to be written to the HC11 of the replacement EWS?

If it is corrupted, would appreciate if you could rebuild it for me.

I thought of just editing the dump of the replacement EWS HC11 with the data I can read using EWS Editor. But was thinking I would have an out of synch rolling code and ISN number will not be the same.

Thanks Vanos.

Tried to open your file with Zedbull to generate transponder chip. It gives error - "undefined eprom data". Something in the original file I have is corrupt.

The dump I have from the used replacement EWS i will use can be read by Zedbull.

What I have done for the moment is to edit the HC11 of the replacement EWS. I manually entered the data I read from the old
EWS to the replacement EWS i.e. key data, codes, password etc.
I read it using EWS Editor + Enforcer. T

I will try and see if I can align DME to EWS.

Problem resolved yesterday. Thanks to the guys who helped out.

I got the data read from the damaged EWS and manually entered it into the dump of the replacement EWs. I used EWS Editor+TNT Enforcer to do this. Wrote it on the HC11 using Xprog.

After re-installation of EWS, starter cranks but no fuel and ignition. I did EWS/DME alignment with BMW GT1. Then the car started.
