Thanks

Maneged get flash with dice and "USDT" . Pin at 4e000 484172010746 .
Can some one chek please CEM is H 30786890
I found where is parametr in flash but how can i write back to cem using Dice . i dont have any other programmer . Car prog is on the way.
i tried lukes cemtool but it looks it dont work parameters are in dirent place.


Edit: CEM flash reader says wrong code.

Can i edit manualy cem parametrs and use cemtool to upload bin? does write addres matches or it will brick cem?

Ah perfect are you using an UDS dedicated device? , as I have gone down the UDS rabbit hole but am having some trouble finding a straight forward way of doing so. , I did go down the arduino rabbit hole but that was short lived as most of the repo's don't have any usable example code. , I have been using My DS logic analyzer to read some of the packets but that doesn't primarily support UDS only CAN & CAN FD

Thank you for your answer

I saved the pin CEM IMMO here :
https://d5t5.com/helpdesk/create/ticket/pin
but the key procedure does not work

However I have the following faults:

- 1er key CEM 6C41
- 2eme key CEM 6C43

what do you think ?

I can be wrong but to me CEM PIN isn't the same as CEM IMMO PIN, they are different, maybe someone else can confirm this ?

Hello
could you extract the immo pin from the dumps.
I need to reprogram a key
THANKS

@wormland Thanks

I just tested it doesn't work

here are the photos of the errors

PS: in vdash I cannot delete the bad immo pin code, perhaps a code conflict
