CAS 2 Vin Change with checksum.

[henal]

Hi, Guys.

something i am doing wrong.

i have flashed the CAS2 with Winkfp but only short vin changes and not long vin.

I have tried most tools to change the long vin but it just doesn't accept it. even though the checksum is correct (i think)

i have then Manually calculated the checksum and modified it in hex editor but its not accepting it and the vin is showing "yyyyyyyyyyyyyyyyy" which is the same when vin is all ff in hex

i have calculated my checksum for WBAVC32030VA31631 to be "00" and used these hex values
57 42 41 56 43 33 32 30 33 30 56 41 33 31 36 33 31

can anyone look over it and tell me where im going wrong.

i don't mind donating some money for your time. since its only cas2 that has this checksum problem.

please note i have tried all most all the basic applications, AVDI dumptool, bmw ISN, + all the other ones and it shows correctly in them but when i plug it in the car it doesn't accept it and shows it as blank or yyyy

thank you.
