XZBMW  Winkfp signature check failed when flashing ZBE controller
I have an '10 E82 with factory navigation. I tried to update my ZBE controller in WinKFP and it stopped working after I flashed it. When I flash the module it completes 100%, then I get this error message:

Error 211
Code     Level     Module                 Procedure           Index    Text
2086       PABD     ZBE2                    PruefeSignatur   2493   Signature check failed 11FLASH,
NG_SIGNATUR_PRUEFEN (Programm)     
ERROR_FLASH_SIGNATURE_CHECK        
2086       Error      COAPI2.CPP       coapiRunCabd       6       Signature check failed SG_PROGRAMMIEREN
2086       Error      COAPIKF.CPP     coapiKfProgSgD2 19      Signature check failed
 
I’m using the latest daten files from ISTA-P 3.66 with k+dcan cable and 15A battery charger. I was able to flash my Combox, PDC, and DWA (these were retrofits) without a problem, but the ZBE keeps giving me the same error. I tried programming the ZBE in ISTA-P and I got the same error message. The ZBE shows up in INPA UIF with job status “OKAY”. Any ideas on how to get ZBE working again?

You need to use an ICOM to recover it. Your K+DCAN wrote incorrect data, so the selfcheck failed.

Alternatively, a K+DCAN cable flashed with the ediabaslib firmware (for the Atmega) will fix it as well. The Chinese K+DCANs all have a firmware bug for specific modules.

Or just buy it at bimmergeeks already flashed with fixed firmware.

Do you know where I can get this firmware for my k+dcan cable?

The fuses have to be set as follows:
Fuse
Value (hex)Low
0xFD
High
0xDC
Extended
0xF9

I found the firmware and the instructions here:

https://github.com/uholeschak/ediabaslib...are-update 

I ordered an AVR programmer so I can update the firmware. According to the instructions, you are supposed to set the low, high, and extended fuses to 0xFD, 0xDC, and 0xF9. I'm not sure what this means. Can someone explain this? Thanks in advance!

******* SOLVED **********

I updated the firmware on my K+DCAN cable and I was able to flash the ZBE controller without any errors. Thanks to everyone that pointed me in the right direction!
