Hello, is it possible to create the crypto file from OBD reading? I need to program it by unsoldering the eeprom to bring the cluster back to life...

Is this a RB4 cluster? have you tried: https://www.drive2.ru/l/471768829593126099/4. If you have a .def checksum error (this is only for vw/skoda/seat) (copied from VampireLo )
To remove the .def (dashboard checksum error) shown on the display at the place of daily mileage, you need to:
4.1 Simply change the coding to the one that was on the old dashboard, or if the coding has already been changed/does not change, simply recode it with the same encoding (go to the coding, save the same encoding, exit and turn off the ignition).
4.2 Remove the 15th fuse of the dashboard, or turn off the battery for a couple of minutes.
4.3 Once the ignition is turned on, the .def error should go away.
The essence of recoding is that the checksums in the dashboard firmware are recalculated and they are updated themselves! |

Thanks for answering, I'll look at it later, but the picture is vd0, what I need is to encrypt the reading via obd, and write it to the 93c86 eeprom directly with a programmer, do you know of any tool that encrypts and decrypts? Greetings |

did you manage to repair it? Would I need the cable, or would just the software work for me? If you still have the software, could you pass it on to me? Thank you, (I edit, because I wrote the text in my native language) |

well, it seems that I have managed to bring it back to life, but the poor thing is dying, it changes data on its own (all kinds of information and readings from the eeprom through obd)

According to the dejavu link the software + dongle is 65€
I dont have anything left from back then.
Carprog can do it too i think.
How did you solve it?

Well, starting from a reading of the vag k commander cluster, and with the encrypt and decrypt tool... but still there is something wrong, because it does strange things,

I am going to attach the script that I have entered to 93c86 with the programmer, to see if someone can tell me where the error is, because I think everything matches, but it keeps failing EDIT; I've been looking for info, and there must be 9 types of masks for crypto. I think I have compiled all 9, with a reading that I have saved with vag k commander and one of these 9 masks should be able to heal the cluster, although I have also read that if there were changes in the readings previously, some bytes would have to be modified, it's already working! |
