Dice seem to have probs by flooding bus with prog msgs, what is you dice?

All other programs that use dice should be closed...

VDASH has no way to return it to 206751...
Could the source code be modified to accept an alternative serial number or device name as an argument?

Just used NEO Hex Editor on the .exe going to check it out later today

it talks now, but the PIN I know as good, as I sent it to D5T5 and it works in VDASH to change settings in the CEM, isn't working.

I have a 2007 C30 P1, when i crack the CEM pin, is it then possible to add new ignition keys? And how would this be done? You can do it via VIDA but you have to buy original key and also software module in vida. i was quoted 350 gbp by my local Volvo representative, also local locksmiths cannot do it.. I have teensy and Arduino, and DiCE available so cracking the CEM pin would not be a problem. Do you have add the keys via reprogramming the CEM in bench mode?

you have to have the 2 codes that come from the new key/fob and also the IMMO pin

Hello everyone!

Thanks to all the posts and contribute there I was able to assemble a Teensy 4.0 to decode the pin of P2 and P1, it was quite easy.
By the posts I have seen I was also able to read the Flash from a P2 V70 2006 and got the 320kb flash from it.

Now my question is how to write the flash back to the car?
Any Ideas?

The CEMs have 2 codes, the long 6 byte code you can crack by teensy, or the 3 byte UDS code you can crack by dice.
Both codes are different but have the same might... By the 3 byte UDS code you can read the flash by UDSreader and in flash you also find this 6 byte code...

This reads flash by 6 byte code:
